Three-color wire cable jacket extrusion mold

Abstract

The invention relates to a wire cable jacket extrusion mold, in particular to a three-color wire cable extrusion mold, comprising a mold core unit (1), a first mold cover unit (2) and a mold sleeve unit (3). The three-color cable jacket extrusion mold is characterized by further comprising a second mold cover unit (4), a plurality of flow guiding rods (6) and a fluid director (5); and the axes ofa color distribution hole (34) and the axes of the first mold cover unit (2) form an included angle larger than 5 DEG and less than 175 DEG. The three-color wire cable extrusion mold solves the problem in one-step extrusion of three color marks at one pipeline or the out surface of one wire cable. The invention is easy to install and adjust and coincides with the principle of thick fluid hydromechanics better; and with even distribution of color strips, produced optical cables, cables and pipelines are more attractive.

Description

technical field [0001] The invention relates to a cable sheath extrusion mold, especially a three-color cable sheath extrusion mold. Background technique [0002] Optical and electrical cables are usually used for overhead, pipeline, and direct buried laying. With the continuous development and growth of the communication industry, multiple cables will be laid in the same tower or the same pipeline, and these cables will belong to different operations. Because the appearance of the cables is black, it is very inconvenient for maintenance. Therefore, eye-catching signs are required, usually by making the outer skin of the cables into different colors; however, because colored cables are expensive, And it cannot effectively prevent ultraviolet radiation, so operators need to have colored stripes on the outer skin of a single cable. Moreover, as the business volume of operators increases, only two colors are used to distinguish a single sheath, which cannot meet the requiremen...

Problems solved by technology

[0002] Optical and electrical cables are usually used for overhead, pipeline, and direct buried laying. With the continuous development and growth of the communication industry, multiple cables will be laid in the same tower or the same pipeline, and these cables will belong to different operations. Because the appearance of the cables is black, it is very inconvenient for maintenance. Therefore, eye-catching signs are required, usually by making the outer skin of the cables into different colors; however, because colored cables are expensive, And it cannot effectively prevent ultraviolet radiation, so operators need to have colored stripes on the outer skin of a single cable

Moreover, with the increase of the business volume of operators, only two colors are used to distinguish a single sheath, which cannot meet the requirements of quick identification.
