Description

Technical Field

[0002] Flat cable or ribbon cable is a flat wire formed by combining many wires together. This cable is low-cost, light-weight, strong, and easy to use in large and small equipment. The conductor of the flat cable needs to be covered with an insulating layer during the production process. The plastic needs to be plasticized by a wire and cable extruder, and then the plasticized plastic is evenly extruded on the core of the flat cable through a mold;

[0003] Some existing flat cable processing molds are mostly fixed at the discharge port of the wire and cable extruder. The mold for fixing the wire is fixedly connected to the mold sleeve, leaving a material cavity in the middle as an extrusion flow channel for the plastic, and a shaping mold is opened at the front end of the mold sleeve;

[0004] There are some problems. The mold and the mold sleeve are fixed, and the extrusion pressure of the plastic cannot be quickly controlled. If the extrusion pressure of the plasticized plastic is too small, it is easy to cause the plastic to be glued and seamed poorly, and there is an obvious mark. When the pressure is too large, the amount of plastic extruded is small, and the insulation layer is thin and leakage is likely to occur. Adjusting the extrusion pressure of the plastic requires stopping the machine to replace the mold sleeve and the mold, which affects production efficiency. For this reason, we propose a mold for flat cable processing. Utility Model Content
