The invention discloses a
casting process method of an integrated
water cooling circulation motor casing. The method includes the steps that a, a
water channel sand core is manufactured first; b, the
water channel sand core is placed in a die; c, then, die assembling is conducted on the die through
hydraulic pressure stations on the periphery, and the
water channel sand core is fixed through set compressing points; d, afterwards, pressure is applied to molten aluminum in a
crucible through an air pressure filling
control system of a low
pressure casting machine; e, the height of the molten aluminum is increased slowly through a liquid rising tube, air pressure is increased when the molten aluminum arrives at the die bottom of the die, and accordingly an entire cavity is filled with the molten aluminum at the speed of 0.9-1.3 m / s; f, pressurization is conducted continuously, and the motor casing is condensed and solidified under certain pressure; g, the cast motor casing is taken out from the cavity of the die, and after complete cooling, the water channel sand core is removed through sand burning, heat treatment and sand shaking; h, a feeder head and burrs are removed ultimately. By the adoption of the
casting process method, the production efficiency and the percent of pass can be improved, the labor intensity of workers is lowered, and the production cost is lowered.
