Propylene characters are formed by combining propylene characters according to their shapes. There are three names in the standard: 1: a: flat drum character b: sharp drum character c: round drum character. Other shapes are basically evolved from these three. For example, a pointed drum can evolve into a diamond, and a round drum can evolve into an arc, but the choice of knives and the depth of knives are different, and the shapes of characters are completely different. A: Production and requirements of flat drum characters: use copy paper to trace the required characters on the density board, leaving 5cm on each side, install the corresponding straight knife with a manual engraving machine, and open the mold along the outer line of the characters (the inner line follows, others follow the outer line). After the mold is opened, flatten the mold with a file. Then use a file and sandpaper to polish the sides and corners of the convex and concave dies of the characters into circular arcs, which must be smooth and even, and finally use sandpaper to polish them smoothly. You can also use a computer engraving machine to carve the mold, and after adding enough height, you can smooth the edges and corners. B: Production and requirements of sharp drum characters: Step 1: The production method is the same as that of flat drum characters, except that the sides and corners are not polished into arcs for the time being. Step 2: heightening and molding. According to the size of the word and the width of the stroke (the widest pen has high cost performance), draw a middle line from the second floor to see if the inclination of both sides is 90 degrees right angle, and use this angle to locate the heightening thickness. Then choose a suitable 45-degree bevel cutter and install it on the multi-function milling machine. Literally, open a sharp drum downward, and use 502 glue or three-second glue to drop glue on each part where the sharp point is gradually punched. This is relatively hard, and the mold will not be damaged when pressed, and there is no sharp point. C: Production and requirements of round drum characters: Step 1: The production method is the same as that of flat drum characters, except that the sides and corners are not polished into arcs for the time being. Step 2: heightening and molding. The increased thickness should be proportional to the size of the characters, and the things made in harmony are beautiful. The steps are roughly the same as the sharp drum characters, except that the knife is a round knife. 5. The production requirement of acrylic light box bottom plate is 1. The four sides of the bottom punch should be smooth, and the four corners should be ground into arc and inclined shape (that is, the four corners are narrow at the top and wide at the bottom) to facilitate demoulding. 2. The bottom of the concave die of the bottom plate can be polished with sandpaper, and the angle should not be too large, so that the gap between the two bottom plates can be narrowed. VI. Calculation method of acrylic light box bottom die There are two calculation methods for acrylic light box bottom die. Both of these algorithms are aimed at the bottom plate which is divided into several equal parts. In the first case, the algorithm of dividing the mold into several blocks horizontally or vertically is as follows: 1, and the total length minus the margins on both sides of the bottom plate is equal to the total length of the remaining molds to be manufactured; 2. Divide the total length of the remaining mold to be manufactured by the number of equal blocks, which is equal to the size of the mold to be manufactured; 3. The size of the total width minus the margins on both sides of the bottom plate is equal to the size of the die to be made; Minus 5 mm from the size calculated by 2 is the gap loss (that is, the loss of poor splicing) when two bottom plates are spliced. 5. After the molded acrylic base plates are spliced together, the length of the final overall size is found on both sides of the base plates. In the second case, when the mold is divided into several blocks horizontally and vertically, the algorithm is as follows: 1, and the total length minus the margins on both sides of the bottom plate is equal to the total length of the remaining molds to be made; 2. Divide the total length of the remaining mold by the number of equally divided blocks, which is equal to the size of the mold to be made; 3. The total width minus the margins on both sides of the bottom plate is equal to the total width of the remaining molds to be made; The total width of the remaining mold to be made divided by the number of equally divided blocks is equal to the size of the mold to be made. 5. Subtract 5 mm from the size calculated by 2 and 4, which is the gap loss (that is, the loss of poor splicing) when two bottom plates are spliced. 6. Splice a plurality of molded acrylic baseboards together to find out the length of the final total size. Seven. The margin size of molded acrylic characters and the bottom plate is 1. There are three kinds of margins for molded acrylic characters under different conditions: A: When the characters are spliced with the bottom plate, there is a margin of about 3 mm. B: Leave a margin of about 1 cm when the box is made by itself. C: After the characters are pressed, it is necessary to manually enclose a few centimeters, and the size of the left edge of the characters is about 5 mm 2. The size of the edge of the bottom plate is about 2 to 3 cm. 8. The words are hollowed out after sticking to the bottom plate 1. Step 1: Invert the pasted bottom plate on the female die, and put a fluorescent lamp at the bottom for illumination. 