[0003] For example, the publication number CN215392011 U is a stamping die for automobile parts that is easy to replace the stamping die. The device is easy to replace the stamping die for automobile parts, easy to disassemble and assemble the upper die, has a simple structure, is easy to operate, and ensures the stability of the position of the lower die. No screws are used, which makes it easy to replace the lower die and avoids the position of the upper die and the lower die from shifting during use, and has higher working precision.

[0028] The locking assembly 4 includes a rotating plate 41, a rotating shaft 42, a sliding groove 43, and a pushing plate 44. The rotating shaft 42 is arranged on the supporting plate 3. The rotating shaft 42 is used to limit the rotation of the rotating plate 41 to prevent the rotating plate 41 from moving downward during rotation. The rotating plate 41 is symmetrically arranged on the rotating shaft 42. The rotating plate 41 is used to rotate and lock the placement plate 5 placed on the supporting plate 3 again. The sliding groove 43 is symmetrically opened on the rotating plate 41. The pushing plate 44 is movably arranged on the sliding groove 43. The pushing plate 44 is used to open or contract the angle of the rotating plate 41 through the sliding groove 43 during movement. A sliding rod 45 is arranged on the pushing plate 44. The sliding rod 45 is used to slide, and a fixed block 46 is arranged on the sliding rod 45. The fixed block 46 is used to push the pushing plate 44 fixedly connected to one side of the sliding rod 45 when the pushing assembly 8 is lowered.

[0029] A limit rod 411 is provided on the rotating plate 41, and the limit rod 411 is used to perform secondary limitation on the placement plate 5. The fixed block 46 is symmetrically provided with oblique grooves 461, and the oblique grooves 461 are used to cooperate with the limit rod 83 to be connected to the fixed block 46 without affecting the rise and fall of the pushing component 8. In addition, a pushing component 8 is provided on the fixed block 46, and the pushing component 8 is used to push the fixed block 46 to move.

[0030] An upper support plate 31 is provided on the movable plate 7. The upper support plate 31 is used to support and place the upper mold 61. A locking assembly 9 is provided on the upper support plate 31. The locking assembly 9 is used to seal and clamp the positioning groove 32 when the upper mold 61 carried by the placement plate 5 is replaced and installed. A positioning groove 32 is provided on the upper support plate 31. A placement plate 5 is provided on the positioning groove 32. The upper mold 61 is provided on the side of the placement plate 5 away from the positioning groove 32. A positioning block 51 is provided in the positioning groove 32. The positioning block 51 is used to move and seal the entrance of the positioning groove 32 to prevent the upper mold 61 from having enough space to shake. The positioning block 51 is fixedly connected to the placement plate 5.

[0031] During use, when it is necessary to replace the entire upper and lower molds, the upper mold 61 and the lower mold 6 are first installed on the placement plate 5 respectively. The placement plate 5 with the lower mold 6 installed is placed on the placement plate 5 and is restricted in movement by the limit rod 411. Then, the placement plate 5 with the upper mold 61 installed is locked by the locking block 51 on the placement plate 5 and the locking groove 32 on the upper support plate 31. After the locking is completed, the locking component 9 is moved to block the entrance of the locking groove 32 to prevent the upper mold 61 from shaking in the stamping process. When the device is performing stamping operations, the locking components 4 respectively installed on the upper support plate 31 and the support plate 3 move the push plate 44 after the contact between the push components 8. During the movement of the push plate 44, the rotating plate 41 is driven to rotate. When the rotating plate 41 rotates, the limit rod 411 will perform secondary locking on the respectively connected placement plates 5.

[0032] Example 2

[0033] See also Figures 1 to 6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0034] The pushing assembly 8 includes a striker rod 81, a matching rod 82, a limiting rod 83, a moving rod 84 and a spring 85. The spring 85 is arranged on the support plate 3. The spring 85 is used to restore the striker rod 81 to its original position when there is no external force, and the moving rod 84 is arranged inside the spring 85. The moving rod 84 is used to move up and down on the support plate 3. The striker rod 81 is arranged on the side of the moving rod 84 away from the support plate 3. The striker rod 81 is used to drive the upper striker rod 81 to contact and squeeze each other during the downward stamping process of the upper mold 61 to push the respective pushing assemblies 8 to move. The matching rod 82 is symmetrically arranged on the striker rod 81, and the matching rod 82 is slidably connected to the support plate 3. The limiting rod 83 is symmetrically arranged on the matching rod 82, and the limiting rod 83 is slidably connected to the oblique groove 461. The limiting rod 83 is used to limit between the fixed block 46, and can drive the pushing assembly 8 to return to its original state after the striker rod 81 returns to its original state.

[0035] The locking assembly 9 includes a locking block 91, a telescopic rod 92 and a matching ring 93. The matching ring 93 is arranged on the slide groove 71. The matching ring 93 is used to slide inside the slide groove 71, and drives the telescopic rod 92 to move during the sliding process. Under the movement of the telescopic rod 92, the locking block 91 is engaged in the locking groove 32. The telescopic rod 92 is arranged on the matching ring 93, and the locking block 91 is arranged on the side of the telescopic rod 92 close to the locking groove 32. A guide rail 72 is arranged on the movable plate 7, and the guide rail 72 is slidably connected to the locking block 91. The guide rail 72 is used to enable a certain upward movement when the locking block 91 is in a contact engaged state, so as to facilitate subsequent mold replacement after the locking block 91 moves upward.

[0036] A hydraulic rod 11 is provided on the movable plate 7, and the hydraulic rod 11 is used to push the movable plate 7 to move. The movement of the movable plate 7 drives the upper mold 61 to perform stamping operations. Movable grooves 10 are symmetrically opened on the operating table 1, and the movable grooves 10 are slidingly connected to the limit rod 411. The movable grooves 10 are used to facilitate the movement of the limit rod 411 to perform a secondary locking state on the placement plate 5.

[0037] During use, when the upper mold 61 needs to be locked after replacement, the mobile locking block 91 slides along the guide rail 72, and the entrance of the locking groove 32 is engaged under the sliding of the locking block 91, and the upper support plate 31 is firmly locked to prevent the upper mold 61 driven by the upper support plate 31 from shaking in a certain space during stamping, thereby affecting the normal progress of the entire stamping operation. The impact rod 81 on the pushing assembly 8 can contact and squeeze each other when the upper mold 61 is stamping, thereby pushing the fixed block 46 connected below to move, and the movement of the fixed block 46 drives the pushing plate 44 to push the rotating plate 41 to rotate, thereby performing secondary limitation on the placement plate 5.

[0038] The remaining structures are the same as those of Example 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
