Description

Technical Field

[0001] This utility model relates to the field of injection molding processing technology, specifically to a product removal device. Background Technology

[0002] Injection molded parts are plastic products of various shapes made using plastic molds. However, injection molded parts that are ejected from the mold usually retain sprues from the plastic liquid that flowed in during injection. Therefore, after demolding, the sprues are usually removed from the injection molded part to obtain the injection molded part for later product manufacturing.

[0003] Existing injection molding part clamping devices, such as the utility model patent document with authorization announcement number "CN221793669U" and patent name "A clamp for removing sprues from injection molded parts", disclose an injection molding part clamping device, including a mounting plate, a support plate, and a clamping plate. The support plate is fixedly mounted on the side of the mounting plate, and the clamping plate is fixedly mounted on the side of the support plate. A suction cup is mounted on the clamping plate for sucking up the injection molded part from the mold. A crossbeam is provided on the clamping plate, and a pneumatic gripper is mounted on the crossbeam for clamping the sprue of the injection molded part.

[0004] In the aforementioned patent document, when removing the sprue from an injection-molded workpiece, the workpiece is directly adsorbed and fixed by a suction cup on a robotic arm, and then comes into contact with a shearing blade under the drive of a pneumatic device. When in contact, the suction cup is subjected to the impact force generated between the workpiece and the shearing blade. After long-term use, the suction cup is easily damaged, which can lead to the suction cup falling off and making it impossible to process the sprue of the injection-molded workpiece. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a product removal device. This device solves the technical problem mentioned in the background art: when removing sprue marks from injection molded workpieces, the workpieces are directly adsorbed and fixed by a suction cup on a robotic arm and come into contact with a shearing blade under the drive of a pneumatic device. During contact, the suction cup is subjected to the impact force generated between the workpiece and the shearing blade, which can easily damage the suction cup after long-term use, leading to the suction cup falling off and making it impossible to process the sprue marks of the injection molded workpieces.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A product removal device includes a support frame and a placement plate. The placement plate is slidably mounted on the support frame. A plurality of placement seats for placing injection-molded products are fixed on the placement plate. A plurality of clamping components for fixing the injection-molded products on the placement seats are provided on the placement plate. A sprue clamp for clamping the sprue is fixed on the placement plate. A plurality of pneumatic shears for cutting the joints of the injection-molded products are slidably mounted on the support frame. A drive component for moving the placement plate to one side of the pneumatic shears is provided on the support frame.

[0008] Working principle:

[0009] After the injection-molded product is formed by the injection molding machine, the operator moves the placement plate onto the injection molding machine using the drive assembly and places the injection-molded product on the placement seat. Then, the operator clamps and fixes the injection-molded product on the placement seat using the clamping assembly. After that, the operator fixes the sprue on the injection-molded product using the sprue clamp. Then, the operator moves the placement plate to the pneumatic shear, which cuts the joint of the injection-molded product. After the joint is cut, the operator releases the clamping assembly from the injection-molded product, allowing the injection-molded product to fall into the external injection-molded product collection box under its own weight. Then, the operator releases the sprue clamp, and the sprue on the injection-molded product falls into the external sprue collection box.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, it is equipped with a placement seat and a clamping assembly. The placement seat can be used to place the injection molded product on the placement plate, and the clamping assembly can be used to firmly and stably clamp the injection molded product on the placement seat, preventing the injection molded product from falling off the placement seat when it moves.

[0012] Secondly, it is equipped with a sprue clamp, which can hold the sprue of the injection molded product, preventing the sprue from falling into the collection box of the injection molded product after the product is cut.

[0013] Third, it is equipped with pneumatic shears, which can be used to cut the joints of injection molded products, ensuring that the cut size of the sprue is consistent and improving the quality of the injection molded products. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] like Figure 1 As shown, a product removal device includes a support frame 1 and a placement plate 2. The support frame 1 is provided with a drive assembly for moving the placement plate 2 to one side of a pneumatic scissors 5. The drive assembly includes a first screw 10, a first guide rod 11, a first motor 12, and a first slider 13. The first screw 10 is rotatably mounted on the support frame 1. The first guide rod 11 is fixed on the support frame 1 and is parallel to the first screw 10. The first motor 12 is fixed on the support frame 1 and its output end is fixedly connected to the first screw 10. The first slider 13 is screwed onto the first screw 10 and the first guide rod 11 is parallel to the first screw 10. The slider 13 is slidably connected to the first guide rod 11. The first screw 10 can be driven by the first motor 12. The first screw 10 can drive the first slider 13 to move on the first guide rod 11. A second cylinder 14 is fixed on the first slider 13 and the extension end of the second cylinder 14 is vertically downward. The placement plate 2 is fixed on the extension end of the second cylinder 14. The movement of the first slider 13 can drive the second cylinder 14 and the placement plate 2 on the extension end of the second cylinder 14 to move. The second cylinder 14 can drive the placement plate 2 to move vertically, thereby facilitating the movement of the placement plate 2 to the injection molding machine.

