Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die that facilitates the replacement of die slots. Background Technology

[0002] In the complex and precise production process of stamping, the diversity of products determines the complexity of the forming process. Because various products differ greatly in shape, size, and precision requirements, the die grooves of the stamping dies must be specifically adapted accordingly. Take common sheet metal stamping parts as an example: for manufacturing large, complex curved parts like automotive body panels, a large die groove with precise curvature is needed to ensure the sheet metal accurately fits the design contour, achieving a smooth, seamless forming effect. On the other hand, for metal casings of small electronic components, which are tiny and require strict control over edge and corner precision, the corresponding die groove must not only be small in size but also have delicate edge treatment and ultra-high tolerance precision to stamp casings that meet assembly standards. In short, only by matching die grooves of different shapes and specifications can stamping overcome numerous difficulties and successfully transform raw materials into precisely formed products that meet expectations.

[0003] Traditional stamping dies typically connect their die slots to the die base using complex methods such as bolting and welding. When a die slot needs to be replaced, workers must spend a significant amount of time disassembling the bolts and cleaning the connection points. If the die slot is welded, specialized equipment is required for cutting and separating it before installing the new die slot and recalibrating its position. This entire process is extremely complex, increasing not only the labor intensity of workers but also extending equipment downtime, reducing production efficiency, and increasing production costs. Therefore, a stamping die with a die slot that is easy to replace is proposed. Utility Model Content

[0025] Example

[0026] In existing technologies, the process of changing the die slot in traditional stamping dies is cumbersome and time-consuming, which affects production efficiency.

[0027] Please see Figures 1-5This utility model provides a technical solution: a stamping die that facilitates die slot replacement, including a stamping table 11, a lower die base 12 fixedly connected to the middle of the upper surface of the stamping table 11, a die slot seat 13 slidably connected to the inner side wall of the lower die base 12, limit grooves 14 formed on both sides of the inner side wall of the lower die base 12, limit sliders 15 fixedly connected to both sides of the die slot seat 13, the outer side wall of the limit sliders 15 slidably connected to the inner side wall of the limit grooves 14, a rotating shaft 16 penetrating both sides of the front surface of the lower die base 12, a plurality of limit blocks 17 welded to the outer side wall of the rotating shafts 16, and the limit sliders 15... Multiple limiting slots 18 are provided on the side of the upper surface away from the mold base 13. The outer side wall of the limiting block 17 is slidably connected to the inner side wall of the limiting slot 18 on the side away from the rotating shaft 16. Multiple fan-shaped slots 19 are provided on the side of the inner side wall of the two limiting slides 14 that are far apart. The outer side wall of the limiting block 17 is rotatably connected to the inner side wall of the fan-shaped slot 19. The front part of the outer side wall of the rotating shaft 16 is fixedly connected to the limiting component 2. The limiting sliders 15 on both sides of the mold base 13 slide inside the limiting slides 14, thereby limiting the limiting sliders 15 and increasing the stability of the mold base 13.

[0028] In one embodiment, the limiting component 2 specifically includes a connecting arm 20, a plug rod 21, a limiting ring 22, a limiting cylinder 23, a reset spring 24, and a first insertion hole 25;

[0029] A connecting arm 20 is fixedly connected to the front part of the outer side wall of the rotating shaft 16. A rod 21 passes through the front surface of the connecting arm 20 away from the rotating shaft 16. A limiting ring 22 is fixedly connected to the middle of the outer side wall of the rod 21.

The outer side wall of the limiting ring 22 is slidably connected to the inner side wall of the limiting cylinder 23. The front surface of the rod 21 passes through the center of the inner front wall of the limiting cylinder 23. A return spring 24 is sleeved on the outer side wall of the rod 21 near the front of the limiting ring 22. The front surface of the return spring 24 is attached to the inner front wall of the limiting cylinder 23 near the outer side of the insertion rod 21, and the rear surface of the return spring 24 is attached to the front surface of the limiting ring 22 near the outer side of the insertion rod 21. The front surface of the limiting slider 15 has a first insertion hole 25. The rear part of the outer side wall of the insertion rod 21 is attached to the inner side wall of the first insertion hole 25. The insertion rod 21 is inserted into the first insertion hole 25, thereby limiting the connecting arm 20, thereby limiting the rotating shaft 16, and at the same time helping to limit the limiting slider 15.

