[0027] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0028] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an in-mold lateral riveting unloading structure includes: a positioning insert 100, an unloading ejection assembly 200, and a riveting assembly 300. The positioning insert 100 has a riveting clearance position on its side. When the product 20 is placed on the positioning insert 100, the bent claw riveting position 21 on the product 20 is located at the riveting clearance position. The unloading ejection assembly 200 includes a push rod 210 and a spring 220. The push rod 210 is movably installed inside the positioning insert 100, and the spring 220 is sleeved on the push rod 210. One end of the push rod 210 is located at the riveting clearance position and faces the bent claw riveting position 21. The riveting assembly 300 is located on one side of the riveting clearance position and is used to perform riveting operations on the bent claw riveting position 21.

[0029] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 2As shown, this is an in-mold lateral riveting structure before improvement. When using this structure to perform lateral riveting operations on product 20, the riveting punch 320 presses into product 20, forcing the material of the bent claw riveting position 21 of product 20 into the side countersunk hole of the positioning insert 100, thereby riveting the two bent claws together. After riveting is completed, when the riveting punch 320 retracts and unloads the product, the material of the bent claw riveting position 21 pressed into the side countersunk hole may occasionally get stuck on the side wall of the countersunk hole, causing difficulty in unloading and even leading to quality problems such as deformation of product 20, reducing the yield of product 20. Based on this, in this utility model, by adding a side unloading ejection component 200, the problem of difficult unloading of product 20 can be solved. Specifically, after the bending operation of product 20 is completed, product 20 is placed on positioning insert 100. Positioning insert 100 supports and positions product 20. Simultaneously, the two curved claws on product 20 are located on the side of positioning insert 100, and the crimping positions 21 of the curved claws are located at the crimping clearance position. A space for installing the unloading ejector assembly 200 is provided on positioning insert 100. One end of ejector rod 210 is located at the crimping clearance position. The ejector rod 210, in conjunction with the side wall of the crimping clearance position, forms the countersunk hole structure required for riveting. Then, the crimping assembly 300 rivets the curved claw crimping positions 21 on product 20. After the operation, the material of the bent claw riveting position 21 is squeezed by the riveting assembly 300 to abut against the end face of the push rod 210. At the same time, the push rod 210 is pressed and moves away from the riveting assembly 300. After the riveting operation is completed, the riveting assembly 300 returns to the initial position, and the spring 220, which was originally in a compressed state, is released, pushing the push rod 210 to move closer to the riveting assembly 300. This pushes the bent claw riveting position 21 of the product 20 out of the riveting clearance position, realizing the unloading of the product 20. This solves the problem of poor unloading caused by lateral riveting in the mold, improves the yield rate, and can also improve production efficiency and reduce costs.

[0030] In one embodiment, the unloading ejection assembly 200 further includes a pad 230, which is fixed inside the positioning insert 100. One end of a spring 220 is mounted on the pad 230 and the spring 220 is sleeved on the push rod 210. The end of the push rod 210 away from the riveting clearance position moves toward or away from the pad 230.

[0031] It should be noted that a limiting protrusion 211 is provided on the push rod 210, and the spring 220, which is sleeved on the push rod 210, is located between the limiting protrusion 211 and the pad 230. The pad 230 provides stable support for the spring 220. At the same time, the spring 220 is compressed or released when the push rod 210 moves. For the riveted state, please refer to [reference needed]. Figure 3 and Figure 4As shown, the push rod 210 is compressed by the riveting assembly 300 to retract the compression spring 220. Simultaneously, the end of the push rod 210 away from the bent claw riveting position 21 presses against the pad 230, stopping the push rod 210. At this point, the riveting is complete. Thus, the push rod 210, in conjunction with the pad 230, restricts the movement distance of the push rod 210, thereby limiting the height of the riveting protrusion of the bent claw riveting position 21. Furthermore, the push rod 210 does not directly abut against the positioning insert 100, but rather against the pad 230. Therefore, even if the pad 230 wears out after prolonged use, repairs can be completed by simply replacing the pad 230, reducing maintenance difficulty and extending the service life of the positioning insert 100.

