Abstract
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.
