During the production process of the internal core-pulling slider, it is usually necessary to install it on a stamping machine using a mold of the corresponding shape according to the shape of the slider, and then inject the raw material for making the internal core-pulling slider into the mold for one-piece molding.

[0003] When the mold is used to perform integral molding of the internal core-pulling slider, the formed internal core-pulling slider will be embedded in the mold. When it needs to be taken out, it is inconvenient to hold and take it out from the groove inside the mold because the edge of the formed internal core-pulling slider is closely fitted with the inner wall of the mold, resulting in a long removal time, which reduces the production efficiency of the internal core-pulling slider.
