Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a deburring device for a mould. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting and stamping. Moulds are precision tools with complex shapes. They bear the expansion force of the blanks and have high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. They generally include two parts: movable mould and fixed mould (or punch and die). In order to reduce the surface roughness of the mould and improve the processing accuracy, a deburring device is required to remove the burrs on the mould.

[0003] A Chinese patent with application number CN221065887U discloses an efficient deburring mold processing device, including a shell, a plurality of threaded rods are movably sleeved on the outer surface of the shell, a plurality of handles are fixedly connected to the outer surface of the threaded rods, a plurality of sliding rods are movably sleeved on the inner surface of the shell, and a sliding groove is provided on the side of the outer surface of the shell close to two of the sliding rods. A spring pushes a gasket to clamp molds with different contours, thereby expanding the use area of ​​the deburring mold processing device. When employees process the mold, the sparks will be blocked by the shell and will not splash everywhere, posing a safety hazard to production. At the same time, the shell can be raised or lowered so that the shell is at a height that the employees can adapt to, avoiding the situation where the employees have to bend over or tiptoe, reducing the labor intensity of the employees, improving the work efficiency of the employees, and improving the work experience of the employees.

[0004] In the process of removing burrs, the existing deburring device usually uses a grinder or a brush to remove burrs. The grinder is mainly used to process a flat surface, but the deburring effect is poor for molds with complex shapes. The brush can clean molds with relatively complex shapes, but the deburring efficiency is low. At the same time, when removing burrs on the mold, the existing deburring device needs to change the surface and the contact with the processing mechanism multiple times before the burrs on the mold can be completely cleaned, thereby affecting the deburring efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0030] As shown Figures 1 to 6 in the figure, a deburring device for a mold according to the present invention includes: a box body 101 for preventing the diffusion of metal dust generated during grinding, thereby affecting the environment, a support plate 102 fixedly installed in the box body 101, the support plate 102 being in a horizontal state, a box door hinged at the front and rear opening positions of the box body 101, an observation window and a handle fixedly installed on the box door, a deburring component 300 for removing burrs, a moving component 400 for moving the deburring component 300, a rotating component 500 for rotating the mold, and a clamping component 200 for clamping the mold. A guiding groove for guiding the moving component 400, a clamping groove for installing the clamping component 200, and a through groove for facilitating the movement of the rotating component 500 are provided on the support plate 102.

[0031] The deburring component 300 includes: a brush roller 103 for cleaning burrs on the mold, the brush roller 103 being a metal wire brush roller, an adjusting device 308 for adjusting the distance between the brush roller 103 and the mold, a mounting rod 305 for detachably installing the brush roller 103, a first transmission belt 307 for driving the mounting rod 305 to rotate, a tensioning rod 306 for tensioning the first transmission belt 307, and a connecting rod for driving the first transmission belt 307 to move.

[0032] A support block for supporting the tensioning rod 306 and the mounting rod 305, the tensioning rod 306 and the mounting rod 305 being rotatably installed on the support block, a guiding rod 302 for limiting the tensioning rod 306, the guiding rod 302 restricting the moving direction of the tensioning rod 306, a spring 303 for ensuring the tensioning effect of the tensioning rod 306, the spring 303 pushing the tensioning rod 306 and the first transmission belt 307 into close contact through the elastic force of the spring 303, the spring 303 being wound around the guiding rod 302, a first threaded rod 304 for driving the mounting rod 305 to move, the support block being respectively slidably installed on the guiding rod 302 and threadedly installed on the first threaded rod 304, the first threaded rod 304 being rotatably installed in a mounting frame 301, the mounting frame 301 being divided into an adjusting mounting frame and a guiding mounting frame, the guiding mounting frame being fixedly connected to the side of the adjusting mounting frame, the guiding rod 302 being fixedly installed in the guiding mounting frame, and an installation groove being provided on the inner wall of the adjusting mounting frame.

