摘要
分析了点浇口注射模成型薄壁制品的工艺特点 ,介绍了注射模结构、点浇口设计方案和模具工作过程 ,模具采用3次分型、多点浇口自动切断及双锥形滑块侧向抽芯、推管推出的结构形式 ,有效地解决了点浇口注射模成型薄壁制品的常见缺陷 ,实现了大批量全自动生产。
The technological characteristics of the injection mould with pin-point gate for forming thin-wall plastic parts are analyzed.The mould structure,design of the pin-point gate and working process of the mould are introduced.The structure forms such as3-time parting,automatic shutˉting of multiple pin-point gates,double-tapered-slide-block side core-pulling and ejecting by ejector sleeve have been adopted to effectively prevent the usual defects occurred in forming thin-wall parts by injection moulds with pin-point gates.Automatic mass production has been realized.
