[0002] A stamping die is a key process in cold stamping processing, which is used to apply pressure to a metal or non-metal sheet through a press at room temperature to cause separation or plastic deformation, so as to form parts or semi-finished products of the required shape. This process is widely used in many industries such as automobiles, electronics, and household appliances, and is favored because of its high efficiency, precision, and cost-effectiveness. The design of a stamping die needs to consider the specific requirements of the product, and its structure is diverse to adapt to different types of stamping processes to ensure the production of high-quality products that meet the specifications.

[0003] In the prior art, metal sheet stamping dies usually adopt a bolt fixing method to keep each component stable and ensure the accuracy and stability of the stamping process. However, this design makes the die replacement process more cumbersome, and it is necessary to loosen and re-tighten the bolts one by one. Especially in the case of frequently replacing different die types or specifications, the production efficiency will be significantly reduced.

[0004] In view of the above problems, a rapid replacement structure for a metal sheet stamping die is proposed to solve the above problems. Content of the Utility Model

[0023] 2. In the utility model, when the shock-absorbing plate moves upward, the moving rod slides upward on the outside of the connecting rod. At this time, the second spring is compressed. The upward movement of the moving rod causes the rotating shaft to rotate, thereby pushing the slider to slide inside the hollow plate, thereby squeezing the third spring until the upper mold and the lower mold are completely fitted, reducing the wear of the mold, realizing a tight and stable connection between the molds, not only effectively reducing the wear of the mold during the working process, but also improving the stability of the production process and the quality consistency of the products. At the same time, by reducing wear, the service life of the mold is prolonged. Description of the Drawings

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 4 As shown in the figure, an embodiment provided by the present invention: A rapid replacement structure for a metal sheet stamping mold includes two molds 7. Two connecting blocks 9 are fixedly connected to the outside of the mold 7. The outside of the connecting block 9 is slidably connected to a mounting seat 6. Two push rods 11 are slidably connected inside the mounting seat 6. A push plate 12 is fixedly connected to the outside of the push rod 11. An inserting rod 15 is slidably connected inside the connecting block 9. A

[13] is provided between the inserting rod 15 and the push plate 12. A second sliding rod 17 is slidably connected inside the push rod 11. A first spring 16 is sleeved on the outside of the second sliding rod 17. One end of the second sliding rod 17 away from the push plate 12 is fixedly connected to a connecting block 18. A plurality of limiting rods 14 are fixedly connected to the inner wall of the mounting seat 6. The bottom of the lower mounting seat 6 is fixedly connected to a base 1.

The top of the support rod 2 is fixedly connected to a top seat 4. Two cylinders 5 are fixedly connected to the bottom of the top seat 4. The output end of the cylinder 5 is fixedly connected to the top of the upper mounting seat 6. Two connecting plates 8 are fixedly connected to the outside of the upper mounting seat 6.

[0032] It should be noted that there seems to be a missing description marked as

[13] in the text you provided. If this is an important part, please check and correct it for a more accurate translation.Specifically, during use, pour the metal sheet injection liquid into the cavity of the lower mold 7. Drive the cylinder 5 to drive structures such as the upper mounting seat 6, the shock absorption mechanism, and the upper mold 7 to move downward under the guidance of the first sliding rod 3 until the upper mold 7 and the lower mold 7 are completely fitted. At the same time, under the action of the shock absorption mechanism, the wear of the mold 7 is reduced. After the metal sheet injection liquid in the cavity of the lower mold 7 cools and solidifies, take out the new metal sheet. Then, the cylinder 5 drives structures such as the upper mounting seat 6, the shock absorption mechanism, and the upper mold 7 to move back upward under the guidance of the first sliding rod 3. When the mold 7 needs to be disassembled, at this time, push the push rod 11 to move inward on the outside of the second sliding rod 17, so that the push plate 12 also moves inward, thereby compressing the first spring 16. At the same time, make 13 rotate, thereby driving the insertion rod 15 to pull the insertion rod 15 out of the inside of the connection block 9 under the limit of the limit rod 14. At this time, the mold 7 can be taken out to complete the disassembly. When installation is required, just operate in the reverse direction.

[0033] Refer to Figure 4 , the shock absorption mechanism includes a hollow plate 10 and two connecting rods 22. A second spring 21 is sleeved on the outside of the connecting rod 22. A moving rod 20 is slidably connected to the outside of the second spring 21. A shock absorption plate 19 is fixedly connected to the bottom of the moving rod 20. Two sliders 24 are slidably connected to the inside of the hollow plate 10. Two rotating shafts 23 are arranged between the slider 24 and the moving rod 20. A third spring 25 is fixedly connected between the two sliders 24.

