Description

Technical Field

[0001] The utility model relates to the technical field of automobile mold production, in particular to a trimming device for automobile molds. Background Art

[0002] The most important component of automotive molds is the panel mold. This type of mold is primarily a cold stamping mold. Broadly speaking, "automotive molds" refers to the molds used to manufacture all automotive parts. Examples include stamping molds, injection molds, forging molds, casting wax molds, and glass molds.

[0003] However, traditional automobile molds are trimmed during production. When an automobile mold is trimmed, the angle of the automobile mold needs to be changed and then trimmed again. This is generally done by workers manually adjusting the automobile mold. This operation is troublesome, time-consuming and labor-intensive, which reduces production efficiency. In addition, when trimming the automobile mold, flying waste chips will splash onto surrounding workers, causing physical harm to the workers. Therefore, it is urgent to solve this problem.
