摘要
通过分析斜齿轮结构特点,常规脱模比较困难,采用螺旋顶杆顶塑料齿轮,依靠螺旋顶杆按螺旋槽轨迹转动,顶着塑料齿轮朝着螺旋槽轨迹同步转动和前进,齿轮顺利从模具内脱模。经过生产实践,模具结构设计合理,使用可靠。
Through the analysis of the inclined gear structure, the conventional stripping helical gear is difficult, adopted spiral push pin to pushing plastic gears, rely on spiral plunger spiral groove track by turns, braved plastic gears turning toward the spiral groove trajectory synchronization, and advance, Gears smoothly from inside mould releasable. Through production practice, the mold structure is reasonable, and use reliable.
