Description

[0001] The invention belongs to the technical field related to rotational molding molds, and in particular relates to an automatic disassembly and assembly device for rotational molding molds. Background Art

[0002] Roto-molding is a model made by hollow molding of thermoplastics. This molding method first adds plastic raw materials into the mold, and then the mold is continuously rotated and heated along two vertical axes. Under the action of gravity and heat energy, the plastic raw materials in the mold are gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, formed into the required shape, and then cooled and shaped into a finished product.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention sets a mold mechanism. When the second mold body and the adjusting frame are close to each other, the adjusting frame is pushed to move horizontally, and the limit hook moves horizontally with the adjusting frame. The arc-shaped plate end of the limit hook slides along the side surface of the adjusting roller, so that the limit hook rotates. When the adjusting frame is in close contact with the first mold body, the hook end of the limit hook rotates and is in close contact with the extended limit plate.

[0017] 3. The present invention sets a transmission support assembly and a limit adjustment mechanism, and the transmission roller moves and rolls along the corresponding adjustment transmission slide groove. As the transmission roller rolls along the downward slide groove and the upward slide groove, the first adjustment connecting rod is driven to reciprocate, and the first shaking support plate is synchronously rotated back and forth, so that the limit clamping assembly is synchronously rotated back and forth, thereby achieving the purpose of shaking out the formed component during the horizontal movement of the splitting, which is convenient for the subsequent cleaning of the inner wall of the mold.

[0018] 4. The present invention sets a cleaning component, and the eccentric transmission disk rotates, driving the travel wheel to roll along the inside of the adjustable transmission groove. During the rotation of the travel wheel, the transmission shaft is driven to rotate, and the cleaning roller is adjusted to rotate under the connection of the transmission belt. At the same time, the travel wheel moves up and down relatively, driving the cleaning roller to rotate. The cleaning roller moves up and down synchronously, thereby realizing reciprocating cleaning of the inner wall, increasing the cleaning effect, and avoiding the adhesion of residual materials that affect subsequent processing.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For specific embodiment 1, please refer to Figure 1-13 The present invention is an automatic disassembly and assembly device for a rotational molding mold, comprising a mold mechanism 1, a transmission support assembly 2, a symmetrically arranged limit adjustment mechanism 3 and a symmetrically arranged cleaning assembly 4. Specifically, the mold mechanism 1 comprises a first mold assembly 11, a second mold assembly 12 and a disassembly and assembly adjustment assembly 13. The disassembly and assembly adjustment assembly 13 is fixedly connected to the first mold assembly 11 by bolts, so that the disassembly and assembly adjustment assembly 13 can be flexibly installed according to needs. The disassembly and assembly adjustment assembly 13 comprises a plurality of rotatably arranged limit grabbing hooks 131, and the limit grabbing hooks 131 are rotated to realize installation or disassembly; the transmission support assembly 2 and the two limit adjustment mechanisms 3 are slidably matched, and the two limit adjustment mechanisms 3 are synchronously and unequally slid horizontally to realize mutual approach or separation. The transmission support assembly 2 comprises a symmetrically rotatably arranged transmission adjustment connecting rod 201, and the transmission adjustment connecting rod 201 is rotatably connected to the corresponding limit adjustment mechanism 3. The rotation of the transmission adjustment connecting rod 201 drives the two limit adjustment mechanisms 3 to synchronously slide horizontally to approach or separate from each other.

[0038] Furthermore, the limit adjustment mechanism 3 includes a limit clamping component 31 and a shake adjustment component 32. The shake adjustment component 32 is fixedly connected to the lower surface of the limit clamping component 31. The limit clamping component 31 includes symmetrically arranged L-shaped clamping plates 311. The L-shaped clamping plates 311 are close to each other to achieve clamping and fixing. The movement of the limit clamping component 31 drives the corresponding first mold component 11 or the second mold component 12 and the assembly and disassembly adjustment component 13 to move horizontally synchronously. The shake adjustment component 32 includes a first adjustment connecting rod 321 and a transmission roller 322 that are symmetrically rotated. The transmission roller 322 is in rolling cooperation with the transmission support component 2. The transmission roller 322 rolls to the corresponding When the mold mechanism 1 is in the position, the first adjusting link 321 rotates, thereby causing the limit clamping assembly 31 to swing synchronously (i.e., it rotates at a certain angle intermittently, which is convenient for shaking out the mold in the first mold assembly 11 or the second mold assembly 12 when the mold mechanism 1 is disassembled); the cleaning assembly 4 is fixedly mounted on the upper surface of the transmission support assembly 2, and the cleaning assembly 4 includes an eccentric transmission disk 401, a walking wheel 402 and a cleaning roller 403. The rotation of the eccentric transmission disk 401 drives the walking wheel 402 to rotate and move along a certain trajectory, thereby driving the cleaning roller 403 to move up and down and rotate at the same time. The rotation of the cleaning roller 403 can clean the inner wall of the first mold assembly 11 or the second mold assembly 12.

