Description

Technical Field

[0002] A casting mold refers to a structure that is first made of other easily moldable materials into the shape of a part in order to obtain the structural shape of the part. Then, the mold is placed in a sand mold, and a cavity with the same structural dimensions as the part is formed in the sand mold. Then, a fluid with fluidity is poured into the cavity. After the fluid cools and solidifies, a part with exactly the same shape and structure as the mold can be formed. Common casting molds are divided into ordinary manual molding, common wooden models, plastic models, and mechanical molding mostly using metal models, etc.

[0003] In the casting process of existing casting molds, impurities and foreign objects such as coatings, molding materials, or refractory materials often mix into the molten alloy liquid of the mold cavity, resulting in a situation where the surface or interior of the cast workpiece has a different composition from the original design, seriously affecting the quality of the cast workpiece. Or, due to the insufficient tight fit between the female mold and the male mold of the casting mold, the cast workpiece may be deformed or even cracked, which will also reduce the yield rate of the cast workpiece, lower the yield rate, and result in low production efficiency. Moreover, due to factors such as the small internal space of the casting cavity and the large density and small flow of the casting liquid, the flow of the casting liquid may be uneven, leading to the occurrence of pores or even incomplete castings. For example, a Chinese patent discloses "a casting mold for preventing casting defects", with the application number: "CN202221193410.9", which includes: a wall body, a fixing device, a mold table, a heat insulation layer, a high-temperature heating plate, a bottom plate, a rubber pad, a water tank, and a water injection hole.
