The company has developed a low-pressure casting method for aluminum alloy wheel preformed shell and aluminum alloy wheel. The present invention provides a preformed shell for an aluminum alloy wheel, which is characterized in that the preformed shell has an inner surface that fits with the bottom of the spoke bottom of an upper die of low pressure casting and an outer surface facing the cavity, and is made of metal . The technical scheme of the present invention has the following advantages: it solves the problem that the metal mold is limited by the draft angle, reduces the thickness of the spoke root of the blank, is conducive to casting, eliminates the original casting defects, and improves the yield; Lightweight wheels.
