After the water in the drain pipe 430 enters the cooling chamber 412, the blower 510 is started, the blower 510 conveys air into the blower pipe 520, the electromagnet 532 drives the magnet 533 and the non-return pipe 531 to approach the electromagnet 532, then the air inlet hole is communicated with the air blowing hole 521, the air enters the cooling chamber 412 to disturb the water, and meanwhile, the contact area of the water and the air is increased, so that heat in the water is rapidly dissipated; when the water level is higher than the overflow hole 441, the water flow pushes the check plate 451 to rotate, the check plate 451 opens the overflow hole 441, and the water flow enters the water storage chamber 411 through the overflow hole 441 and then cools the fixed mold 310 and the sliding mold 320 through the cooling pipe 420.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
