[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figures 1 to 6 As shown, in this embodiment, a bending forming mold includes an upper mold base 1, a plunger 2, a pendulum block 3, a slider 4 and a lower mold base 5. The upper end of the plunger 2 is fixed to the lower end of the upper mold base 1, and the lower end of the slider 4 slides on the lower mold base 5 along the horizontal direction. The upper end of the slider 4 is equipped with a first guide wheel 6, which rolls on the plunger 2. The inner end of the slider 4 presses outward on the inner wall of the product 19. The lower end of the upper mold base 1 is fixed with a guide plate 7, and the guide plate 7 is provided with a guide groove 8. The lower mold base 5 is fixed with a pendulum seat 9, one end of the pendulum block 3 is hinged on the pendulum seat 9, and the other end of the pendulum block 3 is rotatably connected to the second guide wheel 10, which rolls in the guide groove 8. A pressure strip 11 is fixed on the pendulum block 3, and the pressure strip 11 presses on the outer wall of the product 19.

[0024] The upper die base 1 and the lower die base 5 are closed together, and the insert knife 2 moves downward. Relying on the pressure of the inclined surface, the first guide wheel 6 moves outward, driving the slider 4 to move outward. The inner end of the slider 4 will extrude the inner wall of the product 19. At the same time, in the process of the upper die base 1 driving the insert knife 2 to move downward, the guide plate 7 also moves downward, and the second guide wheel 10 in the guide groove 8 of the guide plate 7 is forced to move. Since the second guide wheel 10 is on the pendulum block 3, and the pendulum block 3 swings on the pendulum seat 9 of the lower die base 5, the pendulum block 3 swings downward at a certain angle, and the pressure strip 11 connected to the pendulum block 3 swings inward to extrude the outer wall of the product 19.

[0025] An upper beating plate 12 is installed in the middle of the lower end of the upper die base 1. The upper beating plate 12 presses on the upper surface of the product 19. The upper beating plate 12 moves downward with the upper die base 1 and presses on the upper surface of the product 19 to form it.

[0026] The inner end of the slider 4 is installed with a lower die bending strip 13, the upper end of the lower die bending strip 13 is pressed against the inner top of the product 19, and the outer end of the lower die bending strip 13 is pressed against the inner wall of the product 19. The lower die bending strip 13 cooperates with the pressure strip 11 outside the product 19 to extrude the side wall of the product 19.

[0027] A rebound cylinder 14 is installed on the lower die base 5, and the movable end of the rebound cylinder 14 is connected to the slider 4. After the product 19 is formed, the upper die base 1 retreats, the insert 2 leaves the slider 4, and the rebound cylinder 14 controls the slider 4 to withdraw, making it convenient to take away the product 19.

[0028] A fixing bar 15 is provided on the side of the slider 4, and the fixing bar 15 is fixed on the lower mold base 5. The fixing bar 15 limits the moving direction of the slider 4. During the installation process, the slider 4 is placed first, and the fixing bar 15 is locked on the lower mold base 5 on the side of the slider 4. The formed slide groove allows the slider 4 to move in the horizontal direction.

[0029] An arcuate surface 16 is provided on the inner side of the slider 4 , and the bead 11 slides on the arcuate surface 16 . When the bead 11 is restrained by the swing block 3 and swings, the arcuate surface 16 on the slider 4 can assist the bead 11 in swinging.

[0030] The lower end of the lower mold base 5 is locked with a mounting shaft 17, and the middle part of the mounting shaft 17 is rollingly connected with a roller 18. Under the action of the roller 18, the entire mold can be adapted to different production positions and is easy to move.

[0031] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
