Cable tooling mould

A cable worker and mold technology, applied in cable/conductor manufacturing, circuits, electrical components, etc., can solve the problems of prolonging the flow time of cable cell cladding materials, shortening the time of cable plastic flow, and large cable mold volume. To achieve the effect of shortening the volume, easy disassembly and assembly of the taper, and large amount of glue

Problems solved by technology

[0006] The invention solves the problem that the cable mold in the prior art has a large volume, which makes the time for the cladding material of the cable core to flow in the mold to be prolonged, resulting in poor fluidity of the cladding layers of different layers, and provides a return-type flow guide The grooved cable tooling mold reduces the volume of the mold, shortens the length of the mold, shortens the time for the cable plastic to flow in the mold, and maintains the fluidity of the cladding material

Abstract

The invention relates to a cable tooling mould, which is used for coating plastics for cables and solves the problems that the size of a cable mould in the prior art is large, accordingly, the flowing time of cable core covering materials in the mould is prolonged, and different covering layers are poor in flowability. A sheath glue channel is arranged on the outer surface of a mould core base and connected with a cable sheath extruding machine, a tapered returnable conducting layer glue channel is arranged on the outer surface of a glue channel sleeve, an inlet of the tapered returnable conducting layer glue channel is arranged between two lateral ends of the tapered returnable conducting layer glue channel, and materials flow to one side of the tapered returnable conducting layer glue channel close to a feeding end of the mould core base from the inlet and then return to the other side of the tapered returnable conducting layer glue channel to flow out. As the tapered returnable conducting layer glue channel is arranged on the outer surface of the glue channel sleeve, the flow distance of the cable covering materials is changed to meet requirements. Moreover, the area of the surface of the glue channel sleeve is reasonably used by the tapered returnable conducting layer glue channel, so that the overall size of the cable tooling mould can be reduced.

Description

technical field [0001] The invention relates to a tooling mold, in particular to a tooling mold for wrapping cables with plastic. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. [0003] The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In just a few decades of reform and opening up, China's cable manufacturing industry The huge production capac...
