The cooling is achieved by absorbing heat through the evaporation of the droplets, thereby assisting the coolant in the cooling coil 21 to cool rapidly and ensuring that the temperature of the coolant during circulation meets the cooling requirements of the molten metal in the casting mold 12.

[0025] Casting frame 1: As the supporting structure of the entire cooling mechanism, it is used to install water tank 2, casting cylinder 11 and other components, providing a stable mounting base for each component.

[0026] Casting cylinder 11: Through telescopic movement, it pushes the casting mold 12 closer together, so that the molten metal can be squeezed into the cavity of the casting mold 12, completing the mold closing action in the casting process.

[0027] Casting mold 12: forms the cavity for casting the vacuum pump body. Molten metal is poured into it and then cooled and solidified to form the pump body.

[0028] Water tank 2: Stores coolant. The cooling coil 21 fixedly installed at its upper end is connected to the casting mold 12. An internal suction pump can draw coolant into the cooling coil 21 to assist in cooling the molten metal in the casting mold 12.

[0036] Atomization nozzle 43: installed in the inner side wall of the atomization box 3, and the position corresponds to the cooling coil 21, receiving the water transported by the water pump 41 through the water guide pipe 42, and spraying the water in the form of mist on the surface of the cooling coil 21, using the heat absorption of droplet evaporation to realize the rapid cooling of the cooling coil 21.

[0037] Working principle:

[0038] When the user performs the casting of the pump body of the vacuum pump, the two casting molds 12 can be pushed close to each other by the casting cylinder 11, and the molten metal can be pushed into the cavities of the two casting molds 12 by the extrusion mechanism. After the molten metal in the cavities of the two casting molds 12 cools down, the casting of the pump body is completed. When the molten metal in the two casting molds 12 is cooled, the suction pump in the water storage tank 2 can be started to suck the cooling liquid into the two cooling coils 21. The two cooling coils 21 are located in the two casting molds 12. When the cooling liquid passes through the casting molds 12, the molten metal in the casting molds 12 can be assisted to cool down. The heat of the molten metal is transferred to the cooling liquid in the cooling coils 21. At this time, the user can quickly cool the cooling liquid in the cooling coils 21 that absorbs heat. The user can start the water pump 41 in the water storage box 4. The water pump 41 can suck the water in the water storage box 4 into the two water guide pipes 42. The water guide pipes 42 spray water mist on the outer sidewall of the cooling coils 21 through the atomizing nozzles 43 to cool the cooling coils 21. The cooling medium is sprayed in the form of mist on the surface of the cooling coils 21 to realize quick cooling by using the heat absorption of droplet evaporation, thereby assisting the cooling liquid in the cooling coils 21 to quickly cool down and ensuring that the temperature of the circulating cooling liquid meets the cooling requirements of the molten metal in the casting molds 12. In the existing casting mold 12, no device is arranged to quickly cool the cooling liquid. The cooling liquid repeatedly circulates in the pipeline to absorb heat, which reduces the subsequent cooling efficiency and affects the cooling efficiency of the molten metal in the casting mold 12. The device is matched with the atomizing nozzles 43 and the water storage box 4. After the cooling liquid in the cooling coils 21 absorbs the heat of the molten metal in the casting molds 12, the atomizing nozzles 43 can spray water mist on the surface of the cooling coils 21 to realize quick cooling by using the heat absorption of droplet evaporation, thereby assisting the cooling liquid in the cooling coils 21 to quickly cool down and ensuring that the temperature of the circulating cooling liquid meets the cooling requirements of the molten metal in the casting molds 12. The water storage box 4 is arranged to collect the condensed water droplets for secondary atomization. The atomizing box 3 is covered with the box cover 31 to avoid water loss as much as possible and avoid waste.

Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, all the embodiments cannot be exhausted.
