The company has developed a gravity casting die for aluminum alloy wheel and its casting method. The gravity casting die for aluminum alloy wheel comprises a cooling device, a top die, a side die, a bottom die and a mold cavity formed by a top die, a side die and a bottom die, a flow dividing cone is arranged on the bottom mould, the gravity casting mould for the aluminum alloy wheel also comprises an insulating cup which is communicated with the mould cavity and can store the aluminum liquid, a pressurizing device which can continuously inject the aluminum liquid stored in the insulating cup into the mould cavity, and a blocking device which can prevent the aluminum liquid stored in the insulating cup from flowing into the mould cavity under the action of gravity, the Insulating Cup is arranged on the top mould, the pressure device is arranged on the frame of the gravity casting machine, and the blocking device is arranged on the bottom mould or on the frame of the gravity casting machine; The casting method of gravity casting die for aluminum alloy wheel includes injecting aluminum liquid, pressurizing, continuous pouring, filling, feeding and crystallization solidification. The cast aluminum alloy wheel has the advantages of less riser, high weight yield and good quality stability.
