[0002] The existing core-pulling slider is usually arranged in a form in which the inclined surface of the slider seat abuts against the inclined surface of the wedge block. This structure can easily cause the wedge block to be pushed back by the injection pressure during the injection molding process. Especially when the glue area is large, the injection pressure will produce a lateral thrust on the inclined surface of the wedge block, causing the wedge block to retreat and the position of the core-pulling slider to change, resulting in defective products.

[0003] The existing announcement number CN214872393U discloses a core pulling slider locking mechanism, including a slider seat for fixing the core pulling slider, a wedge block matched with the slider seat, and a driving member for driving the wedge block to move; the slider seat is provided with a first sliding surface and a second sliding surface, and the wedge block is provided with a first guide surface matched with the first sliding surface, and a second guide surface matched with the second sliding surface; the slider seat is configured to drive the wedge block to move through the driving member, and switch between a locked state and a sliding state. When the slider seat is in the locked state, the first sliding surface abuts against the first guide surface in a horizontal position, or when in the sliding state, the second sliding surface slides along the second guide surface. When the slider seat is in the locked state, the first sliding surface abuts against the first guide surface in a horizontal position to avoid the injection pressure from generating side pressure on the wedge block, thereby solving the problem of product defects caused by the retreat of the core pulling slider.
