Description

Technical Field

[0001] This utility model relates to the field of laser die-cutting technology, specifically to a laser die-cutting mold that is easy to cool. Background Technology

[0002] Laser die cutting is an industrial mold that uses stamping to cut specific shapes. It uses a laser to ablate the substrate to create the blade mounting gap, achieving precision cutting. It is widely used in industries such as printing and packaging, electronic materials, leather products, and automobile manufacturing, and is especially suitable for high-precision applications such as cardboard box model cutting and self-adhesive label die cutting.

[0003] Traditional laser die-cutting molds dissipate heat through methods such as thermally conductive adhesive / pads and snap-fit ​​tracks, but this cannot guarantee uniform heat dissipation, resulting in localized overheating of the die-cutting mold. This leads to uneven thermal expansion of the die-cutting mold, reduced accuracy of the cutting path, and accelerated aging of the die-cutting mold material. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a laser die-cutting mold that is easy to cool, and has the advantage of uniform heat dissipation, thus solving the problem of uneven heat dissipation and localized overheating of the die-cutting mold.

[0006] Technical solution

[0007] To achieve the aforementioned goal of uniform heat dissipation for the die-cutting mold, this utility model provides the following technical solution: It includes a housing, with a cutting assembly installed on the top of the inner wall of the housing, a cooling assembly installed at the bottom of the cutting assembly, a fixing assembly installed on the left side of the housing, and the cooling assembly including a copper plate fixedly connected to the bottom of the cutting assembly. A copper pipe is installed on the bottom surface of the copper plate, and the bottom surface of the copper plate is in close contact with the top surface of the copper pipe. A water tank is located on the right outer wall of the housing, a water pump is installed on the front of the water tank, one end of the copper pipe is fixedly connected to the output end of the water pump, and the other end of the copper pipe is fixedly connected to the back of the water tank. Three water-cooling fans are equidistantly installed on the top of the water tank.

[0008] As a further embodiment of this utility model: the outer wall of the copper tube is fitted with a plurality of fixing collars, and the bottom of the fixing collars is fixedly connected to the box body.

[0009] As a further embodiment of this utility model: the cutting assembly includes a mounting plate installed on the top of the inner wall of the box, and the top of the mounting plate has two rectangular blade slots symmetrically formed, and a rectangular blade is engaged with the inner wall of each rectangular blade slot.

[0010] As a further embodiment of this utility model: two first sliding grooves are symmetrically formed on the top inner wall of the box, and the inner wall of the first sliding groove is slidably connected to the outer wall of the mounting plate.

[0011] As a further embodiment of this utility model: the fixing component includes an installation groove formed inside the left side of the housing, an installation column fixedly connected inside the installation groove, a spring sleeved on the outer wall of the installation column, an L-shaped insert mounted on the top surface of the spring, the inner wall of the L-shaped insert slidingly connected to the outer wall of the installation column, a protrusion fixedly connected to the left side of the L-shaped insert, a second sliding groove formed on the left side of the housing, the protrusion slidingly connected to the inner wall of the second sliding groove, and a slot formed on the bottom left side of the mounting plate, the slot being inserted into the L-shaped insert.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model provides a laser die-cutting mold that is convenient for cooling, and has the following beneficial effects:

[0015] 1. This laser cutting die, which is easy to cool, absorbs the heat generated by the blade cutting through a copper plate. Then, through the large-area contact between the copper plate and the copper tube, the heat is carried away by the circulation of coolant in the copper tube. At the same time, a water-cooled fan cools the coolant flowing back to the water tank, forming a multi-stage cooling system. This improves the service life and working stability of the cutting die and avoids the problem of local overheating damage to the cutting die that leads to a decrease in cutting accuracy.

[0016] 2. This laser cutting die, which facilitates cooling, employs a combination of a spring and an L-shaped insert. By pushing the protrusion downwards to move the L-shaped insert away from the slot, and then sliding the mounting plate to the corresponding position, the protrusion is released. Under the action of the spring force, the L-shaped insert is inserted into the slot, which can stably fix the mounting plate and prevent it from moving during the cutting process, thus ensuring the accuracy and quality of the cutting.

