摘　　要：在综合实验过程中,针对凸模与推件板存在方位差不能装合的问题,让学生自行分析,找出电火花线切割时,凸模对称中心线偏转螺孔连线、基准不一致和装夹误差的问题所在,提出了解决对策。依据对策所加工的模具零件消除了装配上的干涉现象,零件间运动自如,注塑件壁厚均匀,较好地完成了实验教学任务。In the comprehensive experiment,there was a problem that the punch and the push board could not be installed for the difference in orientation. Students can analyze and identify the causes by themselves. There were the punch symmetrical centerline deflecting holes connection,benchmarks inconsistencies and clamping error in the WEDM process. They proposed some countermeasures.Based on the measures,they smoothly completed the experimental teaching tasks. They eliminated the interference between mold parts during the assembly process. The parts moved freely and the wall thickness of injection molded parts was uniform.
