前言： 为了保证一种既有斜齿轮又有直齿轮零件在注塑成形后能顺利脱模，给出了一套一模两位，点浇口进料， 旋转脱模，胶套式二次分型的双分型面注射模的设计。
To make sure that a plastic part with helical gear and spur gear can be demoulded successfully, an injection mould is designed with double parting faces, point gate feeding and rotating demould.
选择中心浇口可以降低注射压力，但是采用测面浇口的注射坯比采用中心浇口的注射坯件温度和压力分布都要均匀。
But the green parts have a more even distribution of temperature and pressure by lateral gate than by central gate.
通过对主体压铸件的结构工艺性分析，确定了模具结构设计方案，介绍了台阶分型面选择、立式缝隙浇口浇注系统设计、预复位推出机构设计和镶块镶拼结构设计。
Througn designing three axial slots in internal threaded portion and optimizing nib structure, a design was made on the injection mould with a two-step ejecting mechanism with non-rotating.