[0034] Specifically, when the shock absorption plate 19 in the shock absorption mechanism contacts the base 1, at this time, under the huge stamping force, the shock absorption plate 19 moves upward, so that the moving rod 20 slides upward on the outside of the connecting rod 22. At this time, the second spring 21 is compressed. The upward movement of the moving rod 20 causes the rotating shaft 23 to rotate, thereby pushing the slider 24 to slide inside the hollow plate 10, thereby squeezing the third spring 25 until the upper mold 7 and the lower mold 7 are completely fitted, reducing the wear of the mold 7.

[0035] Refer to Figure 1 - Figure 4 , the bottom end of the connecting block 18 is fixedly connected to the inner bottom wall of the mounting seat 6. The inside of the insertion rod 15 is slidably connected to the outside of the limit rod 14. One end of the second spring 21 is fixedly connected to the outside of the moving rod 20. The other end of the second spring 21 is fixedly connected to one side of the connecting plate 8. One end of the first spring 16 is fixedly connected to the outside of the push plate 12. The other end of the first spring 16 is fixedly connected to the outside of the connecting block 18. One end of 13 is rotatably connected to one side of the insertion rod 15. The other end of 13 is rotatably connected to one side of the push plate 12. The top of the first sliding rod 3 is fixedly connected to the bottom of the top seat 4. The inside of the connecting plate 8 is slidably connected to the outside of the first sliding rod 3. One end of the rotating shaft 23 is rotatably connected to the outside of the moving rod 20. The other end of the rotating shaft 23 is rotatably connected to one side of the slider 24.

[0036] Specifically, the connecting block 18, as a connecting piece, is located on the inner bottom wall of the mounting seat 6 to compress the first spring 16. The insertion rod 15 slides inside the outer side of the limiting rod 14 to limit the movement of the insertion rod 15 and enable it to be accurately inserted into the connecting block 9. One end of the second spring 21 is fixed to the outer side of the moving rod 20, and the other end is connected to one side of the connecting plate 8. Its function is to provide an elastic force to assist the shock-absorbing plate 19 in buffering when encountering an impact and reduce the wear on the mold 7. One end of the first spring 16 is fixed to the outer side of the push plate 12, and the other end is connected to the outer side of the connecting block 18. Its main function is to provide the required force when disassembling the mold 7, enabling the system to smoothly disconnect and facilitating the disassembly and installation of the mold 7. One end of the connecting piece 13 is rotatably connected to one side of the insertion rod 15, and the other end is connected to one side of the push plate 12. Through the rotational movement, it plays a key transmission role and is an important link in realizing the rapid disassembly and assembly of the mold 7. The top of the first sliding rod 3 is fixedly connected to the bottom of the top seat 4, providing a guiding path for the vertical movement of the entire system and ensuring the accurate movement of the upper mold 7 in the vertical direction. The inside of the connecting plate 8 is slidably connected to the outer side of the first sliding rod 3. In this way, the connecting plate 8 can move smoothly in the vertical direction and participate in the entire operation process together with the upper mounting seat 6. One end of the rotating shaft 23 is rotatably connected to the outer side of the moving rod 20, and the other end is connected to one side of the slider 24. This design enables the up and down movement of the moving rod 20 to drive the slider 24 to slide inside the hollow plate 10, further reducing the wear of the mold 7 caused by stamping.

[0037] Working principle: During the operation, first, the metal sheet injection liquid is filled into the mold cavity of the lower mold 7. Subsequently, by starting the cylinder 5, components such as the upper mounting seat 6, the shock-absorbing mechanism, and the upper mold 7 are driven to slowly descend under the guidance of the first sliding rod 3. When the shock-absorbing plate 19 in the shock-absorbing mechanism touches the base 1, the shock-absorbing plate 19 moves upward, driving the moving rod 20 to slide upward along the outer side of the connecting rod 22. At this time, the second spring 21 is compressed. The upward movement of the moving rod 20 causes the rotating shaft 23 to rotate, thereby driving the slider 24 to slide inside the hollow plate 10 and simultaneously compressing the third spring 25 until the upper mold 7 is completely fitted with the lower mold 7. After the metal sheet injection liquid in the lower mold 7 cools and solidifies, a new metal sheet can be taken out. At this time, the cylinder 5 drives the above structure to rise along the guidance of the first sliding rod 3 to the original position. If it is necessary to disassemble the mold 7, the push rod 11 can be manually pushed to move inward outside the second sliding rod 17, driving the push plate 12 to move inward synchronously, compressing the first spring 16, and causing the connecting piece 13 to rotate, thereby pulling out the insertion rod 15. Under the restriction of the limiting rod 14, the insertion rod 15 disengages from the inside of the connecting block 9, completing the disassembly of the mold 7. When reassembling, just perform the above steps in reverse.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
