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.

At this time, the structure of the mold must adopt the structure of the slider, the core of the hole is made movable, and the inclined guidepost is used to cooperate with the fixed mold, and the slider moves with the mold opening or closing. This kind of movement is called core pulling.

The core-pulling mechanism is a common mechanism in the mold. The core-pulling mechanism usually moves together with the upper mold and uses positioning or guiding mechanisms such as guide blocks to ensure the accuracy of the core-pulling. In order to simplify the mold structure and reduce the mold space.

The common core-pulling mechanism is mostly driven by a cylinder to complete the core-pulling. There are various structures such as positive core-pulling and reverse core-pulling. The reverse core-pulling structure takes up less space than the positive core-pulling structure. There are fewer restrictions on mold space.
