Abstract

The invention discloses an adjustable tightly packaged optical fiber extrusion molding mold. The mold comprises a mold sleeve and a mold core, wherein the mold sleeve is provided with a extrusion molding hole; the mold core comprises a mold core mouth part; the mold core mouth part is provided with a center lead-in hole; the center lead-in hole is provided with an adjustable fiber-guiding needle tube capable of moving forwards and backwards along the axial direction of the center lead-in hole; the outer wall of the adjustable fiber-guiding needle tube is matched with the inner wall of the center lead-in hole; the length of the fiber-guiding needle tube extending out of the center lead-in hole is adjusted, so that the type of the extrusion molding mold is changed. According to the adjustable tightly packaged optical fiber extrusion molding mold and by means of the above mentioned mode, the structure is simple and reasonable; the adjustable fiber-guiding needle tube is arranged in the mold core, and the relative positions of the needle tube and the core sleeve are adjusted, thus the extrusion mode of the extrusion molding mold is changed, and different product requirements are met; and the mold is convenient to adjust, easy to machine, reliable in performance and stable in size.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an adjustable optical fiber tight package extrusion mold. Background technique [0002] With the development of FTTH, the amount of indoor optical cables is increasing year by year. Tight-packed optical fibers are the core components of indoor optical cables and play a key role in affecting the performance of indoor optical cables. Tight-wrapped optical fiber extrusion molds are divided into extrusion molds, extruded tube molds and semi-extrusion extrusion molds. In order to meet the diverse requirements of different performances, structures and tight-wrapped materials, tight-wrapped optical cables have good transmission Performance, in the production process of tight-packed optical fiber, the requirements for molds are relatively high. Products with different performance requirements need to replace different types of extrusion molds, not only need various types of extrusion molds...
