Self-supporting wire cable jacket extrusion mold

Abstract

The invention relates to a self-supporting optical cable and cable jacket extrusion mold which comprises a mold core unit and a mold cover unit, wherein a line-hanging mold core post, a cable core mold core post, a mold core body, a fixing clamp part and a fixing part are arranged on the mold core unit, and a mold core cavity is arranged in the mold core unit; both the line-hanging mold core postand the cable core mode core post are internally provided with holes communicated with the mold core cavity, and the mold core unit is of a integral structure; the mold cover unit comprises a material discharge end and a mold cover body which is internally provided with a mold sleeve cavity; the material discharge end is provided with a line-hanging protection layer discharge hole, an outer protection layer discharge hole and a strip-hanging hole; and the strip-hanging hole is connected with the line-hanging protection layer discharge hole and the outer protection layer discharge hole and communicated with the mold sleeve cavity. In the invention, because the mold core body and the mold sleeve cavity have reasonable design, the mold core unit is perfectly matched with the mold cover unit,a self-supporting cable produced with the mold has more smooth appearance and evener thick distribution of the jacket; the mold is more wearable, and the product qualification ratio is higher.

Description

technical field [0001] The invention relates to a cable sheath extrusion mold, especially a self-supporting light and cable sheath extrusion mold. Background technique [0002] Self-supporting optical cables and cables are usually used for overhead laying. They generally consist of two parts: the upper part is a suspension wire, which is composed of steel wire ropes or multiple twisted non-metallic reinforcements, and a suspension wire sheath is extruded outside it; The part is composed of optical and cable cores, and the cable core is extruded with an outer sheath; the upper part and the lower part are connected by a sling; the suspension wire sheath, sling, and outer sheath are integrally extruded; The material of the cable core is different. Therefore, when the mold design is poor, the cable will often have a bad appearance during and after extrusion, which is difficult to meet the requirements of use, and the product will be scrapped if it is serious.
