Detailed Implementation
[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an arc-shaped liner processing mold, including a support frame 1, a lower mold 2 fixedly connected inside the support frame 1, a cylinder 3 fixedly connected to the outer wall of the lower mold 2, a connecting plate 4 fixedly connected to the output end of the cylinder 3, the outer wall of the connecting plate 4 slidably connected to the inside of the lower mold 2, a rack 5 fixedly connected to the outer wall of the connecting plate 4, a limit plate 6 slidably connected to the outer wall of the rack 5, the outer wall of the limit plate 6 fixedly connected to the inside of the lower mold 2, a gear 7 meshing with the tooth end of the rack 5, the outer wall of the gear 7 rotatably connected to the inside of the lower mold 2, a connecting rod 8 fixedly connected to the outer wall of the connecting plate 4, the outer wall of the connecting rod 8 slidably connected to the inside of the lower mold 2, a clamping plate 9 fixedly connected to the outer wall of the connecting rod 8, and a driving assembly provided inside the support frame 1.
[0024] Specifically, the support frame 1 fixes the lower mold 2, and the lower mold 2 fixes the cylinder 3. By activating the cylinder 3, the connecting plate 4 can slide inside the lower mold 2. The connecting plate 4 can drive the rack 5 to slide on the inner wall of the limiting plate 6. The rack 5 can drive the gear 7 to rotate inside the lower mold 2. The rotation of the gear 7 can drive the two racks 5 to move towards each other, and at the same time drive the connecting plate 4 to slide. The connecting plate 4 can drive the connecting rod 8 to slide inside the lower mold 2. The connecting rod 8 can drive the clamping plate 9 to clamp and fix the liner, which can limit the liner and prevent the liner from shifting during stamping, thus affecting the stamping effect.
[0025] Reference Figure 1 The drive assembly includes an electric cylinder 10, the outer wall of which is fixedly connected to the inside of the support frame 1. A sliding plate 11 is fixedly connected to the output end of the electric cylinder 10. An upper mold 13 is fixedly connected to the lower surface of the sliding plate 11. A limit post 12 is slidably connected inside the sliding plate 11. The outer wall of the limit post 12 is fixedly connected to the inside of the support frame 1.
[0026] Specifically, the support frame 1 fixes the electric cylinder 10. Activating the electric cylinder 10 moves the sliding plate 11, which in turn drives the upper mold 13 to perform stamping. The sliding plate 11 slides on the outer wall of the limiting post 12, which in turn drives the upper mold 13 to move stably. The limiting post 12 limits the sliding plate 11, ensuring that the sliding plate 11 slides stably.
[0027] Reference Figure 4 The lower mold 2 has a mold core 14 inside, and a sliding column 15 is slidably connected inside the mold core 14. A locking block 16 is fixedly connected to the outer wall of the sliding column 15. The outer wall of the locking block 16 is slidably connected to the inside of the lower mold 2 and the mold core 14. A first spring 17 is provided on the outer wall of the sliding column 15. One end of the first spring 17 is fixedly connected to the inside of the lower mold 2, and the other end of the first spring 17 is fixedly connected to the outer wall of the locking block 16.
[0028] Specifically, by setting a mold core 14 inside the lower mold 2, the liner plate can be processed into different shapes. By driving the mold core 14 to slide inside the lower mold 2, the clamping block 16 can be squeezed by the inner wall of the lower mold 2. The clamping block 16 can drive the sliding column 15 to slide inside the mold core 14. The sliding column 15 can drive the first spring 17 to be compressed. The first spring 17 has a rebound effect, which can drive the clamping block 16 to slide in the groove set inside the lower mold 2, thereby achieving the effect of limiting the mold core 14 so as to quickly install the mold core 14.
[0029] Reference Figure 4 The lower mold 2 has a sliding column 19 slidably connected inside, and a connecting piece 20 is fixedly connected to the outer wall of the sliding column 19. The outer wall of the connecting piece 20 is slidably connected to the interior of the lower mold 2. A second spring 21 is provided on the outer wall of the sliding column 19. One end of the second spring 21 is fixedly connected to the interior of the lower mold 2, and the other end of the second spring 21 is fixedly connected to the outer wall of the connecting piece 20. A sliding block 18 is fixedly connected to the outer wall of the sliding column 19. The outer wall of the sliding block 18 is slidably connected to the interior of the lower mold 2, and the outer wall of the sliding block 18 is connected to the outer wall of the locking block 16.
[0030] Specifically, by pulling the connecting piece 20, the sliding column 19 can be moved to slide inside the lower mold 2. The sliding column 19 can be moved to compress the second spring 21. The second spring 21 has a rebound function, which can ensure that the sliding block 18 does not affect the locking block 16 without the action of external force. The sliding column 19 can be moved to move the sliding block 18 inside the lower mold 2. The sliding block 18 can be pressed to push the locking block 16, which can be moved to slide out of the lower mold 2, so as to achieve the effect of quick disassembly of the mold core 14.
[0031] Working principle: When this processing mold is needed, the liner material is first placed on the upper surface of the lower mold 2. By starting the cylinder 3, the connecting plate 4 can slide inside the lower mold 2, and at the same time, the rack 5 can slide on the inner wall of the limiting plate 6. While the rack 5 is sliding, the gear 7 can rotate inside the lower mold 2, which in turn drives the two racks 5 to slide at the same time, and at the same time drives the connecting plate 4 and the connecting rod 8 to slide inside the lower mold 2, which in turn drives the clamping plate 9 to clamp and fix the liner, so as to prevent the liner from shifting during stamping and affecting the processing effect.
[0032] When the mold core 14 needs to be replaced, the sliding column 19 can be slid inside the lower mold 2 by manually pulling the connecting piece 20. At the same time, the second spring 21 is compressed, which in turn causes the sliding block 18 to squeeze the locking block 16. Simultaneously, the first spring 17 is compressed, and the sliding column 15 slides inside the mold core 14. When the sliding block 18 pushes the locking block 16 out of the lower mold 2, the mold core 14 is slid out of the lower mold 2, achieving the effect of quickly disassembling the mold core 14 and facilitating the replacement of the mold core 14. This processing mold can not only fix the liner plate, but also achieve the effect of quickly replacing the mold core 14 to accommodate liners with different curvatures.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