[0023] like Figure 2 and Figure 4 As shown, the placement plate 2 is slidably mounted on the support frame 1. Several placement seats 3 for placing injection molded products are fixed on the placement plate 2. Each of the placement seats 3 is provided with a placement groove 21 for placing injection molded products. The placement groove 21 on the placement seat 3 facilitates the placement of injection molded products in the injection molding machine.

[0024] like Figure 2 and Figure 3 and Figure 4As shown, the placement plate 2 is provided with several clamping components for fixing the injection molded product on the placement seat 3. The clamping components include a first cylinder 6, a clamping block 7, and a guide rod 8. The first cylinder 6 is fixed on the placement plate 2, and the clamping block 7 is fixed on the telescopic end of the first cylinder 6. The placement seat 3 is provided with a through hole 9. The guide rod 8 is slidably disposed in the through hole 9 and its end is fixedly connected to the clamping block 7. The first cylinder 6 can drive the clamping block 7 to move toward the injection molded product and clamp the injection molded product. The through hole 9 and the guide rod 8 can provide guidance when the clamping block 7 moves. The placement plate 2 is provided with a sprue clamp 4 for clamping the sprue. The sprue clamp 4 can clamp the sprue of the injection molded product.

[0025] like Figure 1 and Figure 5 As shown, a plurality of pneumatic shears 5 for cutting the joints of injection-molded products are slidably mounted on the support frame 1. Two bidirectional screws 15 are rotatably mounted on the support frame 1. Two second guide rods 16 parallel to the bidirectional screws 15 are fixedly mounted on the support frame 1. Two second sliders 17 are screwed onto the two threaded sections of the two bidirectional screws 15. Four second sliders 17 are slidably connected to the two second guide rods 16 respectively. The plurality of pneumatic shears 5 are fixedly mounted on the four second sliders 17 respectively. By rotating the bidirectional screws 15, the two second sliders 17 on the two threaded sections of the bidirectional screws 15 can move closer to each other, so that the pneumatic shears 5 on the two second sliders 17 can be reliably... Near the injection-molded product connection point, a pneumatic shear 5 is used to cut the connection point. A second motor 18 is fixed on the support frame 1, and the output end of the second motor 18 is fixedly connected to one of the bidirectional screws 15. Both bidirectional screws 15 are fixed with sprockets 19, and chains 20 are sleeved on the two sprockets 19. The second motor 18 can drive one of the bidirectional screws 15 and the sprocket 19 on that bidirectional screw to rotate. The rotation of the sprocket 19 can drive the chain 20, and the chain 20 can drive the sprocket 19 on the other bidirectional screw 15. Thus, the two bidirectional screws 15 are driven to rotate synchronously through the cooperation of the sprocket 19 and the chain 20.

[0026] like Figure 3 As shown, a push cylinder 22 for pushing up the injection molding waste is fixed on the placement plate 2. After the injection molding product is cut off at the joint, the injection molding product falls into the external injection molding product collection box by its own weight. Then, when the sprue clamp 4 is released, the push cylinder 22 can push the sprue of the injection molding product into the external sprue collection box.

[0027] Working principle:

[0028] After the injection molding of the product in the external injection molding machine is completed, the operator pneumatically activates the first motor 12, which drives the first screw 10. The first screw 10 drives the first slider 13 to move on the first guide rod 11. When the placement plate 2 moves to the injection molding machine, the operator drives the placement plate 2 toward the injection molding product on the injection molding machine through the second cylinder 14. Then, the ejector pin on the injection molding machine can push the injection molding product into the placement slot 21 on the placement seat 3. Subsequently, the operator starts the first cylinder 6, which drives the clamping block 7 to move toward the injection molding product and clamp the injection molding product on the placement seat 3.

[0029] The operator then moves the placement plate 2 to the pneumatic shears 5 on the support frame 1. The operator then starts the second motor 18, which drives one of the bidirectional screws 15 to rotate. Through the cooperation of the two sprockets 19 and the chain 20, the two bidirectional screws 15 rotate synchronously. Thus, the second sliders 17 on the two threaded sections of the two bidirectional screws 15 can drive the pneumatic shears 5 to move towards the connection between the injection molded product and the sprue. The pneumatic shears 5 can cut the connection between the injection molded product and the sprue. The operator then moves the placement plate 2 above the external injection molded product collection box. The first cylinder 6 and the clamping block 7 release the clamp on the injection molded product on the placement seat 3. The injection molded product falls into the injection molded product collection box under its own weight. Then, the placement plate 2 is moved above the external sprue collection box. Then, as the sprue clamp 4 is released, the push cylinder 22 can push the sprue of the injection molded product into the external sprue collection box.
