Abstract
Disclosed is an aluminum alloy wheel squeeze casting process and an aluminum alloy wheel squeeze casting device. Molten aluminum is injected into a mold cavity from the bottom by adopting a U-shaped pipe, so that the filling is stable and the quality problem of the pore defect of a squeeze cast rim is solved; the squeeze deformation effect of the rim is strengthened using a mold locking ring; and through a secondary pressurization process for the center of the aluminum wheel, the internal dendritic spacing of the aluminum wheel casting is reduced, the yield strength and the elongation in the material mechanical properties of the casting are improved, and a necessary technical foundation is provided for overall weight reduction of the aluminum wheel.
