Description

Technical Field

[0001] This utility model relates to the field of automotive mold production technology, specifically a cutting device for automotive mold production. Background Technology

[0002] Automotive molds refer to molds used in the automotive field and are known as the "mother of the automotive industry". Automotive molds are generally divided into stamping molds, injection molds, forging molds, casting molds, etc., and according to automotive parts, they are divided into body panel molds, interior molds, structural component molds, etc.

[0003] During the cutting process of existing automotive molds, a large amount of heat is generated on the surface of the cut parts and the cutting blade due to factors such as long cutting time and high friction. The current solution is often to use natural air cooling, but some heat is too large to dissipate in time, which can cause local thermal stress deformation, thus affecting the condition of the automotive mold and the life of the cutting blade. Therefore, we propose a cutting device for automotive mold production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for automobile mold production to solve the problems mentioned in the background art.

[0006] Four sets of support columns are symmetrically fixed at the four corners of the bottom of the base plate. A support plate is fixed on the side of the four sets of support columns facing each other. A cooling assembly is installed on the top of the support plate.

The other end of the air pipe is installed with the cutting assembly.

[0007] Furthermore, a mechanical slide rail is fixed to the top of the base plate, and an mounting plate is slidably disposed inside the mechanical slide rail.

[0008] Furthermore, the cutting assembly includes a robotic arm fixed to the top of the mounting plate, a connecting arm fixed to the output end of the robotic arm, a groove opened at the bottom of the connecting arm, a cutter rotatably connected to the inner wall of the groove, and four sets of air jets symmetrically fixed on the left and right sides of the top of the inner wall of the groove, the four sets of air jets being equidistantly arranged on both sides of the cutter.

[0009] Furthermore, the clamping assembly includes four sets of fixing blocks symmetrically fixed to the bottom of the base plate. Two sets of fixing blocks on one side are rotatably connected to a bidirectional lead screw on their opposing sides. The outer wall of the bidirectional lead screw is symmetrically threaded with two sets of threaded blocks. A stop block is fixed at the center of the outer wall of the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a base plate, cooling components, etc., when the cutter cuts the car mold, the surface of the cutter will generate heat. At this time, the air pump is activated, and air is drawn into the air pump and then transferred to the heat exchanger through the connecting pipe.

[0022] 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.

[0023] Please see Figures 1-6 A cutting device for automobile mold production includes a base plate 1, and a cutting component 4 is installed on the top of the base plate 1. The main function of the cutting component 4 is to cut automobile molds.

[0024] Before use, it should be noted that the robotic arm 23 in the cutting assembly 4 is existing technology, and its specific working process will not be described in detail here. Next, the mechanical slide rail 13 set on the top of the base plate 1 also moves in conjunction with the robotic arm 23. The robotic arm 23 is mounted on the top of the mounting plate 9, and the sliding method of the mechanical slide rail 13 is also existing technology.

[0025] In this embodiment, a clamping assembly 3 is installed at the bottom of the base plate 1. The main function of the clamping assembly 3 is to fix the automobile mold. The clamping assembly 3 includes four sets of fixing blocks 18 symmetrically fixed at the bottom of the base plate 1. Two sets of fixing blocks 18 on one side are rotatably connected to a bidirectional lead screw 20 facing each other. Two sets of threaded blocks 19 are symmetrically threaded to the outer wall of the bidirectional lead screw 20. A stop block 22 is fixed in the middle of the outer wall of the bidirectional lead screw 20. A first synchronous pulley 14 is rotatably connected to the outer wall of a set of fixing blocks 18 on the right side. A second synchronous pulley 15 is rotatably connected to the outer wall of a set of fixing blocks 18 on the right side. The first synchronous pulley 14 and the second synchronous pulley 15 are connected by a synchronous belt. 16 Connection, a motor 17 is fixed to the right outer wall of the first synchronous pulley 14, the output end of the motor 17 is fixedly connected to the first synchronous pulley 14, the first synchronous pulley 14 is coaxially fixedly connected to a front double-acting screw 20, the second synchronous pulley 15 is coaxially fixedly connected to a rear double-acting screw 20, the top of the two sets of threaded blocks 19 on one side is fixedly connected to a U-shaped support column 7, the two sets of U-shaped support columns 7 are symmetrically fixed to the opposite side of the two sets of U-shaped support columns 7, the two sets of arc-shaped clamping blocks 10 are symmetrically fixed to the opposite side of the two sets of connecting rods 8, the top of the base plate 1 is symmetrically fixed to four sets of support blocks 12, and the top of the four sets of support blocks 12 is fixedly connected to an operating table 11;

[0026] Next, after placing the car mold on the operating table 11, the motor 17 is started. The motor 17 drives the first synchronous pulley 14 to rotate. It should be noted that the first synchronous pulley 14 drives the second synchronous pulley 15 to rotate synchronously via the synchronous belt 16. Then, four sets of fixing blocks 18 are designed at the bottom of the base plate 1. The main purpose of the fixing blocks 18 is to provide fixation. Two sets of bidirectional lead screws 20 are designed on the opposite side of the fixing blocks 18. The main function of the bidirectional lead screws 20 is to gradually bring the four sets of threaded blocks 19 on their outer walls closer together. It should be mentioned that the first synchronous pulley 14 and the second synchronous pulley 15 are respectively coaxially fixed to the bidirectional lead screws 20. Therefore… The movement of the four sets of threaded blocks 19 is synchronized. Then, a U-shaped support column 7 is designed on the top of the four sets of threaded blocks 19. A set of connecting rods 8 is designed on the facing side of the two sets of U-shaped support columns 7. The arc-shaped clamping block 10 is connected through the connecting rods 8. It should be noted that several sets of silicone blocks are installed on the arc-shaped surface of the arc-shaped clamping block 10. The silicone blocks are connected by springs on the back side. The main purpose of this design is that when the two sets of arc-shaped clamping blocks 10 approach each other, the silicone blocks can fit tightly with the car mold to prevent the car mold from falling off during cutting. After the car mold is fixed, the cutting of the car mold will begin.

