Description

Technical Field

[0001] This utility model belongs to the field of plastic part gate removal technology, specifically a plastic part gate removal tooling. Background Technology

[0002] After the production of plastic products is completed, there will be excess parts and gates on the surface of the plastic products. Plastic products containing excess parts cannot be used directly and need to be removed. Therefore, a tooling for removing gates from plastic parts is needed.

[0003] Existing plastic part gate removal fixtures include: shearing table, pressure cutting seat, telescopic rod, cutting mechanism, etc. After fixing the plastic part whose gate needs to be removed, the cutting blade is driven by the cylinder to cut off the gate of the plastic part, thereby meeting the needs of plastic part gate removal.

[0004] However, existing devices still have some problems. The fixed component structure inside the tooling is fixed, which makes it impossible to fix plastic parts of different sizes, thus reducing the scope of application of the tooling. Therefore, a tooling for removing the gate of plastic parts is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a tooling for removing the gate of plastic parts.

[0006] The technical solution adopted by this utility model to solve its technical problem is a tooling for removing gates from plastic parts, including: a worktable, the worktable having symmetrically formed first limiting grooves inside, a first limiting plate slidably connected inside the first limiting groove, a support rod fixedly connected to one side of the first limiting plate, and the support rod slidably connected inside the first limiting groove, threaded holes being formed on both the worktable and the support rod, a return spring fixedly connected to the inner wall of the first limiting groove, the other end of the return spring fixedly connected to one side of the first limiting plate, a fixing bolt threadedly connected inside the threaded hole, a clamping plate fixedly connected to one end of the support rod, a base plate fixedly connected to the bottom of the clamping plate, and two sets of second limiting grooves being formed inside both sets of clamping plates, with two sets of second limiting plates slidably connected inside one set of second limiting grooves. By screwing the fixing bolt into the threaded hole, the position of the support rod can be fixed, thereby fixing the plastic part.

[0007] Preferably, a reinforcing plate is fixedly connected between the two sets of second limiting plates. The reinforcing plate is slidably connected inside the two sets of clamping plates. A support frame is fixedly connected to the upper surface of the worktable. The reinforcing plate connects the two sets of clamping plates, thereby strengthening the external wrapping strength of the plastic part and improving the fixing strength of the plastic part.

[0008] Preferably, a first drive motor is fixedly connected to one side of the support frame, and a bidirectional threaded rod is fixedly connected to the output end of the first drive motor. A connecting block is threaded onto the bidirectional threaded rod, and the connecting block has an internal thread. When the first drive motor is started, the bidirectional threaded rod is driven to rotate. Since the thread on the bidirectional threaded rod matches the internal thread of the connecting block, the position of the connecting block can be adjusted.

[0009] Preferably, an electric telescopic rod is fixedly connected to one side of the connecting block, a dust cover is fixedly connected to the outer side of the telescopic end of the electric telescopic rod, and a second drive motor is fixedly connected to the telescopic end of the electric telescopic rod. During cutting, the dust cover can wrap the debris and reduce the range of debris diffusion.

[0010] Preferably, the output end of the second drive motor is provided with a cutting blade, a dust suction pipe is fixedly connected to the dust cover, the dust suction pipe passes through the support frame, and a dust collection box is fixedly connected to the upper surface of the workbench. By running the second drive motor, the cutting blade is driven to rotate, thereby removing excess gates from the plastic parts.

[0011] Preferably, the suction pipe is fixedly connected to the suction box, a fan is fixedly connected inside the suction box, an exhaust port is opened on one side of the suction box, a door is hinged to one side of the suction box, and a filter screen is fixedly connected inside the suction box. When the fan is running, the air and debris drawn in are separated by the filter screen. The debris remains inside the suction box, and the air is discharged outward through the exhaust port, thus collecting the debris.

[0012] The advantages of this utility model are: by pushing the two sets of clamping plates outward, the first limiting plate and the support rod move into the first limiting groove, thereby squeezing the return spring. Then, the plastic part that needs to have its gate removed is placed between the two sets of clamping plates. After releasing the clamping plates, without applying external force, the return spring can push the clamping plates to the surface of the plastic part, thereby cooperating with the fixing bolt. This allows for the fixing of plastic parts of different sizes, thus expanding the applicability of the tooling.

[0013] When the distance between the two sets of clamping plates changes, the two sets of second limiting plates are driven by the two sets of clamping plates and move within the two sets of second limiting grooves, thereby adjusting the exposed length of the reinforcing plate and connecting the two sets of clamping plates. This strengthens the external wrapping strength of the plastic part and improves the fixing strength of the plastic part, preventing damage to the plastic part due to movement during the gate cutting process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a tooling for removing the gate of a plastic part includes: a workbench 1, with a first limiting groove 2 symmetrically opened inside the workbench 1, a first limiting plate 3 slidably connected inside the first limiting groove 2, a support rod 4 fixedly connected to one side of the first limiting plate 3, and the support rod 4 slidably connected inside the first limiting groove 2, threaded holes 5 opened on both the workbench 1 and the support rod 4, a return spring 6 fixedly connected to the inner wall of the first limiting groove 2, the other end of the return spring 6 fixedly connected to one side of the first limiting plate 3, a fixing bolt 7 threadedly connected inside the threaded hole 5, a clamping plate 8 fixedly connected to one end of the support rod 4, a base plate 9 fixedly connected to the bottom of the clamping plate 8, a second limiting groove 10 opened inside both sets of clamping plates 8, two sets of second limiting plates 11 slidably connected inside one set of second limiting grooves 10, a reinforcing plate 12 fixedly connected between the two sets of second limiting plates 11, the reinforcing plate 12 slidably connected inside the two sets of clamping plates 8, and a support frame 13 fixedly connected to the upper surface of the workbench 1;

