Problems solved by technology

However, with the continuous development of technology, under the same ampacity, withstand voltage level, etc., the outer diameter of the cable is required to be smaller and smaller, and the raw materials consumed must be continuously reduced. This will not only adapt to carbon, sustainable The needs of development, and it brings new tasks to the mold design and production of cable processing; the cables in the prior art are made of circular insulated core wires and then multiple insulated core wires are twisted to form a cable core. Then it is extruded on the sheath extruder. This method makes the cable production process complicated, the number of processes increases, and the process takes a long time, resulting in untimely delivery and high manufacturing costs.

Abstract

The invention belongs to the technical field of electric wires and cables and particularly relates to a cable mold. The cable mold comprises a mold core and a mold cover and is characterized in that: the mold core consists of a forming part, a transition part and a connection part; the forming part is positioned at the front end of the mold core; the transition part is positioned at the middle end of the mold core; the connection part is positioned at the rear end of the mold core; the forming part consists of conductor guide devices, isolating bar forming channels and filling body guide devices; the quantity of the conductor guide devices is equal to that of the isolating bar forming channels; and the mold core has an integrated structure. The invention has the advantages that: the cablemold is convenient to mount and easy to manufacture, processes of producing the cables can be reduced, the cables have higher production speeds, the produced cables have smaller diameters, and the cable mold has lower material consumption and lower cost.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a cable mold. Background technique [0002] In the prior art, cables have been widely used, and there are various molds for producing cables, but the technology has matured. However, with the continuous development of technology, under the same ampacity, withstand voltage level, etc., the outer diameter of the cable is required to be smaller and smaller, and the raw materials consumed must be continuously reduced. This will not only adapt to carbon, sustainable The needs of development, and it brings new tasks to the mold design and production of cable processing; the cables in the prior art are made of circular insulated core wires and then multiple insulated core wires are twisted to form a cable core. Then it is extruded on the sheath extruder. This method makes the cable manufacturing process complicated, the number of processes increases, and t...
