Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting, in particular to a casting mould for automobile parts. Background Art
[0002] A casting mold is a mold made of other materials to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. Liquids such as iron and aluminum are then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed. In vehicle production, casting molds are essential processing equipment. Some parts are formed in one piece through casting, which is less costly and more efficient than other processing methods.
[0003] During casting, the two molds of the casting mold will be closed, and then aluminum liquid, iron liquid, etc. will be poured into the cavity formed by the two molds. After the parts are cast, the molded parts will be removed. However, after the parts are formed, they may be stuck in the mold cavity, which is inconvenient for the staff to remove. Therefore, a casting mold for automobile parts is proposed to address the above problems. Utility Model Content
