Description

Technical Field

[0001] The invention relates to the technical field of plastic product production, in particular to an injection molding product grabbing device for injection molding. Background Art

[0002] At present, the injection molding machine is a common plastic processing equipment, which is mainly composed of injection device, mold clamping device, hydraulic system, electrical control system, etc. It heats and melts the plastic raw material, and then quickly injects it into the cavity of the closed mold at high pressure, and then cools and solidifies to obtain various plastic products. It is widely used in the manufacture of plastic parts and products of various shapes and sizes, such as plastic containers (such as plastic bottles, plastic barrels, etc.), plastic toys, plastic household items (such as plastic chairs, plastic hangers, etc.), plastic shells of electronic appliances, and many other fields.

[0003] After the injection molding product is cooled, the demoulding mechanism or ejection mechanism set in the mold will separate the product from the mold. The mechanical claw will clamp and transport the product only after the product is separated. After the product is separated from the mold, due to the lack of support from the mold and the inability of the mechanical claw to clamp the product in time, the product will fall directly downward and be damaged. In addition, due to the certain viscosity between the product and the mold, it is impossible to ensure that all positions of the product move at the same time during demoulding. Once the product is separated from the mold, it will tilt downward under the action of its own gravity, which may easily cause some products to tilt downward or diagonally downward. If the product is hung on the injection molding machine at an angle, the clamping position of the clamping device when clamping the product will be incorrect. Some products are relatively fragile, and incorrect clamping position may easily damage the product. Therefore, it is necessary to design a gripping device for injection molding products that can prevent product tilting. Summary of the invention

[0004] The object of the present invention is to provide an injection molded product gripping device for injection molding to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an injection molding product grabbing device for injection molding, comprising an injection molding machine, one side of the injection molding machine is provided with a conveyor belt assembly for conveying the injection molding product, a fixed mold is installed on the injection molding machine, and a three-axis linear module is installed on the top of one side of the fixed mold, characterized in that: a bottom plate is installed on one side of the three-axis linear module, the bottom plate is arranged in a concave shape, a limiting plate is fixedly installed on one side of the bottom plate, the limiting plate is arranged in a concave shape, the concave groove of the limiting plate coincides with the concave groove of the bottom plate, a clamping assembly for preliminarily clamping the demoulding product is installed on the bottom plate, both sides of the clamping assembly are provided with adjustment assemblies for pushing adjacent clamping assemblies to adjust the clamping force, a moving mold is installed on the injection molding machine, both sides of the bottom of the moving mold are provided with support assemblies for stably supporting the demoulding product, and both sides of the limiting plate are provided with first sliding grooves that penetrate through the limiting plate; The clamping assembly includes two sliding blocks slidingly arranged inside the first sliding grooves, extrusion sleeves inserted through the sides of the two sliding blocks, pushing columns inserted at one end of the two extrusion sleeves, and a first clamping plate fixedly installed at one end of the two pushing columns away from the extrusion sleeves, and a first rubber pad is fixedly installed on one side of the two first clamping plates for clamping, and push springs are sleeved on the two push columns, and the two ends of each push spring are respectively abutted against the adjacent extrusion sleeve and the first clamping plate.

[0006] Through the above technical solution, the pushing column can slide inside the extrusion sleeve. When one end of the extrusion sleeve is pushed from the outside, the pushing spring will be compressed, thereby pushing the first clamping plate. The pushing column will control the moving direction of the first clamping plate. As the pushing force applied to the extrusion sleeve becomes greater and greater, the two first rubber pads can clamp the demolding product with greater and greater force to prevent the clamping from loosening.

[0008] Through the above technical solution, the first connecting plate is connected to the pushing plate, so when the pushing plate moves left and right, it will move with the first connecting plate, so that the first connecting plate moves with the sliding block, allowing the entire extrusion sleeve to move, so that the first rubber pad can move together with the demolding product.

