[0015] A stable secondary slider positioning mechanism, comprising a slider seat 1 and a shovel base 7, wherein the slider seat 1 is provided with a horizontal and vertical through slideway, wherein the shovel base 7 is slidably arranged in the vertical through slideway of the slider seat 1, wherein a third slider core 14 is slidably arranged in the horizontal through slideway of the slider seat 1, wherein the lower part of the shovel base 7 passes through a third slider vertical through hole on the third slider core 14, wherein the third slider core 14 is provided with a sliding hole 1401 which passes through both sides, wherein the sliding hole 1401 has a width structure, wherein a third pin connected to the slider seat 1 passes through the sliding hole 1401 10. A fourth slider core 15 is rotatably connected to the slider seat 1 through a fourth pin 11. A first slider core 12 and a second slider core 13 are rotatably connected to the fourth slider transverse through hole 1501 of the fourth slider core 15 through a first pin 8 and a second pin 9. The front portion of the third slider core 14 extends into the fourth slider transverse through hole 1501. The first slider core 12 and the second slider core 13 are respectively located on the upper and lower sides of the front portion of the third slider core 14. The outer end of the fourth slider core 15 is connected to the secondary injection molded product 16.

[0016] When the mold is opened, the shovel base 7 moves upward, driving the third slider core 14 to move to the right. At this time, due to the action of the tube block 6, the slider seat 1 remains stationary. Driven by the third slider core 14, the first slider core 12 and the second slider core 13 only move in the vertical direction (limited by the first pin 8 and the third pin 10), and are separated from the longitudinal undercut of the secondary injection molded product 16. When the third slider core 14 continues to move to the right, the right end of the third slider core 14 hits the inclined surface of the tube block 6, forcing the tube block 6 to move gradually upward, the spring 5 is compressed, and the slider seat 1 is separated from the limit of the tube block 6. At this time, the left side of the waist-shaped hole of the third slider core 14 contacts the third pin 10, and the shovel base 7 drives all the cores to move to the right together, completely separating from the horizontal lateral undercut of the secondary injection molded product 16.

[0017] Both sides of the slider seat 1 are provided with sliding position pressing plates 2 .

[0018] The lower end of the shovel base 7 is provided with an anti-locking block 3 in contact with the shovel base 7 .

[0019] The first slider core 12 and the second slider core 13 are both in contact with the front inclined surface of the third slider core 14, and a dovetail slide groove and a slideway that are slidably connected to each other are provided between the contact inclined surfaces.

[0020] The rear end of the third slider core 14 is exposed to the outside of the horizontal through slideway of the slider seat 1, and a pipe block 6 is provided on the exposed end. A spring 5 is provided on the upper part of the pipe block 6, and the spring 5 is installed in the pressing block 4.

[0021] A wear-resistant block 17 is provided on the top of the slider seat 1 .
