Technical Problem

[0003]在电池包的生产制造过程中,常采用注塑成型的方式生产其主体外壳结构,在注塑生产过程中,对于电池包主体带有复杂几何结构,需要使用镶针来配合塑造,而在合模、脱模过程中,容易因操作顺序不合理,导致镶针受到碰撞而受力折弯、损坏,这会导致产品不良率升高,且如果频繁停机更换镶针,则严重制约了生产效率

Benefits of technology

本实用新型通过一次镶件脱模机构先驱动销与锁扣的配合带动镶针从塑件中拔出,再通过二次行位脱模机构带动行位整体远离模芯,采用分步式依次顺序进行脱模、合模操作,从而起到保护镶针的作用,避免镶针与模具中的结构在运动过程中发生碰撞,导致镶针损坏。
