The first guide rod 7 passes through the guide ring 8, and the outer wall of the first guide rod 7 is slidably connected to the guide ring 8.

[0026] The bottom mold base 15 is fixedly installed in the middle of the upper outer surface of the base plate 1. The slope 16 is formed on the outer wall of the upper part of the bottom mold base 15. The annular cutting blade 17 is fixedly installed on the upper outer surface of the bottom mold base 15. The mounting holes 18 are formed on the left and right sides of the bottom of the mold cavity of the bottom mold base 15. The second compression spring 19 is located in the mounting hole 18. The lower end of the ejector pin 20 extends into the mounting hole 18. The second compression spring 19 is fixedly installed between the lower outer surface of the ejector pin 20 and the bottom of the mounting hole 18. The outer wall of the ejector pin 20 and the mounting hole 18 are slidably connected. The lower outer surface of the ejector pin 20 is elastically connected to the bottom of the mounting hole 18 through the second compression spring 19. The mounting groove 10 is formed on the lower outer surface of the top mold base 9. The second guide rod 1 Both the first compression spring 14 and the second guide rod 13 are located in the mounting groove 10. The upper outer surface of the second guide rod 13 is fixedly connected to the middle of the upper end of the mounting groove 10. The first compression spring 14 is movably sleeved on the outer wall of the second guide rod 13. The guide groove 12 is opened in the middle of the upper outer surface of the pre-pressing block 11. The lower end of the second guide rod 13 extends into the upper part of the guide groove 12.

[0027] It should be noted that this utility model is a device for trimming the outer edge of a square tantalum capacitor shell. The blank is placed on the upper outer surface of the bottom mold assembly 4. The top mold assembly 5 is lowered by the hydraulic rod 6. The top mold assembly 5 drives the first guide rod 7 to slide along the guide ring 8, which can improve the stability of the lifting and lowering of the top mold assembly 5. After the mold is closed between the top mold base 9 and the bottom mold base 15, the square tantalum capacitor shell is stamped and formed. The edge is trimmed by the set annular trimming knife 17. The scrap edge after trimming will extend to the upper part of the slope 16. The set slope 16 facilitates the unloading of scrap material. When the top mold base 9 descends, the pre-pressing block 11 is in pre-contact with the workpiece to improve the stability of the workpiece during stamping and avoid the workpiece from collapsing during stamping. When the workpiece is stamped, the pre-compression block 11 presses the first compression spring 14 along the mounting groove 10. When the workpiece is stamped, the ejector pin 20 is pressed into the mounting hole 18. The ejector pin 20 presses the second compression spring 19 in the mounting hole 18. After the stamping is completed, the hydraulic rod 6 drives the top mold base 9 to rise. Due to the reset action of the first compression spring 14, the pre-compression block 11 is reset, preventing the workpiece inside the bottom mold base 15 from rising together with the top mold assembly 5, and preventing the workpiece from covering the outer wall of the lower part of the top mold base 9. After the mold is separated, due to the reset action of the second compression spring 19, the ejector pin 20 is reset. The ejector pin 20 pushes out part of the workpiece inside the bottom mold base 15, making it easier to remove and unload the workpiece.
