针对平衡轴壳体采用普通砂型铸造时,型芯复杂、型腔成形难度大的问题,介绍了平衡轴壳体消失模铸造研制经验,提出了消失模铸造平衡轴壳体的造型工艺、铸造工艺和浇注工艺等主要工艺参数。通过对消失模铸造工艺参数的设计和优化,生产的平衡轴壳体铸件,表面光洁度好、尺寸精度高、废品率较砂型铸造明显降低,经综合性能检验,铸件质量满足用户要求。 Aiming at the problem that the balance shaft shell adopts common sand casting, the core is complex and the forming difficulty of the cavity is very large, the experience of the research on the lost-foam casting of the balance shaft shell is introduced. The modeling technology of the balance shaft shell of the lost- And casting process and other major process parameters. Through the design and optimization of EPC process parameters, the balance shaft shell castings produced have good surface finish and high dimensional accuracy, and the rejection rate is obviously lower than that of sand casting. After the comprehensive performance test, the casting quality meets the requirements of users.
