Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy casting, in particular to a cooling device for magnesium alloy casting. Background Art

[0002] Aluminum-magnesium alloy generally refers to aluminum alloy with magnesium as the main added element. It has the advantages of high strength, low density, and good heat dissipation. It is widely used in electronics, automobiles, aerospace and other fields.

[0003] For example, the Chinese patent: CN215544780U discloses the following technical solution: A cooling device for semi-continuous casting of magnesium alloy, including a cold water tank, the top of which is open and arranged below the molded part, the molded part is a cooling box, a stirring assembly is arranged inside the cooling box, a molding groove is arranged on the upper surface of the cooling box, a spray assembly is arranged above the molding groove, and the cold water tank is also connected to the cooling box through a water inlet pipe and a water outlet pipe. The structure is simple and reasonable, and the operation is convenient. The metal in the molding groove is quickly and effectively cooled up and down and left and right through the cooperation between the spray assembly and the cooling box. The spray head can be adjusted up and down, so that the cooling is more efficient and the splashing range after the cold water contacts the molding groove is reduced; the setting of the U-shaped paddle can fully stir and mix the cold water in the cooling box, improve the heat exchange efficiency of the cold water in the cooling box, and make the cooling of the magnesium-aluminum alloy in the molding groove more uniform and efficient.

[0004] However, in actual use, cooling by water spraying will result in poor cooling effect due to uneven sandblasting. At the same time, when the cold water contacts the surface of the magnesium alloy rod, water vapor will splash onto the staff, and the cold water cannot be circulated for use. Utility Model Content