[0039] The operation process of this embodiment is: by driving two symmetrical L-shaped clamping plates 311 to approach each other, the first mold assembly 11 and the second mold assembly 12 are clamped and fixed respectively. During the rotation of the transmission adjustment link 201, the transmission adjustment link 201 drives the two limit adjustment mechanisms 3 to move horizontally and separate from each other synchronously, thereby driving the first mold assembly 11 and the second mold assembly 12 away from each other. When the openings of the first mold assembly 11 and the second mold assembly 12 are facing the cleaning roller 403, the cleaning roller 403 is controlled to be located inside the first mold assembly 11 and the second mold assembly 12, and the eccentric transmission disk 401 rotates, driving the cleaning roller 403 to move up and down and rotate at the same time to achieve continuous cleaning of the inner walls of the first mold assembly 11 and the second mold assembly 12.

A plurality of first support plates 134 are fixedly connected to the surface, and a limiting hook 131 is rotatably connected to a side surface of the corresponding first support plate 134. The limiting hook 131 is rotated to realize the disassembly or assembly operation. Adjustment grooves are provided on the opposite sides of the adjustment frame 132, and first return springs 135 corresponding to the limiting hooks 131 are fixed inside the adjustment grooves. One end of the first return spring 135 is fixedly connected to the corresponding limiting hook 131; the limiting hook 131 is a curved plate structure with a hook at one end and an arc-shaped plate at the other end. A plurality of second support plates 136 are fixedly connected to the opposite sides of the first mold body 111 by bolts, and an adjusting roller 137 is rotatably connected to one side of the second support plate 136. The adjusting roller 137 rolls with the arc-shaped outer surface of the corresponding limiting hook 131, and the limiting hook 131 drives the adjusting roller 137 to rotate during its movement.

[0041] Furthermore, the transmission support assembly 2 also includes a horizontal support plate 202, and a loading platform 203 is fixedly connected to the upper surface of the horizontal support plate 202. The mold mechanism 1 is placed on the loading platform 203 for easy alignment and splitting. An adjustment cavity is provided inside the horizontal support plate 202, and a guide slide 204 connected to the adjustment cavity is symmetrically provided on the upper surface of the horizontal support plate 202. A rectangular transmission disk 205 is rotatably connected to the bottom of the adjustment cavity, and one end of the transmission adjustment connecting rod 201 is rotatably connected to the upper surface of the rectangular transmission disk 205. During the rotation of the rectangular transmission disk 205, one end of the transmission adjustment connecting rod 201 moves synchronously with the rectangular transmission disk 205. A first driving motor is fixedly installed on the lower surface of the horizontal support plate 202, and the output shaft of the first driving motor is fixedly connected to the rectangular transmission disk 205. The first driving motor is used to drive the rectangular transmission disk 205 to rotate; the horizontal support plate 202 has symmetrical adjustment transmission slide grooves 206 on the two opposite inner side walls, and the adjustment transmission slide groove 206 consists of a plurality of horizontal slide grooves (such as Figure 8 (shown in section a) and several downward chutes (such as Figure 8 b) and several upward chutes (such as Figure 8 (as shown in section c) are connected in sequence.

