Die Parts Die Structure Injection Molds

When the die structure allows, the corner of each surface of the die parts should be designed as rounded as possible to avoid stress concentration.For concave die, cavity and part of punch, core, can use combination or Mosaic structure to eliminate stress concentration, slender punch or core, in the structure should take appropriate protection measures.

For injection molds, devices should be provided to prevent blockages of parts or waste materials (e.g., bullet pin, compressed air, etc.)

At the same time, we should consider how to reduce the influence of sliding fitting parts and frequent impingement parts on the quality of die.

In the design, it is necessary to reduce the range of disassembly during the maintenance of a certain part, especially the replacement of vulnerable parts.
