Abstract: A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.

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.
