Description

Technical Field

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

[0002] Injection molded parts refer to all kinds of injection molded products produced by injection molding machines. Due to insufficient pressure during injection molding in the mold or other reasons, the injection molded parts may have defects when they are produced. Therefore, it is necessary to polish the injection molded parts.

[0003] Currently, most injection molded parts are polished manually by workers, but this is time-consuming, inefficient, and often wastes a lot of manpower. Manual polishing also easily leads to hand injuries for workers.

[0004] To address this, a grinding device for injection molded parts processing is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for injection molded parts processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for injection molded parts, comprising a base plate, wherein a rotating shaft is symmetrically rotatably connected to one side above the base plate, and a grinding belt is installed on the rotating shaft;

[0007] A cylinder gripper is slidably connected to the other side above the base plate. Two gripper plates are symmetrically installed on the cylinder gripper. Gears are rotatably connected to the gripper plates via a shaft. One end of the shaft passes through the gripper plate and is fitted with a clamping plate.

[0008] The gripper plate is equipped with a limiting tooth plate that restricts the position of the gear.

[0009] Preferably, a slide rail is installed above the base plate, a slide block is slidably connected to the slide rail, and the cylinder gripper is installed on the slide block.

[0010] Preferably, a housing is mounted on the gripper plate, and a connecting rod is slidably connected inside the housing, the connecting rod being fixedly connected to the limiting tooth plate.

[0011] Preferably, a spring for resetting the connecting rod is installed inside the housing.

[0012] Preferably, a pull rod is installed on the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the injection molded part is clamped and fixed by the cylinder gripper, and then the injection molded part can be polished by the polishing belt. At the same time, the position of the injection molded part can be adjusted by the cooperation of the limiting gear and the gear, which facilitates the overall polishing work. This device avoids the process of workers holding the injection molded part by hand for polishing, thus improving safety. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a grinding device for injection molding parts, including a base plate 1, a rotating shaft 2 symmetrically rotatably connected to one side above the base plate 1, and a grinding belt 3 installed on the rotating shaft 2;

[0020] On the other side above the base plate 1, a cylinder gripper 6 is slidably connected. Two gripper plates 8 are symmetrically installed on the cylinder gripper 6. A gear 7 is rotatably connected to the gripper plate 8 through a shaft. One end of the shaft passes through the gripper plate 8 and is fitted with a clamping plate 12.

[0021] A limiting toothed plate 11 is installed on the gripper plate 8 to restrict the position of the gear 7.

[0022] like Figure 1 and Figure 2 As shown: A slide rail 4 is installed above the base plate 1, and a slide block 5 is slidably connected to the slide rail 4. The cylinder gripper 6 is installed on the slide block 5. With the above settings, the cooperation between the slide rail 4 and the slide block 5 can more conveniently drive the cylinder gripper 6 to move.

[0023] like Figure 3As shown: A housing 9 is installed on the gripper plate 8, and a connecting rod 10 is slidably connected inside the housing 9. The connecting rod 10 is fixedly connected to the limiting tooth plate 11. With the above configuration, the connecting rod 10 can drive the limiting tooth plate 11 to move, thereby allowing the limiting tooth plate 11 to separate from and mesh with the gear 7.

[0024] like Figure 3 As shown: A spring is installed inside the housing 9 to reset the connecting rod 10; with the above settings, the limiting tooth plate 11 can be automatically reset and mesh with the gear 7 after the pull rod is released.

[0025] like Figure 3 As shown: A pull rod is installed on the connecting rod 10; with the above settings, the connecting rod 10 can be moved more conveniently and quickly.

[0026] Working principle: First, the injection molded part to be polished is placed between two clamping plates 12. Then, the cylinder clamping jaw 6 is controlled to move the two clamping jaw plates 8 to clamp the injection molded part. Then, the cylinder clamping jaw 6 is moved by the slide rail 4 and slide seat 5, which moves the injection molded part towards the polishing belt 3. The polishing belt 3 polishes the injection molded part. When one side of the injection molded part is polished, the connecting rod 10 is pulled to separate the limiting tooth plate 11 from the gear 7. Then, the gear 7 is rotated to adjust the position of the injection molded part. This allows for adjustment of different positions of the injection molded part, completing the overall polishing work.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
