As shown in fig. 1 to 8, the complex-structure composite-angle slider core pulling structure comprises a slider insert 1, a slider seat 10, a shovel machine 6 and an inclined guide post 8, wherein a concave T-shaped guide groove mechanism is arranged at the front end of the slider seat 10, the concave T-shaped guide groove mechanism is an inclined concave T-shaped guide groove, an inclined convex T-shaped groove is formed in the tail end of the slider insert, and the slider seat 10 is connected with the slider insert 1 through the T-shaped groove. The front end of the slider seat 10 is positioned in counter bores at two sides of the concave T-shaped guide groove mechanism, slider springs 2 are placed in counter bores at two sides of the concave T-shaped guide groove mechanism, the slider seat 10 is arranged on the movable template 17 at two sides of the slider seat 10 through guide rails 4, and the guide rails 4 are fixed on the movable template 17 through guide rail locking screws A3 and guide rail locking screws B5. And a limiting screw 13 is arranged on the movable die plate 17 corresponding to the backward position of the sliding block seat 10, the inclined guide post 8 is arranged in the shovel machine 6, the shovel machine 6 is fixed on the fixed die plate 16 through a shovel machine locking screw A and a shovel machine locking screw B, and an inclined through hole is arranged on the sliding block seat 10 corresponding to the inclined guide post 8. The top of the movable mold insert 11 on the movable mold plate 17 is an inclined surface and is matched with the bottom surface of the slide block insert 1; a pressing plate 14 is arranged on the fixed die plate 16, an inclined plane is arranged on the pressing plate 14, and the inclined plane on the pressing plate 14 is matched with the top surface of the slide block insert 1.

As shown in fig. 9, the present invention derives a T-shaped groove structure capable of rotating 360 degrees at will, and the specific technical solution is as follows. The concave T-shaped guide groove mechanism comprises a slider rotating insert 19 and two slider seat inserts 18, the two sides of the front end of the slider seat 10 are respectively provided with one slider seat insert 18, the slider rotating insert 19 is arranged between the two slider seat inserts 18 at the front end of the slider seat 10, the slider rotating insert 19 is provided with a concave T-shaped groove 21, the two sides of the slider rotating insert 21 are symmetrically provided with positioning rotating shafts 20, slider rotating insert tightening screws 22 are inserted into the slider seat inserts 18 to position the slider rotating insert 19, and the slider seat inserts 18 are fixed at the front end of the slider seat 10 through insert locking screws 23.

The structure drives the sliding block seat to move backwards along the horizontal direction under the driving of the spring and the inclined guide post, and the sliding block insert moves backwards along the molded back-off mold opening direction under the action of the pressing plate, the movable mold insert and the sliding block T-shaped groove. When the slide block seat retreats backwards, the T-shaped groove drives the slide block insert to perform demolding movement, it is noted that the slide block insert is pressed by the mold insert 11 and the pressing plate 14 in the demolding and core pulling process to limit the movement direction, the slide block insert can only move downwards in an angle along the product back-off demolding direction, and the slide block insert is ensured to be connected with the slide block seat after the slide block insert is subjected to core pulling and retreating and the convex T-shaped groove at the tail part of the insert is not separated from the concave T-shaped groove of the slide block according to the calculation of a trigonometric function.
