Problems solved by technology

The casting method through natural cooling not only has low production efficiency, but also it is difficult to control the solidification and molding sequence of the casting billet, which makes the product prone to defects and reduces the qualified rate of casting products. The pass rate is of great significance

Embodiment Construction

[0018] Such as figure 1 with figure 2 As shown, the cooling system of the automobile wheel hub mold includes a working fluid circulation system, a cooling water circulation and a direct air cooling system.

[0019] The working fluid circulation system consists of a hub mold 1, a compressor 2, a liquid storage tank 4, a working fluid circulation pump 5, an expansion valve 6, an evaporation channel 10, a water-cooled condenser 7 or an air-cooled condenser 3 and pipelines. The outlet of the evaporation channel 10 in the hub mold 1 is connected to the inlet of the compressor 2 through a pipe, and the outlet of the compressor 2 is divided into two ways: one way is connected to the hot fluid side inlet of the water-cooled condenser 7 through the pipe, and the hot fluid side outlet of the water-cooled condenser 7 Connected to the inlet of the liquid storage tank 4 through a pipeline; one way is connected to the hot fluid side inlet of the air-cooled condenser 3 through a pipeline, and ...

Abstract

The invention provides an automobile hub die cooling system, and belongs to the technical field of mechanisms. The automobile hub die cooling system solves the problem of low stability in the prior art. The cooling system comprises a working medium circulating system and a cooling water circulating system and direct air cooling system, wherein the working medium circulating system comprises a hubdie, a compressor, a liquid storing tank, a working medium circulating pump, an expansion valve, an evaporating flowing channel, a water cooling condenser or an air cooling condenser and a pipeline; and the cooling water circulating system comprises a water cooling condenser, a cooling tower and a circulating water pump. According to the system, pure organic working mediums such as HFCs, HCs, HEFs, PFCs, CF3I and HFO1234y or water is used as a circulating working medium the working medium circulating system; a water cooling or direct air cooling manner can be carried out on the cold end; and the two cooling manners can be independently set or combined. The system is high in stability.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to an automobile wheel hub mold cooling system. Background technique [0002] Automobile wheel manufacturing technology can be divided into casting and forging. Casting production involves letting molten aluminum enter the mold, filling the mold with the gravity of the molten aluminum or continuously pressurizing it with high-pressure gas until the molten aluminum is cooled and solidified in the mold. As for forging production, the wheel blank is formed by tapping, pressing, forging and other means. However, the cost of the forging press required for forging aluminum alloy wheel blanks is too high, so casting is now a more commonly used production process. In the casting production, during the solidification process of molten aluminum from liquid to solid, the phenomenon of volume reduction is called shrinkage. Shrinkage is the physical property of aluminum alloy itself, and it is also c...
