Polishing device for plastic mold machining

Abstract

The invention discloses a polishing device for plastic mold machining. The device comprises a polishing box, a first motor is fixed to the upper portion of the inner bottom wall of the polishing box, rotating cavities are formed in the inner walls of the two sides of the polishing box correspondingly, first threaded rods are rotationally connected into the rotating cavities correspondingly, and the first threaded rods are connected with the first motor through a transmission mechanism; and a bottom plate is connected into the polishing box in a sliding manner through a sliding way, and a clamping mechanism used for clamping a mold is arranged on the bottom plate. By arranging a lifting mechanism, an adjusting mechanism and a connecting mechanism, multidirectional polishing of the mold can be achieved, the applicability of the polishing device is improved, the polishing effect of the polishing device is enhanced, and by arranging the transmission mechanism, the clamping mechanism and a fixing mechanism, the mold needing to be ground can be stably fixed; and the mold can be lifted through the bottom plate, so that the polishing device can be suitable for workers with different heights to operate, and the operability of the polishing device is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a grinding device for plastic mold processing. Background technique [0002] 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 engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into...

AI Technical Summary

Problems solved by technology

[0003] When processing rubber products, molds are needed. The mold is cast from metal materials. After casting, a semi-finished mold will be obtained. The semi-finished mold needs to be processed before it can be used. A grinding device will be used during the processing. The existing grinding device Most of the grinding blocks are directly fixed and cannot be adjusted in multiple directions during the grinding process, so the grinding effect is poor, and the mold is poorly fixed during the grinding process, and often moves to cause grinding failure
