The utility model is suitable for the casting technology field of motor shell, and provides a casting system for motor traction motor shell, which comprises an inner sand core made of furan resin sand, a straight runner for the inner sand core, a plurality of cross runners under the straight runner and connected with the bottom of the straight runner, a filter net fixed at the bottom of the straight runner and located in the cross runner, and a filter net surrounding the inner sand core and the motor shell. The shape matching cavity is provided with an inner gate connected with the cavity at one end of each runner. The surface of the motor shell is surrounded by a number of radiators distributed along the length direction of the motor shell. The cavity is vertically arranged and used for forming the motor shell. One end of the runner is connected with the bottom end of the cavity; and a number of risers are connected with the top of the cavity. The pouring system of the shell of the traction motor of the electric locomotive provided by the utility model filters the dross in the aluminium liquid flowing into the transverse runner through a filter screen, so that the slag content of the motor shell is low, and the appearance and performance of the motor shell are good.

一种动车牵引电机壳体浇注系统
本技术属于电机壳体铸造
,尤其涉及一种动车牵引电机壳体浇注系统。
技术介绍
铸造是将金属熔炼成符合一定要求的液体并浇进铸型里,经冷却凝固、清整处理后得到有预定形状、尺寸和性能的铸件的工艺过程。壳体铸造部件在浇筑成型过程中,铸件容易出现含渣量高的现象,使得加工产品的不合格率较高。尤其对于动车动力系统所使用的电机属于大型电机系列,对外壳的性能要求较高。现有技术中,动车牵引电机壳体在铸造过程中,浇注系统中通常没有设置用于过滤铝液中浮渣的过滤装置,使成型得到的电机壳体含渣量高,从而影响电机壳体的外观和性能。
