摘要
塑料斜齿轮注射模常规脱模比较困难,通过采用顶管顶塑料齿轮,依靠单向推力球轴承,齿轮螺旋面作用于顶管转动,顶管推着齿轮顺利从模具内脱模。经过生产实践,该模具结构设计合理,使用可靠。
Through the analysis of the conventional stripping helical gear is difficult, using the plastic pipe jacking top gear, rely on single direction thrust ball bearings, Gear spiral face in the role of pipe jacking rotation, Top tube pushes gear in the mould smoothly from stripping. Through production practice, the mold structure design is reasonable, and use reliable.