[0033] Existing deburring devices usually choose grinding discs and brushes. The larger grinding disc can clean burrs faster, but it is mainly used for grinding flat surfaces. The smaller grinding disc has a lower cleaning efficiency. The brush has a faster cleaning speed, but the cleaning effect of the brush on the burrs on the mold is poor, and it needs to be cleaned repeatedly. By setting up the deburring component, the distance between the central axis of the brush roller 103 and the mold can be adjusted, so that the deburring effect of the brush roller 103 on the mold is not affected by the thickness of the mold. The high-speed rotation of the wire brush roller can grind the same position on the mold multiple times, without the need for the moving component 400 to run repeatedly. During the movement of the wire brush roller, the wire fully grinds the surface to be processed on the mold and sweeps away the ground metal dust from the mold, while having a better deburring effect and higher deburring efficiency.

[0034] A negative pressure pump 104 is fixedly installed on the tension rod 306. A filter box 105 is fixedly installed on the negative pressure pump 104. A connecting ring is threadedly installed on the top of the filter box 105. A filter bag for filtering metal dust is fixedly installed at the bottom of the connecting ring. The negative pressure pump 104 inhales air from the opening at the bottom of the filter box 105, and the metal dust in the air is filtered by the filter bag, reducing the content of metal dust in the air inside the box body 101.

[0035] The process of deburring the mold is also a grinding process. The brush roller 103 will generate metal dust when deburring. Since the brush roller will sweep the ground metal dust from the mold, it will cause the metal dust to spread in the air, and the metal dust will seriously affect the working environment of the staff and endanger the health of the staff. By setting up the sealed box body 101 to block the diffusion of metal dust in the air, the negative pressure pump 104 moves with the moving component 400, inhaling the air in the box body 101 from the top of the filter box 105, and the metal dust in the air is filtered by the filter bag, facilitating the collection of metal dust and reducing the content of metal dust in the air inside the box body 101. When there is more metal dust in the filter bag, the connecting ring can be rotated and removed to collect the metal dust in the filter bag.

[0036] The adjusting device 308 includes: a transmission gear 3082 rotatably installed in the installation groove, and second gears 3081 symmetrically arranged on both sides of the transmission gear 3082. The second gears 3081 are meshed with the transmission gear 3082. The two second gears 3081 are respectively fixedly installed on the first threaded rod 304 and the adjusting rod 3083. By manually rotating the rotating block at one end of the adjusting rod 3083 to drive the adjusting rod 3083 to rotate, the adjusting rod 3083 drives the second gear 3081 to rotate, the second gear 3081 drives the transmission gear 3082 to rotate, the transmission gear 3082 drives the other second gear 3081 to rotate, and the second gear 3081 drives the first threaded rod 304 to rotate, adjusting the distance between the central axis of the brush roller 103 and the mold.

[0037] The moving component 400 includes: a moving block 404 slidably installed in the guiding groove, the moving block 404 drives the deburring component 300 to move, a third motor 402 as a power source, and a support frame for supporting the third motor 402. The support frame is fixedly installed at the bottom of the moving block 404, the third motor 402 is fixedly installed on the support frame, a connecting rod fixedly connected to the rotating shaft of the third motor 402, the connecting rod passes through the moving block 404, a gear set 401 for reducing the rotating speed of the rotating shaft of the third motor 402, the gear set 401 serves as a speed reduction device to reduce the motor speed, and a first straight rack 403 engaged with the gear set 401. The first straight rack 403 is fixedly installed at the bottom of the support plate 102, and the first straight rack 403 is parallel to the guiding groove.

