摘　　要：针对汽车内门把手塑件的结构特点,设计出一模两腔的整体式注射模结构。通过斜导柱滑块二级抽芯机构、斜抽芯和定模斜顶对塑件倒扣进行模具结构优化设计,配合循环水路及顶杆推出设计,热流道转潜伏式的进胶方式避免人工剪浇口,实现塑件的高效自动化注射成型。经过生产实践证明:该模具结构设计合理,工作稳定,生产的塑件质量符合使用要求。In view of the characteristics of structure for the-automobile interior door handle product,the mold is to adopt a two cavity integral structure.The structural optimization design was carried out for many undercuts through external core-pulling,angle core-pulling and fixed mold inclined roof.With the design of cooling system and ejector system,the injection mold runner system adopted hot to cool switching runner and submarine gate,which reduced the cost of manual gate cutting,the efficient automatic injection production could be realized.The production practice proved that the mold structure design was reasonable and the product quality met the use requirements.
