Description

Technical Field

[0001] This utility model relates to the field of hardware processing mold technology, and more specifically, to a side-push rivet mold. Background Technology

[0002] In stamping assembly processes, rivets are a common connection method, typically used to press straight rivets into product holes to achieve a secure connection between structural components.

[0003] The applicant's prior patent, such as utility model patent number CN202222216144.3, discloses a metal processing mold for removing nails, including an upper mold assembly and a lower mold assembly. The upper mold assembly is provided with a vertically downward nail head for applying pressure to the nail during vertical downward stamping. The lower mold assembly is provided with an elastic ejector assembly directly opposite the nail head for ejecting the product after stamping, thus achieving the removal operation. This type of metal processing mold can effectively complete the nailing task when processing plate-shaped products; however, it is not suitable for processing U-shaped structures or box-like structures with one open end. When performing nailing operations on such products, it is usually necessary to place the product vertically (i.e., the two side walls are arranged horizontally up and down), place the nail on the lower side wall inside the product, and then perform nailing. However, the nail head in the processing mold of the prior application is a vertically downward pressing structure, which requires applying pressure to the nail from directly above. Due to the presence of the upper sidewall of the product, the nail head will be interfered with during the downward pressing process, and will be unable to complete the nailing operation on the nail on the lower sidewall normally, resulting in the mold being unusable or the operation failing.

[0004] Therefore, there is an urgent need for a mold structure capable of laterally pushing rivets to solve the interference problem when handling U-shaped or one-end-open box-shaped products, thereby improving the flexibility and applicability of rivet operation. This utility model addresses the aforementioned technical problems by proposing a lateral-push rivet mold, which has significant practical value and innovative significance. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] A preferred embodiment of this utility model provides a side-push rivet mold, which is suitable for products with a U-shaped structure or a box-like structure with one open end; such as Figure 1-2 As shown, it includes an upper mold assembly 10 and a lower mold assembly 20. The lower mold assembly 20 is provided with a pin position 21 for placing the product. A pin assembly 22 is slidably disposed on the lower mold assembly 20, and an elastic guide assembly 23 guides the pin assembly 22 to move laterally toward the pin position 21.

[0026] The elastic guide component 23 ensures that the pin assembly can move smoothly and accurately to the pin position in the correct direction.

[0027] In this embodiment, the nail assembly 22 includes a slider 221 slidably connected to the lower die assembly 20; the slider 221 has a groove 222 on the side facing the nail position 21; a pressing block 223 that can slide longitudinally is provided in the groove 222, and a first elastic element 224 (such as a vertically arranged spring) provides a vertical elastic force to the pressing block 223; at least a portion of the pressing block 223 protrudes out of the groove 222; a vertically downward nail 225 is provided at the lower end of the pressing block 223 that protrudes out of the groove 222; the upper die assembly 10 is provided with a cutting tool 11 that applies pressure to the slider 221 to move it toward the nail position 21, and a punch head 12 that applies pressure to the pressing block 223 to drive the nail 225 downward. Both the inserter 11 and the stamping head 12 are parallel columnar structures, and the lower surface of the inserter 11 is higher than the lower surface of the stamping head 12. During the mold closing process, the inserter 11 will first contact and drive the pin assembly to move, and then the stamping head 12 will contact the pressing block and perform the stamping pin operation.

[0028] The mold has a simple structure and ingenious design. When the upper and lower mold components are closed, the inserter drives the nail assembly to move laterally to the nail position. At this time, one end of the pressing block and the nail are inserted into the product and positioned above the nail position. Simultaneously, the punching head applies pressure to the other end of the pressing block, causing the nail at its bottom to move downwards and nail the side wall of the product at the nail position. This mold realizes the dual functions of lateral pushing of the nail assembly and vertical nailing of the product side wall, effectively solving the problem of nailing difficulties caused by structural interference when processing U-shaped or one-end open box-shaped products. It is easy to operate, highly applicable, and significantly improves the applicability and success rate of nailing operation.