2. Step 2: After the light shines, you can see the hollowed-out part of the character. Use a hand electric drill to drill a hole slightly larger than the blade diameter of the edging knife, then install the edging knife on the woodworking edging machine and put it in the middle of the drilled hole (the depth of the knife is slightly larger than the thickness of the plate) for hollowing out. IX. The optimal number and installation method of fluorescent lamps and LEDs installed in the box 1, the number of fluorescent lamps is 4-5 per square meter, and the lights on both sides of the box should be as close as possible to the box, because the reflection ability on both sides of the box is weak. 2. How many leds are installed: A: Quantity: the LED spacing is 8cm X8cm, and it can also be placed at the spacing of 8cm X 10cm or 10cm. At present, there are many LED manufacturers in the domestic market, and the materials are inconsistent, resulting in uneven quality. Therefore, please consult the buyer or the consumables department of our company about the installation and the height of the box. The above contents are for reference only. B: Installation: After selecting the position of the LED at the bottom of the box, first glue it with 502 glue or three seconds, and then hit both sides of the LED with dry glue or glass glue. X. performance and precautions of LED 1. LED has the advantages of low power consumption, high brightness, anti-vibration, high reliability, long life, no pollution, bright colors and so on. It is a real green lighting. The service life reaches 654.38+ million hours. 2.LED can emit red, yellow, blue, green, white, orange, amber, blue-green, red-green, yellow-green, pure green, emerald green and so on, and can be changed into red, yellow, blue, green, white, cyan and purple by numerical control. 3. There are two kinds of LED light source modules encapsulated by metal shell: ZLS-PMB and ZLS-PMBC. Answer: ZLS-PMB light source board realizes side lighting, which is suitable to be installed on the side wall of luminous characters and illuminates the luminous surface evenly through reflection. The installation is simple, and the inner wall of the letter is required to be coated with reflective material. Generally, it is 3cm away from the light box, and the height of the box is generally required to be above 7cm. B: ZLS-PMBC light source board realizes front light emission, and is suitable for being installed at the bottom of luminous characters to directly illuminate the luminous surface. It is required that the width of the word slot is above 4cm and the height of the box body is above 4cm. The contact part between the light source board and the light box should have good heat dissipation. 4. The center distance of each light source board is generally 10cm. 5. When the width of the word slot is less than or equal to 10, when using the ZLS-PMBC light source board, generally only one side can be installed to ensure sufficient brightness; When the width is between 10-20cm, the light source panels should be installed on both sides and staggered as far as possible; If the width of the word slot is more than 20 cm, the ZLS-PMBC light source board should be installed in the middle of the bottom of the word slot, and the spacing is about 10 cm. 6. The standard package of the light source panel is 5 in a string, and the red light source panel can be connected with 6 strings (30 pieces) at most, and the extra 30 pieces need to be looped again; At most, there are 10 strings (50 pieces) for light source boards of other colors, and the extra 50 pieces need to be re-looped. The power supply should be connected to the switching power supply, and the distance between the power supply and the light source should be as small as possible. 7. Connect the wires with connectors, and the ends do not need to be peeled. Just peel off the thread end until it reaches the bottom of the connector, and then press it with pliers. 8. The terminal end of the last light source board shall be wrapped with waterproof tape. The above contents are for reference only. 1 1. The choice of tools when making molds is based on the thickness of acrylic board. There are the following situations: 1. Hand-made mold: A: The thickness of the mold is below 3.5 cm, and the tools are made of the same thickness. B: The die thickness is greater than 3.5 cm, and the cutting tool is selected to be slightly greater than the plate thickness1-2 mm. According to the die thickness, the slightly larger cutting tool is selected. 2. Make a mold with a computer engraving machine: A: The thickness of the mold is below 3.5 cm, and the cutter is the same thickness (because the cutter size and thickness of the engraving machine are slightly different, you can choose a cutter with a similar thickness, and the cutter with a large thickness can only choose a large one). B: The die thickness is greater than 3.5 cm, and the cutting tool is selected to be slightly greater than the plate thickness1-2 mm. According to the die thickness, the slightly larger cutting tool is selected. Twelve. Relationship between character size and die thickness 1. Pointed drum: according to the sharpness of the mold, the thickness can reach the height within the allowable processing range of the equipment under the proportion of 90 degrees right angle. 2. Drum-shaped characters: in the case that the size and thickness of the characters are proportional, harmonious and beautiful, the thickness can be very high if the equipment allows. 3, flat drum type: A:60-70cm font mold thickness can be about 4 cm, the mold is slightly inclined; The thickness of 90 cm-1 m Chinese character mold can be about 6 cm, and the mold has inclination; The thickness of the Chinese character mold above 1 m can be about 8 cm, and the mold is slightly inclined; The thickness of the 2-meter Chinese character mold can be about 10 cm, and the mold is slightly inclined. The above parameters are for reference only. Thirteen. The plastic absorption requirement for acrylic characters with characters less than 20cm is 1, and the thickness of the mold is1.5 cm ... 