Abstract: The present disclosure provides a low-pressure cast aluminum wheel mold. The back cavity of a top mold (1) is divided into three parts: the back cavity in a rim area is open, and the wall thickness of the top mold is progressively increased by 15-25 mm from bottom to top; the back cavity in a spoke area is machined in a profile-followed manner, and the top mold has an equal wall thickness of 20-30 mm; at each R angle position where the rim is connected with a spoke, the top mold is provided with a boss (11), the axial wall thickness of the boss (11) is 40-60 mm, and the radial wall thickness is 30-50 mm. A temperature gradient beneficial to progressive solidification of a casting is constructed; by designing an annular water cooling structure at the R angle where the rim is connected with the spoke, quick cooling on the hot spot is specifically realized, the cooling capability is stronger, the cooling range is more exact, bad influence on the adjacent thin-wall part is not produced, and smooth feeding of molten aluminum is ensured.

Abstract: Disclosed are a wheel lightweight machining fixture and method. The fixture comprises a rotating chuck, an electric cylinder, a guide rail, a slide block, a first linear motor, radial positioning blocks and the like. When the electric cylinder drives the slide block to move along the guide rail, the position where an first ultrasonic thickness measuring sensor is in contact with a wheel spoke can be adjusted, so that the spoke thicknesses at different positions can be detected. Through motion of the turrets, an second ultrasonic thickness measuring sensor can contact the outer rim of the wheel and detect the rim wall thickness. By integrating a measurement feedback system into the manufacturing process, the disclosure provides a fixture and a method for minimum entity machining of the rim wall thickness and the spoke thickness of a wheel during the first stage turning process, thereby realizing lightweight manufacturing of the wheel.

The water cooled mold is provided with first-type water cooling channels with high heat exchange efficiency and second-type water cooling channels with low heat exchange efficiency. The first-type water cooling channels are concave grooves through which cooling water flows, and a cooling surface of the mold is in contact with open surfaces of the concave grooves. The second-type water cooling channels are grooves with stainless steel pipes, and the stainless steel pipes are in contact with the cooling surface of the mold. The second-type water cooling channels are installed on mold portions corresponding to wheel window positions of a cavity, and the first-type water cooling channels are installed on mold portions corresponding to spokes, flanges and rims of the cavity. The water cooled mold of the present invention is capable of accurately controlling a direction and a range of cooling within a three-dimensional space; the use of a thermal insulating groove is omitted so that the mold can be manufactured more simply and the service life of the mold can be prolonged; the cooling efficiency is high and resources are saved; and the whole device is simple to manufacture and low in cost.

Abstract: 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.

Abstract: The present invention provides an integrated mould for casting of wheels. The integrated mould has an upper mould, integrated side moulds and a lower mould, wherein the number of the integrated side moulds is four in the circumferential direction of the wheel mould. Thermal deformation circular arc compensation surfaces are formed by processing on an upper and lower one-fourth circular arc part of each integrated side mould, and compensation surfaces are formed by processing on key parts of 45-degree matching surfaces of the adjacent integrated side moulds. The integrated side moulds 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 moulds.
