Sand-lined Metal Mould Casting Application on end Cap of Traction Motor for Motor Base Castings of Rail Transit
The structural characteristics and technical requirements of the motor frame castings were analyzed.One of the motor frame castings was selected as an example,the semi-closed casting system was determined according to the characteristics of the iron mold sand coating process,and the key points of the iron mold sand coating process design and sand core design of the casting were analyzed.The iron mold sand coating casting process plan was verified and optimized by using finite element software.The process scheme of the motor frame casting is feasible,the iron sand ratio is 1:6,the process yield is 90.8%,and the product qualification rate is 95%.The economic efficiency is remarkable,and mass production has been achieved.