2. The mold should be made by engraving machine. 3. The gap between the male die and the female die is the thickness of the acrylic plate. 4. After the female model has carved the inside of the word, grind it down. Let the gap between the inner male die and the female die be slightly larger than the thickness of the acrylic plate. 5. The four sides of the punch, that is, the corners, should be sanded, and the punch with small or narrow strokes should be glued with 502 glue or 3 seconds glue to make the surface hard and not crushed. 6. After the male and female molds are repaired, stick the male mold and female die of Chinese characters on two density boards with slightly larger size and font, and align them. When the platform presses the quick contact die, the touch switch makes the platform slowly descend to the position where the plate is pressed, and when the die is lifted, the touch switch should also be touched until the punch and die are separated from the platform that rises or falls steadily. The small-print extrusion plate is easier to absorb pressure, and the height of the forming die can be increased appropriately. Fourteen What is the suitable thickness of acrylic light box bottom plate 1? Three thick plates are only applicable to the bottom plate of acrylic light box about 1 m. 2. If the area is too large, exceeding 1.5m, physical characteristics such as bearing capacity, flexibility and tensile force of the board itself should be considered. According to local weather conditions and wind power, 4-5 thick boards can be selected. 15. Common box wrapping materials and box making materials 1, wrapping materials: iron wrapping, aluminum wrapping, aluminum-plastic wrapping, etc. 2. Materials for making the box: square pipes are painted with iron paint or aluminum-plastic plates and aluminum profiles. 3. Box material of single character: 0.8- 1.2 iron sheet is used as the box, which is cheaper than other materials. XVI. The heat dissipation of acrylic substrate and acrylic character 1, according to the physical characteristics of acrylic board, the best heat dissipation time is 24 hours, and it takes at least 12 hours to use. 2. Cooling method of the acrylic substrate: After the acrylic substrate is taken out from the platform, brackets are put on the bottom of the four sides in turn, so that the substrate is suspended, and the acrylic substrate is not allowed to touch the ground. The middle part of the upper part of the four sides of the acrylic bottom plate is compacted with heavy objects, and then the surface is lightly pressed by hand, and at the same time, the dust gun is used to blow air, so that the reverse side is quickly cooled and shaped. It can be used after being pressed for a period of time. 3. Cooling method of acrylic characters: Take the acrylic characters out of the platform, put them in a flat place, and press the four sides with heavy objects to prevent the bottom from deforming. Seventeen. Manufacturing method of arc bottom die 1 First, use wood board or 1.8 thick density board to make the required radian, and the standard radian ratio is 1: 3.25 (for reference only). 2. Cut the required size with the density board with a thickness of 0.9 or 1 cm, and put a complete arc on both sides of the bottom (if the density board is bent, nail the two arcs together to increase the strength). Nail the density board and radian together with an air nailing gun. Nail a few radians in the middle, and nail the other two sides with straight MDF. 3. The master mold is the same as the original method. 4. After the male and female molds are finished, the four sides of the male mold should be treated with sandpaper or file to make the corners slightly smoother. The corners are slightly inclined to facilitate demoulding. The bottom of the female die can be polished. 5. No matter how big the radian in the middle of the arc bottom die is, try to ensure that the height of both sides is about 3 cm. The molded board is too high to be lifted, and the four sides are easy to crack. 6. Finally, pressure suction molding. 18. How to make the curved font 1. First make the same radian as the bottom die, and according to the size of the characters, take a part slightly larger than the font in the middle of the bottom die radian. When making this arc, there is an inner arc and an outer arc to keep. 2. Make a mold with the same radian as the bottom plate and nail it to the end with a whole plate. 3. When using 0.9, 65, 438+0 or 65, 438+0.2 density board to make the mold of arc-shaped characters, the choice of density board thickness depends on the size of the characters (because the thickness, size and material of density board determine the degree to which it can bend). 4. Nail the punch of the finished word on the finished arc plate layer by layer, and nail the female die of the word on the inner arc. Because the radians of the inner and outer arcs are the same, the combination of convex and concave dies behind the inner and outer arcs is exactly the same radian. Nineteen. There are two methods for installing yellow strips on oil floors in China: 1. The first method: after the yellow strips are pasted, they are directly pasted on the floor that needs to be pasted, which is an old-fashioned practice. 2. The first method: on the bottom plate, use a stone knife or woodworking trimmer to cut off the position where the yellow strip needs to be bonded according to the same width (only one third of the side surface of the cut part of the bottom plate needs to be cut off). It is necessary to embed the finished yellow strip in it, keep it flush with the bottom plate and stick it with glue.
