摘　　要：铸件带有深腔,开模时铸件容易包紧在定模型芯上,并最终留在定模,给取件带来困难,模具设计时采用了具有延时作用的特殊斜销,消除了铸件对定模型芯的包紧力,从而使铸件留在动模。模具使用情况良好,所生产的零件能满足精度和表面粗糙度的要求。The deep-cavity casting part may wrap the cores in the fixed haft during the forming process and make it difficult to strip. The special angle pins with delay effect are applied in the die for eliminating the wrapping force and then the casting part was re mained in the moving half. The casting part has side hole which needs the application of curved pin in the moving half of the die for core-pulling.
