摘　　要：采用定模内和动模内镶件互换结构设计,实现了同一套模具可生产某汽车座椅侧护板(有按钮孔和无按钮孔)2种不同结构的塑件,提升了模具的使用价值,降低了产品研发的成本,并通过设计便捷式模内镶件互换结构,极大地减少了拆模、装模的时间和人工成本。异型的斜顶抽芯机构与直顶顶出机构相配合,解决了常规斜顶抽芯机构在设计位置不足的情况下完成塑件倒扣的正常脱模。An interchanging structure design was adopted for the plastic parts of a car seat side guard plate(with and with⁃out a button hole)mold structure with a fixed mold and a moving mold.Such a design solved the problem that the same mold could produce two types of plastic parts with different structures,improve the use value of the mold,and reduce the cost of product research and development for products.Through the design of convenient interchanging structure of a mold insert,the removal of mold,mold installation time,and labor costs were greatly reduced.The abnormal⁃shaped in⁃clined top core⁃pulling mechanism and the straight top core⁃pulling mechanism could cooperate to help the conventional inclined top core⁃pulling mechanism to complete the normal demolding of the plastic parts when the design position was insufficient.

关 键 词：镶件互换结构 异型 斜顶抽芯机构 直顶顶出机构
