At the same time, the first motor drives the rotating rod to rotate along the mounting plate, so that the slider drives the first electric telescopic plate and the limiting structure to move simultaneously with the laser head. After moving to the appropriate position, the mold is cut by the laser head;

[0016] Step 2: When it is necessary to cut a hole of the same size and at a close distance in the vertical direction of the first hole after the mold is cut, the control valve is first used to allow the cold air inside the storage chamber to be transported downward by the cold air pipe, and the second electric telescopic plate is moved back and forth through the action of the moving structure, the first motor, the rotating rod and the slider, so that the first electric push rod drives the first connecting block and the second electric telescopic plate to move, and the first hole after cutting is cooled down, and then the laser head is moved to one side of the first hole after cutting, so that the limiting plate and the movable plate on the rear side of the laser head are located at the top of the inner wall of one side of the first hole, and the second motor inside the limiting plate on the rear side of the laser head is started to drive the threaded rod to rotate along the inner wall of the moving groove , so that the moving block moves downward along the inner wall of the moving groove, the push rod deflects and pushes the movable block to drive the third electric telescopic plate to move from the movable opening to the outside of the limiting plate, so as to adjust according to the size of the hole, and then the second connecting block, the limiting plate and the movable block are driven to move downward at the same time by the action of the second electric push rod, and the third electric telescopic plate is started to extend, so that the second telescopic rod is extended, so that the movable plate moves downward and fits the bottom inner wall of the first hole, so that the limiting plate and one side of the movable plate fit the inner wall of the first hole, and the first cooling block and the second cooling block are used to cool down at a limited time, and then the processing equipment is started to make the laser head cut one side of the first hole again;

[0017] Step 3: After the cutting is completed, the third electric telescopic plate drives the movable plate to move to the original position, and the second electric push rod drives the limiting plate and the movable plate to move to the original position. When it is necessary to cut a third hole with a close distance and the same size in the horizontal direction of the first hole, when the laser head moves to the horizontal side of the first hole, after adjusting to the appropriate position, the second electric telescopic plate on the right side of the laser head is opposite to the top of the left inner wall of the first hole, and then the second electric telescopic plate is started to move downward so that its bottom is in contact with the bottom inner wall of the first hole, and at the same time, one side of the second electric telescopic plate is in contact with the left inner wall of the first hole for limiting, and the temperature is reduced by the first cooling block, and then the laser head is allowed to cut;

[0019] Step 5: After the cutting is completed, the cutting quality of the notebook mold parts is comprehensively checked, burrs are removed and cleaned, the mold to be welded is thoroughly cleaned, and then welding is performed through the welding device.

[0020] The beneficial effects of the present invention are:

[0021] (1) The present invention can fit and limit the inner wall of one side of the adjacent hole by moving the second electric telescopic plate, the limiting plate and the movable plate. At the same time, the second electric push rod, the third electric telescopic plate and the movable plate can be adjusted according to holes of different sizes, so as to facilitate limiting holes of different sizes, thereby preventing the connection part between the two holes from being too small due to the distance between the two holes being too close, and the heat caused by the laser head during cutting causing the connection part to deform, thereby affecting the size and shape of the hole cut;

[0022] (2) The present invention uses a cold air pipe to cool the hole that needs to be cut with cold air inside the storage cavity. The first cooling block and the second cooling block function so that when the second electric telescopic plate, the limiting plate, the third electric telescopic plate and one side of the movable plate are in contact with the inner wall of the hole, the first cooling block and the second cooling block can cool the inner wall of the hole, thereby further improving the cutting effect and preventing the temperature from being too high during cutting, causing the connecting part of the two holes to deform and break, thereby affecting subsequent cutting.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] The present invention provides a laser cutting and welding device for mold processing, such as Figures 1 to 5 As shown, it includes a processing device 1, and a laser processing structure is arranged inside the processing device 1;

[0036] The laser processing structure includes a processing table 2, a mounting frame 3, a moving structure 4, a connecting seat 5, a laser head 6, a connecting plate 7, a first motor 8, a rotating rod 9, a mounting plate, a slider 10, a first electric telescopic plate 11 and a limiting structure. The mounting frame 3 is located inside the processing equipment 1. The moving structure 4 is arranged on both sides of the top of the mounting frame 3. A connecting seat 5 is arranged on one side of the moving structure 4. A laser head 6 is fixedly installed on one side of the connecting seat 5. A processing table 2 is arranged in the middle of the mounting frame 3 and located at the bottom of the laser head 6. A connecting plate 7 is arranged at the bottom of the moving structure 4 and located at the top of one side of the processing table 2. A first motor 8 is fixedly installed at the bottom of the connecting plate 7. The output end of the first motor 8 is transmission-connected with a rotating rod 9. One side of the rotating rod 9 is rotatably connected with a mounting plate. A slider 10 is threadedly connected to the middle of the rotating rod 9. The top of the slider 10 is slidably connected to the bottom of the connecting plate 7. A first electric telescopic plate 11 is fixedly installed on one side of the slider 10. A limiting structure is arranged on one side of the first electric telescopic plate 11.