[0038] The gear set 401 includes: a third gear 4011 fixedly installed on the rotating shaft of the third motor 402, the rotating shaft of the third motor 402 drives the third gear 4011 to rotate, a large gear 4012 engaged with the third gear 4011, the third gear 4011 drives the large gear 4012 to rotate, a small gear 4013 coaxial with the large gear 4012, the large gear 4012 and the small gear 4013 are fixedly installed on the rotating shaft, the rotating shaft is rotatably installed on the fixing plate, the fixing plate is fixedly installed on the support frame, the large gear 4012 drives the small gear 4013 to rotate through the rotating shaft, the small gear 4013 is engaged with the first straight rack 403, and when the small gear 4013 rotates, it moves on the first straight rack 403, so that the moving component 400 drives the deburring component 300 to move at a lower speed, avoiding the reduction of the deburring effect due to the relatively fast moving speed of the brush roller 103.

[0039] The power sources of the moving component 400 and the deburring component 300 are both the third motor 402. The rotating speed of the brush roller 103 in the deburring component 300 is relatively high, while the moving speed of the moving block 404 in the moving component 400 is relatively low. When the moving speed of the moving block 404 is relatively high, it will affect the deburring effect of the brush roller 103 on the mold; by setting the gear set 401 as a speed reduction device, the rotating speed of the small gear 4013 is much lower than the rotating speed of the rotating shaft of the third motor 402, and the small gear 4013 rotates on the first straight rack 403, so that the moving block 404 moves in the guiding groove at a lower speed.

[0040] The clamping assembly 200 includes: a second bidirectional threaded rod 209 rotatably installed in a clamping groove, a second motor 210 for driving the second bidirectional threaded rod 209 to rotate, the second bidirectional threaded rod 209 being fixedly connected to the rotating shaft of the second motor 210, two clamping brackets 201 for adjusting the clamping distance, the clamping brackets 201 being symmetrically threadedly installed on the second bidirectional threaded rod 209, a fixed cylinder 202 fixedly installed on the clamping brackets 201, a clamping frame 204 for clamping the mold at both ends, a first bidirectional threaded rod 205 rotatably installed in the clamping frame 204, a clamping plate 206 for clamping the mold up and down, the clamping plate 206 being threadedly installed on the first bidirectional threaded rod 205, two first gears 207 meshing with each other, one of the first gears 207 driving the first bidirectional threaded rod 205 to rotate, the first gear 207 being driven to rotate by the other first gear 207, a first motor 208 for driving the other first gear 207 to rotate, and a rotating rod 203 for driving the clamping frame 204 to rotate. The rotating rod 203 is rotatably installed in the fixed cylinder 202, and the clamping frame 204 is fixedly installed at one end where the two rotating rods 203 are close to each other. When the clamping plate 206 and the clamping frame 204 contact the surface of the mold, they squeeze to remove the burrs on the contact surface.

[0041] It should be added here that both the clamping frame 204 and the clamping plate 206 are made of high-hardness metal materials. When they are in close contact with the mold, they can squeeze to remove the burrs at the contact position on the mold, avoiding the situation where the brush roller 103 fails to completely clean the burrs on the mold.

[0042] The rotating assembly 500 includes: a fixed frame 503 fixedly installed at the bottom of the clamping frame 201. When the clamping frame 201 moves, it drives the fixed frame 503 to move synchronously. A slider 502 slidably installed in the fixed frame 503, where the slider 502 is respectively in the states of sliding out and sliding into the fixed frame 503. An arc surface is provided on one side of the slider 502 close to the guiding groove, and a pushing block 501 that pushes the slider 502 through the arc surface on the slider 502. The pushing block 501 is fixedly installed on the support frame. The moving assembly 400 drives the pushing block 501 to move. A fourth gear 507 rotatably installed at the center of the bottom of the support plate 102, a second straight rack 506 meshing with the fourth gear 507, and a fixed frame 505 that restricts the moving range of the second straight rack 506. The second straight rack 506 is respectively located at both ends of the fixed frame 505. When one second straight rack 506 moves on the fixed frame 505, the second straight rack 506 drives the fourth gear 507 to rotate, and the fourth gear 507 drives the other second straight rack 506 to move on the fixed frame 505. The moving directions of the two second straight racks 506 are opposite. An expansion link 504 that enables the second straight rack 506 and the slider 502 to move synchronously, a second transmission belt 511 that drives the rotating rod 203 to rotate, and a transmission rod 512 that drives the second transmission belt 511 to move. The second transmission belt 511 is movably installed on the rotating rod 203 and the transmission rod 512. A fifth gear 510 that drives the transmission rod 512 to rotate. The fifth gear 510 is fixedly installed on the transmission rod 512, and a third straight rack 509 that drives the fifth gear 510 to rotate.

