Filter extrusion molding winding die

Abstract

The invention discloses an extrusion forming winding mold for a filter. The mold comprises a base, a mold core assembly and a plate cover assembly, wherein the mold core assembly comprises a mold core base installed in the base, a first mold core and a second mold core which are symmetrically installed in the mold core base, a containing space for containing a carrier needing winding is formed among a first mold core, a second mold core and a split block, the upper end face of the first mold core and the upper end face of the second mold core form a first stepped groove and a second stepped groove for communicating the containing space formed by the inner walls of the two sides of the mold core base, and the plate cover assembly comprises a first plate cover and a second plate cover which are symmetrically installed on the base and move in a reciprocating mode. The first plate cover and the second plate cover cover the first stepped groove and the second stepped groove respectively to form wires to penetrate through a J-shaped or inverted J-shaped first wire inlet channel and a J-shaped or inverted J-shaped second wire inlet channel. The extrusion forming winding mold is compact in structure and can be directly extruded and formed to form two coils on a closed type annular carrier to form a filter, the working efficiency is high and the product quality is good so that the high market competiveness can be achieved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of winding die products, in particular to a winding die for extrusion molding of a filter. [0003] Background technique: [0004] As the name suggests, a filter is a device that filters waves. The function of the filter is to allow a certain part of the frequency signal to pass through smoothly, while the other part of the frequency signal is greatly suppressed or filtered out. It is essentially a frequency selection circuit. [0005] With the development of computer technology and communication technology, filters have been widely used in electronic products, and filters are used in basically every electronic product. A filter generally includes a closed loop carrier and an inductance coil wound on the closed loop carrier. [0006] When making the filter with the above structure, the traditional manufacturing method is to wind the enameled wire on the closed annular carrier by manual winding, so t...

Problems solved by technology

However, this production method is cumbersome, and the work efficiency is low, and the stability of the structure after the two components are combined to form a closed ring carrier needs to be considered, so that the quality of the entire filter is not ideal.
