Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a casting mold for metal parts processing. Background Art

[0002] As the foundation of the automotive industry, auto parts are a necessary factor in supporting the sustainable and healthy development of the automotive industry. In particular, the current vigorous and full-scale independent development and innovation in the automotive industry requires a strong parts system to support it.

[0003] At present, most of the automotive metal parts are manufactured through casting molds. In order to obtain the structural shape of the part, the casting mold is made of other easily moldable materials in advance, and then the mold is placed in the sand mold, so that a cavity with the same size as the part structure is formed in the sand mold. Then, a flowing liquid is poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed;

[0004] There are two common ways to make a cavity. The first is to put the sample directly into the cavity, take it out after the cavity shape is made; the second is to place a wax mold made in advance in the sand, and then pour liquid to cast it into a product. Both methods have a disadvantage, that is, the poured product needs to be cooled for a long time before it can be taken out of the mold, or the mold can be opened directly to expose the product to the air for cooling, which will result in a longer production time.

[0005] Therefore, a casting mold for metal parts processing was invented. Utility Model Content
