Alignment-free Headphone cable extrusion mold system and manufacturing method of headphone cable extrusion mold system

Abstract

The invention discloses an alignment-free headphone cable extrusion mold system and a manufacturing method of the headphone cable extrusion mold system. The mold system comprises a mouth mold, a guide cone and a mold core arranged between the mouth mold and the guide cone; during manufacture, the mouth mold and the mold core are clamped once, processed once and integrally assembled, and the coaxiality of a mold hole and a mold core hole is greatly guaranteed, so that a cable core can be accurately positioned in the center of the mold hole through the mold core hole, the alignment work of a conventional mold is avoided, a cable core jacket is uniform, a produced product quality is stable, the consistency is good, the boot time is shortened, the productivity and the success rate of one-time boot are increased, the cost can be effectively saved, the mold core can be replaced according to different cable cores, cables and wear conditions, and use and maintenance are very convenient.

Description

technical field [0001] The invention relates to a centering-free extrusion mold system for earphone wires and a manufacturing method thereof. Background technique [0002] Over the years, the extrusion molds for earphone wires used have adopted a matching structure in which the guide cone is radially fixed and axially adjustable, while the die can be adjusted in four directions in the radial direction. Although the mold processing technology of this structure is simple , but in the production process, it is necessary to manually adjust the eccentricity of the core wire to achieve the uniform and consistent radial thickness of the core wire outer jacket, which brings many problems such as huge consumption of raw materials. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an alignment-free extrusion mold system for earphone wires and a manufacturing method thereof. [0004] The technical solution adopt...
