If a flowmeter 83 and solenoid valve 84.
When the wheel rim of wheel hub will just cool down, the intermittent opening and closing of solenoid valve 4 is controlled by PLC pulse-control system, is allowed net
It is spraying towards hub mold intermittence by nozzle 85 to change water, water mist is allowed uniformly to be attached to hub mold surface, recycles repeatedly interval
Property it is spraying, until wheel hub forming.
It should be noted that it is at high cost therefore most important to the effective rate of utilization of water to water progress purified treatment, existing
In some cooling technologies, the high temperature of die surface can make the vaporization of absorb heat rapidly of the cooling water of contact generate water vapour, water steaming
Vapour gas is covered in die surface and forms one layer of gas-barrier layer, and gas-barrier layer barrier cooling water makes it flow away to two sides, causes
The cooling water of injection later can not contact die surface and absorb heat, reduce the cooling effect of mold, and also waste
Many cooling waters.Therefore the present invention is intermittent spraying using the control of solenoid valve 84 nozzle 85, provides for the barrier layer of die surface
Sufficient Divergent Time, is further continued for misting cooling, keeps cooling effect more obvious, moreover it is possible to the waste for reducing cooling water resources, from
And reduce casting cost.According to hub mold temperature conditions in this specific embodiment, designing intermittent is by spraying 2 seconds by spraying, is stopped
Only 3 seconds, it can be achieved that the purified water on hub mold surface sufficiently evaporates.
Above-described embodiment and schema and non-limiting product form and style of the invention, any technical field it is common
The appropriate changes or modifications that technical staff does it all should be regarded as not departing from patent category of the invention.
