Generally, injection molding, transfer molding, or injection molding is used to produce injection molding parts.

[0003] During the production process of injection molding parts, problems such as notches and burrs may occur. Some injection molding parts that do not affect use will be repaired manually, and fixtures will be used for clamping during the repair process. However, existing traditional fixtures are not suitable for repairing injection molding parts. When multiple points of an injection molding part need to be repaired, the clamping angle needs to be frequently changed, thus affecting the repair efficiency. Therefore, an auxiliary fixture for repairing injection molding parts is proposed. Summary of the Utility Model

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-3As shown in the figure, an injection molding part repair auxiliary fixture includes a clamping table 1 and two moving plates 21. The clamping table 1 has a "冂"-shaped structure. Two symmetrically distributed moving grooves 2 are formed on the clamping table 1. The two moving plates 21 are respectively slidably connected to the two moving grooves 2. A circular clamping plate 22 is rotatably connected to the top of each moving plate 21. A rotating shaft 23 is rotatably connected to both sides of the clamping table 1. Threaded sections 24 are provided at both ends of the rotating shaft 23. The two threaded sections 24 on the rotating shaft 23 are respectively threadedly connected to the two moving plates 21. One end of the rotating shaft 23 penetrates through the clamping table 1 and is coaxially connected to a handwheel 25. A control mechanism 3 is provided on the clamping table 1 for rotating and adjusting the clamped object.

[0019] In this embodiment, the control mechanism 3 includes a control rod 32 and a lifting rod 36. A communication port 31 is formed at the lower end of each moving plate 21. The control rod 32 is slidably connected to the moving plate 21, and the lower end of the moving plate 21 extends to the communication port 31. An annular groove 33 is coaxially formed on the side of each clamping plate 22 close to the moving plate 21. A gear ring 331 is connected to the inner ring of the annular groove 33. A sliding groove is formed on the moving plate 21 and a clamping block 34 is slidably connected thereto. One end of the clamping block 34 is connected to the control rod 32, and the other end of the clamping block 34 extends into the annular groove 33. Lifting grooves 35 are formed on both sides of the clamping table 1. The two lifting grooves 35 are jointly slidably connected to a lifting rod 36. Springs 37 are connected to the bottom surfaces at both ends of the lifting rod 36. The lower ends of the springs 37 are connected to the lifting grooves 35. The lower ends of the two control rods 32 are respectively slidably penetrated by the lifting rod 36.

[0020] In this embodiment, the two threaded sections 24 on the rotating shaft 23 have opposite thread directions and equal lengths. A rubber pad 221 is provided on the clamping surface of each clamping plate 22, and the rubber pad 221 has a large static friction coefficient, so that the fixture can better clamp the injection molding part and avoid sliding.

[0021] In this embodiment, mounting plates 11 are connected to the bottoms of both sides of the clamping table 1. Mounting holes are formed in each mounting plate 11, which facilitates the installation and disassembly of the entire fixture.

[0022] Working process and principle:

[0023] When the utility model is in use, the injection molded part is first placed between the two clamping plates 22, and then the rocker 25 is rotated to drive the rotating shaft 23 to rotate, and the two movable plates 21 are controlled by the thread to slide close to each other, so that the two clamping plates 22 complete the clamping of the injection molded part. During the repair process, when the angle of the injection molded part needs to be adjusted, it is only necessary to press the control rod 32 on one of the movable plates 21. When the control rod 32 moves down, it will squeeze the lifting rod 36 and pull the other control rod 32 down together. After the blocking blocks 34 on the two control rods 32 leave the gear ring 331, the rotation restriction of the clamping plate 22 is released, and then the clamping plate 22 is rotated to adjust the angle of the injection molded part. When it is rotated to a suitable angle, the pressure on the control rod 32 is released. Under the elastic force of the spring 37, the blocking block 34 moves up and contacts the gear ring 331, and the rotation of the clamping plate 22 is restricted again.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
