What kind of problems need to be solved in the design and manufacture of injection molds?
1. Reasonable structural selection: According to the drawings and technical requirements, select the appropriate molding method and equipment, combine the factory capabilities, and give the structural plan of the injection mold. In the process, the opinions of relevant parties can be combined for comprehensive discussion and research.
2. Injection mold molding parts size standard: The molded parts are very important, which determines the shape, size and quality of the plastic parts. The average shrinkage method is usually used for calculation. If the accuracy requirements are high, the tolerance band method can be used for calculation.
3. It should be easy to manufacture: When designing, it should be as cheap and easy to manufacture as possible.
4. Injection mold parts should have good wear resistance: Good wear resistance means that its service life will not be bad. When designing, it is necessary to put forward necessary requirements for materials, processing methods, heat treatment, etc., and it is also necessary to consider how to facilitate adjustment to avoid the inability to replace parts when they are damaged.
