A polishing device for preparing plastic molds for TV shells

Abstract

The invention relates to a polishing device for television housing plastic mould preparation. The polishing device comprises a polishing box, polishing shafts, a driving motor, a rotating shaft, a blanking channel, a material box, grinding materials, a mounting frame, a limiting spring, a sliding block, a tooth missing wheel, a material pushing plate, a connecting rod, a mounting shaft and a rack;the rotating shaft is rotationally connected with the interior of the polishing box; the rotating shaft penetrates through the polishing box and is in transmission connection with the output end of the driving motor; the polishing shafts are arranged on the rotating shaft; the grinding materials are located in the material box; the sliding block is in sliding connection with the interior of the mounting frame; the rack is fixed to the top end of the sliding block; the tooth missing wheel is arranged on the mounting shaft; the rack is connected with the end surface of the left side of the interior of the mounting frame through the limiting spring; the material pushing plate is in sliding connection with the interior of the blanking channel; and the right end of the connecting rod penetrates through the side wall of the blanking channel and is fixedly connected with the material pushing plate. The polishing device is excellent in structure, reasonable in design and easy and simple to operate, the polishing effect is improved, the polishing efficiency is improved, the adaptability degree of equipment is high, the production cost is reduced, and the polishing device has the wide application prospect and high creativity.

Description

technical field [0001] The invention relates to the field of plastic mold processing equipment, in particular to a polishing device for preparing plastic molds for TV casings. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of eng...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a polishing device for preparing plastic molds for TV casings, so as to solve the disadvantages of the traditional plastic mold polishing equipment proposed in the background technology above, which puts molds and abrasives into the equipment, and then performs rough polishing. Yes, the weight of the abrasive and the mold are different, and there will be a drop in height, resulting in a small contact area between the abrasive and the mold. The contact area directly determines the degree of polishing and the quality of the polishing
