[0038] The specific application of the second embodiment is: pouring the molten magnesium-aluminum alloy liquid between the first mold 303 and the second mold 306 through the casting pipe 327, so that the molten magnesium-aluminum alloy liquid is cooled and cast between the first mold 303 and the second mold 306, and in the process of casting the vehicle parts, the liquid pumping pump 331 is started, so that the cooling liquid stored in the water tank 301 enters the cooling cavity 304 through the liquid outlet pipe 332, the flow hose, the liquid inlet pipe 330 in turn, and finally enters the water tank 301 after cooling is completed (in the process of pumping the cooling liquid in the water tank 301, the water tank 301 is divided into two areas by the heat insulation plate 328, wherein the area connected with the liquid pumping end of the liquid pumping pump 331 is the cooling water that is not subjected to flow cooling, the cooling water that is not subjected to flow cooling in this area is added mainly through the communication pipe connected therewith, the communication pipe is arranged on the outer side of the water tank 301 near the liquid pumping pump 331, and the surface of the communication pipe is provided with an electromagnetic valve for controlling the addition of liquid, in addition, the area connected with the liquid outlet pipe 338 is the area for storing the cooled cooling water, and the circulation pipe 329 arranged in communication therewith and the electromagnetic valve arranged on the side surface of the circulation pipe 329 are used to control the discharge of the cooled cooling water), so as to cool the cast vehicle parts during the casting process, and facilitate the demolding operation in the later stage; The cooling water entering the cooling cavity 304 will be temporarily stored in the cooling cavity 304 in the initial stage of cooling the vehicle parts in the casting process. In the later stage, as the water level of the cooling water in the cooling cavity 304 rises, the rising water level gradually approaches the surface of the high-temperature-resistant buoyancy balls 318. At this time, the water level of the cooling water continues to rise, and the high-temperature-resistant buoyancy balls 318 begin to generate a certain buoyancy in the cooling cavity 304 (the buoyancy of the high-temperature-resistant buoyancy balls 318 in the cooling water is greater than the elastic force of the buffer spring 340, and during the floating process, the buffer spring 340 is compressed, facilitating the subsequent resetting of the upward moving frame 333). The upward moving frame 333 gradually rises, causing the liquid outlet pipe 338 slidingly fitted in the vertical pipe 337 to move upward synchronously, causing the liquid leakage hole 343 provided on the side surface of the liquid outlet pipe 338 to gradually leak out of the vertical pipe 337 and gradually be located in the cooling cavity 304, so as to timely drain the cooling water cooled for a period of time and continuously cool the water. When the cooling liquid stored in the water storage tank 301 enters the cooling cavity 304 through the liquid outlet pipe 332, the flow-through hose, and the liquid inlet pipe 330 in sequence, the sliding ball 341 provided on the opposite side surfaces of the upward moving frame 333 will slide in the two symmetrically arranged threaded grooves 336, respectively, so as to drive the two rotating shafts 334 and the plurality of stirring blades 335 fixed on the side surfaces of the two rotating shafts 334 to rotate reversely in the cooling cavity 304 synchronously, so as to increase the turbulent effect of the cooling water in the cooling cavity 304. The cooling water can more effectively exchange heat before being drained, so as to accelerate the heat exchange between the cooling water and the heat in the casting process through the flow of the cooling water itself, and improve the demolding efficiency in the whole process.
