Abstract

The invention provides an aluminum alloy wheel hub forging die, which belongs to the technical field of forging dies. It solves the technical problems such as insufficient filling of the wheel hub due to poor exhaust of the existing forging die. The invention comprises a lower mold base, an upper mold core, a lower template, a lower mold core, and a lower ejector rod. A limit plate is fixed on the lower ejector rod, an exhaust channel is arranged at the lower template, and the lower mold core includes a The connected forming part and the connecting part connected to the lower end of the forming part and fixedly connected with the lower template, the diameter of the forming part is smaller than the diameter of the connecting part, and the lower pusher is fixedly connected to the limit plate, and the lower pusher has a sleeve set on the An annular pusher plate on the connecting part and capable of pushing the wheel hub together with the lower push rod. An exhaust ring groove connecting the cavity and the exhaust channel is formed between the outer wall of the annular pusher plate and the inner wall of the lower mold seat. The exhaust ring The sectional width of the groove is smaller than the sectional width of the exhaust passage. The invention can effectively prevent the blockage of the exhaust structure, and ensure the smooth exhaust of the forging die and the full filling of the wheel hub.

Description

technical field [0001] The invention belongs to the technical field of forging dies, in particular to an aluminum alloy wheel hub forging die. Background technique [0002] Forged aluminum alloy wheels have the advantages of light weight, excellent mechanical properties, and high safety, and have become the mainstream manufacturing process of automobile wheels. The forging die is one of the important tools for forging aluminum alloy wheels. It includes an upper die and a lower die. The upper die is mainly composed of an upper die plate, an upper die base and an upper die core. The lower mold plate at the lower end of the mold base, the lower mold core set in the lower mold base, and the lower push rod that penetrates the lower mold plate and the lower mold core and is used to push the wheel hub, among which the upper mold core and the lower mold core And a cavity is formed between the inner walls of the lower mold base. When forging the wheel hub, first place the aluminum ...
