[0019] The lower die base is provided with a clearance groove, which is arranged corresponding to the second insert 501. The first insert 401 is located inside the second insert 501, and the first insert 401 is slidably connected to the second insert 501. The second insert 501 can guide the core pulling action of the first insert 401.

[0020] The upper slider 4 is fixedly connected with travel limit blocks 403 on both sides, and the lower slider 5 is provided with limit grooves 503 on both sides.

[0022] The working principle of the utility model is: when the utility model is in use, the seat plate 3 is fixedly connected to the upper template. When the mold is opened, the upper template and the seat plate 3 will rise. During the rising process of the seat plate 3 and the inclined pin 1, the upper slider 4 is first pulled out to the part away from the undercut 6 under the action of the inclined pin 1, thereby leaving a gap beside the undercut 6 on the connector. Then, as the inclined pin continues to move upward, the inclined pin 1 will drive the lower slider 5 to be pulled out to the part away from the undercut 6. Since the gap is left by the withdrawal of the first insert 401, the second insert 501 can push the undercut 6 to be pulled out.
