[0023] The quick-release die fixing mechanism 5 includes the plug-in seat 501, the plug-in block 502, the connecting rod 503, the threaded inner cavity 504, the sliding seat 505, the stabilizing block 506, the rotating rod 507, the limiting plate 508, the limiting sleeve 509, the tension spring 510, the cross plug rod 511, the pull rod 512 and the threaded plug rod 513, the top of the stamping die body 6 is fixedly installed with the plug-in seat 501, the sliding seat 505 and the limiting plate 508, the inside of the plug-in seat 501 is plugged with the plug-in block 502, the top of the plug-in block 502 is fixedly installed with the connecting rod 503, the inside of the plug-in block 502 is provided with the threaded inner cavity 504, the top of the sliding seat 505 is slidingly connected with the stabilizing block 506, the inside of the stabilizing block 506 is rotatably connected with the rotating rod 507, the right side of the limiting plate 508 is fixedly installed with the limiting sleeve 509, the inside of the limiting sleeve 509 is fixedly installed with the tension spring 510, the inside of the limiting sleeve 509 is slidingly installed with the cross plug rod 511 and the pull rod 512, the inside of the threaded inner cavity 504 is threadedly connected with the threaded plug rod 513.

[0024] Specifically, in the actual production scene, the stamping table 1 provides a stable support base for the entire mold system, the mold seat 2 fixedly installed on the top thereof is used for placing a workpiece to be stamped, and the support plate 3 plays a key role in connecting and supporting the hydraulic cylinder 4, so as to ensure that the hydraulic cylinder 4 can be stably installed above the stamping table 1.

[0025] The utility model discloses a key is quick -detachable mould fixed establishment 5, it is the core component of realizing stamping die body 6 quick replacement, the top fixed mounting of stamping die body 6 has inserted seat 501, sliding seat 505 and limiting plate 508, wherein, inserted seat 501 inside inserts inserted block 502, and the bottom of connecting rod 503 fixedly connected with hydraulic cylinder 4 on inserted block 502 top, this makes stamping die body 6 can be driven under the hydraulic cylinder 4 and carries out stamping operation.

[0026] Specifically, the threaded inner cavity 504 is formed in the inserted block 502, and the threaded plug rod 513 is screwed with the threaded inner cavity 504; the stable block 506 is slidably connected to the top of the sliding seat 505; the rotating rod 507 is rotatably connected to the inside of the stable block 506; and the right side of the rotating rod 507 is fixedly connected with the left side of the threaded plug rod 513. With the above structure, when the rotating rod 507 rotates, the threaded plug rod 513 can be screwed into or out of the threaded inner cavity 504.

[0027] The limiting sleeve 509 fixedly installed on the right side of the limiting plate 508 has a complex and key internal structure. A sliding block is slidably connected to the inside of the limiting sleeve 509. The right sides of the tension spring 510 and the cross-shaped plug rod 511 are fixedly connected with the sliding block. The left side of the tension spring 510 is fixedly connected with the inner left wall of the limiting sleeve 509. Meanwhile, the pull rod 512 is also fixedly connected with the sliding block. With the above structure, when the pull rod 512 is pulled, the sliding block will slide in the limiting sleeve 509, thereby driving the cross-shaped plug rod 511 to move and stretching the tension spring 510.

[0028] The left and right sides of the inserted seat 501 are respectively provided with through holes matched with the threaded plug rod 513 and the cross-shaped plug rod 511. The two through holes are key interfaces for quickly fixing and disassembling the stamping die body 6.

[0029] Specifically, when the stamping die body 6 needs to be replaced, the operator first holds the pull rod 512 and pulls it away from the stamping die body 6. The pull rod 512 drives the sliding block connected therewith to slide in the limiting sleeve 509. At this time, the tension spring 510 is stretched to generate elastic potential energy. The movement of the sliding block makes the cross-shaped plug rod 511 move to the left. When the cross-shaped plug rod 511 completely separates from the through hole on the inserted seat 501, the cross-shaped plug rod 511 disappears from the transverse limiting action between the inserted seat 501 and the inserted block 502.

[0030] At the same time, since the rotating rod 507 is fixedly connected with the threaded plug rod 513, and the rotating rod 507 is rotationally connected in the stabilizing block 506, and the stabilizing block 506 is slidingly connected with the sliding seat 505, in the process of pulling the pull rod 512, the rotating rod 507 will rotate with the movement of the cross plug rod 511, the rotation of the rotating rod 507 drives the threaded plug rod 513 to gradually rotate out of the threaded inner cavity 504, when the threaded plug rod 513 is completely rotated out of the threaded inner cavity 504, the vertical and horizontal connection between the stamping die body 6 and the quick-release die fixing mechanism 5 is released, at this time, the operator can easily take off the stamping die body 6 from the quick-release die fixing mechanism 5.

[0031] When installing a new stamping die body 6, the operator only needs to insert the plug-in seat 501 at the top of the new stamping die body 6 into the plug-in block 502 on the quick-release die fixing mechanism 5, in the process of insertion, ensure that the positions of the plug-in seat 501 and the plug-in block 502 accurately correspond, then loosen the pull rod 512, at this time, under the action of the elastic potential energy of the tension spring 510, the sliding block will slide towards the direction close to the stamping die body 6, driving the cross plug rod 511 to move rightwards and insert into the through hole of the plug-in seat 501, achieving horizontal limiting, at the same time, the rotating rod 507 reversely rotates, driving the threaded plug rod 513 to rotate into the threaded inner cavity 504, completing vertical fixing, in this way, the new stamping die body 6 is quickly and stably installed on the quick-release die fixing mechanism 5.

[0032] In the daily stamping operation process, the hydraulic cylinder 4 will perform extension and retraction movement according to the preset program, when the hydraulic cylinder 4 extends downwards, the stamping die body 6 is driven to move downwards by the connecting rod 503, exerting pressure on the workpiece placed on the die seat 2, completing the stamping operation.

[0033] In summary, the stamping die with replaceable stamping die head realizes quick replacement of the stamping die body 6 through the quick-release die fixing mechanism 5, when it is necessary to replace the stamping die body 6, the pull rod 512 is pulled, the sliding block is moved by the pull rod 512, the tension spring 510 is stretched, the cross plug rod 511 moves leftwards and separates from the through hole on the plug-in seat 501, at the same time, the rotating rod 507 rotates, driving the threaded plug rod 513 to rotate out of the threaded inner cavity 504, at this time, the stamping die body 6 can be separated from the quick-release die fixing mechanism 5, when installing a new die, reverse operation can be performed, this design greatly shortens the time for replacing the die head, reduces the downtime, improves the production efficiency, solves the problem that for some stamping dies, due to the fixed connection between the die head and the die seat, when it is necessary to replace the die head to adapt to different product specifications or perform die maintenance, a long time and complex disassembly and assembly process are often required, which not only increases the downtime and reduces the production efficiency, but also increases the labor cost and the risk of equipment damage.
