DETAILED DESCRIPTION

[0022] In order to more clearly understand the technical means of the utility model, and can be implemented according to the content of the specification, the specific embodiments of the utility model are further described in detail below, the following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0023] A stamping die with in-mold automatic riveting structure, as shown in Figures 1-5 Fig. 1, comprising an upper die holder 1 and a lower die holder 2, and a carrier 6 transported along the length direction of the lower die holder 2 and a product 5 material belt transported along the width direction of the lower die holder 2, the bottom of the upper die holder 1 is fixedly connected with an upper backing plate 11, the top of the lower die holder 2 is fixedly connected with a lower backing plate 21, the bottom of the upper backing plate 11 is provided with a stripper plate 14, the top of the lower backing plate 21 is provided with a lower die plate 22, the top of the lower die plate 22 is provided with a machining structure for machining the carrier 6, the top of the lower die plate 22 is provided with a feeding structure 10 for transporting the product 5 to the carrier 6 on the discharge side of the machining structure, and the top of the lower die plate 22 is further provided with a riveting structure for riveting the product 5 on the carrier 6 on the discharge end of the machining structure;

[0024] The top of the lower die plate 22 is fixedly connected with carrier 6 guide plates 221 arranged symmetrically, the horizontal movement track of the carrier 6 is limited by the carrier 6 guide plates 221, so that the movement of the carrier 6 is more stable, the machining structure comprises a hole assembly 7 for riveting holes in the carrier 6 and a stretching part 8 for stretching the holes, the stretching part 8 is fixedly connected to the top of the lower backing plate 21 and passes through the lower die plate 22, the top of the stretching part 8 is provided with a protruding part 81 in the shape of a circular arc, the protruding part 81 plays a good guiding role, when aligning the hole on the carrier 6, the protruding part 81 can better stretch the hole in the carrier 6 and more conveniently form a riveting column 61, a clearance groove matched with the riveting column 61 is formed on the stripper plate 14;

[0025] The riveting structure includes a riveting punch 121 located at the bottom of the upper pad 11 and a pressure block 4 located on the lower template 22. The riveting punch 121 has a protrusion at its end, and the pressure block 4 has a through hole for the protrusion to pass through. A stripper plate 14 is fixedly connected to the bottom plate of the lower template 22. A stripper block 3 is located on the stripper plate 14. The riveting punch 121 passes through the stripper block 3. A receiving groove 31 is located on the stripper block 31. A knock-out pin 32 is slidably connected in the receiving groove 31. A knock-out spring 33 is located in the receiving groove 31. The knock-out spring 33 has elastic deformation potential energy to drive the knock-out pin 32 out of the receiving groove 31. A groove is located on the lower template 22. A pressure fixing seat 41 is fixedly connected to the top of the lower pad 21 and located in the groove. The pressure block 4 is movable in the vertical direction. The lower part of the pressure block 4 is connected in the groove and located at the top of the pressure fixing seat 41. The pressure fixing seat 41 restricts the movement of the pressure block 4. When the pressure block 4 contacts the pressure fixing seat 41, the top of the pressure block 4 is flush with the top surface of the upper template. The bottom of the pressure block 4 is provided with a force transmission pin 42 that passes through the pressure fixing seat 41. The force transmission pin 42 is vertically connected to the lower mold base 2. The lower mold base 2 is provided with a slide groove that slides with the force transmission pin 42. A strong spring 421 is provided on the inner bottom wall of the slide groove. The strong spring 421 has elastic deformation potential energy to drive the force transmission pin 42 to move out of the slide groove. The top of the lower pad 21 is fixedly connected with a positioning pin 43. When the pressure fixing seat 41 abuts against the pressure block 4, the positioning pin 43 passes through the pressure fixing seat 41 and the pressure block 4.

[0026] The feeding structure 10 adopts an in-mold feeding structure 10. When the upper mold base 1 and the lower mold base 2 are close, the product 5 strip is transported in the mold, ensuring the stability of the product 5 strip transport. A cutting component 9 for cutting the product 5 is also provided between the feeding structure 10 and the riveting structure. When the product 5 is fed into the carrier 6, the product 5 strip can be cut while riveting is being performed.

[0027] Working principle: Product 5 is fed between the two product 5 guide plates. The feeding structure 10 transports the product 5 strip along the width direction of the lower mold base 2. The carrier 6 is fed between the two carrier 6 guide plates 221. The upper mold base 1 is brought close to the lower mold base 2. The processing structure can be used to make holes on the carrier 6. The stretching part is used to stretch the holes to form the riveting post 61. Then the overall mold is further run. The feeding structure 10 transports the product 5 toward the carrier 6 and aligns the riveting hole on the product 5 with the riveting post 61 on the carrier 6, located below the riveting structure of the overall mold.

[0028] As the upper die base 1 approaches the lower die base 2 again, the riveting punch 121 applies pressure to the riveting post 61, causing the product 5 and carrier 6 to move downwards, deforming the riveting post 61 and pressing it against the top of the product 5, thus completing the riveting of the product 5 and carrier 6. During the riveting process, the positioning pin 43 on the lower die base 2 passes through the carrier 6 and the product 5 to achieve the positioning effect, preventing the product 5 and carrier 6 from shifting. At the same time, the cutting component 9 also cuts the strip of the product 5, completing the separation of the product 5. When the upper die base 1 moves away from the lower die base 2, the knock-off pin 32 extends out of the receiving groove 31 through the elasticity of the knock-off spring 33 and abuts against the product 5, thus facilitating the separation of the product 5 and carrier 6 from the riveting punch 121. At the same time, the elasticity of the strong spring 421 drives the force transmission pin 42 to lift the pressure block 4, causing the positioning pin 43 to move towards the pressure block 4. The riveted product 5 and carrier 6 move away from the positioning pin 43, making it easier to remove the material. The entire operation, including cutting the product 5 strip, transporting the product 5, processing the carrier 6, and riveting the carrier 6 to the product 5, is completed using a single mold. This eliminates the need for manual placement, improving work efficiency and preventing personal safety issues.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
