company news about What are the advantages of gravity casting molds for aluminum alloy wheels and their casting methods?

The company has developed an aluminum alloy wheel gravity casting mold and its casting method. The aluminum alloy wheel gravity casting mold includes a cooling device, a top mold, a side mold, a bottom mold and a mold cavity formed by the top mold, the side mold and the bottom mold. The bottom mold is provided with a diverter cone, and the aluminum alloy wheel gravity casting mold also includes a thermos cup that communicates with the mold cavity and can store aluminum liquid, so that the aluminum liquid stored in the thermos cup can be continuously injected into the mold mold. The pressurizing device in the cavity is a blocking device that can prevent the molten aluminum stored in the thermos cup from flowing into the mold cavity under the action of gravity. The thermos cup is set on the top mold, and the pressurizing device is installed in the gravity casting machine. On the frame of the aluminum alloy wheel, the intercepting device is installed on the bottom mold or on the frame of the gravity casting machine; the casting method of the gravity casting mold of the aluminum alloy wheel includes injecting aluminum liquid, pressurizing, continuous casting, filling, replenishing shrinkage and crystallization. The aluminum alloy wheel cast by the invention has the advantages of less risers, high weight yield and good quality stability.
