摘　　要：介绍了一种由于结构限制必须使用分层抽芯,并且存在需要从侧抽部分再抽芯的一种模具结构。根据这些结构限制,设计了一种基于二次开模的双层抽芯结构,并对模具上使用的插销式锁模器进行了改进。此结构实现了此类型塑件多方向抽芯动作的完成及顺利顶出塑件,实现了自动化生产。A mould structure which uses the two-stage core-pulling mechanism in this paper. In this mould, a secondary core-pulling structure is adopted on the basis of the primary side core-pulling. Due to the structure constraint of the mould, a double core-pulling structure based on two-stage mould parting is proposed, and the clamping device with plug-pin is also optimized. Using this mould structure, the multi-directional core-pulling action and the ejecting action can be completed stably. This mould also realizes the automatic production.