[0043] When the deburring assembly 300, the rotating assembly 500, and the moving assembly 400 use a single power source respectively, complex circuits and control systems are required to ensure that the deburring assembly 300, the rotating assembly 500, and the moving assembly 400 do not interfere with each other during operation, which also increases the cost. The power sources of the deburring assembly 300, the rotating assembly 500, and the moving assembly 400 are all the third motor 402. During the process of the moving assembly 400 driving the deburring assembly 300 to move, when the brush roller 103 moves beyond the position of the mold, the pushing block 501 pushes the slider 502 in the sliding-out state to slide into the fixed frame 503. Through the expansion link 504, the second straight rack 506, and the fourth gear 507, the slider 502 on the other side slides out of the fixed frame 503. The third straight racks 509 on the connecting frame 508 and the other third straight rack 509 move in opposite directions, but can drive the two fifth gears 510 to rotate in the same direction. Then, through the transmission rod 512 and the second transmission belt 511, the rotating rod 203 is rotated to turn the mold over, reducing the use of power sources. When the mold is flipped, the deburring assembly 300 moves to a position aligned with the clamping frame 201 to avoid obstructing the flipping of the mold, without the need for a complex control system, reducing costs and having higher practicality.

[0044] It should be added here that the second transmission belt 511 is selected as a chain transmission belt to avoid the influence of the weight of the mold on the rotation process when rotating the mold.

[0045] The telescopic rod 504 is composed of an outer sleeve rod, an inner sleeve rod, and an inner rod. The outer sleeve rod is fixedly connected to the second straight rack 506. The inner rod is fixedly connected to the slider 502. The inner sleeve rod is slidably installed in the outer sleeve rod, and the inner rod is slidably installed in the inner sleeve rod. When the pushing block 501 pushes the slider 502 in the slid-out state, the slider 502 drives the second straight rack 506 to move on the fixed frame 505 through the telescopic rod 504. The second straight rack 506 drives the fourth gear 507 to rotate, and the fourth gear 507 drives another second straight rack 506 to move in the opposite direction on the fixed frame 505, driving another slider 502 to slide out through another telescopic rod 504. When the clamping frame 201 drives the fixed frame 503 to approach each other, the telescopic rod 504 contracts. When the clamping frame 201 drives the fixed frame 503 to move away from each other, the telescopic rod 504 extends.

[0046] One of the third straight racks 509 is fixedly installed on the slider 502, and the other third straight rack 509 is fixedly installed on the connecting frame 508. The connecting frame 508 is fixedly installed on another slider 502. The two third straight racks 509 are respectively located on the upper and lower sides of the two fifth gears 510, so that the moving directions of the two third straight racks 509 are opposite, and the rotating directions of the driven fifth gears 510 are the same.

[0047] During the process of installing the mold, open the door on one side of the box body 101, align the two ends of the mold with the two clamping frames 204, start the second motor 210, the rotating shaft of the second motor 210 drives the second bidirectional threaded rod 209 to rotate, so that the two clamping frames 201 approach each other. The clamping frame 201 drives the fixed frame 503 to move, and the telescopic rod 504 contracts. When the clamping frame 204 touches the two ends of the mold, the second motor 210 is turned off. Start the first motor 208, the rotating shaft of the first motor 208 drives the first bidirectional threaded rod 205 to rotate, and the two clamping plates 206 on the first bidirectional threaded rod 205 approach each other to fixedly clamp the mold, and at the same time squeeze and remove the burrs at the contact positions of the clamping plates 206 and the clamping frames 204 on the mold.

