Optical fiber cabling die

Abstract

The invention relates to an optical fiber cabling die which comprises a die sleeve and a die core. A die core plug-in is inserted in an axial conical hole in the center of the die core and internallyand axially provided with at least one optical fiber channel and at least one reinforcer channel; an optical fiber guiding protective tube is fixedly mounted in each optical fiber channel; the die sleeve is provided with a conical hole; the front end of the die core is in a conical shape and is matched with the conical hole of the die sleeve to form a conical flow passage which is communicated with the reinforcer channels; the front end of die core plug-in is arranged in the die core; each optical fiber guiding protective tube penetrates through both ends of the die core plug-in; and the frontend of each optical fiber guiding protective tube extends forwards to a position between an inner port and an outer port of an extrusion hole of the die sleeve. The optical fiber cabling die processes a bare optical fiber into an optical fiber and enables melted plastics to not only tightly wrap the reinforcer, but also avoid damaging the bare optical fiber in a cabling process, thereby ensuringthe quality of the processed optical fiber.

Description

technical field [0001] The invention relates to an optical fiber cable forming mold. Background technique [0002] At present, the molds used in the production of optical cables generally include extrusion molds and extrusion molds. Extrusion molds such as figure 1 As shown, the mold core 2 and the mold sleeve 1 are separated by a suitable gap, and the molten plastic flows through the conical flow channel formed by the two, and has been in contact with the cable core before the mold is ejected; Horizontally, a great pressure is formed in the direction of the vertical cable core, and this pressure can wrap the cable core tightly. extruded tube die figure 2 As shown, the front end of the mold core 4 has a fixed-length sleeve bearing diameter 5, and the bearing diameter part is inserted into the inner hole of the mold sleeve 3, and is flush with the front end of the mold sleeve 3; The mold is ejected, and the molten plastic is ejected from the annular flow channel between t...

Problems solved by technology

[0005] The purpose of the present invention is to provide an optical fiber cabling mold that utilizes bare optical fibers to process optical cables and at the same time adds reinforcements, so as to solve the technical problem that the existing cabling molds cannot directly use bare optical fibers to process optical cables equipped with reinforcements