[0009] Preferably, the adjustment assembly includes an adjustment plate arranged on one side of the limit plate and having a second sliding groove, an adjustment column with one end passing through the second sliding groove, the side surface of the adjustment column is symmetrically connected to the limit column up and down, the limit column slides inside the second sliding groove, one end of the limit column abuts against the inner wall of the second sliding groove, and one end of the adjustment column is fixedly installed with one end of the extrusion sleeve.

[0010] With the above technical solution, one end of the limiting column passes through the adjusting column, and the two cooperate to form a cross-fixed manner to slide inside the second sliding groove, so that the adjusting column cannot escape from the second sliding groove, and when the adjusting plate moves away from or close to the limiting plate, the limiting column will drive the adjusting column to move, so that the adjusting column will pull or push the extrusion sleeve, so that the entire extrusion sleeve, the pushing column, the first clamping plate, the first rubber pad and the pushing spring move together, so that the two first rubber pads can be moved away from each other, which is convenient for clamping demolding products of different sizes, and the two first rubber pads can be brought closer to each other, so that the clamping force of the demolding product is continuously increased, thereby avoiding clamping the product forcefully during the demolding stage, resulting in the product being unable to be demolded normally.

[0011] Preferably, a first support plate is rotatably mounted on one end of the two adjustment plates away from the limiting plate, and one side of the two first support plates away from the adjustment plate are fixedly mounted to the limiting plate, and a second support plate is rotatably mounted on the other end of the two adjustment plates, and a third support plate is rotatably mounted on one end of the two second support plates away from the adjacent adjustment plates, and the two third support plates are arranged at the same inclination angle as the adjacent second support plates.

[0012] Through the above technical solution, when the third support plate moves downward and is at the same level as the adjacent second support plate, the second support plate will be pushed by the movement of the third support plate, so that the second support plate will push the adjustment plate, allowing the adjustment plate to rotate with the axis hinged to the first support plate as the center, and the movement of the adjustment plate will move with the limit column and the adjustment column, thereby realizing pre-clamping of demoulding products of different sizes to prevent them from tilting, and gradually increasing the clamping force as the adjustment column moves.

[0013] Preferably, a first cylinder is fixedly installed on one side of the limiting plate, a second connecting plate is fixedly installed on the pushing end of the first cylinder, a third connecting plate arranged in an inverted triangle is fixedly installed on the bottom of the second connecting plate, a rotating groove is provided on the side of the third connecting plate that is in contact with the limiting plate, one end of the two third support plates extends into the inside of the rotating groove, and is rotatably matched with the third connecting plate through a rotating shaft, a third sliding groove is provided on the side of the limiting plate that is in contact with the first cylinder, a moving block is slidably installed inside the third sliding groove, and one side of the moving block is fixedly installed to the third connecting plate.

[0014] Through the above technical solution, after the pushing part of the first cylinder is pushed out, the third connecting plate will move downward along the third sliding groove, so that the third connecting plate can push the two third support plates, so that the two third support plates can complete the synchronous downward movement, and the synchronous downward movement can drive the adjacent second support plates to move left and right.

[0015] Preferably, the upper and lower sides of the two second support plates are slidably provided with a first limiting plate fixedly installed with the limiting plate, and one side of the two third support plates is slidably matched with a second limiting plate fixedly installed with the limiting plate, the first limiting plate is set in an "L" shape, the second limiting plate is set in an arc shape, and the second limiting plate is provided with a limiting opening adapted to the third support plate.

[0016] Through the above technical solution, the first limiting plate and the second limiting plate can limit the movement range of the second supporting plate and the third supporting plate, and also enhance their stability.

[0017] Preferably, two rotating openings are opened on one side of the limit plate, and the supporting assembly includes a first driving plate rotatably installed inside the rotating opening, a second clamping plate fixedly installed in the middle of one side of the first driving plate, a second rubber pad fixedly installed on one side of the second clamping plate, and a supporting plate fixedly installed at the bottom of the second clamping plate, the second driving plate is rotatably installed on one end of the first driving plate, and the driving rod is rotatably installed on one end of the second driving plate.

