[0002] Plastic production involves a variety of equipment, including plastic extruders and injection molding machines. These machines transform plastic raw materials into plastic products of various shapes and sizes through different process steps. The injection mold used in the injection molding machine is a tool for producing plastic products. It injects molten plastic into the mold cavity under high pressure, and after cooling and solidification, the molded product is obtained.

[0003] When processing plastic parts such as plastic sheets, the plastic sheets will become loose if they are not fixed on the workbench. Traditional clamps are usually set as one piece, which is not easy to adjust. Therefore, it is often necessary to change the size of the clamp according to the size of the plastic material, which has low applicability. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a fixing device for plastic production with positioning function, which solves the problem that traditional clamps are generally integrated and not easy to adjust. Therefore, it is often necessary to replace clamps of different sizes according to the size of the plastic raw materials, resulting in low applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for plastic production with positioning function, including a support frame, a plurality of support legs connected below the support frame, a placement platform connected above the support frame, a motor installed on one side of the support frame, a threaded rod connected to the output shaft of the motor, two movable plates installed on the threaded rod, threaded sleeves connected to the movable plates, a clamping plate connected above the movable plates, and irregular grooves formed on the clamping plate;

[0006] An adjusting screw is slidably connected inside the irregular groove. A positioning plate is connected to the adjusting screw, and a fastening nut is threaded onto the adjusting screw. A groove is provided on the placement platform. Guide rods are connected to the two sides of the placement platform that are recessed inward. Two electric push rods are installed in the groove. A movable plate is slidably installed in the groove. Multiple rollers are rotatably connected above the movable plate.

[0007] As a further embodiment of this utility model: the movable end of the electric push rod is connected to a connecting block, and connecting rods are connected to both sides of the connecting block, with the movable ends of the two electric push rods facing opposite directions.

[0008] As a further embodiment of this utility model: guide grooves are provided on both sides below the movable plate, the guide grooves are inclined, and the two ends of the connecting rod slide within the guide grooves.

[0009] As a further embodiment of this utility model: the two ends of the threaded rod are provided with threads in opposite directions, the threaded rod is rotatably connected to the support frame, and the threaded sleeve is threadedly engaged with the threaded rod.

[0010] As a further embodiment of this utility model: both the irregular groove and the positioning plate are L-shaped designs, one end of the positioning plate slides together with the adjusting screw in the irregular groove, and an anti-slip rubber layer is provided below the support leg.

[0011] As a further embodiment of this utility model: sliding holes are provided on both sides of the clamping plate, and the clamping plate is slidably connected to the guide rod through the sliding holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This positioning device for plastic production comprises a motor, threaded rod, movable plate, clamping plate, irregular groove, adjusting screw, fastening nut, and positioning plate. The operator starts the motor to rotate the threaded rod, causing the movable plate to move along the threaded rod using the threaded engagement of the threaded sleeve. The two movable plates then drive the two clamping plates to move in opposite directions, thus clamping and fixing the plastic sheet on both sides. The operator then tightens the fastening nut, causing the positioning plate and adjusting screw to slide along the irregular groove, allowing the positioning plate to contact the other two sides of the plastic sheet, thereby fixing the plastic sheet in place. The movable clamping plate and positioning plate accommodate different sized plastic sheets, eliminating the need for frequent fixture changes and improving applicability.

[0014] 2. This positioning device for plastic production, by setting up an electric push rod, connecting block, connecting rod, guide groove, movable plate and roller, allows the plastic sheet to contact both the placement table surface and the roller simultaneously when the plastic sheet is placed. When picking up the material, the operator activates the electric push rod, which pushes the connecting block to move, causing the two ends of the connecting rod to slide in the guide groove. Through the inclined guide groove, the connecting rod can push the movable plate to move upward, causing the roller to lift the plastic sheet. Thus, the rolling of the roller assists the operator in moving the plastic sheet, making it easier for the operator to pick up the moving plastic sheet. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a fixing device for plastic production with positioning function, including a support frame 1, multiple support legs 2 connected below the support frame 1, a placement platform 3 connected above the support frame 1, a motor 4 installed on one side of the support frame 1, a threaded rod 5 connected to the output shaft of the motor 4, two movable plates 6 installed on the threaded rod 5, and threaded sleeves 7 connected to the movable plates 6. The two ends of the threaded rod 5 are provided with threads in opposite directions. The threaded rod 5 is rotatably connected to the support frame 1. The threaded sleeves 7 are threadedly engaged with the threaded rod 5. Through the threads in opposite directions at both ends of the threaded rod 5, the two movable plates 6 can drive the two clamping plates 8 to move in opposite directions when the threaded rod 5 rotates, thereby positioning and fixing the plastic plate.

