Disclosed in the present application is a low-pressure casting mold for an aluminum wheel. V-shaped grooves are formed in the cavity surface of a side mold, a cavity is formed in the back cavity of the side mold, a cooling duct is arranged in the cavity of the side mold, and a main air pipe is perpendicular to an annular branch; the annular branch is concentric with a wheel casting, and air pipes are 5-10 mm away from the bottom surface of the cavity; the two ends of the annular branch are welded with plugs; air outlet holes are arranged on the annular branch, and the holes are perpendicular to the bottom surface of the cavity; the diameters of the air outlet holes are 3 mm, and the holes are uniformly distributed at intervals of 10-15 mm in the circumferential direction.

Low-pressure casting mold for aluminum wheel

The present disclosure provides a low-pressure cast aluminum wheel mold. The back cavity of a top mold () 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 (), the axial wall thickness of the boss () 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.

Low-pressure cast aluminum wheel mold

A low-pressure casting bottom mold for an aluminum alloy hub is provided. The low-pressure casting bottom mold for the aluminum alloy hub is composed of an upper surface facing a cavity and a lower surface facing a die casting platform, wherein the bottom mold lower surface facing the die casting platform comprises an iron sheet cover, the iron sheet cover is fixed at a position, corresponding to a wheel spoke, of the bottom mold lower surface, and a sealed space is formed between the iron sheet cover and the bottom mold lower surface in a surrounding manner; the iron sheet cover comprises air inlets at one side close to a wheel center and air outlets at one side close to a rim; and the air inlets are connected with air tubes.
