摘　　要：根据产品的结构特点,分析了泵盖铸造工艺及成形方案的难点。利用计算机仿真技术,优化了铸造工艺,解决了铸件补缩问题。由于泵盖轮廓小,结构复杂,内部有封闭气道,常规造型方法无法成形,通过在铸件上开设工艺孔及应用3D打印技术,解决了其铸造成形问题。铸件的实际检测结果表明,各项指标均符合要求。According to the structural characteristics of the casting,the difficulties of the casting process and the molding scheme were analyzed.The computer simulation was used to optimize the casting process and the problem of casting shrinkage was solved.Since the outline size of the pump cover is relatively small,its structure is complex,and there is a closed air passage inside the casting,the conventional molding scheme cannot be used to form the casting.This problem is solved by opening the craft hole on the casting and applying the 3D printing technology.The actual test results of the casting show that all indexes meet the requirements.
