齿轮凸轮组合件注塑模具设计

摘要

通过对齿轮凸轮组合件成型模具的分析,提出了利用动模上滑块对一个凸轮进行抽芯、利用分型面对另一个凸轮脱模的方案,解决了凸轮脱模问题对模具的动模滑块设计、定模型腔块设计、动定模定位设计进行阐述,介绍了模具设计和制造过程中的问题.经过生产实践证明,模具结构合理,满足批量生产要求,成型的塑料件达到质量要求.%Foam technology was introduced into producing process of PE wood plastic composite, the influences of foaming agent sorts and content, nucleation agent and foaming process technology on foam quality of PE wood plastic composite were studied Foam properties changes of the composite in different foaming conditions were analyzed. The results showed that PE wood plastics composite with fine and uniform cell and better comprehensive properties was prepared by adopting compound foaming agent, nanoinorganic nucleation agent and expanding gradually method of extrusion faoming technology.
