【Abstract】 In the paper, the structural characteristics and technical requirements of end cap casting for the YQ-625 type traction motor were introduced. The sand-lined metal mould casting process for the end cap casting was analyzed. Furthermore, by adopting the finite element software Pro CAST to optimize the process scheme, the optimal sand-lined metal mould casting process for the end cap casting was determined. The production practice shows that the optimal process scheme of the end cap casting is feasible, and the batch production of the casting has been achieved.更多还原
