Further, the small holes on the preferable annular water channel are obliquely upward holes, so that water can be discharged more smoothly.

Furthermore, the preferable top die body is in clearance fit with the water-cooling insert, so that the assembly is convenient.

Furthermore, after the assembly is completed, a certain gap A is formed between the annular water channel of the water inlet assembly and the cooling inclined plane of the top die, and the value range of A is 3-8mm, so that the cooling water can smoothly flow out.

When the cooling device works, water enters the annular water channel from the water inlet pipe, then enters the water cavity formed by the cooling inclined plane of the top die body and the cavity inclined plane of the water cooling insert through the small holes, and finally is discharged out of the die through the water outlet pipe, so that the cooling effect is achieved.

Compared with the prior art, the utility model has the beneficial effects that: the utility model is that

The cooling of the wheel hub rim is realized, so that the cooling efficiency of the aluminum alloy wheel hub rim is improved, the yield is greatly increased, and the energy loss is reduced.
