摘要： 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.

摘要： The invention discloses an improved wheel alignment device which comprises a rack, a cylinder, a servo motor, a hollow shaft and the like. When the improved wheel alignment device is used, a stopper on a roller table centers a wheel, air enters at the lower end of a large piston and causes a long cylinder rod, a flange end cover, an expanding sleeve and the like to rise; the flange end cover is in contact with a wheel flange plate, and after the expanding sleeve is in contact with a central hole, air enters at the upper end of a small piston of a small cylinder, a short cylinder rod pulls an expanding core downwards, and the expanding sleeve clamps the central hole of the wheel; the servo motor causes the hollow shaft and the wheel to rotate by a belt pulley I and a belt pulley II, and the hollow shaft and the wheel stop rotating after a sensor finds the position of a valve hole of the wheel; at the moment, lifting cylinders cause a supporting plate to rise to a certain height through guide pillars, and a large cylinder causes the wheel to descend and the lower end surface of the wheel to fall above the supporting plate. The improved wheel alignment device can realize the alignment function before the automatic machining of wheel finish turning in use, and when the wheels with different wheel widths and different offset distances are automatically produced, programs do not need to be switched.

摘要： The invention provides a split-type mold for wheel casting, the mold having an upper die, a split-type water-cooling side die and a lower die, and the split-type water-cooling side die is divided into four pieces along a circumferential direction of the wheel mold. A thermal deformation arc compensation surface is machined on ¼ arc portion of each split-type water-cooling lower side die, and a compensation surface is machined on key portions of 45-degree matching surfaces of adjacent split-type water-cooling upper side dies. The side die can effectively solve the problems such as untight matching between the matching surfaces, flashes of the matching surfaces and aluminum sticking and the like due to the thermal deformation and non-homogeneous expansion and shrinkage of the two portions of the split-type water-cooling side die.
