斜滑块内抽芯塑件的注射模具设计

Design of Injection Mould for the Plastic Parts with Sides Core-Pulling

分析了零件的成型工艺特点,设计了一模两型腔、圆周七瓣斜滑块内抽芯的注射模结构,巧妙地把斜销抽芯结构分解成斜滑块内抽芯结构,有效地克服了由于空间狭小、结构工艺性差造成的斜销抽芯困难,还使模具各零件的制造更方便、更快捷。通过试生产证明,该模具使用效果良好。

The forming process of plastic parts is analyzed, the injection mold mechanism of one mold with tow cavities and seven sides core-pulling is designed, finger cam core-pulling structure are subtly broken down angled-lift splits core-pulling structure which effectively overcomes the difficulties of inner core-pulling caused by small spaces and poor structural process, the mold of parts is made more convenient and faster. the testing manufacture shows the design is effective.