[0018] Through the above technical solution, pulling the driving rod will cause one end of the second driving plate to be pulled and moved, so that the first driving plate hinged thereto will rotate with the axis installed inside the rotating mouth as the center of the circle. The rotation of the first driving plate will drive the second clamping plate to move in an arc, so that the supporting plate moves to the bottom of the demolding product to drag the product, and the second rubber pad will also fit and clamp the product to keep the product stable during the transfer process.

[0019] Preferably, a second cylinder is fixedly installed on one side of the base plate, and a fourth connecting plate is fixedly installed on the pushing end of the second cylinder, and the fourth connecting plate is arranged in an "L" shape. The bottom ends of the two driving rods are fixedly installed on the fourth connecting plate, and the top ends of the two driving rods are provided with a third limiting plate fixedly installed on the limit plate, and the bottom sides of the two third limiting plates are provided with movable grooves adapted to the driving rods.

[0020] Through the above technical solution, the second cylinder moves the fourth connecting plate, which in turn moves the fourth connecting plate with the driving rod. Through the above steps, the second clamping plate and the second rubber pad finally complete the stable clamping of the product.

[0021] Compared with the prior art, the invention has the following advantages: 1. By setting the clamping component and the adjusting component, when the injection molded product is demoulded, the clamping component will pre-clamp the product under the drive of the adjusting component. After the product is pre-clamped, it will not be tilted when hanging on the injection molding machine when demoulding, avoiding the damage of the product caused by the incorrect position of the clamping device; 2. By setting up a supporting component, after the clamping component clamps and demoulds the product, the supporting component will not only clamp the product from the bottom of the product, but also support the bottom of the product, so that the product can remain stable during transportation and prevent the product from falling; 3. By setting the clamping component, the adjustment component and the supporting component, after the clamping component pre-clamps the product, the adjustment component and the supporting component cooperate to allow the clamping component to clamp and move the product. During the movement of the clamping component, it will be continuously squeezed by the adjustment component to increase the clamping force and clamp the product. This can avoid clamping the product in the pre-clamping stage, which will cause the product to fail to demold normally. BRIEF DESCRIPTION OF THE DRAWINGS

The first rubber pads 405 are fixedly installed on the one side of the two first clamping plates 404 used for clamping. Push springs 406 are sleeved on the two pushing posts 403, and the two ends of each pushing spring 406 are respectively abutted against the adjacent extrusion sleeves 402 and the first clamping plates 404. A limiting ring larger than the diameter of the pushing post 403 is fixed on one end of the pushing post 403 located inside the extrusion sleeve 402 to prevent the pushing post 403 from sliding out of the extrusion sleeve 402. The pushing column 403 can slide inside the extrusion sleeve 402. When one end of the extrusion sleeve 402 is pushed by the outside, the pushing column 403 will be pushed. Then the first clamping plate 404 will stick to the side of the product due to the push of the pushing column 403. The extrusion sleeve 402 continues to be pushed, and the pushing column 403 will retract into the inside of the extrusion sleeve 402, so that the extrusion sleeve 402 cooperates with the first clamping plate 404 to compress the pushing spring 406, thereby pushing the first clamping plate 404. The pushing column 403 will control the moving direction of the first clamping plate 404. In this way, as the extrusion sleeve 402 is pushed by more and more force, the two first rubber pads 405 can clamp the demoulding product with greater and greater force to prevent the clamping from loosening.

[0026] A pushing opening is provided at the bottom of the limiting plate 8, and a pushing plate 9 is slidingly arranged inside the pushing opening. The pushing plate 9 is concavely arranged, and a first connecting plate 10 is symmetrically fixedly installed on the upper end of the pushing plate 9. The upper ends of the two first connecting plates 10 are fixedly connected to the lower ends of the adjacent sliding blocks 401. The first connecting plate 10 is connected to the pushing plate 9, so that when the pushing plate 9 moves left and right, it will move with the first connecting plate 10, so that the first connecting plate 10 can move with the sliding block 401, so that the entire extrusion sleeve 402 can move, so that the first rubber pad 405 can clamp the demolding product and move together, and the product is clamped by the cooperation of the two first clamping plates 404 and the first rubber pad 405, and moves with the product to prevent the product from tilting during the demolding process.

