Injection mold convenient for regulating diameter of cable sheath

Abstract

The invention relates to the technical field of production equipment for cables, and particularly discloses an injection mold convenient for regulating a diameter of a cable sheath. The injection moldcomprises an inner module, an intermediate module and an outer module, wherein the inner module, the intermediate module and the outer module are in threaded connection in sequence from top to bottom; the inner module, the intermediate module and the outer module are all of conical structures; the top position of the inner module is provided with a threaded connecting base; the bottom position ofthe inner module is provided with a threading pipe; a first injection mold cavity is formed between the inner module and the intermediate module; a second injection mold cavity is formed between theintermediate module and the outer module; the upper position of the intermediate module is provided with a first injection pipe joint communicated with the first injection mold cavity; and the upper position of the outer module is provided with a second injection pipe joint communicated with the second injection mold cavity. Problems that a conventional injection mold for the cable sheath can be only used for performing injection on the cable sheath with a single diameter in a use process, the re-centering is needed after the diameter of the cable sheath needing to be subject to the injectionis changed, and time is greatly wasted are solved.

Description

technical field [0001] The invention relates to the technical field of cable production equipment, in particular to an injection mold for conveniently adjusting the diameter of a cable sheath. Background technique [0002] In the production of wire and cable products, the extrusion die often plays a vital role in the quality of the product, and directly determines the appearance of the product. Existing extrusion dies are two-body structure of inner mold and outer mold. According to the distance between the inner and outer molds and the outlet, extrusion, semi-extrusion, extruded tube and semi-extruded tube structures are formed. Way. [0003] In the process of using the traditional cable sheath injection mold, it can only inject the cable sheath with a single diameter. After changing the diameter of the cable sheath, it needs to be re-centered, which is a waste of time. Contents of the invention [0004] (1) Solved technical problems [0005] In order to solve the abov...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, the present invention provides an injection mold for conveniently adjusting the diameter of the cable sheath, which solves the problem that the traditional cable sheath injection mold can only inject a cable sheath with a single diameter during use. The diameter of the cable jacket that needs to be injected needs to be re-centered afterwards, which is a very time-consuming problem
