摘要
The present application relates to a low-pressure casting multi-sprue process and device for an aluminum alloy wheel. A multi-sprue casting method is adopted, and a plurality of sprues are arranged at the end of the inner flange of a wheel, so that molten aluminum enters at the inner flange first, then enters from a center sprue after a mold cavity at the rim is full of the molten aluminum. The mold assembly is pressurized and cooled after the mold cavity is full of the molten aluminum. During cooling, starting from the outer flange of the wheel filled with the molten aluminum last, side mold ring water coolers are started.
