In the packaging industry, corrugated paper is widely used due to its lightweight, low cost, and good cushioning properties. Die-cutting machine molds, through precise cutting and creasing operations, process corrugated paper into various shapes to meet the packaging needs of different products. With the rapid development of e-commerce and logistics, the demand for corrugated paper packaging has surged. High-precision, durable die-cutting machine molds effectively improve production efficiency and ensure the quality of corrugated paper packaging, occupying an important position in the packaging industry chain.

[0003] Most existing corrugated paper die-cutting machine molds have fixed structures, making it difficult to adjust the molds flexibly. For corrugated paper of different thicknesses, the distance between the cutting blade and the bending blade cannot be adjusted, resulting in inaccurate cutting and bending. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for a corrugated paper die-cutting machine, so as to solve the problem that most existing corrugated paper die-cutting machine molds in the above-mentioned background art have fixed structures, making it difficult to flexibly adjust the templates. For corrugated paper of different thicknesses, the distance between the cutting blade and the bending blade cannot be adjusted, resulting in inaccurate cutting and bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for a corrugated paper die-cutting machine, comprising an upper template and a lower template disposed on the lower side of the upper template;

[0006] Multiple bending blades are provided on the upper side of the lower template, and multiple cutting blades are provided on the upper side of the upper template.

[0008] Preferably, a pressure groove is provided at the connection position between the cutting blade and the upper template, and the height of the plurality of cutting blades is greater than the height of the bending blade.

[0009] Preferably, multiple positioning holes are provided in the middle of the inner sides of the upper and lower templates, and the positions of the positioning holes in the upper template and the lower template coincide.

[0010] Preferably, the blind hole opening of the blind hole nut faces the lower template, and the blind hole nut is fixedly connected to the upper template.

[0011] Preferably, the adjusting bolt rod is connected to the blind hole in the blind hole nut and the threaded hole in the lower template respectively through threaded connections, and the adjusting bolt rod can move up and down in the blind hole nut through the threads.

[0012] Preferably, the upper and lower templates have the same volume and thickness, and both the upper and lower templates are made of metal.

[0013] Compared with the prior art, this utility model provides a mold for a corrugated paper die-cutting machine, which has the following advantages:

[0014] The distance between the upper and lower templates can be easily changed by rotating the adjusting bolt rod, thereby adjusting the distance between the bending knife and the cutting knife. This allows for precise adaptation to the processing needs of corrugated paper of different thicknesses, greatly improving the applicability and processing flexibility of the mold and reducing the number of defective products caused by mold mismatch.

[0015] The corrugated paper is placed in a specific position on the lower template, and the die-cutting machine drives the upper template to move downward. The cutting blade and bending blade work in sequence, and the entire processing flow is completed in one go, ensuring the accuracy and efficiency of corrugated paper processing and meeting the needs of large-scale production.

[0016] The upper and lower templates are positioned and installed using positioning holes and positioning pins, which greatly improves the accuracy and efficiency of mold assembly, reduces the mold debugging time caused by installation errors, and enables the mold to be put into use quickly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 The mold shown is for a corrugated paper die-cutting machine, including an upper template 1 and a lower template 2 disposed on the lower side of the upper template 1;

[0026] Multiple bending blades 5 are provided on the upper side of the lower template 2, and multiple cutting blades 3 are provided on the upper side of the upper template 1.

[0027] Blind hole nuts 7 are provided at the lower corners of the upper template 1. Threaded holes 9 are provided on the lower side of the lower template 2 at the positions corresponding to the blind hole nuts 7. Adjusting bolt rods 6 are provided on the inner side of the threaded holes 9.

[0028] In this embodiment, the user first installs the assembled mold at the designated position below the stamping equipment. During installation, multiple positioning holes 4 are used for positioning on the inner sides of the upper template 1 and the lower template 2. The positioning pin is inserted into the corresponding positioning hole of the stamping equipment, and then the positioning hole 4 of the mold is aligned with the positioning pin and slowly lowered to ensure that the mold is accurately installed on the stamping equipment, avoiding displacement during the stamping process and affecting the processing accuracy.

[0029] After the mold is installed and positioned, place the corrugated paper to be processed onto the mold. Carefully adjust the position of the corrugated paper to precisely align with the working positions of the bending blade 5 on the lower template 2 and the corresponding cutting blade 3 on the upper template 1. Auxiliary positioning markers or devices can be installed on the mold to help operators place the corrugated paper more quickly and accurately.

[0030] Depending on the actual thickness of the corrugated paper, the distance between the upper template 1 and the lower template 2 is changed by rotating the adjusting bolt 6. If the corrugated paper is thicker, rotating the adjusting bolt 6 counterclockwise raises the upper template 1 relative to the lower template 2, increasing the distance between the bending blade 5 and the cutting blade 3; if the corrugated paper is thinner, rotating the adjusting bolt 6 clockwise lowers the upper template 1 relative to the lower template 2, decreasing the distance between them, thus adapting to the processing needs of corrugated paper of different thicknesses.

[0031] After completing the above preparations, start the stamping equipment. The upper template 1 moves rapidly downwards under the drive of the stamping equipment. The cutting blade 3 first contacts the corrugated paper, using the pressure of the stamping equipment to cut the corrugated paper. As the upper template 1 continues to descend, the bending blade 5 contacts the corrugated paper and bends it. In one complete stamping stroke of the stamping equipment, the cutting and bending of the corrugated paper is completed.

[0032] like Figure 1-6 As shown, a pressure groove 8 is provided at the connection position between the cutting blade 3 and the upper template 1. The height of multiple cutting blades 3 is greater than the height of the bending blade 5. Multiple positioning holes 4 are opened in the middle of the inner side of the upper template 1 and the lower template 2. The positions of the positioning holes 4 in the upper template 1 and the lower template 2 coincide. The blind hole nut 7 has its blind hole opening facing the lower template 2. The blind hole nut 7 is fixedly connected to the upper template 1. The adjusting bolt rod 6 is connected to the blind hole in the blind hole nut 7 and the threaded hole 9 in the lower template 2 through threaded connection. The adjusting bolt rod 6 can move up and down in the blind hole nut 7 through the thread. The upper template 1 and the lower template 2 have the same volume and thickness. The upper template 1 and the lower template 2 are both made of metal.

[0033] Preferably, the user can use a wrench or other tools to rotate the adjusting bolt rod 6 according to the thickness of the corrugated paper to be processed. When the corrugated paper is thicker, rotating the adjusting bolt rod 6 counterclockwise causes it to move upward within the blind hole nut 7 due to the threaded connection between the adjusting bolt rod 6 and the blind hole nut 7, which in turn causes the lower template 2 to descend relative to the upper template 1, increasing the distance between the bending blade 5 and the cutting blade 3. When the corrugated paper is thinner, rotating the adjusting bolt rod 6 clockwise causes it to move downward within the blind hole nut 7, causing the lower template 2 to rise relative to the upper template 1, thus decreasing the distance between the bending blade 5 and the cutting blade 3.

[0034] By utilizing the characteristics of threaded connections, the rotational motion is converted into linear motion by rotating the adjusting bolt rod 6, thereby precisely changing the relative position between the upper template 1 and the lower template 2. This allows for adjustment of the distance between the folding blade 5 and the cutting blade 3, adapting to the processing requirements of corrugated paper of different thicknesses. This adjustment method is simple to operate and has controllable precision.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