[0029] Furthermore, the elastic guide component 23 is staggered with the inserter 11, optimizing the internal space layout of the mold and making the overall structure more compact. When the upper mold assembly and the lower mold assembly are closed, the elastic guide component 23 will not interfere with the inserter 11. A first positioning post 24 is fixedly provided on one side of the pin assembly 22 on the lower mold assembly 20. The elastic guide component 23 includes a guide rod 231 slidably connected to the first positioning post 24, and a second elastic element 232 (such as a spring in the prior art) sleeved on the guide rod 231. The first positioning post 24 is provided with a through hole 241 for the guide rod 231 to pass through. One end of the guide rod 231 is fixedly connected to the slider 221, and the other end is provided with a limiting block 233 to prevent the guide rod 231 from disengaging from the through hole 241. The structure is stable, and the guide rod 231 and the through hole 241 of the first positioning post 24 are precisely matched to ensure that the pin assembly 22 slides smoothly along a predetermined trajectory when moving laterally, avoiding deviation or shaking, and improving the accuracy of the pin position. The second elastic element 232 is disposed between the first positioning post 24 and the limiting block 233; the second elastic element can provide a buffering effect during the movement of the nail assembly 22, absorb part of the impact force, reduce the vibration caused by rapid movement or pressure applied by the stamping head 12, and protect the mold and the product.

[0030] Furthermore, the upper end of the slider 221 facing the first positioning post 24 is provided with a first inclined surface 226 that is inclined downward toward the first positioning post 24 and slides in cooperation with the inserter 11; when the upper mold assembly and the lower mold assembly are closed, the lower end of the inserter 11 slides along the first inclined surface 226, and the slider 221 is easily pushed toward the pin position by the guiding effect of the inclined surface, which improves the smoothness and stability of the mold action.

[0031] Furthermore, the inserter 11 is provided with a second inclined surface 111 parallel to the first inclined surface 226, and a vertical contact surface 112 that fits and engages with the side surface of the first positioning post 24 facing the slider 221. This can effectively prevent the inserter 11 from deflecting due to lateral force during movement, thereby improving the accuracy and stability of the inclined surface engagement between the inserter and the slider, and ensuring the accuracy of the nailing action.

[0032] Optionally, the first elastic element 224 is vertically disposed in the slide groove 222. The lower end of the pressing block 223 is provided with a receiving groove for inserting one end of the first elastic element 224, and the inner bottom surface of the slide groove 222 is provided with a positioning groove corresponding to the receiving groove for inserting the other end of the first elastic element 224. Through the nested structure of the receiving groove and the positioning groove, the first elastic element 224 is firmly fixed in the slide groove 222, preventing it from shifting, tilting, or even falling off due to impact or vibration during the nailing process. The first elastic element 224 is well limited in the vertical direction, and its compression and rebound directions are more perpendicular, providing a uniform and stable elastic force, thereby effectively buffering the impact force during the nailing process and reducing damage to the mold and product. Furthermore, the first elastic element 224 also helps the pressing block 223 to quickly reset after nailing, improving the continuity and efficiency of mold operation.

[0033] Furthermore, the rivet position 21 is provided with multiple mounting holes 211 through which straight nails on the product pass; multiple rivets 225 are provided, and each rivet 225 corresponds to a mounting hole 211, which can complete the rivet insertion operation of multiple straight nails in one stamping action, significantly improving the rivet efficiency.

[0034] Furthermore, the lower mold assembly 20 is provided with a second positioning post 25 on one side of the pin position 21 for product positioning; the pin assembly 22 is located between the first positioning post 24 and the second positioning post 25; the second positioning post 25 and the pin assembly cooperate with each other to effectively position and support the product, which is beneficial for subsequent pinning of the side wall of the product.

[0035] Furthermore, a guide post assembly 30 is provided between the upper mold assembly 10 and the lower mold assembly 20. The guide post assembly 30 plays a guiding role during the opening and closing of the mold, ensuring that the upper mold assembly 10 and the lower mold assembly 20 can be aligned and closed in the vertical direction to avoid displacement.

[0036] During the stamping process, in order to prevent the upper and lower dies from closing too deeply and causing damage to the cutting tool and rivet assembly, a first limiting post 13 is fixedly provided on the lower surface of the upper die assembly 10; a second limiting post 26 corresponding to and abutting against the first limiting post 13 is provided on the upper surface of the lower die assembly 20; the first limiting post 13 and the second limiting post 26 form physical contact when the dies are closed, playing a "limiting" role to ensure that the upper die assembly and the lower die assembly do not close excessively in the vertical direction.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
