转子铸铝用离心铸铝法浇注时,其铸铝模的设计方案如图1所示。在实际使用中发现,在切浇口时,体力劳动强度大、时间长、回生浇口多,转子铁心容易冷却,给轴的热套带来了困难。由于原切浇口刀是分段切凿,使短路环内圆形成波段形,很不美观。为此,我们对浇口套和切浇口刀作了改进,见图2及图3。 Rotor cast aluminum centrifugal casting aluminum casting, the design of the aluminum mold shown in Figure 1. In practice, it is found that when the gate is cut, the manual labor intensity is large, the time is longer, the regenerating gate is more, and the rotor core is easy to cool, which brings difficulties to the shaft heat sleeve. As the original cut gate knife is cut into pieces, so that the short-circuit ring into a circle-shaped, very beautiful. For this reason, we made improvements to the sprue bushing and the gate cutter, as shown in Figure 2 and Figure 3.