[0027] In the above, four sets of support columns 6 are symmetrically fixed at the four corners of the bottom of the base plate 1. A support plate 5 is fixed on the side of the four sets of support columns 6 facing each other. A cooling component 2 is installed on the top of the support plate 5. The cooling component 2 is mainly used for local cooling of the blade during cutting. The cooling component 2 includes an air pump 27 fixed on the top right side of the support plate 5. A connecting pipe 26 is fixedly connected to the output end of the air pump 27. A heat exchanger 25 is fixedly connected to the left end of the connecting pipe 26. A pipe is fixed to the left end of the heat exchanger 25. A filter 29 is fixed to the left end of the pipe. An air pipe 24 is fixed to the rear outer wall of the filter 29. The other end of the air pipe 24 is installed with the cutting component 4. The cutting component 4 includes a mechanical arm 23 fixed on the top of the mounting plate 9. A connecting arm 30 is fixed to the output end of the mechanical arm 23. A groove is opened at the bottom of the connecting arm 30. A cutter 32 is rotatably connected to the inner wall of the groove. Four sets of air nozzles 31 are symmetrically fixed on the left and right sides of the top of the inner wall of the groove. The four sets of air nozzles 31 are equidistantly arranged on both sides of the cutter 32.

[0028] Specifically, after the car mold is fixed in place, the robotic arm 23 is activated, driving the cutter 32 to cut the car mold. It's worth noting that during the cutting process, the cutter 32 generates heat due to the prolonged cutting. This heat causes thermal stress deformation in both the car mold and the cutter 32. Therefore, when the cutter 32 starts working, the air pump 27 is simultaneously activated. The main function of the air pump 27 is to draw air into the interior and allow it to enter the heat exchanger 25 through the connecting pipe 26. Inside the heat exchanger 25, heat from the compressed air is removed by hot water or other media and transferred to the filter 29 through the expansion valve. Note that the compressed cold air is filtered in the filter 29, the main purpose of which is to remove solid particles and water from the compressed cold air to prevent these impurities from damaging the cutter 32 or the automotive mold. Finally, the compressed cold air will be discharged from the four sets of jet nozzles 31 near the cutter 32 to locally cool the outer edge of the cutter 32, remove the heat generated during the cutting process, and prevent thermal stress deformation.

[0029] Finally, after the cutting is completed, the motor 17 is restarted to release the fixation of the car mold and the cutter 32 is turned off, and the cut car mold is removed.

[0030] Working principle: After the car mold is placed on the operating table 11, the motor 17 is started. The motor 17 drives the first synchronous pulley 14 to rotate. It should be noted that the first synchronous pulley 14 drives the second synchronous pulley 15 to rotate synchronously via the synchronous belt 16. Next, four sets of fixing blocks 18 are designed at the bottom of the base plate 1. The main purpose of the fixing blocks 18 is to fix them. Two sets of bidirectional lead screws 20 are designed on the opposite side of the fixing blocks 18. The main function of the bidirectional lead screws 20 is to make the four sets of threaded blocks 19 on their outer walls gradually approach each other. It should be mentioned here that the first synchronous pulley 14 and the second synchronous pulley 15 rotate synchronously. The two synchronous pulleys 15 are coaxially fixed with the double-acting lead screw 20, so the movement of the four sets of threaded blocks 19 is synchronous. Then, a U-shaped support column 7 is designed on the top of the four sets of threaded blocks 19. A connecting rod 8 is designed on the facing side of the two sets of U-shaped support columns 7, and an arc-shaped clamping block 10 is connected through the connecting rod 8. It should be noted that several sets of silicone blocks are installed on the arc-shaped surface of the arc-shaped clamping block 10, and the rear side of the silicone blocks is connected by a spring. The main purpose of this design is to ensure that when the two sets of arc-shaped clamping blocks 10 approach each other, the silicone blocks can fit tightly with the automotive mold. To prevent the car mold from detaching during cutting, the robotic arm 23 is activated after the car mold is secured, driving the cutter 32 to cut the car mold. It's worth noting that during the cutting process, the cutter 32 generates heat, which can cause thermal stress deformation in both the car mold and the cutter 32. Therefore, when the cutter 32 starts working, the air pump 27 is simultaneously activated. The main function of the air pump 27 is to draw air into the interior and allow it to enter the heat exchanger through the connecting pipe 26. In the heat exchanger 25, the heat in the compressed air is removed by hot water or other media and transferred to the filter 29 through the expansion valve. Note that the compressed cold air is filtered in the filter 29. Its main purpose is to remove solid particles and water from the compressed cold air to prevent these impurities from damaging the cutter 32 or the automotive mold. Finally, the compressed cold air will be discharged from the four sets of jet nozzles 31 near the cutter 32 to locally cool the outer edge of the cutter 32, remove the heat generated by the cutter 32 during the cutting process, and prevent thermal stress deformation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
