一种无痕推出饰罩注射模设计

Design of Injection Mold for the Traceless Ejection Decorative Cover

分析了一种塑钢窗用五金铰链饰罩结构的工艺特点,重点分析了饰罩塑件注射模无痕推出结构的设计和工作过程,该模具独辟蹊径采用二次开模与二次推出相结合的结构,彻底解决了传统模具手工取件或气吹取件方式。该模具经过批量生产实践证明,生产过程中模具开合顺畅,开模后塑件自动脱落,不需要人工看护,实现了无痕推出,实现了全自动生产,提高了生产效率和安全系数,符合设计要求,适用于大批量生产。

This article briefly analyzes the process characteristics of a hardware hinge decorative cover structure for plastic steel windows,with a focus on the design process and working principle of the traceless ejection structure of the injection mold for decorative cover plastic parts.The mold adopts a unique combination of secondary mold opening and secondary ejection structure,completely solving the outdated method of manual or air blown parts extraction in traditional molds.The mass production practice of the mold has proved that the mold can be opened and closed smoothly during the production process,and the plastic products can fall off automatically after the mold is opened,which does not require manual care.The mold can be pushed out without trace,and it can achieve full automatic production,improve production efficiency and factor of safety,meet the design requirements,and is suitable for mass production.