[0027] The adjustment component includes an adjustment plate 501 which is arranged on one side of the limiting plate 8 and has a second sliding groove, an adjustment column 502 with one end passing through the second sliding groove, and the side of the adjustment column 502 is symmetrically connected to the limiting column 503 up and down. The limiting column 503 slides inside the second sliding groove, and one end of the limiting column 503 abuts against the inner wall of the second sliding groove. One end of the adjustment column 502 is fixedly installed with one end of the extrusion sleeve 402, and one end of the limiting column 503 passes through the adjustment column 502. The two cooperate to form a cross-fixed manner to slide inside the second sliding groove, so that the adjustment column 502 cannot be separated from the second sliding groove. When the adjustment plate 501 moves away from or close to the limiting plate 8, the adjustment plate 501 will pass through the limiting column 50 3 drives the adjustment column 502 to move, so that the adjustment column 502 pulls or pushes the extrusion sleeve 402, so that the entire extrusion sleeve 402, the pushing column 403, the first clamping plate 404, the first rubber pad 405 and the pushing spring 406 move together, so that the two first rubber pads 405 can be moved away from each other, which is convenient for clamping demoulding products of different sizes, and the two first rubber pads 405 can be brought closer to each other. When the two first rubber pads 405 are close to each other, as the distance between the two is getting closer and closer, the clamping force applied to the demoulding product will be greater and greater, so that the clamping of the demoulding product is more stable, so that it can be avoided that the product is clamped hard during the demoulding stage, resulting in the product being unable to be demoulded normally.

[0028] The first support plate 11 is rotatably installed on one end of the two adjustment plates 501 away from the limiting plate 8, and the two first support plates 11 are fixedly installed on one side away from the adjusting plate 501. The second support plate 12 is rotatably installed on the other end of the two adjustment plates 501. The third support plates 13 are rotatably installed on one end of the two second support plates 12 away from the adjacent adjusting plates 501. The two third support plates 13 are arranged at the same inclination angle as the adjacent second support plates 12. When the third support plate 13 moves downward and the adjacent second support plates 12 are at the same level, the second support plate 12 will be pushed by the movement of the third support plate 13. In this way, the second support plate 12 will push the adjusting plate 501 to rotate away from the limiting plate 8, so that the adjusting plate 501 rotates with the axis hinged to the first support plate 11 as the center, and the movement of the adjusting plate 501 will move the limiting column 503 and the adjusting column 502.

[0029] A first cylinder 14 is fixedly installed on one side of the limiting plate 8, a second connecting plate 15 is fixedly installed on the pushing end of the first cylinder 14, a third connecting plate 16 arranged in an inverted triangle is fixedly installed on the bottom of the second connecting plate 15, a rotating groove is provided on the side where the third connecting plate 16 is in contact with the limiting plate 8, one end of each of the two third support plates 13 extends into the inside of the rotating groove, and is rotatably matched with the third connecting plate 16 through a rotating shaft, a third sliding groove is provided on the side where the limiting plate 8 is in contact with the first cylinder 14, a moving block is slidably installed inside the third sliding groove, one side of the moving block is fixedly installed with the third connecting plate 16, after the pushing portion of the first cylinder 14 is pushed out, the third connecting plate 16 will move downward along the third sliding groove, so that the third connecting plate 16 can be To push the two third support plates 13, so that the two third support plates 13 can complete the synchronous downward movement. The synchronous downward movement can drive the adjacent second support plate 12 to move left and right, and the first cylinder 14 retracts the pushing part, so that the third support plate 13 will move up along the third sliding groove, and one end of the two third support plates 13 will be driven to move up, thereby pulling the second support plate 12 to move. In this way, under the movement of the second support plate 12, the ends of the two adjustment plates 501 hinged to the second support plate 12 will be close to the limit plate 8. At this time, the adjustment plate 501 is in an inclined state with one end contacting the first support plate 11 away from the limit plate 8 and the other end close to the limit plate 8. This allows the adjustment plate 501 to reset, and so on and so forth, so that continuous operation can be performed.

