What is the process for the upper and lower mold examination of Dongguan Yigao Injection Molding Department?

Molding:

1. When receiving the production order for white or high-gloss products before mounting the mold, prepare 2 hours in advance. First, the technician will pull the mold to the injection molding department. The maintenance team notifies the maintenance personnel to clean the oil stains and oil spots in the mold cavity. After cleaning, the upper mold is produced;

2. The mold is lifted from the area to be produced to the production machine (repeat 4.4.5 for the hanging mold). Similarly, when the hanging mold is traveling, it cannot be higher than 30CM from the ground.

3. The mold loading personnel should check and clean the fixed and movable mold bases, whether the screw holes are intact, and whether the length and position of the ejector pin match the mold.

4. Start the motor to adjust the thickness of the injection mold to be slightly larger than the thickness of the mold.

5. Lift the mold and put it into the injection molding machine, install the positioning ring and adjust the position of the mold.

6. Turn the injection molding machine to the mold adjustment button, close the front and rear safety doors, lock the mold until the elbow is straightened, and press the mold adjustment forward button until the front and rear templates are completely aligned with the injection molding machine and the movable mold base. clingy.

7. The front and rear molds each press 4 pressure plates (the number of pressure plates needs to be increased when the mold is larger). The thickness of the pad iron cannot be less than the thickness of the template. The depth of the screw into the thread is preferably twice the diameter of the screw. .

8. The pressure plate of the three-opening mold should not be too close to the material head plate, and a distance of 2-3mm is appropriate.

9. Use appropriate reinforcing rods to tighten the screws according to the size of the mold.

10. Install protection switches, core pulls, etc. according to the mold structure.

11. Open the mold slowly, connect the water supply (note: test whether the water supply is smooth), first use rags and mold cleaning agent to clean the mold cavity and parting surface.

Lower mold: 1. Prepare the water tray and place it next to the machine, turn off the water transport switch, and remove the water transport pipe (note: the order of removing the water pipe---down first, then up, side first, then up), If there is a water nozzle under the mold, it must be removed. For molds with core pulls, take the oil pan and then remove the core pull oil pipe and replace the bulkhead screws.

2. Use an air gun to blow away the water in the mold and the accumulated water in the mold cavity, and then use a rag to clean up the foreign matter and impurities on the parting surface of the mold.

3. After proper maintenance of the mold, spray anti-rust oil (parts to spray anti-rust oil: mold core, guide pillar, slider, ejector pin, runner).

4. Start the motor and close the mold (note: high voltage cannot be used when clamping the mold).

5. Screw on the lifting rings and hang them on the driving hook or sling (pay attention to the parallelism of the mold when lifting the mold, and screw on two lifting rings if necessary).

6. Remove the pressure plate, open the mold slowly and lift out the mold.

7. Send the mold to the mold storage area (note: it is strictly prohibited to stand under the vehicle when the mold is being hoisted, and the height of the mold cannot be higher than 30CM from the ground when the mold is being hoisted).
