The main points of injection mold design

When designing the injection mold, the structure of the injection mold should be as compact as possible and the operation should be convenient, and the parts of the injection mold should have sufficient strength and rigidity. The rounded corners are excessive to avoid excessive stress concentration; for the injection mold concave mold, cavity and part of the punch, core can use a combination or mosaic structure to eliminate stress concentration, slender punch or core, in the injection mold structure Appropriate protective measures should be taken on the top; for cold stamping dies, devices should be equipped to prevent clogging of parts or waste. At the same time, it is also necessary to consider how to reduce the impact on the quality of the injection mold caused by the wear of sliding fittings and frequent impact parts in long-term use.
