摘要
介绍了一种采用弹簧顶销来驱动摆块转动实现内抽芯的三向内抽芯机构,此摆块内抽芯机构巧妙解决了带有内侧凸台或内侧凹陷塑件的脱模问题,模具结构简单,零件易于制造,维修方便,摆块在长时间工作磨损后更换方便。此抽芯机构还适用于需要多个内抽芯的注射模。
It is a difficulty for design of a mould with inward core-pulling mechanism for demoulding of complicated components. A mechanism with inward core-pulling in three directions was developed in which spring knock pin is used to drive the centering block to rotate for the core-pulling action. The structure also applies to injection moulds with more inward core-pulling features.
