Description
Technical Field
[0001] This utility model relates to the field of die-cutting molds, specifically to a die-cutting mold that can be quickly disassembled and assembled. Background Technology
[0002] A die is a special mold used for die-cutting processing. It is widely used in many industries such as packaging, printing, electronics, leather, and foam. Its core function is to precisely cut, crease, or punch various sheet materials such as paper, plastic, metal foil, and cloth according to a preset shape, so as to achieve standardized mass production of materials.
[0003] In practical use, die-cutting dies usually need to be tightly connected to the mounting base on the machine base of equipment such as die-cutting machines and stamping machines. The core function of the mounting base is to provide a stable support base for the die-cutting die, ensuring that the die-cutting die will not shift or shake during high-speed stamping or die-cutting, thereby ensuring the accuracy of processing dimensions and the consistency of product quality.
[0004] Currently, die-cutting molds and mounting bases are mostly locked together using bolts. While the axial tightening force of the bolts ensures the stability of the connection between the die-cutting mold and the mounting base, it significantly complicates the assembly and disassembly of the die-cutting mold. When a die-cutting mold needs to be replaced due to wear, chipping, or other defects in the cutting edge after long-term use, workers must first use special tools to remove all the locking bolts one by one to remove the old die-cutting mold from the mounting base. When installing a new die-cutting mold, the positioning holes between the die-cutting mold and the mounting base must be realigned, and the bolts must be tightened one by one with tools. Furthermore, the tightness of the bolts must be reinforced to ensure the die-cutting mold is in a stable state. The entire assembly and disassembly process is cumbersome and time-consuming, increasing the workload of workers and significantly reducing the convenience of subsequent maintenance and replacement of the die-cutting mold. Therefore, it is necessary to invent a die-cutting mold that can be quickly assembled and disassembled to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a die-cutting mold that can be quickly assembled and disassembled. By setting rectangular holes and rectangular slots, and cooperating with rectangular chucks and rectangular turntables, the mold can be quickly connected to the mounting base. By rotating the mold to align the rectangular turntable and rectangular chuck, the mold can be quickly separated from the mounting base. This achieves quick assembly and disassembly of the mold, solving the problem of inconvenient maintenance and replacement in the later stages of traditional bolt connections.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly die, comprising: A mounting base and a mold disposed above the mounting base, wherein the inner wall of the mounting base is provided with a through hole; A positioning mechanism includes a fixed shaft, one end of which is fixedly connected to the top of a mounting base, and the other end of which is fixedly connected to a rectangular chuck. A rectangular turntable is rotatably connected to the outer wall of the fixed shaft. A rectangular groove is provided on the inner wall of the mold, and a rectangular hole is provided at the bottom of the mold. A sliding plate is slidably connected to the inner wall of the mounting base. A limit shaft is fixedly connected to the upper surface of the sliding plate, and a spring is sleeved on the outer wall of the limit shaft. A limit hole is provided at the bottom of the rectangular turntable.
[0007] Preferably, one end of the spring is fixedly connected to the top of the inner wall of the mounting base, and the other end of the spring is fixedly connected to the upper surface of the slide plate.
[0008] Preferably, the rectangular turntable is engaged with the inner wall of the rectangular hole, and the rectangular turntable and the rectangular chuck are exactly the same size.
[0009] Preferably, the inner diameter of the limiting hole is equal to the outer diameter of the limiting shaft, and the limiting shaft is inserted into the inner wall of the limiting hole.
[0010] Preferably, the lower surface of the rectangular chuck is in contact with the bottom of the inner wall of the rectangular groove, and the bottom of the mold is in contact with the upper surface of the mounting base.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the design of a positioning mechanism, allows for disassembly or installation of the mold simply by rotating it, without the need for tools. Compared to traditional bolt connections, this not only improves the efficiency of mold assembly and disassembly and facilitates subsequent replacement, but also provides stable support for the mold after installation, thereby ensuring the stability of the mold during use.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0016] This utility model provides, for example Figure 1 - Figure 4 The illustrated die-cutting mold includes a mounting base 1, a mold 2, and a positioning mechanism 4. The inner wall of the mounting base 1 has a through hole 3, and the mounting base 1 can be fixed on the machine base by passing the bolt through the through hole 3; The positioning mechanism 4 includes a fixed shaft 41, one end of which is fixedly connected to the top of the mounting base 1, and the other end of which is fixedly connected to a rectangular chuck 42. The rectangular chuck 42, in conjunction with a rectangular groove 45, can limit the mold 2 to the top of the mounting base 1. A rectangular turntable 43 is rotatably connected to the outer wall of the fixed shaft 41. A rectangular groove 45 is provided on the inner wall of the mold 2, and a rectangular hole 44 is provided on the bottom of the mold 2. The rectangular hole 44 allows the rectangular turntable 43 to enter and exit the rectangular groove 45 for disassembly and assembly of the mold 2. A sliding plate 46 is slidably connected to the inner wall of the mounting base 1. A limiting shaft 47 is fixedly connected to the upper surface of the sliding plate 46. The rectangular turntable 43 can be limited by the sliding plate 46 in conjunction with the limiting shaft 47 and the limiting hole 49. A spring 48 is sleeved on the outer wall of the limiting shaft 47, and a limiting hole 49 is provided on the bottom of the rectangular turntable 43.
