Mold air and water combined cooling system and low-pressure wheel hub mold with same

Abstract

The invention discloses a mold air and water combined cooling system. The mold air and water combined cooling system comprises an external air pressure source machine, a first pressure gauge, a first flow meter, a first pipe and a main pipe. The external air pressure source machine is connected to one end of the main pipe through the first pipe, the other end of the main pipe comprises at least two or more diversion pipes, the first pipe is provided with the first flow meter, and the diversion pipes are connected to mold hot junction cooling terminals. The mold air and water combined cooling system further comprises an external circulating cooling water machine. The external circulating cooling water machine is connected to a second pipe, the second pipe is connected to the first pipe in parallel and then is connected to the main pipe, a second pressure gauge, and a second solenoid control valve and a second flow meter are arranged on the second pipe sequentially. The first pipe is also provided with a first solenoid control valve. The diversion pipes are in the same number with the mold hot junction cooling terminals and all provided with solenoid control valves. The mold air and water combined cooling system can quickly cool and solidify mold hot junction portions through matched air cooling and water cooling. The invention also discloses a low-pressure wheel hub mold.

Description

technical field [0001] The invention relates to the technical field of automobile hub molds, in particular to an air-water mixing cooling system for cooling molds and a low-pressure hub mold with the cooling system. Background technique [0002] The air cooling structure of the existing automobile wheel hub mold uses compressed air with a pressure of 4-6kgf to act on the cooling terminal of the mold to take away the heat of the automobile wheel hub mold, so as to achieve the purpose of reducing the mold temperature. However, the cooling rate of this cooling method is slow, which will lead to the extension of the mold opening time, thereby affecting the production efficiency of the product and the mechanical properties of the product material. [0003] In the prior art, there is a method of changing the compressed air to mixed and atomized water vapor to cool the cooling terminal. Although the cooling effect of water vapor is better than that of compressed air, the water vapo...

[0003] In the prior art, there is a method of changing the compressed air to mixed and atomized water vapor to cool the cooling terminal. Although the cooling effect of water vapor is better than that of compressed air, the water vapor remaining in the channel will cause rust on the one hand, and on the other hand On the one hand, the residual position will also lead to uneven cooling effect
