DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0026] With reference to Figure 1 - Figure 3 The utility model provides an embodiment: a stamping die with replaceable stamping die head, including base 1, base 1 top fixedly connected with support column 4, support column 4 top fixedly connected with support plate 6, support plate 6 top fixedly connected with hydraulic cylinder 7, hydraulic cylinder 7 output fixedly connected with sliding plate 5, sliding plate 5 slidingly connected in support column 4 outer wall, sliding plate 5 one side fixedly connected with connecting frame 8, connecting frame 8 inside slidingly connected with stamping head 9, connecting frame 8 inside is provided with buckle assembly, and buckle assembly is used for clamping stamping die head;

[0027] Buckle assembly includes sliding column 11 and bevel block 14, sliding column 11 slidingly connected in connecting frame 8 inside, bevel block 14 top fixedly connected in sliding column 11 bottom, connecting frame 8 top fixedly connected with fixed frame 10, sliding column 11 outer wall is equipped with spring one 13, and spring one 13 one end fixedly connected in fixed frame 10 inside, and spring one 13 other end fixedly connected with disc 26, sliding column 11 top fixedly connected with connecting rod 12, base 1 inside fixedly connected with fixed frame 18, and fixed frame 18 inside is provided with stripping assembly, and stripping assembly is used for fast stripping.

[0028] Specifically, when the punch die head needs to be replaced, the user first needs to start the replacement process by pulling the connecting rod 12. When the connecting rod 12 moves upward, it drives the sliding column 11 to slide smoothly inside the fixed frame 10. The upward movement of the sliding column 11 pushes the bevel block 14 and the disc 26 to move upward synchronously. When the disc 26 rises, it gradually exerts pressure on the spring 13, causing the spring 13 to be compressed. In this process, the engagement between the bevel block 14 and the punch head 9 is released. With the upward movement of the bevel block 14, the punch head 9 can easily move out of the original installation position. In this way, the user can quickly and conveniently pull out the punch head 9 from the connecting frame 8, thereby achieving the operation of disassembling the punch die head. When a punch die head of a different model or specification needs to be replaced, the operation process is also simple. When installing a new die head, the operator aligns one side of the punch head 9 and applies appropriate pressure to press the bevel block 14 outward. At this time, the punch head 9 is gradually installed in place. After installation is complete, the spring 13 releases the stored elastic force, driving the bevel block 14 to automatically rebound and insert into the fixed clamping groove of the punch head 9, achieving stable clamping and fixing of the punch die head. This design not only ensures quick and convenient replacement of the die head, but also effectively avoids instability during installation, ensuring the service life of the die.

[0029] With reference to Figure 4 and Figure 5 , the demolding assembly includes a top column 24 and a top plate 16. The top column 24 is slidingly connected inside the fixed frame 18, and the top plate 16 is fixedly connected to the top of the top column 24. The base 1 has a support frame 2 fixedly connected to the top, and the support frame 2 has a die frame 3 fixedly connected to the top. The fixed frame 18 has a fixed block 15 fixedly connected to the side wall, and the fixed block 15 has a hydraulic rod 17 fixedly connected to the top. The hydraulic rod 17 has a triangular block 21 fixedly connected to the output end, and the triangular block 21 has a sliding rail 20 fixedly connected to the bottom. The fixed frame 18 has a limiting frame 19 fixedly connected inside, and the sliding rail 20 is slidingly connected to the top of the limiting frame 19. The top column 24 has a spring 25 sleeved on the outer wall, and the spring 25 has one end fixedly connected inside the fixed frame 18 and the other end fixedly connected to a notched frame 23. The notched frame 23 has a circular wheel 22 arranged inside, and the circular wheel 22 is rotatably connected inside the notched frame 23. The circular wheel 22 is slidingly connected to the top of the triangular block 21, and the circular wheel 22 is in contact with the triangular block 21.

[0030] Specifically, after the stamping die is completed, in order to smoothly take out the molded die from the die, demolding treatment is needed, first, the operator starts the output end of the hydraulic rod 17, pushes the triangular block 21 and the sliding rail 20 to slide smoothly on the limiting frame 19, with the movement of the triangular block 21, the side of the circular wheel 22 is subjected to sliding extrusion force, so that the notch frame 23 is displaced, driving the jacks 24 and the top plate 16 to move upward synchronously, in this process, the rising of the notch frame 23 will directly extrude the spring 25, so that it is deformed under pressure, when the molded die is taken out, when the output end of the hydraulic rod 17 stops output, the spring 25 will quickly release the stored elastic force, push the notch frame 23 to return to the original position, at the same time, the descending of the notch frame 23 will drive the jacks 24 and the top plate 16 to reset, completing the demolding action, at this time, the molded part in the die will be separated from the die, completing the demolding process.

[0031] Working principle: when the stamping die is used, the stamping die head needs to be replaced, first pull the connecting rod 12, the connecting rod 12 moves upward, which will drive the sliding column 11 to slide inside the fixed frame 10, when the sliding column 11 slides upward, it will drive the bevel block 14 and the disc 26 to move upward synchronously, when the disc 26 moves upward, it will extrude the spring 13, at this time the bevel block 14 and the stamping head 9 are separated, then slide the stamping head 9, pull it out from the connecting frame 8, so as to achieve the purpose of disassembling the stamping head 9 installed on the stamping die equipment, when different stamping die heads need to be replaced, the bevel block 14 is extruded on one side of the stamping head 9, when the stamping head 9 is installed in place, the spring 13 releases the elastic force to rebound and inserts the bevel block 14 into the stamping head 9, so as to achieve the purpose of clamping and fixing the stamping die head, when the stamping die is stamped and molded, the molded die needs to be demolded, first start the output end of the hydraulic rod 17 to push the triangular block 21 and the sliding rail 20 to slide on the limiting frame 19, the side of the triangular block 21 slides and extrudes the circular wheel 22, so that the notch frame 23 drives the jacks 24 and the top plate 16 to move upward, when the notch frame 23 moves upward, it will extrude the spring 25, when the demolding is completed and the molded die is taken out, the output end stops output, the spring 25 releases the elastic force to drive the notch frame 23 to move downward, at the same time, the jacks 24 and the top plate 16 are reset, through the above process, the purpose of quickly and completely demolding the molded die is achieved.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
