Problems solved by technology

[0002] In the past, the magnetic cores of open-type transformers were produced by means of internal mold setting, which could not effectively guarantee the outer circle size of the magnetic cores, and could not deal with the problem of cracks on the end faces of the magnetic cores (such as Figure 5 As shown), it will make it difficult for the magnetic core to cooperate with the protective box or other fixtures in the subsequent assembly, and it will also affect the material properties of the open transformer

Abstract

A shaping outer mold structure provided by the present invention comprises a first clamping piece and a second clamping piece which are arranged at the two sides, the first clamping piece and the second clamping piece are connected with an elastic piece, and a clamping space is formed between the first clamping piece and the second clamping piece. The elastic piece is linked with each first clamping piece and each second clamping piece to be close to each other, so that the clamping space has a narrowing trend. Through the arrangement of the shaping outer mold structure, a magnetic core of a mutual inductor can be effectively subjected to shaping application, so that the magnetic core manufactured by the shaping outer mold structure is ensured to be stably assembled in the open-type mutual inductor, and the application requirement of the open-type mutual inductor is met.

Description

technical field [0001] The invention relates to a shaping mold, in particular to a shaping outer mold structure. Background technique [0002] In the past, the magnetic cores of open-type transformers were produced by means of internal mold setting, which could not effectively guarantee the outer circle size of the magnetic cores, and could not deal with the problem of cracks on the end faces of the magnetic cores (such as Figure 5 As shown), it will make it difficult for the magnetic core to cooperate with the protective box or other fixtures in the subsequent assembly, and it will also affect the material properties of the open transformer. Contents of the invention [0003] The purpose of the present invention is to provide a sizing outer mold structure to overcome the deficiencies of the prior art. [0004] The external mold structure for shaping includes a first clamping piece and a second clamping piece arranged on both sides, the first clamping piece and the second...
