What are the main design contents of injection mold CAD? Injection mold CAD provides great convenience and advantages for the design of injection mold, and will have a great and far-reaching impact on the mold industry. The main design contents of injection mold CAD are: 1) geometric modeling of plastic parts. Geometric modeling of plastic parts is the first step of design. It uses the geometric modeling system in CAD, such as wireframe modeling, surface modeling and solid modeling, to generate the geometric model of injection molded products in the computer. Because plastic parts are mostly thin-walled and have complex surfaces, surface modeling is often used to generate geometric models of plastic parts. 2) The generation of cavity surface shape. In the injection mold, the outer surface of the plastic part is generated by the cavity and the inner surface is generated by the core, which together constrain the plastic part and generate the surface of the plastic part. When geometric modeling is generated in a computer, it is used to generate the surface shape of the molding cavity. Because all plastics have different degrees of molding shrinkage, CAD should modify the model shape according to the shrinkage value, and then generate the required cavity surface shape. 3) Structural design of injection mold. Using computer software to determine the best number of cavities, guiding designers to arrange cavities, conceiving gating system, cooling system and demoulding mechanism, and preparing for selecting standard die sets and designing moving and fixed die parts drawings. 4) Select the standard module. In injection mold CAD, there is generally a standard mold base, and the required mold base is selected from the mold base. The design software used for the selection of standard formwork should have two functions: one is to guide designers to import the standard formwork of enterprises and establish a special standard formwork library; Secondly, it is convenient to select the type of mould base and the graphics and data of all mould standard parts needed for this design from the established special standard mould base. 5) Assembly drawing and assembly drawing generation. Injection mold CAD can guide designers to generate mold assembly drawings and assembly drawings in an interactive way according to the selected standard mold base and the completed cavity layout. After completing the assembly drawing, you can drag the mold parts on the screen with the cursor and assemble the mold assembly drawing through the building blocks. 6) Generate the die part drawing. After the mold assembly drawing and assembly drawing are completed, injection mold CAD can guide designers to complete the design, drawing and dimensioning of mold parts. 7) Routine calculation and inspection. Injection mold CAD can combine theoretical calculation with effective design experience, provide comprehensive calculation and check of mold parts for mold designers, and ensure the correctness of relevant parameters in injection mold structure.