[0048] Before deburring, open the box door on the other side of the box body 101, rotate the rotating block at one end of the adjusting rod 3083, the rotating block drives the adjusting rod 3083 to rotate, the adjusting rod 3083 drives the second gear 3081 acting as the driving gear to rotate, the second gear 3081 acting as the driving gear drives the transmission gear 3082 to rotate, the transmission gear 3082 drives the second gear 3081 acting as the driven gear to rotate, the second gear 3081 acting as the driven gear drives the first threaded rod 304 to rotate, so that the support block on the first threaded rod 304 moves in the adjusting mounting frame, driving the mounting rod 305 closer to the mold, enabling the wire brush roller on the mold to remove the burrs on the complex-shaped surface of the mold. At the same time, the first transmission belt 307 pulls the tensioning rod 306, and the tensioning rod 306 drives the support block at the bottom to move towards one end close to the adjusting mounting frame in the guiding mounting frame, compressing the spring 303, and the elastic force of the spring 303 pushes the support block to drive the tensioning rod 306 to tension the first transmission belt 307.

[0049] During the deburring process, start the third motor 402. The rotating shaft of the third motor 402 drives the connecting rod and the third gear 4011 to rotate. The connecting rod drives the tensioning rod 306 and the mounting rod 305 to rotate at high speed through the first transmission belt 307. The mounting rod 305 drives the brush roller 103 to rotate. The wires on the brush roller 103 polish and deburr the mold. The polished metal dust is sucked into the filter box 105 by the negative pressure pump 104 inside the box body 101. The filter bag in the filter box 105 filters out the metal dust, reducing the content of metal dust in the air inside the box body 101. The third gear 4011 drives the large gear 4012 to rotate, the large gear 4012 drives the rotating shaft to rotate, the rotating shaft drives the small gear 4013 to rotate, so that the rotation speed of the small gear 4013 is relatively low. The small gear 4013 meshes with the first straight rack 403 and moves on the first straight rack 403. The small gear 4013 drives the rotating shaft and the fixed plate to move, the fixed plate drives the support frame to move, and the support frame drives the moving block 404 to move in the guiding groove, moving the brush roller 103 at a relatively low speed to fully clean the burrs on the surface to be processed of the mold. At the same time, during the rotation of the brush roller 103, the parts on the top, bottom, and both ends of the surface of the mold are polished and deburred. The mold is flipped through the rotating assembly 500. The rotating shaft of the third motor 402 rotates in the reverse direction, the moving block 404 moves in the reverse direction in the guiding groove, and the brush roller 103 rotates in the reverse direction to remove the burrs on the other surface of the mold, and at the same time remove the burrs on the surfaces that have not been cleaned on the top, bottom, and both ends of the surface of the mold.

[0050] During the process of rotating the mold, when the brush roller 103 moves beyond the position of the mold, the pushing block 501 on the support frame pushes the slider 502 in the sliding-out state. When the slider 502 slides into the fixed frame 503, it drives the third straight rack 509 and the telescopic rod 504 to move. The telescopic rod 504 drives the second straight rack 506 to move on the fixed frame 505. The second straight rack 506 drives the fourth gear 507 to rotate. The fourth gear 507 drives another second straight rack 506 to move in the opposite direction on the fixed frame 505. The other second straight rack 506 drives the slider 502 to slide out of the fixed frame 503 through the telescopic rod 504. The connecting frame 508 drives the third straight rack 509 to move. The third straight rack 509 drives the fifth gear 510 to rotate. The fifth gear 510 drives the transmission rod 512 to rotate. The transmission rod 512 drives the second transmission belt 511 to move. The second transmission belt 511 drives the rotating rod 203 to rotate. The rotating rod 203 drives the clamping frame 204 to rotate, turning the mold over so that the other surface of the mold moves to the processing position.
