Description

Polishing mechanism for injection molding products Technical Field The utility model relates to the technical field of plastic product polishing, in particular to an injection molding product polishing mechanism. Background After injection molding, the surface of the plastic product is not smooth enough, and the plastic product needs to be polished by a polishing machine, so that the glossiness or transparency of the plastic product is improved, and the quality of the plastic product is improved. In the related art, through retrieving the discovery, a scheme of injection molding product burnishing device (bulletin number CN 222308434U), place between two splint through injection molding product, the output flexible control connecting plate through the cylinder drives the butt joint board and removes, the butt joint board can drive the fly leaf and remove, then carry out propelling movement polishing to injection molding product, simultaneously the staff grips the driving lever and pulls, can drive the pivot rotation, the pivot rotation can drive splint rotation, then injection molding product rotation, make things convenient for the different faces of injection molding product to carry out the burnishing and polishing operation with the cooperation of grinding wheel. However, the clamping of above-mentioned scheme to injection molding product relies on manual operation, and operation driving lever also has the risk of damaging the hand when polishing, because injection molding product is in under the polishing wheel, controls the space limited when scribbling polishing wax, and is inconvenient inadequately, and polishing wheel size is fixed, is difficult to use the polishing of different injection molding products. Disclosure of utility model The utility model aims to provide an injection molding product polishing mechanism for solving the problems in the background art. In order to achieve the aim, the injection molding product polishing mechanism comprises a support, wherein a top frame is fixedly connected to the support, conveyors are arranged on the inner wall of the support and the top frame, a first cylinder is arranged on the top frame, the conveyors can automatically convey injection molding products, manual operation is reduced, and the conveying of the products is safer; The motor is connected with the first cylinder, the motor is connected with a polishing pad through an eccentric mechanism, the eccentric mechanism controls the polishing pad to translate, the polishing pad achieves polishing of injection products, the polishing pad translates can enlarge polishing range, and the polishing device can adapt to injection products with different sizes; The wax spraying pipe is arranged on the support and the conveyor, and the wax spraying pipe automatically sprays polishing wax on products, so that the polishing effect is improved, and the polishing wax is not required to be manually smeared.
