摘　　要：分析了带有金属嵌件的塑料件在成型过程中,金属嵌件容易从定位处脱落从而对模具产生磨损的原因。论述了对金属嵌件定位针结构、模具结构设计及嵌件的定位方法等进行改善的措施,结合实际生产情况,确定了采用通过斜销定位嵌件方法。通过试模,达到了预期的模具磨损完全消除的效果,大大地提高了生产效益。In plastic products molding process with metal-insert, reasons for metal-insert tending to fall off setting position and thus cause mould wear were analyzed. Improvement measures on positioning pin structure, mould structure design and position method for metalinsert were analyzed. Combined with the actual production situation, positioning method for metal-insert with taper pin was confirmed. Mould trial shows that mould wear is eliminated completely and the production effectiveness is greatly improved.
