摘　　要：通过对接触器底座进行成型分析,确定了模具设计时待成型底座不同于类似件常规的放置方向、主分型面及成型结构,还介绍了定模型芯预抽芯结构、定模隧道式侧抽芯结构及其工作过程,并对模具设计注意事项进行了说明。模具经生产实践表明:模具工作时稳定可靠,成型的底座满足要求。Based on the forming analysis of contactor base,the placement direction,main parting level,and forming structure of the base to be formed were determined when the mould was designed,which was different from that of similar parts.The pre-core-pulling structure and the tunnel side core-pulling structure of fixed half of mould,and its working process were introduced,the matters needing attention in mould design were explained.The production practice showed that the mould operated stably and reliable,and the formed base met the requirements.
