[0020] like Figure 1 , 2 As shown, this embodiment provides a pipe upsetting mold. The upsetting mold 10 includes an upper mold 11, a lower mold 12, a guide post 13 disposed on the upper mold 11, and a guide hole 14 disposed on the lower mold 12 for the guide post 13 to be inserted and connected.
[0021] The top surface of the lower mold 12 is provided with a first receiving groove 15 for accommodating the lower half of the tube 31. The lower mold 12 is provided with a positioning block 17 at the first end of the first receiving groove 15 to block the first end face of the tube 31. The lower mold 12 is provided with a sliding block 18 at the second end of the first receiving groove 15. The second end of the tube 31 is inserted into the sliding block 18 and abuts against the sliding block 18. The sliding block 18 slides along the length direction of the first receiving groove 15.
[0022] The bottom surface of the upper mold 11 is provided with a second receiving groove 16 for accommodating the upper half of the tube 31. The upper mold 11 is provided with an upper slider 19 at the second end of the second receiving groove 16, which is slidably disposed on the upper mold 11. The second end of the tube 31 is inserted into the upper slider 19 and abuts against the upper slider 19. The upper slider 19 slides along the length direction of the second receiving groove 16. The upper slider 19 is also provided with an inclined insertion block 20 for pushing the upper slider 19 and the lower slider 18 to move towards the first end of the first receiving groove 15 and the first end of the second receiving groove 16.
[0023] When using the pipe upsetting mold of this utility model, the pipe 31 can be placed in the first receiving groove 15 of the lower mold 12. The upper mold 11 moves downward, causing the second receiving groove 16 to completely cover the upper half of the pipe 31. The inclined insert block 20 on the upper mold 11 moves downward, pushing the upper slider 19 and the lower slider 18. The upper slider 19 and the lower slider 18 move simultaneously towards the first end of the first receiving groove 15 and the second receiving groove 16, squeezing the second end of the pipe 31, and the pipe 31 forms a convex shape. After completion, the upper mold 11 is moved upward, and the pipe 31 is removed. The upsetting mold 10 of this application only requires one mold 10 to realize the upsetting process of the pipe 31. It can be completed by a single person with a single mold, reducing the number of mold changes and the number of scrapped products due to mold changes and debugging, saving processing costs, and greatly improving production efficiency.
[0024] In this embodiment, the upper mold 11 includes an upper plate 21 and a lower plate 22 that is movably connected to the upper plate 21 via equal-height screws 23. The second receiving groove 16 and the lower slider 18 are both disposed on the lower plate 22.
[0025] Furthermore, a limiting post 24 is fixedly provided on the top surface of the lower plate 22 or the bottom surface of the upper plate 21. At least one first elastic element 25 is provided between the upper plate 21 and the lower plate 22.
[0026] As the upper mold 11 moves downward, the lower plate 22 first contacts the lower mold 12, and the first receiving groove 15 and the second receiving groove 16 completely enclose the tube 31. The upper plate 21 continues to move downward, driving the inclined insert block 20 to push the upper slider 19 and the lower slider 18 to move, squeezing the tube 31. This continues until the upper plate 21 or the lower plate 22 abuts against the limiting post 24, restricting the upper plate 21 from moving further.
[0027] Understandably, the first receiving groove 15 and the second receiving groove 16 are cavities for forming the pipe 31, and forming grooves for forming the convex bulge of the pipe 31 are provided in the first receiving groove 15 and the second receiving groove 16.
[0028] Specifically, the inclined insertion block 20 is fixed to the bottom surface of the upper plate 21, and the lower plate 22 is provided with an insertion hole 26 through which the inclined insertion block 20 can move.
[0029] Optionally, the bottom end of the inclined block 20 is provided with a first inclined surface 27 on the side near the upper slider 19 and the lower slider 18, and the upper slider 19 and the lower slider 18 are provided with a second inclined surface 28 on the side corresponding to the first inclined surface 27, which matches the first inclined surface 27.
[0030] Furthermore, a second elastic element 29 is provided between the lower slider 18 and the lower mold 12 to push the lower slider 18 to reset, and a third elastic element 30 is provided between the upper slider 19 and the lower plate 22 to push the upper slider 19 to reset.
[0031] Furthermore, the lower mold 12 is provided with a first slide groove or a first slide rail for the lower slider 18 to move and guide. The direction of the first slide groove or the first slide rail is consistent with the length direction of the first receiving groove 15. The lower plate 22 is provided with a second slide groove or a second slide rail for the upper slider 19 to move and guide. The direction of the second slide groove or the second slide rail is consistent with the length direction of the second receiving groove 16.
[0032] Understandably, the lower mold 12 is also provided with a first stop to prevent the lower slider 18 from disengaging from the first slide groove or the first slide rail, and the lower plate 22 is also provided with a second stop to prevent the upper slider 19 from disengaging from the second slide groove or the second slide rail.
[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
