Description

Technical Field

[0001] This utility model relates to the field of forming molds, and in particular to a double-sided rotary bending die mechanism with reset function. Background Technology

[0002] In the mold manufacturing industry, with the continuous improvement of the precision and production efficiency requirements of industrial products, traditional mold structures face numerous challenges. Especially when dealing with complex bending and forming processes, the lower die forming core structure with a side-push mechanism and spring return not only occupies a large space but also carries the risk of spring return failure during high-speed stamping, leading to deviations in product dimensional accuracy. Simultaneously, under traditional forming methods, the surface of parts is easily scratched by the forming components, severely affecting the product's appearance quality. Furthermore, for special products with limited space, conventional slide block forming structures are difficult to apply, and mold development and maintenance costs remain high. These technical bottlenecks have prompted the industry to continuously explore more efficient, reliable, and economical mold solutions. Utility Model Content

[0003] The purpose of this invention is to provide a double-sided rotary bending die mechanism with reset function in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A double-sided rotary bending die mechanism with reset includes an upper die assembly, a lower die assembly, and a rotary bending mechanism. The rotary bending mechanism is disposed between the upper die assembly and the lower die assembly. The rotary bending mechanism includes a punch, forming swing blocks, pins, and a stripper core. Two punches are provided and symmetrically arranged. The top of the punch is connected to the upper die assembly. A stripper core is provided on the outer side of the punch. The bottom of the stripper core is fixed to the lower die assembly. Two forming swing blocks are correspondingly arranged on the inner side of the punch. The forming swing blocks are connected to the lower die assembly through pins. A lower die forming core is disposed between the two forming swing blocks. The bottom of the lower die forming core is connected to a lower die core.

[0006] Preferably, the upper mold assembly includes an upper mold base, an upper fixing plate pad, an upper fixing plate, and a stripper plate pad. The bottom of the upper mold base is connected to the upper fixing plate pad, the bottom of the upper fixing plate pad is connected to the upper fixing plate, and the bottom of the upper fixing plate is connected to the stripper plate pad.

[0007] Preferably, the lower mold assembly includes a stripper plate, a lower mold core plate, a lower mold core pad, and a lower mold base. The lower mold base is located at the bottom, the upper end of the lower mold base is connected to the lower mold core pad, the upper end of the lower mold core pad is connected to the lower mold core plate, and the upper end of the lower mold core plate is connected to the stripper plate.

[0008] Preferably, the forming swing block has an L-shaped structure, and the bent part of the forming swing block is rotatably connected to the stripper plate through the pin.

[0009] Preferably, the punch forms a limiting groove that matches the position of the forming swing block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. If a traditional mold structure is used, the lower mold forming core adopts a side-push mechanism, which requires spring reset. Moreover, the side-push mechanism occupies a large space. This solution cleverly uses a punch to force reset the lower mold forming core, reducing the situation where the spring cannot be reset properly during high-speed stamping. In addition, the rotary bending can reduce the scratching of the formed parts on the product surface, improving the surface quality of the product. This rotary bending mechanism is simple and compact, suitable for products that cannot be formed by a small slider, and reduces mold costs.

[0012] 2. This solution has wide applications and can be widely used for similar 180° bends or negative angle bends. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6As shown, a double-sided rotary bending die mechanism with reset includes an upper die assembly, a lower die assembly, and a rotary bending mechanism. The rotary bending mechanism is disposed between the upper die assembly and the lower die assembly.

The bottom of the stripper core 12 is fixed to the lower die assembly. Two forming swing blocks 10 are correspondingly provided on the inner side of the punch 9. The forming swing blocks 10 are connected to the lower die assembly through the pin 11. The lower die forming core 14 is provided between the two forming swing blocks 10. The bottom of the lower die forming core 14 is connected to the lower die core 13.

[0026] Preferably, the upper mold assembly includes an upper mold base 1, an upper fixing plate pad 2, an upper fixing plate 3, and a stripper plate pad 4. The upper mold base 1 is connected to the upper fixing plate pad 2 at its bottom, the upper fixing plate pad 2 is connected to the upper fixing plate 3 at its bottom, and the upper fixing plate 3 is connected to the stripper plate pad 4 at its bottom.

[0027] Preferably, the lower mold assembly includes a stripper plate 5, a lower mold core plate 6, a lower mold core pad 7, and a lower mold base 8. The lower mold base 8 is located at the bottom, and the upper end of the lower mold base 8 is connected to the lower mold core pad 7.

[0030] Working principle: When the mold is closed, the forming swing block 10 rotates around the pin 11 under the downward action of the punch 9, so that the forming part at its head applies a lateral force to the part 15. The part 15 completes a 180° rotation and bending around the forming core 14 of the lower mold. When the mold is opened, the forming swing block 10 rotates around the pin 11 under the upward action of the punch 9, opens the forming part at its head and detaches from the product, thus completing the stripping.
