The invention discloses an insulator dry-type cold isostatic pressing processing device and a mold cleaning brush thereof. The insulator dry-type cold isostatic pressing processing device comprises a high-pressure cylinder, a side mold, a bottom mold, a top mold, a top plug, a bottom plug and a matching part, wherein the side mold and the high-pressure cylinder are coaxially arranged, a side torsional spring is arranged between the outer wall of the side mold and the inner wall of the high-pressure cylinder, the top plug is located at the top part of the high-pressure cylinder, the top mold is in sliding fit with a sliding hole in the middle of the top plug, an upper sliding block is arranged in the top mold, the upper sliding block is connected with an upper piston through a connecting rod, and an upper torsional spring is arranged between the upper piston and the top mold. According to the insulator dry-type cold isostatic pressing device, raw material particles can be pressed from the side face, the top part and the bottom part through utilizing a high-pressure electromagnetic isostatic pressing treatment assembly, rapid and 'mild' demolding is completed, the interior of the side mold can be cleaned, the forming effect is good, automatic production can be achieved, the production efficiency is high, and the insulator dry-type isostatic pressing device has high application value.
Description
technical field [0001] The invention relates to the technical field of insulator production equipment, in particular to an insulator dry-type cold isostatic pressing treatment device and a mold cleaning brush thereof. Background technique [0002] Insulators are insulating ceramics used in high-voltage power lines and power stations, and are an important part of the power industry. The preparation of insulators includes the steps of formulation, powder grinding, embryo body preparation, molding, drying, glazing, sintering, etc., and isostatic pressing is often used to form the embryo body. [0003] Isostatic pressing is to add granulated ceramic materials into the mold. The material of the mold is generally plastic or rubber with certain elasticity. The granulated porcelain material in the mold is compacted and formed. There are two methods of isostatic pressing: cold isostatic pressing and hot isostatic pressing, and cold isostatic pressing is divided into wet and dry. D...