[0030] In one embodiment, specifically, an L-shaped bracket 26 is welded to the middle of the rear surface of the stamping table 11. A mounting hole 27 is opened at the front of the upper surface of the L-shaped bracket 26. A stamping cylinder 28 is fixedly connected to the inner side wall of the mounting hole 27. An upper die base 29 is fixedly connected to the output end of the stamping cylinder 28. A stamping die head 30 is installed in the middle of the lower surface of the upper die base 29. The upper die base 29 is pushed up and down by the stamping cylinder 28, thereby driving the stamping die head 30 to move up and down and cooperate with the die slot seat 13 to perform stamping operation.

[0031] In one embodiment, a positioning groove 31 is provided in the middle of the inner rear wall of the lower mold base 12, and a positioning block 32 is fixedly connected to the middle of the rear surface of the mold base 13. The outer side wall of the positioning block 32 is slidably connected to the inner side wall of the positioning groove 31. By inserting the positioning block 32 at the rear of the mold base 13 into the positioning groove 31, the mold base 13 is limited.

[0032] In one embodiment, specifically, the front surface of the lower mold base 12 is provided with second insertion holes 33 on both sides near the upper part of the rotating shaft 16. By inserting the insertion rod 21 into the second insertion hole 33, the rotating shaft 16 is limited, thereby preventing the rotating shaft 16 from rotating accidentally when the push-pull mold slot base 13 is installed or disassembled.

[0033] In one embodiment, a pull button 34 is fixedly connected to the front surface of the insertion rod 21, which facilitates pulling the insertion rod 21.

[0034] In one embodiment, specifically, buffer pads 35 are fixedly connected to the four corners of the lower surface of the stamping table 11. The buffer pads 35 provide buffer protection for the stamping table 11, thereby improving the service life of the stamping table 11.

[0035] In one embodiment, a plurality of stamping die grooves 36 are provided in the middle of the upper surface of the die groove base 13, and a push-pull groove 37 is provided at the center of the front part of the upper surface of the die groove base 13, so that the die groove base 13 can be pushed and pulled to disassemble and assemble.

[0036] Working principle or structural principle: When replacing the mold slot seat 13, pulling the button 34 moves the insertion rod 21 forward. The insertion rod 21 drives the limiting ring 22 to slide forward within the limiting cylinder 23 and compress the return spring 24, causing the insertion rod 21 to disengage from the first insertion hole 25 and releasing the limitation on the limiting slider 15. Then, the rotating shaft 16 is rotated, causing the limiting block 17 to rotate within the sector groove 19, causing the limiting block 17 to disengage from the limiting groove 18. The rotated shaft 16 then drives the connecting arm 20 to rotate, aligning the insertion rod 21 with the second insertion hole 33 on the lower mold seat 12. Releasing the button 34 allows the insertion rod 21 to insert into the second insertion hole 33 under the elastic force of the return spring 24, thus limiting and fixing the rotating shaft 16. Then, the mold slot seat 13 is pulled forward through the push-pull groove 37, causing the mold slot seat 13 to move the limiting slider 15 within the limiting groove 23. The mold slot seat 13 is slid forward within the sliding groove 14 to remove it from the lower mold base 12, thus achieving the purpose of quickly replacing the mold slot seat 13. When installing a new mold slot seat 13, the positioning block 32 behind the mold slot seat 13 is aligned with the positioning groove 31 in the middle of the rear wall of the lower mold base 12. The mold slot seat 13 is pushed backward, causing the limiting slider 15 to slide into the limiting groove 14. When the limiting slot 18 on the limiting slider 15 corresponds to the position of the limiting block 17, the pull button 34 is pulled to separate the insertion rod 21 from the second insertion hole 33. The rotating shaft 16 is rotated to make the limiting block 17 engage in the limiting slot 18, thus limiting the mold slot seat 13. At the same time, the pull button 34 is released, and the elastic force of the return spring 24 causes the insertion rod 21 to move backward and insert into the first insertion hole 25, thereby limiting the rotating shaft 16 and further fixing the mold slot seat 13.

[0037] In summary, this utility model achieves rapid installation and disassembly of the mold slot base 13 by slidingly connecting the lower mold base 12 and the mold slot base 13 through the limiting slide groove 14 and the limiting slider 15, and by cooperating with the limiting block 17, the limiting slot 18, and the rotation limiting of the sector groove 19. This eliminates the need for complex bolt fixing or welding, simplifies the mold slot replacement operation process, effectively improves the efficiency of mold slot replacement, reduces the labor intensity of workers, reduces equipment downtime, improves production efficiency, and reduces production costs.
