Detailed implementation method:

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 4As shown, a stamping die for a signboard part includes an upper die plate 1 and a lower die plate 2. A die handle 3 is installed at the center of the top wall of the upper die plate 1. A pad 4 is installed on the bottom wall of the upper die plate 1. An upper stamping die 5 is installed on the bottom wall of the pad 4. A stamping groove 6 is formed on the bottom wall of the upper stamping die 5. A punch 7 is vertically installed downward on the top wall of the stamping groove 6. A pair of guide sleeves 8 are installed on the bottom wall of the upper die plate 1. A guide post 9 is slidably connected inside the guide sleeves 8. The bottom end of the guide post 9 is fixedly connected to the top wall of the lower die plate 2. A lower punch 10 is installed on the top wall of the template 2. Several rubber springs 11 are evenly arranged around the lower punch 10. The bottom end of the rubber spring 11 is connected to the top wall of the lower template 2, and the top end of the rubber spring 11 is connected to the bottom wall of the unloading plate 12. A punching through groove 13 matching the lower punch 10 is provided on the unloading plate 12. A blanking through hole 14 matching the punch 7 is provided on the lower punch 10. An unloading assembly is provided on the upper template 1, and a feeding positioning assembly is provided on the unloading plate 12.

[0019] Specifically, signboards can be produced quickly using specialized stamping dies at a low cost.

[0020] In actual use, the operator first moves the upper template 1 and lower template 2 from the assembly onto the stamping machine and fixes the lower template 2 on the stamping machine's worktable. Then, the die shank 3 is connected and fixed to the slider mechanism on the stamping machine. After the upper template 1 and lower template 2 are precisely installed on the stamping machine, the long strip of material 21 is placed on the unloading plate 12. Guided by the feeding and positioning components, the material 21 moves horizontally. At this time, the starting stamping machine drives the upper template 1 downwards, the guide column 9 slides within the guide sleeve 8, and the upper stamping die 5 stamps the material 21, simultaneously receiving the impact... As the pressure stripper plate 12 descends, the lower punch 10 extends from the punching slot 13. After the lower punch 10 is inserted into the punching groove 6, the marking plate is also punched out. During this process, the punch 7 simultaneously punches out round holes on the marking plate, and the punched round scrap naturally falls from the discharge hole 14 into the scrap collection box below. During the return stroke, under the upward push of the rubber spring 11, the stripper plate 12 returns to the same plane as the top of the lower punch 10. Since the connection and fixing of the mold and the stamping machine are existing technologies, they will not be described in detail here.

[0021] like Figures 1 to 4As shown, a stamping die for a signboard part includes an ejector rod 15. A through groove is coaxially formed on the die handle 3 and the pad 4, communicating with the inner cavity of the stamping groove 6. The ejector rod 15 is slidably connected to the through groove. A top piece 16 is fitted within the stamping groove 6, and a through hole is formed on the top piece 16. The punch 7 extends through the through hole to the outside of the top piece 16. The feeding and positioning assembly includes two guide pins 17 arranged side-by-side. A positioning pin 18 is provided on one side of the guide pin 17. Both the guide pin 17 and the positioning pin 18 are vertically mounted on the top wall of the unloading plate 12. A blind hole matching the guide pin 17 and the positioning pin 18 is opened on the bottom wall of the upper stamping die 5. An insertion hole 19 is opened on the upper template 1. The guide sleeve 8 is installed in the insertion hole 19. Screws 20 are screwed at the four corners of the upper template 1 and the lower template 2. The lower stamping punch 10 is U-shaped.

[0022] Specifically, the stamped signboard can be quickly ejected via the unloading assembly.

[0023] In actual use, the cut-out signboard will remain temporarily in the stamping groove 6. When the upper template 1 returns after stamping, the ejector bar in the upper slider mechanism of the stamping machine will strike the ejector bar 15. The ejector bar 15 slides downward in the through groove and strikes the top block 16 installed in the stamping groove 6. There is a gap between the stamping groove 6 and the top block 16, which allows the top block 16 to move downward and push the signboard out of the stamping groove 6. When the stamping machine stamps again, the ejector bar 15 returns to its original position. The two guide pins 17 form a straight line, allowing the material plate 21 to move horizontally and preventing it from shifting. When the material plate 21 is stamped with a convex notch, the worker lifts the material plate 21 and places the convex notch on the positioning pin 18, so that the complete surface of the material plate 21 is directly below the stamping. This minimizes the waste generated by the material plate 21 after continuous stamping and makes it neater. The screw 20 is screwed onto the upper template 1 and the lower template 2, which facilitates the quick handling and unloading of the entire mold.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
