Description

Technical Field

[0001] The utility model relates to the field of automobile parts manufacturing, and more specifically to a casting mold auxiliary device for automobile parts production and processing. Background Art

[0002] The casting mold is an important part of the casting process, which is used to obtain the required structural shape of the parts. In the manufacturing process, the structural shape of the part is first made of other easily moldable materials, and then the mold is placed in the sand mold, and a cavity with the same structural size as the part is formed in the sand mold. Then, a flowing liquid is poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

[0003] When making automotive parts, it is usually necessary to use a casting mold with a cylindrical cavity shape. After the cylindrical metal is formed, it is demolded. However, since the molded metal fits tightly into the mold and the surface is smooth, it is difficult to demold, which increases the difficulty of this work. In addition, the liquid metal is close to the inner wall of the mold, and the exchange with the ambient temperature is fast and the heat is dissipated faster. The outer surface has been formed, while the seal in the center is slowly formed. It takes a long time to make a large number of molds. Utility Model Content