[0022] A clamping plate 8 is connected above the movable plate 6. Sliding holes 21 are provided on both sides of the clamping plate 8. The clamping plate 8 is slidably connected to the guide rod 14 through the sliding holes 21. When the movable plate 6 moves the clamping plate 8, the clamping plate 8 will slide along the guide rod 14 at the same time, thereby guiding the clamping plate 8 through the guide rod 14 and preventing the clamping plate 8 from tilting.

[0023] The clamping plate 8 has an irregular groove 9. Both the irregular groove 9 and the positioning plate 11 are L-shaped. One end of the positioning plate 11 slides in the irregular groove 9 together with the adjusting screw 10. The support leg 2 is provided with an anti-slip rubber layer. When the clamping plate 8 holds the plastic sheet, the operator can loosen the fastening nut 12 to allow the adjusting screw 10 and the positioning plate 11 to slide along the irregular groove 9, so that the positioning plate 11 contacts both sides of the plastic sheet. Then, the positioning plate 11 is fixed by tightening the fastening nut 12, which facilitates the positioning of subsequent plastic sheets of the same size.

[0024] An adjusting screw 10 is slidably connected inside the irregular groove 9. A positioning plate 11 is connected to the adjusting screw 10. A fastening nut 12 is threaded onto the adjusting screw 10. A groove 13 is provided on the placement platform 3. The two sides of the placement platform 3 are recessed inward and connected to guide rods 14. Two electric push rods 15 are installed in the groove 13. The movable end of the electric push rod 15 is connected to a connecting block 18. The two sides of the connecting block 18 are connected to connecting rods 19. The movable ends of the two electric push rods 15 face opposite directions. When the movable plate 16 is embedded in the groove 13, the roller 17 will be flush with the surface of the placement platform 3, so that the plastic plate can be placed stably.

[0025] A movable plate 16 is slidably installed in the groove 13. Multiple rollers 17 are rotatably connected above the movable plate 16. Guide grooves 20 are provided on both sides below the movable plate 16. The guide grooves 20 are inclined. The two ends of the connecting rod 19 slide in the guide grooves 20. Through the inclined guide grooves 20, when the connecting rod 19 moves along the guide grooves 20, it can push the movable plate 16 through the groove wall of the guide grooves 20, thereby completing the upward or downward movement of the movable plate 16.

[0026] The working principle of this utility model is as follows:

[0027] After placing the plastic sheet on the placement platform 3, the motor 4 is started to rotate the threaded rod 5, causing the moving plate 6 to move along the threaded rod 5 using the threaded sleeve 7, which in turn moves the clamping plate 8. This clamping plate 8 clamps and fixes the two sides of the plastic sheet. Then, by loosening the fastening nut 12, the positioning plate 11 and the adjusting screw 10 slide along the irregular groove 9, allowing the positioning plate 11 to contact the other two sides of the plastic sheet. At this time, the fastening nut 12 is tightened to fix the positioning plate 11, thereby positioning and fixing the plastic sheet. When picking up the material, the worker starts the electric push rod 15, which pushes the connecting block 18 to move, causing the two ends of the connecting rod 19 to slide in the guide groove 20. The inclined guide groove 20 allows the connecting rod 19 to push the movable plate 16 upward, causing the roller 17 to lift the plastic sheet. Thus, the rolling of the roller 17 assists the worker in moving the plastic sheet.
