Abstract
The invention relates to a lower die of a die for spinning and casting an aluminum alloy wheel. The lower die is characterized in that the lower die comprises a cushion plate 25, a guide block 26 and a movable block 27 at the wheel cavity position, wherein the cushion plate 25 is fixedly arranged on a bottom die 21 through a bolt 24; the guide block 26 is fixedly arranged on the cushion plate 25 through a bolt 212. As the connection mode of the guide block and the new lower die is optimized, and the cushion plate is additionally arranged, the fit clearance between the guide block and the movable block is adjusted, so that the movable block can be mounted and positioned more easily and expanded smoothly. As the connection mode of the guide block and the new lower die is optimized, and the cushion plate is additionally arranged, the movable block can be effectively expanded, therefore, the problem of the inner diameter inconsistency of the blank is solved, the change on the size of the blank after spinning is avoided, meanwhile, the rigid impact of the die on the wheel is also relieved.
