Abstract

The present invention relates to the technical field of magnetic core processing, and aims to provide an E-shaped magnetic core molding die and a processing and molding method thereof. The main points of the technical solution are to include a lower mold, and a molding cavity is opened on the upper surface of the lower mold. Two sliding blocks are slidably connected on both sides of the forming cavity, and a horizontal fixing plate is fixedly connected to the top of the opposite side wall of the sliding block, and the width of the sliding block and the width of the fixing plate are equal to the width of the molding The width of the cavity is located directly above the lower die to be provided with a pressing device, the pressing device includes a hydraulic cylinder, the piston rod of the hydraulic cylinder is vertically downward and its end is fixedly connected with a briquetting block, the lower part of the briquetting block The surface is provided with an empty groove for molding the central column, and the molding die also includes a driving assembly for driving two sliding blocks. The invention facilitates demoulding of the magnetic core and effectively improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of magnetic core processing, more specifically, it relates to a molding die for an E-shaped magnetic core and a processing and molding method thereof. Background technique [0002] Ferrite core is a high-permeability material, mainly used as high-frequency transformer, high-frequency magnetic ring, inductor, etc., to increase the permeability and improve the quality factor of inductance. The ferrite core is wound with a coil It can be made into inductors or transformers. They are widely used in instruments, communication equipment and household appliances. The production of ferrite cores generally adopts mold casting, sintering and final grinding. [0003] In the process of processing the existing E-type magnetic core, the central column of the magnetic core and the two side plates are usually in a vertically downward state, which is inconvenient for demoulding. The body causes damage, resulting in an incre...