[0017] 3. This laser cutting die, which is easy to cool, has a compact layout of cooling, cutting and fixing components working together to achieve both cutting and cooling functions, while ensuring the overall stability and reliability of the equipment. It also allows for quick replacement and maintenance in case of cooling failure. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-3 A laser die-cutting mold with convenient cooling includes a housing 1. A cutting component 2 is installed on the top of the inner wall of the housing 1, and a cooling component 3 is installed on the bottom of the cutting component 2. A fixing component 5 is installed on the left side of the housing 1. The cutting component 2 includes a mounting plate 201 installed on the top of the inner wall of the housing 1. Two rectangular cutting grooves 202 are symmetrically opened on the top of the mounting plate 201. A rectangular blade 203 is snapped into the inner wall of each rectangular cutting groove 202. Two first sliding grooves 4 are symmetrically opened on the top inner wall of the housing 1. The inner wall of the first sliding groove 4 is slidably connected to the outer wall of the mounting plate 201. A handle 6 is fixedly connected to the right outer wall of the mounting plate 201, which allows for quick installation and disassembly of the die-cutting mold and the housing 1, facilitating equipment maintenance.

[0025] Please see Figure 1-3The cooling assembly 3 includes a copper plate 301 fixedly connected to the bottom of the mounting plate 201. A copper pipe 302 is installed on the bottom surface of the copper plate 301. A water tank 305 is provided on the right outer wall of the housing 1. A water pump 304 is installed on the front of the water tank 305. One end of the copper pipe 302 is fixedly connected to the output end of the water pump 304, and the other end of the copper pipe 302 is fixedly connected to the back of the water tank 305. Three water-cooled fans 306 are equidistantly installed on the top of the water tank 305. The outer wall of the copper pipe 302... Multiple retaining rings 303 are snapped together. The coolant in the water tank 305 flows through the copper pipe 302 via the water pump 304. After the coolant returns to the water tank 305, the water-cooled fan 306 quickly cools the coolant that has returned to the water tank 305 to complete the circulation and heat dissipation. Then, the copper plate 301 and the copper pipe 302 make large-area close contact, so that the die can dissipate heat evenly and improve the heat dissipation efficiency. This avoids the die from local overheating, which would reduce the accuracy of the cutting path and accelerate the aging of the die material.

[0026] Please see Figure 1-4 The fixing component 5 includes a mounting groove 501 formed inside the left side of the housing 1. A mounting post 502 is fixedly connected inside the mounting groove 501. A spring 503 is sleeved on the outer wall of the mounting post 502. An L-shaped insert 504 is mounted on the top surface of the spring 503. The inner wall of the L-shaped insert 504 is slidably connected to the outer wall of the mounting post 502. A protrusion 505 is fixedly connected to the left side of the L-shaped insert 504. A second sliding groove 506 is formed on the left side of the housing 1. The protrusion 505 and... The inner wall of the second groove 506 is slidably connected. A slot 507 is provided on the bottom left side of the mounting plate 201. The slot 507 is inserted into the L-shaped plug 504. The upward pushing force generated by the spring 503 causes the L-shaped plug 504 to be inserted into the slot 507. Under the elastic force of the spring 503, the L-shaped plug 504 is inserted into the slot 507, which can stably fix the mounting plate 201 and prevent the mounting plate 201 from moving during the cutting process, thus ensuring the accuracy and quality of the cutting.

[0027] Working principle: First, press the protrusion 505 by hand to move the L-shaped insert 504 downward, and move the mounting plate 201 to the corresponding position through the first sliding groove 4. Then, release the protrusion 505, and under the elastic force of the spring 503, the L-shaped insert 504 is inserted into the slot 507, so that the mounting plate 201 can be firmly fixed. After fixing, the copper plate 301 can contact the copper pipe 302 over a large area. The copper plate 301 can quickly absorb the heat generated by the cutting component 2. After the water pump 304 is started, the coolant in the water tank 305 flows in the copper pipe 302, absorbing the heat transferred by the copper plate 301. After the coolant flows back to the water tank 305 through the copper pipe 302, the water cooling fan 306 quickly cools the coolant that flows back to the water tank 305, ensuring the cooling effect of the coolant and realizing circulating heat dissipation.

[0028] When it is necessary to disassemble or replace the die, press the protrusion 505 with your hand to move the L-shaped insert 504 away from the slot 507, and then pull the handle 6 to move the mounting plate 201 to complete the disassembly.
