Fuse insulator mold

Abstract

The invention relates to the technical field of dies for electric power, and discloses a fuse insulator die which comprises a bottom die, the top edge of the bottom die is fixedly connected with a sealing frame, the top of the bottom die is fixedly connected with a top die, and the bottom edge of the top die is in lap joint with the top of the sealing frame. Mold core cavities are formed in the opposite sides of the bottom mold and the top mold, and mold cores are arranged in the mold core cavities in a sleeved mode. Through the surface finishing mechanism, when a gear set drives a second half gear to rotate, a first plate gear and the second half gear form a gear ring, so that the gear set drives the gear ring to rotate, and due to the fact that a first half ring piece and a second half ring piece on the inner wall of the gear ring make contact with the surface of the insulator, the surface of the insulator is trimmed. The smooth layers on the inner walls of the first semi-ring piece and the second semi-ring piece can rub the surface of a molded product during rotation, so that the surface of the molded product can be smoothed, the molding quality can be improved, and demolding operation can be rapidly achieved.

Description

technical field [0001] The invention relates to the technical field of molds for electric power, in particular to a fuse insulator mold. Background technique [0002] Molds are 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 engineering plastics, rubber, ceramics...

AI Technical Summary

Problems solved by technology

[0003] When the fuse insulator is shaped, it is mainly poured with a mold, and then the cast molded product is fired to make the insulator form a standard that can be used, but when it is poured with a mold, due to the influence of the mold The tightness between the mold and the lower mold is affected by heat, and there will be residual material at the pouring joint, so the mold after production needs to be polished, which increases the follow-up process and easily leads to an increase in the scrap rate
