[0002] With the development of social economy and the improvement of people's living standards, more and more products are being manufactured, many of which are made by cutting dies, which are widely used in industrial production.

[0003] The so-called die cutter is the die for punching products, which can also be called a punching die. For example, a box is a flat paper when it is printed. After printing, it is necessary to make a flat die with the same shape as the box to punch and shape it. This die is the printing die cutter. The die cutter can be divided into: laser die cutter, engraving die cutter, cutting die cutter, printing die cutter, etching die cutter, wood laser die cutter, die cutting die cutter, electronic laser die cutter, plastic board laser die cutter, FPC laser die cutter and waste removal die cutter, etc.

[0004] The current die cutter generally has a structure in which a die cutter is directly set on a die base. Although this die cutter has a simple structure and can basically realize the cutting function, the size of the die cutter in this die cutter is fixed and cannot be adjusted. If you want a different cutting size, you need to make a different die cutter again. Remaking the die cutter requires a lot of materials, manpower, and time, and the production cost is very high, which brings inconvenience to production. It is not flexible enough to use and cannot meet existing needs. Therefore, it is necessary to study a new technical solution to improve the above problems. Utility Model Content

[0028] Please refer to Figures 1 to 3As shown, it shows the specific structure of the preferred embodiment of the utility model, including four connecting parts 10, four die cutters 20, four fixing plates 30 and four first screws 40.

[0029] The four connecting members 10 are arranged in front, back, left and right directions and surround a accommodating cavity 101. A slide groove 11 is recessed inwardly on the side surface of each connecting member 10, and the slide groove 11 is extended laterally. A slider 12 is convex outwardly at one end of each connecting member 10. The slider 12 on each connecting member 10 is arranged in the slide groove 11 on the adjacent connecting member 10 and can move back and forth along the slide groove 11; in this embodiment, a second threaded hole 13 is arranged on the upper surface of each connecting member 10 near one end of the slider 12; the connecting member 10 is made of aluminum, which has a low density, is light, has good corrosion resistance, can improve the quality of the product, extend the service life of the product, and is more durable; the connecting member 10 is square; the slide groove 11 is circular, and correspondingly, the slider 12 is also circular.

[0030] The four die-cutting knives 20 are respectively arranged on the corresponding connecting parts 10 and are located below the corresponding slide grooves 11, and the four die-cutting knives 20 all extend downward from the corresponding connecting parts 10; in the present embodiment, the die-cutting knife 20 is made of stainless steel, which has high hardness, high strength and good corrosion resistance, making the product more sturdy and durable; the die-cutting knife 20 is a single-edged knife.

[0031] The four fixing plates 30 are respectively arranged between two corresponding adjacent connecting members 10, and each fixing plate 30 includes a first extension portion 31 and a second extension portion 32 bent downward and extending from the first extension portion 31. The first extension portion 31 is fixedly arranged at one end of a connecting member 10 close to the slider 12, and the second extension portion 32 and the connecting member 10 are surrounded to form a positioning groove 301. The adjacent connecting members 10 can be movably arranged back and forth in the positioning groove 301, and a first threaded hole 321 is formed through the second extension portion 32; in this embodiment, a through hole 311 is formed through the upper and lower surfaces of the first extension portion 31, and four second screws 50 are further arranged. The four second screws 50 respectively pass through the corresponding through holes 311 and are threadedly connected and fixed with the corresponding second threaded holes 13, which effectively enhances the stability of the connection structure and is convenient and quick to assemble.

[0032] The four first screws 40 can be respectively locked or loosened in the corresponding first threaded holes 321. When the four first screws 40 are loosened, the slider 12 on each connecting member 10 can move back and forth along the slide groove 11 on the adjacent connecting member 10 to adjust the cutting size of the die. After the cutting size is adjusted, the four first screws 40 can be locked to fix the four connecting members 10 to prevent the die size from moving. The operation is simple and the structure is more stable and reliable.

[0033] The manufacturing, assembly and use process of this embodiment are described in detail as follows:

[0034] First, prepare four connecting members 10, four die cutters 20, four fixing plates 30, four first screws 40 and four second screws 50; then, install the four die cutters 20 under the corresponding slide grooves 11 of the connecting members 10; then, install the slider 12 on each connecting member 10 into the slide groove 11 on the adjacent connecting member 10, and arrange the four connecting members 10 front, back, left and right to form a receiving cavity 101; then, the four second screws 50 pass through the corresponding through holes 311 and are threadedly connected with the corresponding second threaded holes 13 to fix the fixing plates 30; finally, install the four first screws 40 into the corresponding first threaded holes 321 of the fixing plates 30.

[0035] When in use, according to different needs, the cutting size of the cutting die can be adjusted by moving the slider 12 of the connecting member 10 back and forth along the slide groove 11 of the adjacent connecting member 10. After adjusting the size, tighten the four first screws 40 on the side of the corresponding connecting member 10 to prevent the cutting die from moving. The next step is to install the cutting die on the machine for cutting operations.
