The invention discloses a crystallization pressurization method for low-pressure casting molding of an aluminum alloy wheel metal mold. The method continues a traditional aluminum alloy wheel low-pressure casting process in phases of liquid rising and mold filling; and the liquid rising pressure and the mold filling pressure are controlled within 18-21 kPa and 30-35 kPa. The crystallization pressurization is divided into two phases according to the solidification time of inner and outer rims after mold filling; in the first phase, the mold filling phase is finished to completion of solidification of the inner and outer rims, and the crystallization pressurization pressure is increased to 80-150 kPa; and in the second phase, after the solidification of the inner and outer rims is finished, the crystallization pressurization pressure is quickly increased to 160-1000 kPa, and the pressurization speed is 10-40 kPa/s. Then, a pressure keeping phase is switched to; rims, rim and spoke transition parts and wheel centers are solidified in sequence; a casting is cooled; and the pressure is relieved. The method prominently improves the solidification feeding effect and the casting mechanical performance, prevents such defects as molten aluminum splashing and casting flanges and burrs, and prominently reduces the requirements on the mold structure and the casting mold clamping force.
