detailed description:

The present invention will be further described below in conjunction with the examples, the purpose is only to better understand the contents of the present invention, therefore, the examples given do not limit the protection scope of the present invention.

Refer to Fig. 1 and Fig. 2, including the upper die assembly and the lower die assembly. The upper die assembly includes the upper die plate 1 and the upper die angle steel 2. On the flat plate 1, the upper mold angle steel 2 is welded by the upper mold reinforcement plate 3. The lower mold assembly includes the lower mold bottom plate 9 and two lower mold angle steels 4. The lower mold bottom plate 9 is fixed and installed on the lower working surface of the press with bolts. Bolts are installed on the bottom plate 9 with two lower mold adjusting plates 8, and the lower mold adjusting plates 8 are provided with long holes for left and right adjustment. The two lower mold adjusting plates 8 are respectively welded with a lower mold positioning block 7, and the lower mold positioning block 7. A lower mold semicircle positioning module 6 is welded on the top, and a lifting mechanism is arranged between the two lower mold adjusting plates 8. The lifting mechanism includes a lower mold angle adjustment block 11 and a lower mold angle adjustment female block 10 welded on the bottom plate 9 of the lower mold. , the angle adjustment block 11 of the lower mold and the angle adjustment female block 10 of the lower mold are clamped with two oblique irons 13 connected by inclined faces, and the angle adjustment female block 10 of the lower mold is installed with an upper oblique iron 13 relative to the lower oblique iron 13 up and down Sliding adjustment screw 12 (the lead screw rotates inside and outside to adjust the upper slanting iron 13 to move up and down), the locking nut 15 is installed on the adjusting screw 12, and two lower mold semicircle positioning modules 6 are welded on the upper slanting iron 13, the lower mold The semicircle positioning module 6 is finished with a smooth semicircular draw-in groove, and the lower ends of the two lower mold angle steels 4 can be positioned on the lower mold semicircle on the upper inclined iron 13 and the lower mold adjusting plate 8 through the two lower mold positioning pins 5 respectively. The module 6 slides in the draw-in slot and forms an included angle, the lower die angle steel 4 is welded with a fixed block 14 , and the lower die positioning pin 5 is welded on the fixed block 14 .
