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.
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。
The transmission part is an involute gear, and the working part can adopt different working faces, such as a cylinder excircle face, a circular arc tooth or an involutes tooth gear top cavetto.
传动部分是渐开线齿轮，工作部分可采用不同的工作面，如圆柱外圆面或圆弧形齿或渐开线齿轮齿顶修圆。