[0042] Furthermore, the limit clamping assembly 31 also includes a clamping support frame 312, and L-shaped support plates 313 are slidably provided at both ends of the clamping support frame 312. The L-shaped clamping plate 311 is fixedly connected to the corresponding L-shaped support plate 313. The horizontal movement of the L-shaped support plate 313 drives the L-shaped clamping plate 311 to move horizontally synchronously. The inner surface of the L-shaped clamping plate 311 is provided with an anti-slip material. The anti-slip material increases the friction of the contact surface to prevent the clamped device from shifting during the movement and shaking process; an electric push rod 314 is fixedly installed on the side wall of the clamping support frame 312 away from the L-shaped clamping plate 311, and one end of the output shaft of the electric push rod 314 is fixedly connected to a clamping adjustment plate 315, and the electric push rod 314 is used to drive the clamping adjustment plate 315 to move horizontally The clamping transmission frame 316 is symmetrically and slidably arranged on the side surface of the clamping adjustment plate 315, and a first clamping link 317 is rotatably connected to one side of the clamping transmission frame 316, and one end of the first clamping link 317 is rotatably connected to one side of the clamping support frame 312. The clamping adjustment plate 315 moves horizontally to drive the first clamping link 317 to rotate, so that the clamping transmission frame 316 slides along the side surface of the clamping adjustment plate 315, and a second clamping link 318 is rotatably connected to the side of the clamping transmission frame 316 away from the first clamping link 317, and one end of the second clamping link 318 is rotatably connected to the corresponding L-shaped support plate 313. During the movement of the clamping transmission frame 316, the second clamping link 318 rotates to drive the L-shaped support plate 313 to move horizontally.

[0043] Furthermore, the shake adjustment component 32 also includes a plurality of support columns 323 fixedly connected to the lower surface of the clamping support frame 312, a first shake support plate 324 is fixedly connected between the support columns 323, and a telescopic column 325 is symmetrically fixedly connected to the lower surface of the first shake support plate 324 through a connecting piece (that is, a spherical hinge seat is connected between the top of the telescopic column 325 and the bottom of the first shake support plate 324 to meet the rotation requirement of the first shake support plate 324). When the first shake support plate 324 tilts, under the connection of the connecting piece, the connecting piece rotates so that the telescopic column 325 is compressed, and a second shake support plate 326 is fixedly connected between the two telescopic columns 325. The second shake support plate 326 is slidably set at the top of the adjustment cavity, and a second return spring 327 is symmetrically fixedly connected between the first shake support plate 324 and the second shake support plate 326. The second return spring 327 is sleeved on the outside of the corresponding telescopic column 325; the first adjusting link 321 is rotatably connected to a side of the second shaking support plate 326 through the rotating shaft, and the first adjusting link 321 is rotatably connected to the ear plate fixedly connected to the lower surface of the first shaking support plate 324. The connection point between the first adjusting link 321 and the first shaking support plate 324 is away from the telescopic column 325. When the first adjusting link 321 rotates, the first shaking support plate 324 tilts. A second adjusting link 328 is fixedly connected to the side surface of the rotating shaft, and the transmission roller 322 is rotatably connected to a side of the second adjusting link 328, and the transmission roller 322 rolls and fits inside the adjustment transmission slot 206. The first adjusting link 321 passes through the corresponding guide slot 204. When the limit adjustment mechanism 3 moves horizontally, the first adjusting link 321 slides along the corresponding guide slot 204.

[0044] The operation process of this embodiment is as follows: when the first mold assembly 11 and the second mold assembly 12 need to be spliced, the first mold assembly 11 and the second mold assembly 12 are controlled to be close to each other. When the second mold body 121 and the adjustment frame 132 are fitted to each other, the adjustment frame 132 is pushed to move horizontally with the horizontal movement of the second mold body 121, and the adjustment limit column 133 slides along the corresponding adjustment slot 112. In this process, the limit hook 131 moves horizontally synchronously with the adjustment frame 132, and the elastic recovery action of the first return spring 135 is performed. By using the strong elastic force of the first return spring 135 in the compressed state, the limit hook 131 is always tightly pressed against the adjusting roller 137, so that the arc plate end of the limit hook 131 always slides along the side surface of the adjusting roller 137, driving the adjusting roller 137 to rotate. At the same time, due to the setting of the arc plate, the limit hook 131 rotates. When the adjusting frame 132 is in close contact with the first mold body 111, the hook end of the limit hook 131 rotates and is in close contact with one side of the extended limit plate 122, thereby completing the splicing operation of the mold mechanism 1.