[0037] The raw material of the mold is placed inside the processing equipment 1 and fixed on the processing table 2. At this time, the first electric telescopic plate 11 is in a retracted state, and the limiting structure is located at the rear side of the laser head 6. The connecting seat 5 drives the laser head 6 to move through the moving structure 4. After moving to a suitable position, the mold is cut by the laser head 6. When it is necessary to cut a hole of a close distance and the same size in the vertical direction of the first hole after the mold is cut, the limiting structure is moved to the bottom of the laser head 6 by extending the first electric telescopic plate 11, and the moving structure 4 moves so that the connecting seat 5 drives the laser head 6 to move to the cutting position, and the rotating rod is driven by the first motor 8 at the same time. 9 rotates along the mounting plate, so that the slider 10 drives the first electric telescopic plate 11 and the limiting structure to move simultaneously with the laser head 6. When the limiting structure moves to the top of the mold, the laser head 6 is moved to the position where one side of the first hole needs to be cut after cutting, so that the limiting structure can fit with the inner wall of the first hole, and the inner wall of one side of the first hole after cutting is limited. Then, the laser head 6 cuts one side of the first hole again through the processing equipment 1, so as to prevent the distance between the two holes from being too close during cutting, resulting in too few connecting parts between the two holes. The heat generated by the laser head 6 during cutting causes the connecting parts to be deformed, thereby affecting the size and shape of the hole cutting.

[0038] like Figures 3 to 5 As shown, the top of the mounting plate is fixedly mounted to the bottom of the connecting plate 7, one end of the first electric telescopic plate 11 is located at the bottom of the connecting seat 5, and it extends to one side of the laser head 6, the laser head 6 is located at the top of the processing table 2, and it is located in the middle of the defined structure.

[0039] The mounting plate facilitates the first motor 8 to drive the rotating rod 9 to remain stable when rotating, and facilitates the slider 10 to drive the limiting structure to move simultaneously with the laser head 6, so as to limit the laser head 6 when cutting holes. When the laser head 6 moves to the top of the first connecting block 13 and the second moving block 21, the limiting structure is driven to move to the rear side of the laser head 6 by contraction of the first electric telescopic plate 11, so that the laser head 6 continues to cut other shapes and parts of the mold, thereby improving the cutting effect of the laser head 6.

[0040] like Figures 4 to 6As shown, the limiting structure includes a first electric push rod 12, a first connecting block 13, a second connecting block 14, a second electric telescopic plate 15, a limiting plate 16, a movable plate 17 and a second electric push rod 18. The top of the first electric push rod 12 is fixedly installed with the bottom of the first electric telescopic plate 11, the first connecting blocks 13 are arranged on the front and rear sides of the laser head 6, the bottom of the first electric push rod 12 is fixedly installed with the first connecting block 13 on the rear side of the laser head 6, the second electric telescopic plate 15 is fixedly installed on the bottom of the first connecting block 13, the second connecting blocks 14 are arranged on the left and right sides of the laser head 6, the limiting plate 16 is fixedly installed on the bottom of the second connecting block 14, the movable plate 17 is arranged on the bottom of the limiting plate 16, two second electric push rods 18 are arranged in the middle of the second connecting block 14, and one end of the two second electric push rods 18 are fixedly installed on both sides of the first connecting block 13.

[0041] The first connecting block 13, the second connecting block 14, the second electric telescopic plate 15, the limiting plate 16, the movable plate 17 and the second electric push rod 18 are pushed to the top of the mold by the first electric push rod 12. When cutting the third hole, the second electric telescopic plate 15, the limiting plate 16 and the movable plate 17 can respectively fit with the inner walls of the first hole and the second hole to limit their inner walls, so as to improve the stability when cutting the third hole. The first connecting block 13 and the second electric telescopic plate 15 are driven to extend by the second electric push rod 18, so that they can be adjusted according to holes of different sizes, so as to improve the cutting effect, prevent the hole from deforming during cutting, and facilitate use.

