Molds, various molds and tools used in industrial production to obtain required parts by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods. In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. At present, the injection mold has become a very common mold used in the industrial production process. The slider is a mold component that can slide perpendicular to the mold opening direction or at a certain angle to the mold opening direction during the mold opening action. For some Parts with undercuts are often demoulded normally only by adopting a slider structure. But when the molded product is an arc-shaped hollow product, arc core-pulling molding is required

The core-pulling system is used to handle the position where the product cannot be demolded on the parting surface. It is a special structure of the mold.

Core-pulling is a definition: a mechanism that ensures the smooth demolding of the product, also called a slider.

For example, there is a hole on the side of a plastic part. After the mold is opened, if the core of the hole is not removed, the product cannot be ejected.
