Description

Technical Field

[0001] The invention mainly relates to the technical field of cable processing, in particular to a cable anti-twisting wire manufacturing mould. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulation layers, and are used to connect circuits, electrical appliances, etc. In the process of cable processing, molds are needed to cool and shape the cables.

[0003] In the existing cable manufacturing molds today, for example, the technical structure of the application document with application number CN202121132274.8, it includes a mold base, and a molding cavity and a cooling cavity arranged in sequence in the mold base along the cable conveying direction. A feed pipe connected to the molding cavity and a discharge pipe connected to the cooling cavity are respectively provided on both sides of the mold base, and the molding cavity and the cooling cavity are connected through a corridor, and a cooling box is fixed on the upper end face of the mold base, and a circulating pump is installed in the cooling box. The circulating pump is connected to a cooling pipe, and the cooling pipe is evenly wound around the outer side of the cavity wall of the cooling cavity and then extends into the cooling box to form a circulating pipe. Two fixed plates are symmetrically fixed on the upper and lower sides of the port of the feed pipe, and a mounting shell is movably and liftably installed on the opposite side of the two fixed plates. Although the device realizes the processing and cooling molding of the cable, there is no anti-twisting component in the cooling and molding process, which easily causes the center line to twist, which increases the difficulty of the later wire winding and the wrapping of the insulating jacket, and reduces the work efficiency.

[0004] Based on this, we need to develop a cable anti-twisting wire manufacturing mold, so that during the cooling and molding process, the probability of twisting of the cable center line can be effectively reduced, and no manual positioning is required, which is very convenient and reduces the difficulty of winding the wire around the center line and wrapping the insulating jacket in the later stage.