[0042] like Figures 7 to 9 As shown, a moving groove is provided inside one end of the limiting plate 16 close to the second connecting block 14, and an adjusting structure is provided inside the moving groove;

[0043] The adjusting structure includes a second motor 19, a threaded rod 20, a moving block 21, a pushing rod 22, a movable block 23 and a third electric telescopic plate 24. The output end of the second motor 19 is drivingly connected to the threaded rod 20, and one end of the threaded rod 20 is threadedly connected to the moving block 21. Both sides of the moving block 21 are slidably connected to the inner wall of the moving groove, and both sides of the moving block 21 are hinged with pushing rods 22. One end of the pushing rod 22 is hinged with a movable block 23. The movable block 23 is movably connected to the inner wall of the moving groove, and the third electric telescopic plate 24 is fixedly installed on one side of the movable block 23. The top of the second motor 19 is fixedly installed to the inner wall of the top of the moving groove, and the bottom end of the threaded rod 20 is rotatably connected to the inner wall of the bottom of the moving groove. Both sides of the limiting plate 16 and the movable plate 17 are provided with movable openings, and the third electric telescopic plate 24 is located at the movable opening. The pushing rod 22, the movable block 23 and the third electric telescopic plate 24 are symmetrically arranged around the center of the moving groove.

[0044] When the size of the limiting plate 16 needs to be adjusted, the second motor 19 is started to drive the threaded rod 20 to rotate along the inner wall of the bottom of the movable groove, so that the movable block 21 moves downward from the threaded rod 20 along the inner wall of the movable groove, and the push rod 22 is deflected to push the movable block 23 to move along the inner wall of the movable groove, so that the movable block 23 drives the third electric telescopic plate 24 to move from the movable opening to the outside of the limiting plate 16 and the movable plate 17, thereby adjusting the length of the limiting plate 16 and the movable plate 17 to adapt to holes of different sizes and facilitate cutting holes of different sizes.

[0045] like Figures 7 to 9 As shown, a first fixed groove is provided on one side of the telescopic end of the third electric telescopic plate 24 and on the inner walls on both sides of the movable opening of the movable plate 17, a first telescopic rod 25 is fixedly installed inside the first fixed groove, the third electric telescopic plate 24 is connected to the movable plate 17 through the first telescopic rod 25, a second fixed groove is provided at the bottom of the threaded rod 20, a second telescopic rod 26 is fixedly installed inside the second fixed groove, and one end of the second telescopic rod 26 passes through the movable groove and is fixedly installed on the top of the movable plate 17.

[0046] When the third electric telescopic plate 24 moves from the movable opening to the outside of the limiting plate 16 and the movable plate 17, the first telescopic rod 25 is extended, and the third electric telescopic plate 24 is connected to the movable plate 17 through the first telescopic rod 25, thereby increasing the length of the movable plate 17 so that the length can be adjusted simultaneously with the limiting plate 16, and the limiting plate 16 is connected to the movable plate 17 through the second telescopic rod 26. When the third electric telescopic plate 24 is extended and moved downward, the movable plate 17 is driven to move downward by the first telescopic rod 25, so that the second telescopic rod 26 is extended, so that the movable plate 17 remains stable when moving downward. When the third electric telescopic plate 24 and the movable plate 17 are extended, they can fit with the bottom inner wall of the cut hole, so that the third electric telescopic plate 24, the limiting plate 16 and one side of the movable plate 17 can fit with the inner wall of one side of the cut hole, which is convenient for improving stability during cutting.

[0047] like Fig.10 As shown, a groove is provided at the bottom of the telescopic end of the second electric telescopic plate 15, a fixed plate 27 is fixedly installed on the inner wall of the groove, a storage cavity 28 is provided at the top of the fixed plate 27 and inside the telescopic end of the second electric telescopic plate 15, cold air is provided inside the storage cavity 28, a cold air pipe 29 is provided at the bottom of the fixed plate 27, and a control valve is provided at the top of the cold air pipe 29.

[0048] Through the control valve, the cold air inside the storage chamber 28 is transported downward by the cold air pipe 29, and the second electric telescopic plate 15 is moved back and forth through the action of the moving structure 4, the first motor 8, the rotating rod 9 and the slider 10. The cold air pipe 29 at the bottom of the second electric telescopic plate 15 is moved back and forth through the action of the first electric push rod 12 and the first connecting block 13, which cools the first hole after cutting, thereby facilitating the cutting of a hole of the same size and at a close distance in the vertical direction of the first hole after cutting, thereby preventing the temperature from being too high and the connection parts from being easily deformed when cutting close holes, thereby further improving the cutting stability.

[0049] like Figure 8 , Fig.10 As shown, the cold air pipes 29 are located at the bottom of the fixed plate 27 and are distributed in a linear array. The first cooling blocks 30 are fixedly installed on the outside of the second electric telescopic plate 15, the limiting plate 16 and the movable plate 17, and the second cooling blocks 31 are fixedly installed on the outside of the third electric telescopic plate 24.