[0030] The upper and lower sides of the two second support plates 12 are both slidably provided with a first limiting plate 17 fixedly installed with the limiting plate 8, and one side of the two third support plates 13 is slidably matched with a second limiting plate 18 fixedly installed with the limiting plate 8. The first limiting plate 17 is set in an "L" shape, and the second limiting plate 18 is set in an arc shape. The second limiting plate 18 is provided with a limiting opening adapted to the third support plate 13. The first limiting plate 17 and the second limiting plate 18 can limit the movement range of the second support plate 12 and the third support plate 13, and at the same time can also enhance their stability.

[0031] Two rotating openings are provided on one side of the limiting plate 8, and the supporting assembly includes a first driving plate 601 rotatably installed inside the rotating opening, a second clamping plate 602 fixedly installed in the middle of one side of the first driving plate 601, a second rubber pad 603 fixedly installed on one side of the second clamping plate 602, and a supporting plate 604 fixedly installed at the bottom of the second clamping plate 602. A second driving plate 605 is rotatably installed on one end of the first driving plate 601, and a driving rod 606 is rotatably installed on one end of the second driving plate 605. Pulling the driving rod 606 will cause one end of the second driving plate 605 to be pulled and moved, so that the first driving plate 601 hinged thereto will rotate with the axis installed inside the rotating opening as the center of the circle, and the rotation of the first driving plate 601 will drive the second clamping plate 602 to move in an arc, so that the supporting plate 604 moves to the bottom of the demoulding product to drag the product, and the second rubber pad 603 will also fit and clamp the product to keep the product stable during the transfer process.

[0032] A second cylinder 19 is fixedly installed on one side of the base plate 7, and a fourth connecting plate 20 is fixedly installed on the pushing end of the second cylinder 19. The fourth connecting plate 20 is arranged in an "L" shape. The bottom ends of the two driving rods 606 are fixedly installed on the fourth connecting plate 20, and the top ends of the two driving rods 606 are provided with a third limiting plate 21 fixedly installed on the limit plate 8. The bottom sides of the two third limiting plates 21 are provided with movable grooves adapted to the driving rods 606. The second cylinder 19 allows the fourth connecting plate 20 to move, which will allow the fourth connecting plate 20 to move with the driving rod 606. Through the above steps, the second clamping plate 602 and the second rubber pad 603 can finally complete the stable clamping of the product.

[0033] Working principle: When the injection molding machine 1 is performing product injection molding, after the movable mold is separated from the fixed mold, the product will be attached to the movable mold. At this time, the three-axis linear module 3 will move the bottom plate 7 to one side of the movable mold, and let the limit plate 8 rest against the base of the movable mold, so that the position of the movable mold and the product is at the center of the limit plate 8 in the horizontal direction.

[0034] After the position of the limit plate 8 is moved, the first cylinder 14 is started. After the pushing part of the first cylinder 14 is pushed out, the third connecting plate 16 will move downward along the third sliding groove, so that the third connecting plate 16 can push the two third support plates 13, so that the two third support plates 13 can complete the synchronous downward movement. In the process of the third support plate 13 moving downward and being at the same level with the adjacent second support plate 12, the second support plate 12 will be pushed by the movement of the third support plate 13, so that the second support plate 12 will push the adjustment plate 501, so that the adjustment plate 501 rotates away from the limit plate 8 with the axis hinged to the first support plate 11 as the center of the circle; When the adjustment plate 501 moves away from the limiting plate 8, the limiting column 503 will drive the adjustment column 502 to move inside the second sliding groove, so that the adjustment column 502 will push the extrusion sleeve 402, and the entire extrusion sleeve 402, the pushing column 403, the first clamping plate 404, the first rubber pad 405 and the pushing spring 406 will move together on the sliding block 401, so that the two first rubber pads 405 can be moved away from each other.

