[0002] The plastic cover of the car dashboard is a plastic part used to decorate and protect the car dashboard. After the car dashboard is completed by injection molding and demolding, the flash on its side needs to be polished. The edges of the plastic cover after injection molding may have defects such as flash and burrs. These defects will affect the appearance quality of the product and may even affect its performance and safety. In order to improve the overall quality of the product and meet market demand, these flashes need to be polished to obtain smooth and neat edges.

[0025] Working principle: In use, when fixing the plastic cover of the automobile instrument panel, first push the plastic cover of the automobile instrument panel into the processing table 1. After the plastic cover of the automobile instrument panel moves a certain distance, the plastic cover of the automobile instrument panel can contact with the pushing block 48, so that the plastic cover of the automobile instrument panel can push the pushing block 48. When the pushing block 48 moves, the pushing block 48 can simultaneously drive the two positioning plates 42 to move inward through the two connecting rods 47, so that the alignment column 44 in the positioning plate 42 can contact with the plastic cover of the automobile instrument panel, so that The positioning plate 42 can clamp and fix the plastic cover of the automobile instrument panel, thereby ensuring that the plastic cover of the automobile instrument panel will not shake when the polishing rod 3 is polishing the plastic cover of the automobile instrument panel, and when the pushing block 48 moves, it can push the limit rod 51 to move, so that the limit rod 51 can move on the processing table 1, so that the limit block 52 on the surface of the limit rod 51 can cooperate with the toggle assembly 6, so that the toggle assembly 6 can block the position of the limit block 52, so that the compression spring 53 cannot push the limit rod 51 to move.

[0026] After the automobile instrument panel plastic cover plate is polished, the clamping block 65 can be moved by rotating the handle 66, so that the clamping block 65 can push the extrusion rod 63 to move downward, so that the extrusion rod 63 can push the positioning rod 61 to move, so that the positioning rod 61 can rotate, so that the positioning rod 61 is in contact with the limiting block 52, so that the compression spring 53 can push the limiting rod 51 to move, so that the limiting rod 51 can push the push block 48 out at the same time, so that the push block 48 can push the polished automobile instrument panel plastic cover plate out, and the next automobile instrument panel plastic cover plate is polished.
