Abstract
The present invention provides an integrated mold for casting of wheels. The integrated mold has an upper mold, integrated side molds and a lower mold, wherein the number of the integrated side molds is four in the circumferential direction of the wheel mold. Thermal deformation circular arc compensation surfaces are formed by processing on an upper and lower one-fourth circular arc part of each integrated side mold, and compensation surfaces are formed by processing on key parts of 45-degree matching surfaces of the adjacent integrated side molds. The integrated side molds can effectively solve the problems such as imprecise matching of the matching surfaces, parting-line flashes of the matching surfaces and adhesion of aluminum caused by thermal deformation of the integrated side molds.
