The low-pressure casting die for aluminum alloy wheel is developed by the company. The low-pressure casting die consists of a top die, a side die and a bottom die. The top die, a side die and a bottom die are combined to form a casting cavity for aluminum alloy wheel, the utility model is characterized in that the top die comprises a ring groove at the upper part of the inner wheel flange and a parting surface ring groove on the clamping surface of the top die and the side die. The low-pressure casting die for the aluminum alloy wheel of the utility model has simple structure. Through improving the existing die structure, the defects of shrinkage porosity, air hole and oxide slag inclusion can be effectively improved; At the same time, the cooling speed of wheel flange is accelerated, the inner grain is further refined, the structure is more uniform, the casting quality is improved, and the rate of finished wheel is greatly improved.
