Integrated mold structure and method used for optical fiber

Abstract

The invention relates to the technical field of production of optical fibers, in particular to an integrated mold structure and method used for an optical fiber. By arranging at least one optical fiber channel and at least one reinforcer channel in a mold core main body in an axial direction, the optical fiber and a reinforcer can be punched, an external environment which can be observed with human eyes is introduced, thus accurate threading and guiding are facilitated, the front end portion of the mold core main body matches a conical hole of a mold sleeve to form a conical runner, an annularrunner is formed in the mold sleeve to achieve double-jacketed extrusion molding, thus the debug time is effectively saved, the production efficiency is improved, and double-layer extrusion molding can be achieved without shunt grooves, so that the production cost is reduced; and by means of a straightening mechanism, the optical fiber and the reinforcer can be straightened online, so that shaping effects of double-layer jackets are guaranteed.

Description

technical field [0001] The invention relates to the technical field of optical cable production, and relates to an integrated mold structure and method for optical cables. Background technique [0002] In the current optical cable manufacturing process, split molds are usually used in the extrusion process. It is difficult to adjust the eccentricity of the sheath, which is time-consuming, resulting in low efficiency and high cost. When forming two different sheath materials, it is generally realized through the shunt groove. After changing the material, the cost of changing the shunt groove is high, and it cannot meet the different needs of customers for materials. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of one-piece assembly for optical cables that effectively saves debugging time, improves production efficiency, realizes double-layer extrusion without the need for splitter slots, reduces producti...

[0002] In the current optical cable manufacturing process, split molds are usually used in the extrusion process, and the eccentricity of the sheath is difficult to adjust, which is time-consuming, resulting in low efficiency and high cost.

When forming two different sheath materials, it is generally realized through a splitter tank. After changing the material, the cost of changing the splitter tank is high, and it cannot meet the different needs of customers for materials.
