  • Patent number: 10695828
    Abstract: Disclosed is a continuous casting and continuous forging forming process for an aluminum wheel. The process combines the advantage of low-pressure filling stability of molten aluminum alloy, and utilizes the strengthening effect of extrusion deformation forging of a side mold locking ring and a pressure module to improve the mechanical properties of an aluminum wheel material to close to the forging level. A mold cavity is sealed by means of the side mold locking ring and a center mold locking taper, and the extrusion forging pressure acts on the surface of the aluminum alloy in the closed mold cavity, so that the requirement of equipment for mold closing tonnage is lowered, and the cost of the equipment is far lower than that of forging equipment and equivalent to that of casting equipment.