[0050] The cooling air pipes 29 distributed in a linear array can improve the cooling effect. The first cooling block 30 allows the second electric telescopic plate 15, the limiting plate 16, and the movable plate 17 to fit the inner wall of the hole, thereby cooling the inner wall of the hole. The second cooling block 31 allows the third electric telescopic plate 24 to increase the length of the limiting plate 16 and the movable plate 17 while still cooling the inside of the hole, thereby preventing the size and accuracy from being affected, thereby further improving the accuracy of cutting other holes.

[0051] The present invention also provides a process for using the above-mentioned laser cutting and welding device for mold processing, comprising the following steps:

[0052] Step 1: Put the raw material of the mold into the processing equipment 1 and fix it on the processing table 2. The connecting seat 5 drives the laser head 6 to move through the moving structure 4. At the same time, the first motor 8 drives the rotating rod 9 to rotate along the mounting plate, so that the slider 10 drives the first electric telescopic plate 11 and the limiting structure to move simultaneously with the laser head 6. After moving to a suitable position, the mold is cut by the laser head 6;

[0053] Step 2: When it is necessary to cut a hole of the same size and at a short distance in the vertical direction of the first hole after the mold is cut, the control valve is first used to allow the cold air inside the storage chamber 28 to be transported downward by the cold air pipe 29, and the second electric telescopic plate 15 is moved back and forth through the action of the moving structure 4, the first motor 8, the rotating rod 9 and the slider 10, so that the first electric push rod 12 drives the first connecting block 13 and the second electric telescopic plate 15 to move, and the first hole after cutting is cooled, and then the laser head 6 is moved to one side of the first hole after cutting, so that the limiting plate 16 and the movable plate 17 on the rear side of the laser head 6 are located at the top of the inner wall of one side of the first hole, and the second motor 19 inside the limiting plate 16 on the rear side of the laser head 6 is started to drive the threaded rod 20 to rotate along the inner wall of the moving groove. The movable block 21 moves downward along the inner wall of the movable groove, the push rod 22 deflects and pushes the movable block 23 to drive the third electric telescopic plate 24 to move from the movable opening to the outside of the limiting plate 16, so as to adjust according to the size of the hole, and then the second connecting block 14, the limiting plate 16 and the movable block 23 are driven to move downward at the same time by the action of the second electric push rod 18, and the third electric telescopic plate 24 is started to extend, so that the second telescopic rod 26 is extended, so that the movable plate 17 moves downward and fits with the bottom inner wall of the first hole, so that the limiting plate 16 and one side of the movable plate 17 fit with the inner wall of the first hole, and the first cooling block 30 and the second cooling block 31 are used to cool down at a limited time, and then the processing equipment 1 is started to make the laser head 6 cut one side of the first hole again;

[0054] Step 3: After the cutting is completed, the third electric telescopic plate 24 drives the movable plate 17 to move to the original position, and the second electric push rod 18 drives the limiting plate 16 and the movable plate 17 to move to the original position. When it is necessary to cut a third hole with a close distance and the same size in the horizontal direction of the first hole, when the laser head 6 moves to the horizontal side of the first hole, after adjusting to a suitable position, the second electric telescopic plate 15 on the right side of the laser head 6 is opposite to the top of the left inner wall of the first hole, and then the second electric telescopic plate 15 is started to move downward so that its bottom is in contact with the bottom inner wall of the first hole, and at the same time, one side of the second electric telescopic plate 15 is in contact with the left inner wall of the first hole for limiting, and the temperature is reduced by the first cooling block 30, and then the laser head 6 is allowed to cut;

[0055] Step 4: When it is necessary to cut the left side of the second hole and the third hole in the vertical direction again, move the third electric telescopic plate 24 upward to its original position, move the laser head 6 to the position where cutting is required, so that the third electric telescopic plate 24 and the movable plate 17 are moved to the upper side of the second hole and opposite to its inner wall, start the second electric push rod 18 to move the first connecting block 13 and the second electric telescopic plate 15 on the right side to the left inner wall of the second hole, opposite to it, and start the third electric telescopic plate 24 and the second electric telescopic plate 15 at the same time, so that the second telescopic rod 26 is extended, the bottom of the movable block 23 is fitted with the inner wall of the bottom of the second hole, and one side of it is fitted with the upper inner wall of the second hole, the bottom of the second electric telescopic plate 15 is fitted with the inner wall of the bottom of the second hole, and is fitted with the inner wall on the left side, and after cooling by the first cooling block 30 and the second cooling block 31, the laser head 6 is allowed to cut;

[0056] Step 5: After the cutting is completed, the cutting quality of the notebook mold parts is comprehensively checked, burrs are removed and cleaned, the mold to be welded is thoroughly cleaned, and then welding is performed through the welding device.
