[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0022] A reverse core-pulling slider structure of an automobile interior trim molding die comprises a core-pulling slider 1, a cylinder fixing seat 2, a cylinder 3, a cylinder connecting head 4, a rotating shaft I5, a rotating shaft I connecting block 6, a rotating shaft II7 and a rotating shaft II connecting block 8; wherein: the cylinder fixing seat 2 is provided with the cylinder 3, the telescopic shaft of the cylinder 3 is hingedly connected to the cylinder connecting head 4, the cylinder connecting head 4 is fixedly connected to the rotating shaft I5, the bottom of the rotating shaft I5 is hingedly connected to the rotating shaft I connecting block 6, and the rotating shaft I connecting block 6 is fixedly connected to the rotating shaft II7; a rotating shaft II connecting block 8 is fixedly connected to one side of the rotating shaft I connecting block 6, and a core-pulling slider 1 is fixedly connected to the bottom of the rotating shaft II connecting block 8.

[0023] Optimized: The oil cylinder 3 is installed on the top of the oil cylinder fixing seat 2 by bolts. An oil inlet pipeline and an oil return pipeline are installed on the top of the oil cylinder 3. The telescopic shaft of the oil cylinder 3 and the oil cylinder connector 4 are connected by threads and locked by a locking nut. The rotating shaft I5 is a straight axis, and the rotating shaft I5 is transversely fixed to the end of the oil cylinder connector 4. The rotating shaft I connecting block 6 is sleeved on the outside of the rotating shaft I5, and the rotating shaft I connecting block 6 and the oil cylinder connector 4 form a hinged connection. The rotating shaft II7 is a straight axis, and the rotating shaft II7 is transversely fixed to the end of the rotating shaft I connecting block 6. A rotating shaft II connecting block 8 is fixed to one side of the rotating shaft I connecting block 6 by bolts, and a core-pulling slider 1 is fixed to the bottom of the rotating shaft II connecting block 8 by bolts.

[0024] The working principle of the undercut core-pulling slider structure of the automotive interior molding mold is as follows: the rear end of the oil cylinder is pushed out through oil, the rotating axis I is movable, and the rotating axis II is fixed. The oil cylinder connector and the rotating axis I connecting block are pushed forward driven by the rotating axis I. The rotating axis I connecting block and the rotating axis II connecting block are fixed together, and the rotating axis I connecting block rotates around the rotating axis II to drive the rotating axis II connecting block to rotate. The slider is fixed to the rotating axis II connecting block. The rotating axis II connecting block rotates around the rotating axis II to drive the slider to move. When the oil cylinder moves forward, the slider moves backward, and when the oil cylinder moves backward, the slider moves forward.