[0035] Then, the second cylinder 19 is started to move the fourth connecting plate 20 forward and backward. The movement of the fourth connecting plate 20 pulls the push plate 9 forward and backward. The sliding block 401 cooperates with the first connecting plate 10 connected to the push plate 9 to move inside the first sliding groove. After the second cylinder 19 cooperates with the pushing plate 9 to push the two sliding blocks 401 to both sides of the dynamic injection molded product, the first cylinder 14 retracts the pushing part, so that the third support plate 13 will move up along the third sliding groove, and one end of the two third support plates 13 will be driven up, thereby pulling the second support plate 12 to move. In this way, under the movement of the second support plate 12, the ends of the two adjustment plates 501 hinged to the second support plate 12 will be close to the limit plate 8. At this time, the adjustment plate 501 is in an inclined state with one end contacting the first support plate 11 away from the limit plate 8 and the other end close to the limit plate 8.

[0036] Due to the inclination of the adjustment plate 501, the positions of the two adjustment columns 502 move closer to each other, so that the first clamping plate 404 pushes the first rubber pad 405 to initially clamp the product still on the movable mold. The clamping force is relatively small and will not prevent the product from detaching from the movable mold. It will only support the product during the process of detaching from the movable mold to prevent the product from tilting after detaching, resulting in the subsequent incorrect clamping position and damage to the product surface.

[0037] After the two first rubber pads 405 initially clamp the product, the injection molding machine 1 will automatically separate the product from the movable mold and push it out. During the pushing process, the second cylinder 19 will simultaneously retract the pushing part. The retraction of the second cylinder 19 will allow the fourth connecting plate 20 to move with the driving rod 606. The forward and backward movement of the driving rod 606 will cause one end of the second driving plate 605 to be pulled and moved, allowing the first driving plate 601 hinged thereto to rotate with the axis installed inside the rotating mouth as the center of the circle. The rotation of the first driving plate 601 will drive the second clamping plate 602 to move in an arc, so that the supporting plate 604 moves to the bottom of the demoulding product to drag the product, and the second rubber pad 603 will also fit and clamp the product, so that the product remains stable and not easy to fall during transportation.

[0038] When the pushing part of the second cylinder 19 retracts, the pushing plate 9 will also move backwards, and the first connecting plate 10 will drive the sliding block 401 to slide inside the first sliding groove. Since the adjusting plate 501 is inclined, when the sliding block 401 moves, the adjusting plate 501 cooperates with the limiting column 503 to limit the positions of the two adjusting columns 502, so that the extrusion sleeve 402 is pushed by the adjusting column 502. As the sliding block 401 moves backwards, the adjusting column 502 is pushed further, so that the pushing spring 406 pushes the first clamping plate 404, thereby continuously increasing the clamping force of the demoulding product, avoiding the first clamping plate 404 clamping the product forcefully during the demoulding stage, resulting in the product being unable to be demoulded normally, thereby realizing pre-clamping of demoulding products of different sizes to prevent them from tilting, and gradually increasing the clamping force as the adjusting column 502 moves.

[0039] After the product is clamped, fixed and supported, the three-axis linear module 3 will drive the bottom plate 7 to move above the conveyor belt assembly 2. At this time, the pushing parts of the first cylinder 14 and the second cylinder 19 are pushed out successively, which will allow the first clamping plate 404 to separate from both sides of the product with the first rubber pad 405, and the second clamping plate 602 to separate from the bottom of the product with the second rubber pad 603 and the supporting plate 604. The product that loses the clamping and bottoming support will automatically pass through the grooves of the bottom plate 7 and the pushing plate 9 and fall on the conveyor belt assembly 2 to complete the transportation. After the product falls on the conveyor belt assembly 2, the first cylinder 14 and the second cylinder 19 are reset to clamp the product next time.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
