Description

Technical Field

[0001] This application relates to the field of injection molded part polishing, and more specifically, to an injection molded part surface polishing apparatus. Background Technology

[0002] Injection molded parts are workpieces produced by injection molding. Their raw materials are usually rubber and plastic. Due to their advantages such as high molding efficiency, precise dimensions and easy processing, injection molded parts are widely used in many industries.

[0037] Specifically, the working principle of this injection molding surface polishing device is as follows: During use, the injection molding part to be polished can be placed on the base 100, between the fixed clamping plate 111 and the movable clamping plate 114. Then, the handwheel 1131 and the threaded rod 113 are rotated. The threaded rod 113 pushes the movable clamping plate 114 towards the fixed clamping plate 111, thereby clamping and fixing the injection molding part between the movable clamping plate 114 and the fixed clamping plate 111. Then, the two first electric slides 210 are opened, causing the isolation box 220 to move downwards, covering the outside of the fixed clamping plate 111, the fixed plate 112, the threaded rod 113, and the movable clamping plate 114. The bottom wall of the isolation box 220 is in contact with the upper surface of the base 100. Then, the two electric push rods 240 are opened, driving the two second electric slides 230, the connecting plate 231, the rotating tube 250, and the suction tube 250. The grinding disc 270 moves downwards, allowing it to contact the upper surface of the injection molded part. Then, the motor 260 is turned on to rotate the rotating tube 250 and the grinding disc 270, polishing the upper surface of the injection molded part. The grinding disc 270 can then be moved along the upper surface of the injection molded part via two second electric slides 230. During the polishing process, the vacuum cleaner 290 is turned on. The vacuum cleaner 290 uses a telescopic hose 291, connecting pipe 292, rotating tube 250, and several suction pipes 280 to extract the injection molded part powder and debris from the isolation chamber 220. External air enters the isolation chamber 220 through the passage 221, thus isolating and collecting the injection molded part powder and debris generated during polishing. This prevents the powder and debris from scattering and reduces their adverse impact on the surrounding environment, demonstrating high practicality.
