In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

In the automobile industry, in order to prevent abnormal noise and a large wind resistance coefficient during traveling, a mold is required to accurately finish a body and parts of an automobile, and a good demolding process is required for the mold of the body and the parts.

Conventional molds compress the material into a desired shape through a cavity and plate.

However, the mold release in the above manner is difficult, and a less smooth surface of the material is liable to occur due to uneven expansion of the material.

Therefore, a new automobile mold which is convenient for demolding is needed.
