[0002] Injection molded parts refer to various injection products produced by injection molding machines, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. The choice of plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Injection molded parts are generally made by compression molding, transfer molding, and injection molding. Lamination, compression molding and thermoforming are to shape plastics on a plane. The above methods can all be used for rubber processing. After the processing of automotive injection molded parts is completed, polishing devices are usually used for polishing. The existing polishing devices mainly use roller brushes to rotate at high speed on the surface of the injection molded parts, so that the rotating roller brushes grind the burrs and other excess parts on the injection molded parts. However, due to the different sizes of burrs, the use of a single roller brush for polishing will affect the quality of the injection molded parts. For this reason, we provide a polishing device for automotive injection molded parts to solve the above problems. Utility Model Content

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0014] The utility model proposes a polishing device for automobile injection molded parts, comprising a bottom shell 1, four corners of the top of the bottom shell 1 are fixedly provided with columns 2, top plates 3 are fixedly provided on the tops of the multiple columns 2, the bottom shell 1, the columns 2 and the top plates 3 can form a support frame of the entire polishing device, an electric slide 9 is installed in the inner cavity of the bottom shell 1, a slide plate 4 is fixedly provided on the slider of the electric slide 9, the top of the slide plate 4 is used to carry the injection molded parts, and the injection molded parts can be driven to move laterally under the operation of the electric slide 9, and the internal through-type fixed plate 3 is provided. A cylinder 5 is fixedly provided, and a mounting frame 6 is fixedly provided at the movable end of the cylinder 5. Two rotating shafts 7 are rotatably provided inside the mounting frame 6, and the two rotating shafts 7 are connected with driving components. Roller brushes 8 are sleeved on the outer walls of the two rotating shafts 7. The cylinder 5 can drive the roller brush 8 inside the mounting frame 6 to contact the injection molded part. When the roller brush 8 rotates, the injection molded part can be driven for polishing. The two roller brushes 8 are respectively a coarse roller brush and a fine roller brush, thereby realizing graded polishing of the injection molded part, and further controlling the polishing quality of the injection molded part.

[0015] Specifically, a motor 16 is installed on one side of the outer wall of the mounting frame 6, and the output end of the motor 16 is fixedly connected to the axial end of one of the rotating shafts 7. The ends of the two rotating shafts 7 away from the motor 16 are fixedly connected to a groove wheel 12, and the outer walls of the two groove wheels 12 are movably connected with a belt 13. By utilizing the connection between the groove wheel 12 and the belt 13, the motor 16 can drive the two roller brushes 8 to rotate synchronously.

[0016] Specifically, two electric push rods 10 are correspondingly arranged on the top of the slide plate 4, and clamping plates 11 are fixedly arranged at the movable ends of the two electric push rods 10. The electric push rods 10 can push the two clamping plates 11 to approach each other and clamp the injection molded part.

[0017] Specifically, two rod bodies 14 are arranged in parallel in the inner cavity of the bottom shell 1 , and both rod bodies 14 are movable and penetrate the interior of the slide plate 4 . The design of the rod bodies 14 can limit the movement of the slide plate 4 , thereby increasing the stability of the movement of the slide plate 4 .

[0018] Specifically, sliding sleeves 15 are fixedly provided at the four corners of the mounting frame 6, and the sliding sleeves 15 are slidably connected to the outer walls of the corresponding columns 2. Since the volume of the mounting frame 6 is large, the connection stability of the single cylinder 5 is poor, so the stability of the mounting frame 6 is increased by the sliding connection between the sliding sleeves 15 and the columns 2.

[0019] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0020] Working principle: first, place the injection molded part on the top of the slide plate 4 and start the electric push rod 10. Under the action of the electric push rod 10, the two clamps 11 can be pushed closer to each other and the injection molded part can be clamped and fixed. Then, the cylinder 5 is started according to the height of the injection molded part. Under the operation of the cylinder 5, the roller brush 8 inside the mounting frame 6 can be driven to contact the injection molded part. Then, the motor 16 is started, and through the connection between the groove wheel 12 and the belt 13, the operation of the motor 16 can drive the two roller brushes 8 to rotate synchronously, and the operation of the electric slide 9 can drive the injection molded part on the top of the slide plate 4 to move horizontally, so that the injection molded part can be roughly polished at the bottom of the rough processing roller brush 8. Then, the electric slide 9 can drive the injection molded part to move to the bottom of the fine roller brush 8 for fine polishing. This graded polishing method can further control the polishing quality of the injection molded part.
