Description

Technical Field

[0001] This utility model relates to the field of laser die-cutting technology, specifically to high-precision laser die-cutting. Background Technology

[0002] In today's booming cardboard processing industry, cardboard cutting dies are the core components for achieving precise cutting. Their performance directly affects the accuracy and quality of cardboard cutting, and thus plays a decisive role in the quality of the final product. Currently, in the manufacturing process of cardboard cutting dies, using laser cutting technology to create grooves in the template that carries the cutting tools to install them is a widely adopted standard operating procedure in the industry.

[0003] Laser cutting is widely used in the production of cardboard cutting molds. In the initial stage, the laser beam energy is concentrated and stable, and the cutting deviation is small. However, as the cutting progresses, on the one hand, the laser energy is lost due to absorption and reflection by the optical path lenses, resulting in uneven distribution; on the other hand, the template material continuously absorbs heat, exacerbating thermal deformation. In addition, the overall template structure makes it difficult to release thermal stress. As the cutting depth increases, thermal stress accumulates, and the cutting area deforms severely, causing the groove slope to increase due to the increased laser cutting deviation.

[0004] The significant increase in the blade groove angle directly leads to the difficulty in ensuring the perpendicularity of the blade after installation. In the cardboard cutting process, the deviation in blade perpendicularity can easily cause problems such as uneven cuts and dimensional errors exceeding the allowable range when cutting cardboard, which seriously affects product quality.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a high-precision laser die-cutting mold to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a high-precision laser cutting mold, including a template and a cutting tool mounted thereon. The template is formed by stacking a first template and a second template with the same shape and specifications. A cutting groove is formed on the template, which runs vertically through its thickness direction. The cutting tool is installed inside the cutting groove. The cutting groove includes a first straight groove formed through the first template and a second straight groove formed through the second template. The first straight groove and the second straight groove are aligned with each other. A first extension groove is formed on the groove surface of the first straight groove near the second straight groove, and a second extension groove is formed on the groove surface of the second straight groove near the first straight groove.

[0008] Furthermore, the thickness of both the first template and the second template is 9cm.

[0009] Furthermore, both the first template and the second template are made of wood.

[0010] Furthermore, the gap formed by the first extension groove and the second extension groove is double-conical.

[0011] Furthermore, the corners of the template are rounded.

[0012] Furthermore, the first template and the second template are fixed together by connecting bolts, and multiple connecting bolts are provided.

[0013] Furthermore, the second template has a through hole, and the first template has a threaded blind hole. The connecting bolt is inserted into the through hole and threaded into the inside of the threaded blind hole.

[0014] Furthermore, the cutting tool has a blunt edge and a sharp edge. The plane containing the blunt edge is on the same plane as one side of the template, so that the two are flush. The sharp edge protrudes from the other side of the template, with a protrusion height of 1.5cm.

[0015] Furthermore, the depth of the groove is adapted to the length from the blunt edge to the sharp edge of the cutting tool.

[0016] Furthermore, the minimum width of the cutting groove is adapted to the thickness of the cutting tool.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model disassembles the traditional monolithic template into a first template and a second template of the same shape and specifications, which are then stacked together. When laser cutting the groove, the laser acts on the two templates separately, thus dispersing the thermal stress. Because the area of ​​each template is reduced, the degree of thermal deformation generated during laser cutting is reduced, thereby reducing the groove slope. When the laser cuts the first straight groove of the first template, the generated thermal stress is limited to the first template and the second template is unaffected, and vice versa. This effectively solves the problem of increased groove slope caused by increased laser cutting depth, improves the verticality of the cutter after installation, and thus significantly improves the paperboard cutting accuracy and reduces the defect rate caused by cutting accuracy issues.

[0019] 2. In this utility model, the first straight groove and the second straight groove on the two templates are aligned to form a complete cutting groove, and the first extension groove and the second extension groove further reduce the contact area between the cutting groove and the cutting tool, thereby reducing the impact of the cutting groove on the cutting tool.

[0026] 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a high-precision laser cutting mold, including a template and a cutting tool 4 mounted thereon. The template is formed by stacking a first template 1 and a second template 2 with the same shape and specifications. A cutting groove is formed on the template, which is perpendicular to its thickness direction. The cutting tool 4 is installed inside the cutting groove. The cutting groove includes a first straight groove formed through the first template 1 and a second straight groove formed through the second template 2. The first straight groove and the second straight groove are aligned with each other. A first extension groove 5 is formed on the groove surface of the first straight groove near the second straight groove, and a second extension groove 6 is formed on the groove surface of the second straight groove near the first straight groove.

