[0022] Example

[0023] Please see Figures 1-5This utility model provides a technical solution: a noise-reducing stamping die, including a soundproof box 1 and a push plate 3. The push plate 3 is slidably connected inside the soundproof box 1 and moves along the interior of the soundproof box 1. A soundproof plate 2 is rotatably connected to one side of the soundproof box 1. The soundproof box 1 and the soundproof plate 2 work together to reduce the noise generated during the stamping process. A rack 12 is symmetrically fixedly connected to the top of the push plate 3. The movement of the push plate 3 moves the rack 12. A third rotating shaft 20 is symmetrically rotatably connected inside the soundproof box 1. A third gear 13 is fixedly connected to one end of the third rotating shaft 20. The rotation of the third gear 13 moves the third rotating shaft 20. One side of the third gear 13 meshes with the rack 12. The movement of the rack 12 moves the third gear 13. A second rotating shaft 18 is rotatably connected inside the soundproof box 1. Synchronous pulleys 14 are fixedly connected to the outer sides of both the third rotating shaft 20 and the second rotating shaft 18. The rotation of the synchronous pulleys 14 moves the second rotating shaft 18. The synchronous pulleys 14 are connected by a synchronous belt 15. Under the action of the synchronous belt 15, the two sets of synchronous pulleys 14 rotate simultaneously. The sound insulation plate 2 is fixedly connected to the inside of the sound insulation plate 2. The rotation of the first shaft 17 drives the sound insulation plate 2 to rotate. The two ends of the first shaft 17 pass through the two sides of the sound insulation box 1 and are fixedly connected to the second gear 7. The rotation of the second gear 7 drives the first shaft 17 to rotate. The two ends of the second shaft 18 pass through the two sides of the sound insulation box 1 and are fixedly connected to the first gear 6. The rotation of the second shaft 18 drives the first gear 6 to rotate. One side of the first gear 6 meshes with the second gear 7. The rotation of the first gear 6 drives the second gear 7 to rotate. The second gear 7 is larger than the first gear 6. Therefore, when the transmission is carried out, the first gear 6 drives the second gear 7 to rotate. Therefore, the rotation stroke is relatively large, so that the second gear 7 drives the sound insulation plate 2 to open and close, which can be matched with the movement stroke of the rack 12.

[0024] Furthermore, a mounting base 8 is fixedly connected to the top of the push plate 3. The push plate 3 moves, causing the mounting base 8 to move as well. A mounting frame 19 is fixedly connected to the top of the mounting base 8. The mounting base 8 moves, causing the mounting frame 19 to move as well. A lower mold 9 is fixedly connected to the top of the mounting base 8. The mounting base 8 moves, causing the lower mold 9 to move as well. An upper mold 10 is slidably connected inside the mounting frame 19. The upper mold 10 moves inside the mounting frame 19 to perform molding.

[0025] Furthermore, a cylinder 11 is fixedly connected to the top of the mounting frame 19. The output end of the cylinder 11 passes through one side of the mounting frame 19 and is fixedly connected to the upper mold 10. After the cylinder 11 is turned on, it moves the upper mold 10.

[0026] Furthermore, the bottom of the soundproof box 1 is symmetrically provided with connecting grooves 21, which are located at one end of the bottom of the push plate 3.

[0027] Furthermore, the bottom of the push plate 3 is symmetrically provided with wheels 5. The push plate 3 moves along with the wheels 5, making the pulling of the push plate 3 smoother. The wheels 5 are slidably connected to the connecting groove 21. When the push plate 3 is put into the soundproof box 1, the wheels 5 are stored in the connecting groove 21.

[0028] Furthermore, a handle 4 is fixedly connected to one side of the push plate 3 to facilitate the movement of the push plate 3.

[0029] Furthermore, the bottom of the soundproof box 1 is symmetrically and fixedly connected with support legs 16, the height of which is the same as the height of the wheels 5, so that the device can be placed stably on a flat surface.

[0030] In use, when a noise-reducing stamping die is needed for stamping operations, the operator pulls the push plate 3 via the handle 4 on one side of the push plate 3. The push plate 3 moves along the inside of the soundproof box 1, simultaneously moving the mounting base 8, mounting bracket 19, lower die 9, rack 12, and wheel 5. Since the rack 12, which is symmetrically fixed at the top of the push plate 3, meshes with the third gear 13, the movement of the rack 12 will drive the third gear 13 to rotate. The rotation of the third gear 13 will then drive the third rotating shaft 20 to rotate. The synchronous pulley 14 fixed on the outside of the third rotating shaft 20 will rotate accordingly. Through the synchronous belt 15, the synchronous pulley 14 on the outside of the second rotating shaft 18 will also rotate synchronously, thereby driving the second rotating shaft 18 to rotate. The first gear 6 at both ends of the second rotating shaft 18 meshes with the second gear 7 at both ends of the first rotating shaft 17. Therefore, when the second rotating shaft 18 rotates, the first gear 6 will drive the second gear 7 to rotate. Wheel 7 rotates, causing the first shaft 17 to rotate. The sound insulation plate 2, fixed to the outside of the first shaft 17, opens outward around the rotating connection with the sound insulation box 1. After the sound insulation plate 2 opens, the material to be processed is placed on the lower mold 9, and the push plate 3 is pushed back into the sound insulation box 1. Under the linkage of each component, the sound insulation plate 2 closes again, forming a closed space with the sound insulation box 1. The cylinder 11 on the top of the mounting frame 19 is opened, and the output end of the cylinder 11 drives the upper mold 10 to move downward inside the mounting frame 19, cooperating with the lower mold 9 to stamp and form the material. The sound insulation box 1 and the sound insulation plate 2 work together to effectively reduce the noise generated during the stamping process from spreading outward. At the same time, when the push plate 3 is put back into the sound insulation box 1, the wheel 5 is stored in the connecting groove 21 at the bottom of the sound insulation box 1. Since the height of the support leg 16 is the same as that of the wheel 5, the device can be placed stably on the plane.
