Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] See also Figure 1-4 The utility model provides a technical solution: a stamping device that is easy to disassemble, comprising:

[0031] The upper die base 1 has a first hanging ring 11 disposed on one of its opposite sides;

[0032] The lower die base 2 has a second hanging ring 21 on one of its opposite sides, a mounting hole 22 is provided in the lower die base 2, at least one locking rod 3 is provided in the mounting hole 22, one end of the locking rod 3 is rotatably installed in the mounting hole 22, and a first receiving groove 12 corresponding to the locking rod 3 is provided on the upper die base 1;

[0033] A first locking block 4 is provided with a first threaded rod, the first threaded rod is threadedly connected to the lower die base 2, the end of the first threaded rod extends into the mounting hole 22, and the free end of the locking rod 3 is provided with a first notch 31 whose shape matches the first threaded rod;

[0034] The second locking block 5 is provided with a second threaded rod, which is threadedly connected to the upper die base 1, and the end of the second threaded rod extends into the first receiving groove 12. The locking rod 3 is provided with a first through hole 32 corresponding to the position of the second threaded rod.

[0035] Two locking rods 3 are provided on the lower die base 2, and the two locking rods 3 are symmetrically arranged on both sides of the first threaded rod. On the one hand, the locking effect of the upper die base 1 and the lower die base 2 is improved, and on the other hand, one first locking block 4 can realize the position locking of the two locking rods 3, simplifying the device structure.

[0036] An arc-shaped positioning block 221 is provided on the side wall of the mounting hole 22, and an arc-shaped notch 33 whose shape matches the arc-shaped positioning block 221 is provided on the side wall of the locking rod 3. When the locking rod 3 is rotated downward to be in a vertical state, the arc-shaped positioning block 221 is inserted into the arc-shaped notch 33, so that when the locking rod 3 is used as a reference during the hoisting process of the lower die base 2, it can be prevented that when the lower die base 2 descends to a height lower than the length of the locking rod 3 extending out of the lower die base 2, the upward movement of the locking rod 3 causes its own rotation axis to deform, thereby improving its reliability.

[0037] The first locking block 4 is provided with a plurality of first arcuate grooves 41 equidistantly arranged circumferentially. Specifically, the first locking block 4 is provided with four first arcuate grooves 41 equidistantly arranged circumferentially, which facilitates holding the first locking block 4 and further facilitates rotation and adjustment of the first threaded rod.

[0038] The rotating shaft of the locking rod 3 extends out of the lower die base 2 and is connected to the control block 6 . The control block 6 is provided with a plurality of second-shaped grooves arranged equidistantly in the circumferential direction, so as to facilitate the control of the rotation of the locking rod 3 .

[0039] Working principle: the upper die base 1 is used to fix the upper die, and the lower die base 2 is used to fix the lower die. The upper die base 1 can be hoisted by the first hoist ring 11. When the mold is disassembled from the press, after the upper die base 1 is separated from the driving mechanism of the press, the base moves the upper die and the lower die in the mold-closing state out of the press together.

[0040] In order to increase the hoisting speed, it is not necessary to hoist the upper die base 1 and the lower die base 2 separately. Instead, the first locking block 4 is rotated and retreated, and the end of the first threaded rod is disengaged from the first notch 31 of the free end of the locking rod 3, and the locking rod 3 is unlocked, so that the free end of the locking rod 3 rotates and extends into the first receiving groove 12, and the second locking block 5 is rotated so that the second threaded rod of the second locking block 5 extends into the first through hole 32, so as to achieve the locking of the upper die base 1 and the lower die base 2. After the lower die base 2 is hoisted by the second lifting ring 21, the upper die and the lower die in the mold closing state can be disassembled together to prevent displacement during the hoisting process, facilitate disassembly, effectively improve the disassembly efficiency of the mold, and avoid mold wear during the disassembly process. At the same time, when the lower die base 2 is hoisted on the base, the locking rod 3 can be used as a reference to indicate whether the lower die base 2 is aligned with the installation position on the base.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