[0045] When it is necessary to split the mold mechanism 1, place it on the stage 203. The two limit clamping assemblies 31 in the initial state are respectively located on the two opposite sides of the mold mechanism 1, and the two L-shaped clamping plates 311 are respectively located on the other two opposite sides of the mold mechanism 1. The electric push rod 314 is used to push the clamping adjustment plate 315 to move horizontally. During this process, the first clamping link 317 rotates to push the corresponding clamping transmission frame 316 to slide horizontally along the side surface of the clamping adjustment plate 315, and the two clamping transmission frames 316 approach each other. At the same time, the movement of the clamping transmission frame 316 drives the second clamping link 318 to rotate. The second clamping link 318 is used to rotate and push the L-shaped support plate 313 to move horizontally, so that the two L-shaped clamping plates 311 approach each other until they are tightly attached to the two opposite sides of the first mold body 111 or the second mold body 121, thereby clamping and fixing them.

[0046] Start the first driving motor to drive the rectangular transmission disk 205 to rotate. The rectangular transmission disk 205 rotates and drives the two transmission adjustment links 201 to move synchronously, and causes the transmission adjustment link 201 to rotate. The transmission adjustment link 201 pushes the corresponding limit adjustment mechanism 3 to move horizontally, so that the limit adjustment mechanism 3 drives the first mold assembly 11 and the second mold assembly 12 to move synchronously in the opposite direction and away from each other. During this process, the limit hook 131 slides along the surface of the extended limit plate 122, and the limit hook 131 rotates in the opposite direction. The first return spring 135 is compressed, and the arc-shaped plate end of the limit hook 131 slides along the side surface of the adjusting roller 137, and the adjusting roller 137 rotates in the opposite direction until the first mold assembly 11 and the second mold assembly 12 are separated from each other, and then the first mold assembly 11 and the second mold assembly 12 move horizontally synchronously with the corresponding limit adjustment mechanism 3.

[0047] When the limit adjustment mechanism 3 moves horizontally, the transmission roller 322 moves and rolls along the corresponding adjustment transmission slot 206. When the transmission roller 322 rolls along the horizontal slot to the adjacent downward slot, the transmission roller 322 slides along the downward slot, driving the second adjustment link 328 to rotate a certain angle. The rotation shaft rotates a certain angle, driving the first adjustment link 321 to rotate. The first adjustment link 321 pushes one end of the first shaking support plate 324 to move upward, so that the first shaking support plate 324 rotates a certain angle, and the telescopic column 325 is compressed by the connecting piece. And the second return spring 327, when the first shaking support plate 324 rotates, it drives the limit clamping assembly 31 to rotate synchronously by a certain angle, and then drives the corresponding first mold assembly 11 or the second mold assembly 12 to rotate by a certain angle. When the transmission roller 322 continues to roll and moves to the inside of the upward slide groove, the transmission roller 322 rolls along the upward slide groove, driving the first adjusting link 321 to rotate in the opposite direction, and the first shaking support plate 324 rotates in the opposite direction by a certain angle, and the forming device inside the first mold assembly 11 or the second mold assembly 12 is shaken out through intermittent reciprocating rotation.

[0048] For specific embodiment 3, please refer to Figure 2-11 On the basis of the first and second specific embodiments, specifically, the cleaning component 4 also includes a cleaning support frame 404 symmetrically fixedly connected to the upper surface of the horizontal support plate 202, an eccentric transmission disk 401 is rotatably connected to one side of the cleaning support frame 404, an adjusting transmission groove 405 is opened on one side of the eccentric transmission disk 401, and the walking wheel 402 rolls with the side surface of the adjusting transmission groove 405. The rotation of the eccentric transmission disk 401 drives the walking wheel 402 to walk along the side surface of the adjusting transmission groove 405, so that the walking wheel 402 is always located at the lowest position of the adjusting transmission groove 405, and moves up and down with the rotation of the eccentric transmission disk 401. A second driving motor 406 is fixedly installed on one side of the cleaning support frame 404 away from the eccentric transmission disk 401, and the output shaft of the second driving motor 406 is fixedly connected to the eccentric position of the corresponding eccentric transmission disk 401, and the second driving motor 406 is used to drive the eccentric transmission disk 401 to rotate.