[0017] like Figure 3 As shown, one end of the spring 48 is fixedly connected to the top of the inner wall of the mounting base 1, and the other end of the spring 48 is fixedly connected to the upper surface of the slide plate 46. The elasticity of the spring 48 can drive the slide plate 46 to slide upward and reset, so that the slide plate 46 can drive the limiting shaft 47 to insert into the limiting hole 49.
[0018] like Figure 2 - Figure 3 As shown, the rectangular turntable 43 is snapped into the inner wall of the rectangular hole 44. The rectangular turntable 43 and the rectangular chuck 42 are exactly the same size. The rectangular chuck 42 can enter and exit the rectangular slot 45 through the rectangular hole 44. The rectangular hole 44 limits the rectangular turntable 43, so that when the mold 2 is rotated, the rectangular turntable 43 can be driven to rotate on the outer wall of the fixed shaft 41.
[0019] like Figure 3As shown, the inner diameter of the limiting hole 49 is equal to the outer diameter of the limiting shaft 47. The limiting shaft 47 is inserted into the inner wall of the limiting hole 49. By using the limiting shaft 47 in conjunction with the limiting hole 49, the rectangular turntable 43 can be limited, preventing it from rotating on the outer wall of the fixed shaft 41.
[0020] like Figure 3 As shown, the lower surface of the rectangular chuck 42 is in contact with the bottom of the inner wall of the rectangular groove 45. The contact between the bottom of the rectangular chuck 42 and the bottom of the inner wall of the rectangular groove 45 can limit the axial movement of the mold 2, thereby fixing the mold 2 on the top of the mounting base 1. The bottom of the mold 2 is in contact with the upper surface of the mounting base 1.
[0021] The working principle of this utility model is as follows: By passing the bolt through the through hole 3, the mounting base 1 can be fixed on the machine. When it is necessary to disassemble and replace the mold 2, first press down on the sliding plate 46, so that the sliding plate 46 slides down on the inner wall of the mounting base 1. As the sliding plate 46 slides down, it will stretch the spring 48 and drive the limiting shaft 47 to be pulled out from the inside of the limiting hole 49. This will release the limiting shaft 47 from limiting the rectangular turntable 43. At this time, the mold 2 can be rotated. During the rotation of the mold 2, under the limiting action of the rectangular hole 44 opened in its inner wall, the mold 2 will drive the rectangular turntable 43 to rotate synchronously on the outer wall of the fixed shaft 41. When the rectangular turntable 43 rotates to completely overlap with the rectangular chuck 42, the rectangular chuck 42 at the top of the fixed shaft 41 will be completely aligned with the rectangular hole 44. Then lift the mold 2 up to move the rectangular turntable 43 out from the inside of the rectangular hole 44. At the same time, the rectangular chuck 42 will move out of the rectangular slot 45 through the rectangular hole 44. In this way, the mold 2 can be separated from the mounting base 1. Thus, the disassembly of the mold 2 is completed.
[0022] When installing the replaced mold 2, first rotate the rectangular turntable 43 to fully align it with the rectangular chuck 42. Then, align the rectangular hole 44 with the rectangular chuck 42 and press the mold 2 downwards, causing the rectangular chuck 42 to insert into the rectangular groove 45 through the rectangular hole 44. Simultaneously, the rectangular turntable 43 will insert into the rectangular hole 44. Rotating the mold 2, in conjunction with the limiting action of the rectangular hole 44, will cause the rectangular turntable 43 to rotate synchronously on the outer wall of the fixed shaft 41. The rotation of the mold 2 will cause the rectangular turntable 43 to be misaligned with the rectangular chuck 42, thus misaligning the rectangular chuck 42 with the rectangular hole 44. This allows the bottom of the rectangular chuck 42 to fit against the bottom of the inner wall of the rectangular groove 45. When the rectangular turntable 43 rotates, causing the limiting hole 49 on its inner wall to align with the limiting shaft 47, the previously stretched spring 48 will pull the slide plate 46 upward, causing the slide plate 46 to slide upward and reset on the inner wall of the mounting base 1. At the same time, the slide plate 46 will drive the limiting shaft 47 to re-insert into the limiting hole 49. At this time, the limiting shaft 47 and the limiting hole 49 can limit the rectangular turntable 43, preventing it from rotating on the outer wall of the fixed shaft 41, thus preventing the mold 2 from rotating. Meanwhile, the bottom of the rectangular chuck 42 fits against the bottom of the inner wall of the rectangular groove 45, which can axially limit the mold 2, thereby fixing the mold 2 on the top of the mounting base 1. Thus, the installation of the mold 2 is completed.
[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