[0023] After the plastic product is manufactured, there will be excess parts and gates on the surface of the plastic product. Therefore, a plastic part gate removal tool is needed to remove the excess gates from the surface of the plastic product. In actual use, the two sets of clamping plates 8 are pushed outward, so that the first limiting plate 3 and the support rod 4 move into the first limiting groove 2, and at the same time, the return spring 6 is squeezed. Then, the plastic part to be degated is placed between the two sets of clamping plates 8. The clamping plates 8 are released, and the elastic force of the return spring 6 pushes the clamping plates 8 towards the surface of the plastic part, so that the clamping plates 8 are in contact with the surface of the plastic part, and the base plate 9 is located at the bottom of the plastic part. Then, the fixing bolts 7 are screwed into the threaded holes. Within 5 seconds, the plastic part can be fixed. The return spring 6 can push the clamping plate 8 to the surface of the plastic part without applying external force, so as to cooperate with the fixing bolt 7 and fix plastic parts of different sizes. When the distance between the two sets of clamping plates 8 increases or decreases, the two sets of second limiting plates 11 are driven by the two sets of clamping plates 8 respectively and move within the second limiting groove 10, adjusting the exposed length of the reinforcing plate 12 and connecting the two sets of clamping plates 8, thereby strengthening the external wrapping strength of the plastic part and improving the fixing strength of the plastic part, avoiding damage to the plastic part due to movement during the cutting of the plastic part gate.

[0024] Please see Figure 1-5As shown, a first drive motor 14 is fixedly connected to one side of the support frame 13. A bidirectional threaded rod 15 is fixedly connected to the output end of the first drive motor 14. A connecting block 16 is threaded onto the bidirectional threaded rod 15. The connecting block 16 has an internal thread. An electric telescopic rod 17 is fixedly connected to one side of the connecting block 16. A dust cover 18 is fixedly connected to the outer side of the telescopic end of the electric telescopic rod 17. A second drive motor 19 is fixedly connected to the telescopic end of the electric telescopic rod 17. A cutting blade 20 is provided at the output end of the second drive motor 19. A suction pipe 21 is fixedly connected to the dust cover 18. The suction pipe 21 passes through the support frame 13. A dust collection box 22 is fixedly connected to the upper surface of the workbench 1. The suction pipe 21 is fixedly connected to the dust collection box 22. A fan 23 is fixedly connected inside the dust collection box 22. An exhaust port is opened on one side of the dust collection box 22. A door is hinged on one side of the dust collection box 22. A filter screen 24 is fixedly connected inside the dust collection box 22.

[0025] After fixing the plastic part from which the gate needs to be removed, start the first drive motor 14 to drive the bidirectional threaded rod 15 to rotate. Since the thread on the bidirectional threaded rod 15 matches the internal thread of the connecting block 16, the position of the connecting block 16 can be adjusted. Then, start the electric telescopic rod 17 to adjust the height of the cutting blade 20. The second drive motor 19 runs to drive the cutting blade 20 to rotate, thus removing the excess gate on the plastic part. While cutting, the dust cover 18 can wrap the debris and reduce the range of debris diffusion. At the same time, start the fan 23 to suck the debris in the dust cover 18 into the dust collection box 22 through the dust collection box 22 and the dust collection pipe 21, thereby avoiding the situation of debris flying during cutting and thus avoiding injury to the human body.

[0026] Working principle: Pushing the two sets of clamping plates 8 outwards causes the first limiting plate 3 and support rod 4 to move into the first limiting groove 2, simultaneously compressing the return spring 6. Then, the plastic part to be degassed is placed between the two sets of clamping plates 8. Releasing the clamping plates 8 allows the return spring 6 to push the clamping plates 8 towards the surface of the plastic part, making them adhere to the surface, with the base plate 9 positioned at the bottom of the plastic part. The fixing bolts 7 are then screwed into the threaded holes 5 to secure the plastic part. The two sets of second limiting plates 11, driven by the two sets of clamping plates 8, move within the second limiting groove 10, adjusting the exposed length of the reinforcing plate 12. 8. Connect the parts to strengthen the outer wrapping of the plastic parts. Start the first drive motor 14 to drive the bidirectional threaded rod 15 to rotate. Adjust the position of the connecting block 16. Then start the electric telescopic rod 17 to adjust the height of the cutting blade 20. The second drive motor 19 runs to drive the cutting blade 20 to rotate, which can remove excess gates on the plastic parts. At the same time, start the fan 23 to suck the debris in the dust cover 18 into the dust collection box 22 through the dust collection box 22 and the dust collection pipe 21, so as to avoid the debris from flying during cutting and thus avoid injury to the human body.
