Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, and more specifically, to a high-strength turbocharger housing casting mold. Background Art

[0002] A casting mold is a tool used to create castings. It's typically made of metal and has a specific shape and structure. The mold typically consists of an upper and lower mold, with a cavity in between to hold the liquid metal. During the casting process, the liquid metal is poured into the mold cavity. After cooling and solidification, the mold is opened to produce the desired casting shape.

[0003] During the casting process of the turbocharger housing, the lower mold will directly contact the high-temperature liquid metal. The temperature of the liquid metal is usually very high and will quickly transfer a large amount of heat to the lower mold. The existing cooling mechanism generally sets a cooling water channel inside the lower mold to allow the cooling water to circulate in the rice, thereby reducing the temperature of the mold. However, the design and processing of the cooling water channel is difficult. At the same time, the laying of the cooling pipe requires the processing of channels in the mold. These channels destroy the continuity of the mold material, thereby reducing the overall strength of the lower mold. Utility Model Content
