By incorporating an anti-wear and easy-release mechanism, elastic colloid, and grooves, wear between the workpiece and the lower mold can be effectively avoided, thereby increasing the service life of the lower mold, reducing the scrap rate of the lower mold, and thus improving the riveting effect and quality of the workpiece, reducing defective products. The elastic colloid facilitates workpiece demolding, and after riveting, issues such as difficulty in demolding or adhesion are less likely to occur. Therefore, the effectiveness of the riveting device is further improved, greatly enhancing its practicality.

[0004] The above-mentioned scheme poses a risk to the safety of operators during the riveting process due to the approach and separation of the upper and lower dies, as well as the risk of splashing or accidental contact during the riveting process. In addition, the existing mold structure often requires manual removal of the protective device after riveting, which not only reduces work efficiency but may also cause safety hazards due to improper operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a protective mold structure for riveting avoidance, including: a processing table 1, a lower mold 2 installed on the upper end of the processing table 1, a sliding groove 3 opened on the upper end of the processing table 1 and on both sides of the lower mold 2, a guide rod 4 fixedly connected to the inner wall of each of the two sliding grooves 3, a protective groove 5 opened on the upper end of the processing table 1 and the outer wall of the lower mold 2, a protective component 6 provided on the inner wall of the protective groove 5, and a connecting cavity 7 opened between the protective groove 5 and the sliding groove 3;

[0024] The protective assembly 6 includes a protective frame 601, a rotating rod 602, and a sliding sleeve 603. The protective frame 601 is slidably connected to the inner wall of the protective groove 5, and a protective pad 604 is installed on the inner wall of the protective frame 601. Two toothed plates 605 are fixedly connected to the outer wall of the protective frame 601. The rotating rod 602 is rotatably connected to the inner wall of the connecting cavity 7, and a gear 606 is fixedly connected to the outer wall of the rotating rod 602. The sliding sleeve 603 is fitted onto the outer wall of the guide rod 4, and a toothed groove 607 is provided on one side of the sliding sleeve 603. The protective assembly 6 ensures protection during the riveting process, preventing accidental injury to the operator.

[0025] A bracket 8 is fixedly connected to the upper end of the two guide rods 4. A hydraulic cylinder 9 is mounted on the upper end of the bracket 8. A connecting plate 10 is fixedly connected to the lower end of the hydraulic cylinder 9. An upper mold 11 is fixedly connected to the lower end of the connecting plate 10. The connecting plate 10 and the upper mold 11 are driven to move vertically by the hydraulic cylinder 9, providing a stable riveting force.

[0026] A riveting punch 111 is installed at the lower end of the upper die 11, and a groove 201 corresponding to the riveting punch 111 is opened at the upper end of the lower die 2. The cooperation between the riveting punch 111 and the groove 201 of the lower die ensures the firm riveting of the metal parts during the riveting process.

[0027] The inner wall of the protective groove 5 is provided with an auxiliary groove 501 adapted to the toothed plate 605, and the outer wall of the toothed plate 605 is slidably connected to the inner wall of the auxiliary groove 501. The auxiliary groove 501 provides sliding guidance for the toothed plate 605, and also restricts the movement of the protective frame 601, further improving the stability of the protective frame 601 when it moves.

[0028] The inner wall of the sliding sleeve 603 is slidably connected to the guide rod 4, and the outer wall of the sliding sleeve 603 is slidably connected to the slide groove 3. Through the sliding connection between the sliding sleeve 603, the guide rod, and the slide groove 3, a dual guiding mechanism is formed to ensure that the sliding sleeve 603 moves smoothly up and down along the guide rod 4.

[0029] Gear 606 is located between toothed plate 605 and sliding sleeve 603, and gear 606 meshes with toothed plate 605 and tooth groove 607. The movement of protective frame 601 is linked to the lifting and lowering of sliding sleeve 603 through meshing transmission.

[0030] Both guide rods 4 pass through and are slidably connected to the connecting plate 10, and the lower end of the connecting plate 10 is fixedly connected to the sliding sleeve 603. The guide rods 4 provide guidance for the connecting plate 10, making the connecting plate 10 more stable during the lifting and lowering process. The lifting and lowering of the connecting plate 10 drives the sliding sleeve 603 to perform lifting and lowering operations.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During riveting, the hydraulic cylinder 9 is activated, driving the connecting plate 10 to move downwards, causing the upper die 11 and the riveting punch 111 to approach the lower die 2. As the connecting plate 10 moves downwards, it causes the lower end of the sliding sleeve 603 to slide down synchronously along the guide rod 4. During the downward movement of the sliding sleeve 603, the toothed groove 607 on its side wall meshes with the gear 606, thereby driving the gear 606 to rotate. At the same time, the gear 606 meshes with the toothed plate 605, thereby causing the toothed plate 605 and the protective frame 601 to slide upwards along the protective groove 5, thus raising the protective frame 601. At this time, the protective pad 604 is located on the outer side wall of the lower die 2, forming a protective enclosure around the outer side wall of the lower die 2 to prevent injury to the operator during the riveting process. In addition, the descent of the upper die 11 causes the riveting punch 111 to... Approaching the corresponding groove 201 at the upper end of the lower die 2, when the riveting punch 111 engages with the groove 201, it can firmly rivet the metal parts placed on the lower die 2. Throughout the riveting process, the protective frame 601 always surrounds the outer wall of the lower die 2, providing safety for the operator. After the riveting is completed, the hydraulic cylinder 9 drives the connecting plate 10 and the upper die 11 to move upward. When the connecting plate 10 rises, it will drive the sliding sleeve 603 to slide upward along the guide rod 4. During the rise of the sliding sleeve 603, through the meshing transmission of the gear 606 and the toothed plate 605, the protective frame 601 will move downward along the inner wall of the protective groove 5 and retract into the inner wall of the protective groove 5, making it easier for the operator to remove the processed workpiece.
