Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figures 2-12 As shown, a slanted punching die includes an upper die base 4 and a lower die base 3. An outer guide post 11 is provided between the upper and lower die bases to guide the punching process. An upper fixed plate 5 is fixedly connected to the bottom of the upper die base, and an upper pressure plate 6 is fixedly installed at the bottom of the upper fixed plate. An inner guide post is fixedly installed on the upper pressure plate, and an upper clamping plate 7 and an upper template 8 are connected via the inner guide post. A lower clamping plate 10 is fixedly installed on the lower die base, and a lower template 9 is fixedly installed on the lower clamping plate. Guide holes are correspondingly provided on the lower clamping plate and the lower template, corresponding to the inner guide post 12 passing through. The upper and lower templates are respectively equipped with an upper clamping plate insert 13, an upper template insert 14, and a lower template insert 15. The upper clamping plate insert is equipped with a product placement platform, and the product placement platform is equipped with an inclined platform for punching holes for the product's feet. The upper clamping plate insert and the upper template insert are respectively equipped with inclined grooves with openings at the top. A slider 23 and a pressure block 24 are slidably connected in the inclined grooves. A punch 26 is installed in the pressure block. A punch is provided in the upper template insert at the location of the punch. The punch is set on the inclined platform corresponding to the punching holes for the product's feet. The slider contacts the upper pressure plate.

[0016] A return spring 25 is provided between the upper template insert and the pressure block. Limiting holes 21 are provided on both sides of the inclined groove on the upper clamping plate insert, and corresponding limiting pins 22 are fixedly installed on the slider. The limiting pins move and limit along the limiting holes.

[0017] The upper clamping plate insert and the upper template insert are positioned by locating pins 19 and fixed by fixing bolts 20. The upper template insert is fixed to the upper clamping plate by bolts.

[0018] The lower template insert has a scrap cavity 27 corresponding to the punch on the product placement table. The lower clamping plate and the lower template have a discharge slot corresponding to the scrap cavity.

[0019] A positioning block 16 is fixedly installed on the lower clamping plate inside the lower template, and a positioning post 17 is fixedly installed on the upper end of the positioning block. The position of the positioning post corresponds to the positioning hole on the product. The positioning block is fixed and pressed onto the lower template by fastening bolts 18. A limit structure is provided between the upper template and the inner guide post.

[0020] In use, the upper and lower mold bases are opened. At this time, the upper clamping plate and the upper template are hung on the inner guide post, with a gap between the upper clamping plate and the upper pressure plate. The product is placed on the product placement table of the lower template insert, and the product positioning hole is positioned corresponding to the positioning post. The upper mold base is pressed down, which drives the upper pressure plate to press down, and the upper and lower templates close. The upper template insert clamps the product on the product placement table of the lower template insert. The upper pressure plate continues to press down, which drives the slider moving inside the upper clamping plate insert to press down. The slider drives the pressure block to press down, and the pressure block drives the punch to punch downward. The punch punches a hole on the product joint. Under the action of the stamping machine force and speed, the preset hole is punched out, and the waste material flows out along the waste material cavity of the lower mold core. When the mold is opened, the return spring releases the yield force to push the pressure block. The pressure block drives the punch and slider to move upward along the inclined groove trajectory until the position limited by the limit pin.

[0021] This invention designs a slanted punching die, specifically for processing small round holes in narrow and non-horizontal structural spaces. It effectively solves the problem of positional accuracy of round punches, simplifies the operation steps for die maintenance during production, and improves production efficiency and quality.

[0022] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
