Technical Field

[0001] This utility model relates to the field of flexible stamping technology, and in particular to multi-process flexible stamping dies. Background Technology

[0002] In traditional manufacturing, each product is produced using a separate mold. This flexible bending and forming shared mold is designed to enable multiple steps in one mold to produce multiple products, allowing for flexible and rapid switching and reducing investment costs.

[0003] Traditional molds have structural limitations. Because they are designed specifically for a particular product, each component of the mold, such as the die and punch, is customized according to the shape and size of the product. This means that when different styles of products need to be produced, the entire mold must be redesigned and manufactured. This not only consumes a lot of time and manpower, but also increases the procurement and storage costs of the mold. In addition, the adjustment and replacement process of traditional molds is complex and cumbersome, requiring professional technicians to operate, and errors are prone to occur during the adjustment process, affecting the quality stability of the product.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 This utility model provides a technical solution: a flexible stamping die, including an upper die base 1 and a lower die base 2. The bottom of the upper die base 1 is connected to an upper pad 3, and the bottom of the four corners of the upper pad 3 are connected to equal height sleeves 4. A stripper plate 5 is installed on the outside of the equal height sleeve 4, and an upper clamping plate 6 is connected to the lower part of the middle of the stripper plate 5 by a pin. A die changing mechanism is provided on the outside of the upper clamping plate 6. The top two sides of the lower die base 2 are fixedly connected to lower pad feet 7, and the top of the lower pad feet 7 is fixedly connected to a lower pad 8. A lower clamping plate 9 is installed on the upper part of the middle of the lower pad 8 by a pin, and a flexible buffer mechanism is provided below the lower clamping plate 9.

[0028] Reference Figure 3 , Figure 4The upper mold base 1 has multiple sets of connecting holes 10 on its outer side, and the lower mold base 2 has multiple sets of fixing holes 11 inside. The bottom sides of the upper pad 3 are fixedly connected to the limiting guide cylinders 12, and the limiting guide cylinders 12 pass through the stripper plate 5 and are fixed by nuts 13. Multiple sets of damping telescopic rods 14 are connected between the upper pad 3 and the stripper plate 5, and springs 15 are provided on the outer side of the damping telescopic rods 14. The damping telescopic rods 14 and springs 15 can provide buffer protection for the upper pad 3 and the stripper plate 5.

[0029] Reference Figure 1 , Figure 2 The mold changing mechanism includes an upper mold punch insert 16, a lower mold die insert 17, screws 18, and mounting grooves 19. Mounting grooves 19 are respectively opened inside the upper clamping plate 6 and the lower clamping plate 9. The upper mold punch insert 16 and the lower mold die insert 17 are respectively installed inside the mounting grooves 19 by screws 18.

[0030] In specific implementation, a flexible stamping die, when installing and changing a multi-process flexible stamping die, firstly, the upper die base 1 is installed on the stamping machine through the connecting hole 10 on the outside of the upper die base 1. Then, the lower die base 2 is fixed in the position corresponding to the upper die base 1 through the fixing hole 11 inside the lower die base 2. After installation, according to production needs, the screws 18 on the outside of the upper clamping plate 6 and the lower clamping plate 9 are rotated and removed, so that the upper die punch insert 16 and the lower die cavity insert 17 can be removed from the mounting slot 19. Then, the upper die punch insert 16 and the lower die cavity insert 17 that need to be replaced are placed in the corresponding mounting slot 19 and connected and fixed by the screws 18. This allows the die to quickly match the forming requirements of different products, and also makes the die adjustment and replacement process simpler and more convenient. In this way, by simply removing the screws 18, the die inserts of the corresponding products can be quickly switched, realizing one die for multiple processes corresponding to multiple products, flexible and fast switching, and reducing investment costs.

[0031] Example 2

[0032] Reference Figure 3 This embodiment is an optimization based on the first embodiment. Limiting blocks 26 are fixedly connected to both sides of the lower clamping plate 9, and the limiting blocks 26 are located at the top of the lower pad plate 8. The limiting blocks 26 have limiting holes 27 that match the height sleeve 4 inside. Limiting posts 20 are fixedly connected to both sides of the top of the lower mold base 2, and the limiting posts 20 are located between the two lower pad feet 7. The lower pad plate 8 has sliding holes 21 that match the limiting posts 20 inside.

[0033] Reference Figure 5The flexible buffer mechanism includes a push rod 22, a top plate 23, urethane rubber 24, and mounting holes 25. Two sets of urethane rubber 24 are installed on the top of the lower mold base 2. The urethane rubber 24 can play a role in buffering and shock absorption, effectively reducing vibration and noise during the stamping process. The top plate 23 is fixedly connected above the urethane rubber 24. The mounting groove 19 and the lower pad 8 have through mounting holes 25. The top of the top plate 23 is fixedly connected to the push rod 22. The push rod 22 matches the mounting hole 25. The push rod 22 is fitted inside the mounting hole 25, and the top of the push rod 22 is connected to the lower mold cavity insert 17.

[0034] In specific implementation, a flexible stamping die, when used in a multi-stage flexible stamping die, has an upper die base 1 connected to a stamping machine. Under the stamping of the stamping machine, the upper die base 1, the upper pad 3, and the stripper plate 5 move rapidly up and down along the inner wall of the limiting hole 27 via the equal height sleeve 4. Because multiple sets of damping telescopic rods 14 and springs 15 are connected between the upper pad 3 and the stripper plate 5, the damping telescopic rods 14 and springs 15 provide buffering protection for the stamped upper pad 3 and stripper plate 5. During the stamping process, this allows the upper die punch insert 16 to engage with the lower die recess. The die insert 17 fits tightly, thereby realizing the stamping and forming of the product. At the same time, during the pressing process of the lower die insert 17, and because the lower die insert 17 is in flexible contact with the ejector pin 22, and the ejector pin 22 is connected to the top plate 23 and the urethane rubber 24, the vibration and noise during the stamping process are effectively reduced by the buffering and shock absorption effect of the urethane rubber 24. This improves the service life of the upper die insert 16 and the lower die insert 17 and the quality of the product. Through the above operations, the mold is made universal and the production is made flexible, which significantly reduces the mold investment cost.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
