Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die convenient for rapid demoulding. Background Technique

[0002] A stamping die is a kind of process equipment that processes materials into workpieces or semi-finished products in stamping processing and is the main process equipment in industrial production. Using a stamping die to produce parts can use rolled steel plates or steel strips mass-produced by metallurgical factories as blanks, and no heating is required during production, which has the advantages of high production efficiency, good quality, light weight, and low cost.

[0003] Publication No. CN217858512U discloses a stamping die convenient for rapid demoulding. When the sealing plate moves downward, it is inserted into the slot, and then the sealing plate blocks the air holes. The L-shaped rod drives the push plate to move downward, and the push plate pushes the airbag, so that the air in the airbag is input into the air holes through the connecting joint. When the extrusion die moves upward, the air holes are in contact and sealed, and then the air is input into the die cavity through the air holes, and then the parts in the die cavity are pushed up, and then the parts can be quickly removed from the die cavity. However, the following problems still exist in the actual use of this patent:

[0004] The die is ejected by air, making it impossible to ensure that the workpiece can be demoulded for sure. If the quality of the workpiece is relatively heavy, then simply inputting gas may not be able to demould the workpiece, resulting in the need for manual intervention when the workpiece cannot be demoulded, which will affect the work efficiency.

[0005] A stamping die convenient for rapid demoulding is proposed to solve the problems mentioned above. Content of the Utility Model

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a stamping die facilitating quick demolding, including a bottom plate 1, and a die groove 2 fixed to the top of the bottom plate 1, and support legs 3 symmetrically fixed to the bottom of the bottom plate 1; a demolding assembly 4 is provided at the bottom of the bottom plate 1, the demolding assembly 4 includes a connecting plate 401, and a rotating block 402 is rotatably connected to the bottom of the connecting plate 401, and a first threaded rod 403 is rotatably connected to the top of the connecting plate 401, and the rotating block 402 is fixedly connected to the first threaded rod 403; wherein, a moving block 404 is threadedly connected to the outside of the first threaded rod 403, and a limiting rod 4041 is fixedly connected to the top of the connecting plate 401, and a fixing sleeve 4042 is fixedly connected to the front of the moving block 404, and the fixing sleeve 4042 slides on the outside of the limiting rod 4041; wherein, racks 405 are symmetrically fixed to both sides of the moving block 404, and an empty groove 406 is formed in the inside of the bottom plate 1, and gears 407 are symmetrically rotatably connected in the inside of the bottom plate 1, as Figure 5 shown, rotating the rotating block 402 causes the rotating block 402 to drive the first threaded rod 403 to rotate, then the first threaded rod 403 will drive the position of the moving block 404 to rise, then the moving block 404 will drive the positions of the racks 405 on both sides to rise, then the racks 405 will drive the gears 407 on both sides to rotate, and the gears 407 are located inside the empty groove 406, and the racks 405 are meshed with the gears 407.

[0029] A fixing rod 408 is fixedly connected to the front of the gear 407, and a telescopic rod 409 is rotatably connected to the top of the fixing rod 408, and sliding plates 410 are symmetrically slidably connected in the die groove 2, and the top of the telescopic rod 409 is slidably connected to the sliding plate 410; an installation block 411 is fixedly connected to the inside of the bottom plate 1, and the installation block 411 is located inside the empty groove 406, and a spring 412 is fixedly connected to the top of the installation block 411, and a square block 413 is fixedly connected to the top of the spring 412; a pushing block 414 is fixedly connected to the top of the square block 413, and the pushing block 414 is L-shaped; an extrusion block 415 is fixedly connected to one side of the square block 413, as Figure 3As shown, the gear 407 drives the rotation of the fixed rod 408 on the front side. Then, the fixed rod 408 drives the rotation and position movement of the telescopic rod 409. Then, the telescopic rod 409 drives the position movement of the sliding plates 410 on both sides. Then, the sliding plates 410 slide inside the mold groove 2, so that the mold disengages from the top of the sliding plates 410, thus demolding the bottom of the workpiece. Secondly, when the moving block 404 moves to a certain extent, it squeezes the extrusion block 415. Then, the extrusion block 415 drives the square block 413 to rise. Then, the square block 413 stretches the spring 412. At the same time, the square block 413 drives the position of the push block 414 to rise. Then, the push block 414 pushes the workpiece, causing the workpiece to rise, so that the two sides of the workpiece disengage from the mold groove 2, thus demolding the workpiece.

And the bottom of the second threaded rod 504 is rotatably connected to the connecting block 505. And symmetrically fixed to the bottom of the sliding plate 503 are pressing blocks 506. As Figure 5 shown, rotate the second threaded rod 504, so that the second threaded rod 504 drives the position of the connecting block 505 to descend. Then, the connecting block 505 drives the position of the sliding plate 503 to descend. Then, the sliding plate 503 drives the position of the pressing block 506 to descend, so that the pressing block 506 shapes the workpiece.

[0031] Working principle: Before using this stamping die that is convenient for rapid demolding, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown, first, when it is necessary to demold the workpiece inside the mold groove 2, the rotating block 402 can be rotated, so that the rotating block 402 drives the first threaded rod 403 to rotate. Then, the first threaded rod 403 will drive the position of the moving block 404 to rise. Then, the moving block 404 will drive the positions of the racks 405 on both sides to rise. Then, the racks 405 will drive the gears 407 on both sides to rotate. Then, the gears 407 will drive the fixed rod 408 in the front to rotate. Then, the fixed rod 408 will drive the telescopic rod 409 to rotate and move. Then, the telescopic rod 409 will drive the positions of the sliding plates 410 on both sides to move. Then, the sliding plates 410 will slide inside the mold groove 2, so that the mold is separated from the top of the sliding plates 410, so as to demold the bottom of the workpiece. Secondly, when the moving block 404 moves to a certain extent, it will squeeze the squeezing block 415. Then, the squeezing block 415 will drive the square block 413 to rise. Then, the square block 413 will stretch the spring 412. At the same time, the square block 413 will drive the position of the pushing block 414 to rise. Then, the pushing block 414 will push the workpiece, so that the workpiece rises, so as to separate the two sides of the workpiece from the mold groove 2, so as to demold the workpiece.

[0032] The second threaded rod 504 can be rotated, so that the second threaded rod 504 drives the position of the connecting block 505 to descend. Then, the connecting block 505 will drive the position of the sliding plate 503 to descend. Then, the sliding plate 503 will drive the position of the pressing block 506 to descend, so that the pressing block 506 shapes the workpiece.