[0028] Specifically, the template is composed of a first template 1 and a second template 2 stacked together, and the cutting groove is formed by the mating of a first straight groove penetrating the first template 1 and a second straight groove penetrating the second template 2. During cutting, the laser acts on both templates separately. Compared to cutting the entire template, this disperses thermal stress, reduces template deformation, and thus reduces the cutting groove angle. The first extension groove 5 and the second extension groove 6 reduce the contact area between the cutting groove and the cutting tool 4, minimizing the impact of the cutting groove on the cutting tool 4. This effectively solves the problem of increased cutting groove angle caused by increased laser cutting depth, improves the verticality of the cutting tool 4 after installation, and thus improves the paperboard cutting accuracy. Reducing the contact area between the cutting groove and the cutting tool 4 also reduces wear on the cutting tool 4 and extends its service life.

[0029] See Figure 1Both the first template 1 and the second template 2 are 9cm thick and are made of wood.

[0030] See Figure 5 The gap formed by the first extension groove 5 and the second extension groove 6 is double-conical.

[0031] See Figure 1 The corners of the template are rounded.

[0032] See Figure 1 The first template 1 and the second template 2 are fixed together by connecting bolts 3, and multiple connecting bolts 3 are provided.

[0033] Specifically, it can tightly and firmly connect two templates together, ensuring that the two templates maintain a stable relative position during the cutting process, and that the alignment accuracy of the cutting groove is not affected, thus ensuring the stability of the template stacking structure, maintaining the accuracy of the cutting groove, and thus ensuring the accuracy of the installation of the cutting tool 4 and the high precision of the cutting.

[0034] See Figure 4 The second template 2 has a through hole, and the first template 1 has a threaded blind hole. The connecting bolt 3 is inserted into the through hole and threaded into the inside of the threaded blind hole.

[0035] Specifically, this connection method facilitates installation and disassembly, and makes the operation simple when the template or cutting tool 4 needs maintenance or replacement. It improves the maintainability and replaceability of the die, reduces maintenance costs, shortens maintenance time, and improves production efficiency.

[0036] See Figure 4 The cutting tool 4 has a blunt edge and a sharp edge. The blunt edge is on the same plane as one side of the template, so that the two are flush. The sharp edge protrudes from the other side of the template, with a protrusion height of 1.5cm.

[0037] Specifically, the blunt edge is flush with the template to ensure the stability of the blade 4 installation, while the sharp edge protrudes to a specific height to effectively cut into the cardboard. This ensures that the blade 4 can be stably fixed on the template during the cutting process, and can also efficiently cut the cardboard at a suitable protrusion height, thereby improving cutting quality and efficiency.

[0038] See Figure 5 The depth of the groove is adapted to the length from the blunt edge to the sharp edge of the tool.

[0039] Specifically, this allows the cutting tool 4 to be precisely installed in the cutting groove, ensuring that the cutting tool 4 is firmly installed and that the height of the sharp edge of the cutting tool 4 protruding from the template meets the design requirements, thus ensuring the accuracy of the installation of the cutting tool 4 and guaranteeing the cutting precision. At the same time, it optimizes the fit between the cutting tool 4 and the cutting groove, extending the service life of the cutting tool 4 and the die.

[0040] See Figure 5 The minimum width of the groove is adapted to the thickness of the tool 4.

[0041] Specifically, the minimum width of the cutting groove is matched with the thickness of the cutting tool 4 to ensure that the cutting tool 4 can be tightly installed in the cutting groove, prevent the cutting tool 4 from shaking in the cutting groove, ensure the stability of the cutting tool 4 during the cutting process, improve the stability of the installation of the cutting tool 4, and thus improve the accuracy and quality of cardboard cutting.

[0042] Working Principle: The traditional monolithic template is split into two identical templates, a first template 1 and a second template 2, which are then stacked together. During laser cutting, the laser acts on both templates separately, dispersing thermal stress. Because the area of ​​each template is reduced, the degree of thermal deformation during laser cutting is decreased, thus reducing the slope of the groove. When the laser cuts the first straight groove of the first template 1, the generated thermal stress is limited to the first template 1, and the second template 2 is unaffected, and vice versa. The first and second straight grooves on the two templates align to form a complete groove, and the first extension groove 5 and the second extension groove 6 further reduce the contact area between the groove and the cutting tool 4, reducing the impact of the groove on the cutting tool 4. The first template 1 and the second template 2 are fixed by multiple evenly distributed connecting bolts 3, ensuring a tight and secure connection between the two templates. The through holes on the second template 2 mate with the threaded blind holes on the first template 1. The connecting bolts 3 pass through the through holes and are threaded into the threaded blind holes. This connection method ensures the relative position of the two templates is stable during cutting and facilitates installation and disassembly, making subsequent maintenance and replacement convenient.

Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