[0049] Furthermore, a transmission shaft 407 is fixedly connected between the two walking wheels 402. The rotation of the walking wheels 402 drives the transmission shaft 407 to rotate synchronously. Support blocks 408 are symmetrically sleeved on the sides of the transmission shaft 407. The upper surfaces of the support blocks 408 are fixedly connected with limited support columns 409. The support blocks 408 move up and down synchronously with the transmission shaft 407, thereby driving the limited support columns 409 to move up and down synchronously. The limited support columns 409 slide through the cleaning support frame 404. A third return spring 410 is fixedly connected between the cleaning support frame 404 and the support block 408 (the third return spring 410 is always in a compressed state to ensure that the walking wheels 402 are always tightly against the inner wall of the adjusting transmission groove 405). The third return spring 410 is sleeved on the outside of the limited support column 409; A first transmission wheel 411 is fixedly connected to the surface symmetrically, and the first transmission wheel 411 rotates synchronously with the transmission shaft 407. A support sleeve 412 sleeved on the outside of the transmission shaft 407 is fixedly connected to one side of the support block 408. An extended support plate is fixedly arranged on the side of the support sleeve 412. A linkage shaft is rotatably arranged between the two extended support plates. The cleaning roller 403 is fixedly arranged on the side of the linkage shaft. A second transmission wheel 413 corresponding to the first transmission wheel 411 is fixedly arranged on the side of the linkage shaft. The second transmission wheel 413 is connected to the corresponding first transmission wheel 411 through a transmission belt 414. In the initial state, the transmission shaft 407, the support block 408 and the cleaning roller 403 are located at the lowest position of the adjustment transmission groove 405. At this time, the position close to the cleaning support frame 404 belongs to the highest position of the adjustment transmission groove 405. Fig.12As shown, when the eccentric transmission disk 401 is controlled to rotate 180°, the walking wheel 402 gradually moves downward along the inner wall of the adjustment transmission groove 405 until the walking wheel 402 is located at the highest position of the eccentric transmission disk 401 in the initial state, so that the limit adjustment mechanism 3 can be horizontally moved to the two ends of the horizontal support plate 202, and the second transmission wheel 413 rotates to drive the cleaning roller 403 to rotate.

[0050] The operation process of this embodiment is as follows: when the two limit adjustment mechanisms 3 move horizontally to the two ends of the horizontal support plate 202 respectively, the second drive motor 406 is started to drive the eccentric transmission disk 401 to rotate, so that the walking wheel 402 moves along the side surface of the adjustment transmission groove 405, and the rotation of the walking wheel 402 drives the transmission shaft 407 to rotate synchronously, and the walking wheel 402 always rotates to the lowest point of the adjustment transmission groove 405. Due to the eccentric setting of the eccentric transmission disk 401, the lowest point of the eccentric transmission disk 401 moves up and down periodically during the rotation process. During this process, the walking wheel 402 moves downward relatively, driving the transmission shaft 407 to move downward synchronously, so that the support block 408 moves downward, and the limit support column 409 moves downward synchronously. The third reset spring 410 gradually reduces its compression amount under the action of elastic recovery. At the same time, under the connection action of the support sleeve 412, the cleaning roller 403 moves downward synchronously until the first mold assembly 11 The opening of the second mold assembly 12 is directly opposite to the corresponding cleaning roller 403; at this time, stop driving the second drive motor 406, and then drive the rectangular transmission disk 205 to rotate in the opposite direction, so that the first mold assembly 11 and the second mold assembly 12 are close to each other, until the cleaning roller 403 is located inside the first mold assembly 11 and the second mold assembly 12, and then start the second drive motor 406 to drive the eccentric transmission disk 401 to rotate reciprocatingly, so that the transmission shaft 407 rotates, and drives the first transmission wheel 411 to rotate, and drives the second transmission wheel 413 to rotate under the connection action of the transmission belt 414, thereby causing the cleaning roller 403 to rotate, and at the same time, the lowest point of the eccentric transmission disk 401 moves up and down periodically, so that the cleaning roller 403 and the support block 408 are driven by the walking wheel 402 to move up and down synchronously with the rotation of the eccentric transmission disk 401, so as to realize the reciprocating cleaning of the inner walls of the first mold assembly 11 and the second mold assembly 12.