[0032] Furthermore, the riveting assembly 300 includes a slider 310, a riveting punch 320, and a drive member 330. The slider 310 is disposed on one side of the positioning insert 100. The riveting punch 320 is mounted on the slider 310, and the riveting end of the riveting punch 320 faces the bent claw riveting position 21. The drive member 330 is connected to the slider 310 and is used to drive the slider 310 to move towards the bent claw riveting position 21 so that the riveting punch 320 performs a riveting operation on the bent claw riveting position 21.

[0033] It should be noted that the drive component 330 drives the slider 310 to move closer to the bent claw riveting position 21, so that the riveting punch 320 punches into the bent claw riveting position 21. The material on the bent claw riveting position 21 is squeezed into the riveting relief position to form a riveting protrusion, and the push rod 210 retracts to compress the spring 220. The push rod 210 retracts until it stops moving when it is against the pad block 230, thus completing the riveting operation. Then the drive component 330 drives the slider 310 back to the initial position, the spring 220 releases the compression force, and drives the push rod 210 to push out the riveting protrusion, thereby achieving the unloading function.

[0034] Furthermore, the driving component 330 includes a pressing block 331 and a reset elastic element 332. The pressing block 331 is abutting and connected to the slider 310. The pressing block 331 is used to push the slider 310 to move towards the direction of the bent claw riveting position 21. The reset elastic element 332 is located between the slider 310 and the positioning insert 100. The reset elastic element 332 is used to push the slider 310 to move away from the bent claw riveting position 21.

[0035] It should be noted that the lower pressure block 331 can be installed on the upper mold base of the mold, and the up and down movement of the upper mold base drives the up and down movement of the lower pressure block 331. The movement of the slider 310 is realized by the lower pressure block 331 in conjunction with the reset elastic element 332. Specifically, in this embodiment, the slider 310 is provided with a slider inclined surface 311, and the lower pressure block 331 is provided with a pressure block inclined surface 331a. When the lower pressure block 331 performs the downward pressing movement, the pressure block inclined surface 331a moves obliquely from top to bottom along the slider inclined surface 311, so that the slider 310 moves towards the direction of the bent claw riveting position 21. That is, when the lower pressure block 331 moves downward, the downward vertical movement of the lower pressure block 331 is converted into a horizontal lateral movement of the slider 310 through the engagement of the pressure block inclined surface 331a and the slider inclined surface 311 of the slider 310, so that the slider 310 moves towards the bent claw riveting position 21. When the lower pressure block 331 moves upward, the pressure block inclined surface 331a rises, releasing the pressure on the slider 310. The pressure of the reset elastic element 332 on the slider 310 causes the slider 310 to move away from the bent claw riveting position 21, thereby resetting the slider 310. In this embodiment, the reset elastic element 332 is a reset spring 220. The spring 220 is low in cost, easy to replace, and can provide a continuous and stable reset force to ensure that the slider 310 returns to its original position, avoiding jamming of the riveting punch 320 due to insufficient reset. In another embodiment, the driving component can also be a driving cylinder, which drives the movement of the slider.

[0036] In one embodiment, the in-mold lateral riveting and unloading structure further includes a template 400, a positioning insert 100 mounted on the template 400, and a slider 310 movably mounted on the template 400. The template 400 serves as the basic mounting carrier, the positioning insert 100 is fixed on it to ensure the position reference, and the slider 310 is movably mounted on the template 400. The template 400 restricts the movement trajectory of the slider 310. In this embodiment, a sliding positioning groove is provided on the template 400, and a sliding positioning protrusion is provided on the side of the slider 310 facing the template 400. The sliding positioning protrusion is connected to the sliding positioning groove. When the slider 310 moves, the sliding positioning protrusion moves along the sliding positioning groove, thereby preventing the slider 310 from shifting or wobbling during movement, ensuring that the riveting punch 320 is always aligned with the bent claw riveting position 21, and improving riveting accuracy.

[0037] A mold includes the aforementioned in-mold lateral riveting and unloading structure. The mold can be a lateral riveting mold or a bending and riveting integrated mold. The mold typically includes an upper mold base and a lower mold base. Except for the lower pressure block 331, which needs to be installed on the upper mold base and move up and down with the upper mold base, the rest of the structure can be installed on the template 400 of the lower mold base.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
