One end of the support shell 401 is a frustum-shaped empty shell, and two curved plates are fixedly connected to the surface of the frustum-shaped empty shell. The support shell 401 is sleeved on the outer surface of the upper end of the clamping frame 2, and the inner side of the support shell 401 is fixedly connected to the support spring 402. The positioning rod 403 has a threaded rod shape and is threadedly connected to the clamping frame 2, and the support spring 402 is sleeved on the outer side of the positioning rod 403. The tensioning mechanism 4 can first clamp the mold so that the mold can be adjusted in time after entering the position, and after the adjustment is completed, the support shell 401 is fixed by the positioning rod 403, so that the mold position can be fixed.

[0025] The upper surface of the base plate 1 is connected with a pad 5 by bolts, and the upper surface of the base plate 1 is connected with a slide plate 6 by bolts. The slide plate 6 is a flat plate in appearance, and a trapezoidal slide is opened at the midline position of the upper surface of the slide plate 6. The slide plate 6 can provide a platform to provide guidance and support for the movement of the transverse frame 7.

[0026] A transverse frame 7 is slidably connected to the inner side of the slide groove plate 6. The upper end of the transverse frame 7 is a flat plate, and the lower end of the transverse frame 7 is a trapezoidal sliding key. The end face of the trapezoidal sliding key of the transverse frame 7 is provided with two circular through holes of different diameters. The transverse frame 7 can drive the upper mechanism to slide horizontally, and use the two through holes of different diameters at the lower end to achieve one-way blocking of the inner mechanism from passing through.

[0027] A drag motor 8 is fixedly connected to the inner side of the right end of the slide plate 6, and a drag wheel 9 is fixedly connected to the output end of the drag motor 8. A drag chain 10 is sleeved on the outer side of the drag wheel 9, and the drag chain 10 passes through the transverse frame 7. The drag wheel 9 is cylindrical in shape and has teeth on the surface. The surface of the drag wheel 9 is elastic. There is an annular belt in the middle of the drag chain 10. A blocking bean 101 is fixedly connected to the surface of the annular belt of the drag chain 10. The blocking bean 101 passes through the circular through hole of the transverse frame 7. The blocking bean 101 is elastic. The drag wheel 9 can drive the drag chain 10 to rotate and use the elasticity of the surface to make the blocking bean 101 pass smoothly, and use the blocking bean 101 to push the transverse frame 7 during the movement, and squeeze into the inner side of the transverse frame 7 after being blocked.

[0028] A dragging belt 11 passes through the inner side of the transverse frame 7, and a feed box 12 is meshed with the upper end of the dragging belt 11. Both ends of the dragging belt 11 are round shafts and are rotatably connected to the transverse frame 7. An annular linkage belt is sleeved on the outer side of the round shaft of the dragging belt 11, and the linkage belt is in contact and friction with the drag chain 10. A toggle tooth 111 is fixedly provided above the round shaft at one end of the dragging belt 11, and the toggle tooth 111 is meshed with the feed box 12. The dragging belt 11 can utilize the linkage belt to contact and rub with the extruded drag chain 10, so that it is driven to rotate, thereby pushing the toggle tooth 111 to rotate, so that the toggle tooth 111 can rotate when the feed box 12 is blocked.

[0029] The feed box 12 is slidably connected to the upper surface of the transverse frame 7, and the upper end of the feed box 12 is fixedly connected to the extension frame 13. The feed box 12 is composed of a shell 121, a feed spring 122, abutment rod 123 and a rack plate 124. The shell 121 is a square shell, and the rack plate 124 is fixedly connected to the side of the square shell. The feed spring 122 is fixedly connected to the inner side of the shell 121. The end of the feed spring 122 away from the shell 121 is fixedly connected to the transverse frame 7, and the outer surface of the shell 121 is fixedly connected to the abutment rod 123. The feed box 12 can contact the outer contour of the mold through the abutment rod 123, and use the feed spring 122 to push the shell 121 so that the abutment rod 123 is always close to the mold, and the extension frame 13 is slidably connected to the cushion block 5.

[0030] Working principle: When in use, first rotate the top cone 3 to fix one end of the mold, push the support shell 401 through the support spring 402 to fix the other end of the mold, rotate the positioning rod 403 to tighten the mold, push the shell 121 through the feed spring 122 to make the abutment rod 123 close to the mold, start the drag motor 8 to drive the drag wheel 9 to rotate, so that the drag wheel 9 drives the drag chain 10 to rotate, so that the blocked beans 101 carry the transverse moving frame 7 to move transversely on the inner side of the slide plate 6 and drive the abutment rod 123 at the upper end to move along the axial direction of the mold, and the axial diameter of the mold changes. When the hour feed spring 122 pushes the rod housing 121 forward, when the axial diameter of the mold becomes larger, the abutment rod 123 is blocked, so that the transverse frame 7 cannot move forward, and the blocking beans 101 are squeezed to enter and pass through the round hole of the transverse frame 7. At the same time, when the blocking beans 101 pass through the round hole of the transverse frame 7, the dragging belt is twisted through friction, so that the shifting tooth 111 rotates, and the shifting tooth 111 pushes the rack plate 124 to make the housing 121 retreat, so that the abutment rod 123 can move along the mold, and at the same time, the feed box 12 collects the mold trajectory and forms the feeding trajectory of the turning tool through the stretching frame 13.
