[0024] 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.

[0025] Reference Figures 1-3This utility model provides an embodiment of a high-precision stamping die for refrigerator stamping parts, comprising a base 1, a lower stamping block 2 fixedly connected to the upper surface of the base 1, a motor 3 fixedly connected to the outer wall of the lower stamping block 2, a worm gear 4 fixedly connected to the output end of the motor 3, the outer wall of the worm gear 4 rotatably connected to the inner wall of the lower stamping block 2, a worm wheel 5 meshing with the tooth end of the worm gear 4, a first gear 6 fixedly connected to the inner wall of the worm wheel 5, a second gear 7 meshing with the tooth end of the first gear 6, a telescopic plate 8 rotatably connected to the outer wall of the second gear 7, and a cleaning brush 9 rotatably connected to the inner wall of the telescopic plate 8, the lower surface of the cleaning brush 9... The upper surface of the lower stamping block 2 is slidably connected to the upper surface of the lower stamping block 2. The upper surface of the lower stamping block 2 is fixedly connected to the limit plate 10. The upper surface of the base 1 is provided with a stamping assembly, which includes a sliding column 11. The lower surface of the sliding column 11 is fixedly connected to the upper surface of the base 1. The outer wall of the sliding column 11 is slidably connected to the stamping plate 12. The lower surface of the stamping plate 12 is fixedly connected to the upper stamping block 13. The inner wall of the upper stamping block 13 is threadedly connected to the first throttle 14. The outer wall of the first throttle 14 is slidably connected to the inclined block 15. The outer wall of the inclined block 15 is slidably connected to the clamping block 16. The lower surface of the clamping block 16 is slidably connected to the upper surface of the upper stamping block 13. The outer wall of the clamping block 16 is slidably connected to the stamping head 17. The outer wall of the stamping head 17 is slidably connected to the inner wall of the upper stamping block 13.

[0026] Specifically, the starting motor 3 drives the worm gear 4 to rotate, which in turn drives the worm wheel 5 to rotate. The rotation of the worm wheel 5 drives the first gear 6 and the second gear 7 to rotate synchronously. The lower stamping block 2 can limit the rotation of the first gear 6 and the second gear 7 to maintain their stable rotation. The rotation of the second gear 7 drives the telescopic plate 8 to rotate, causing the cleaning brush 9 to slide horizontally. When the cleaning brush 9 slides horizontally, it cleans the waste residue on the upper surface of the lower stamping block 2. The waste residue is collected and processed by the grooves opened in the base 1 and the inner wall of the lower stamping block 2, thereby cleaning the surface of the stamping table and reducing the impact of waste on the stamping accuracy. The limiting plate 10 can control the stamping material during the stamping process. Limiting is implemented to prevent the stamping material from moving or misaligning during the stamping process, and to prevent the stamping force from damaging the unstamped material. By rotating the first handle 14, the inclined block 15 slides vertically. At this time, the spring pushes the inclined block 15 to slide vertically, causing the clamping block 16 to slide horizontally. At this time, the distance between the clamping block 16 and the upper stamping block 13 will increase, so that the stamping head 17 can be removed, which facilitates the periodic replacement of the stamping head 17 and achieves the effect of quick installation and removal of the stamping head 17. After the stamping head 17 is installed, it slides on the outer wall of the slide column 11 through the stamping plate 12. At this time, the stamping head 17 will stamp the raw material to achieve the effect of processing the raw material.

[0027] Reference Figure 1 and Figure 4 The lower surface of the base 1 is fixedly connected to an upper fixing block 25. The inner wall of the upper fixing block 25 is rotatably connected to a second handle 18. The outer wall of the second handle 18 is fixedly connected to a first semicircular plate 19. The outer wall of the first semicircular plate 19 is rotatably connected to a first locking plate 20. The outer wall of the first locking plate 20 is slidably connected to a second semicircular plate 21.

[0028] Specifically, by rotating the second handle 18 on the inner wall of the upper fixed block 25, the first semicircular plate 19 is driven to rotate. The rotation of the first semicircular plate 19 drives the first locking plate 20 to rotate. At this time, the first locking plate 20 will drive the second semicircular plate 21 to rotate. At this time, the first locking plate 20 will disengage from the second semicircular plate 21, thereby achieving the effect of quick disassembly.

[0029] Reference Figure 1 and Figure 4 The inner wall of the second semicircular plate 21 is rotatably connected to a lower fixing block 26, and the outer wall of the lower fixing block 26 is fixedly connected to a storage box 23. The upper surface of the storage box 23 is slidably connected to the lower surface of the base 1. The inner wall of the lower fixing block 26 is fixedly connected to a limit spring 22, and the outer wall of the limit spring 22 is fixedly connected to the outer wall of the second semicircular plate 21. The outer wall of the second semicircular plate 21 is rotatably connected to a second locking plate 24, and the outer wall of the second locking plate 24 is slidably connected to the inner wall of the first semicircular plate 19.

[0030] Specifically, the lower fixing block 26 can limit the rotation of the second semicircular plate 21 to maintain its stable rotation. When the second semicircular plate 21 rotates, it will stretch the limiting spring 22, thereby generating a reaction force, so that the structure springs back to its original position for easy use next time. The rotation of the second semicircular plate 21 drives the second locking plate 24 to rotate, thereby disengaging from the first semicircular plate 19. At this time, the storage box 23 can be quickly disassembled to achieve the effect of centralized processing of collected waste materials.

[0031] When the mold is needed, rotating the first throttle 14 causes the spring to push the inclined block 15 vertically. The vertical sliding of the inclined block 15 causes the clamping block 16 to slide horizontally. At this time, the distance between the clamping block 16 and the upper stamping block 13 increases, and the stamping head 17 will disengage from the upper stamping block 13, thereby achieving the effect of quick disassembly of the stamping head 17. At this time, the stamping head 17 can be replaced. After the stamping head 17 is installed, the stamping plate 12 slides on the outer wall of the slide column 11, causing the stamping head 17 to stamp the raw material. After the stamping is completed, the motor 3 is started to drive the worm gear 4 to rotate, which in turn drives the worm wheel 5 to rotate. The first gear 6 rotates, which drives the second gear 7 to rotate synchronously. The rotation of the second gear 7 drives the telescopic plate 8 to rotate, causing the cleaning brush 9 to slide horizontally. At this time, the cleaning brush 9 can clean the waste on the upper surface of the lower stamping block 2, thereby preventing the waste from affecting the stamping accuracy. To address the issue of waste collection, when a certain amount of waste is collected, the second handle 18, which rotates on the inner wall of the fixed block 25, can be rotated to drive the first semicircular plate 19 to rotate. This causes the first engaging plate 20 to drive the second semicircular plate 21 to rotate. At this time, the first semicircular plate 19 will disengage from the second semicircular plate 21. The lower fixed block 26 can limit the rotation of the second semicircular plate 21 to maintain its stable rotation. When the second semicircular plate 21 rotates, it drives the second engaging plate 24 to rotate, thereby disengaging from the first semicircular plate 19. At this time, the storage box 23 can be removed, thus achieving the effect of quick disassembly and installation of the storage box 23, which is convenient for waste collection and processing. When using this mold, the waste on the mold surface can be cleaned, thereby reducing the impact of waste on stamping accuracy. At the same time, the waste box can be quickly installed and disassembled, achieving the effect of centralized waste processing.

[0032] 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.
