The invention discloses a copper-plastic co-extrusion sliding contact wire extrusion mold, and relates to the field of processing molds. The mold comprises a mold body, a driving box, a storage box and a discharging port, wherein the middle of the driving box is provided with a telescopic groove, the bottom of the telescopic groove is movably connected with a gear, the middle of the telescopic groove is movably connected with a telescopic plate, the lower surface of one end of the telescopic plate is fixedly connected with a rack, the other end of the telescopic plate penetrates through the telescopic groove and is fixedly connected with a supporting plate, one side of the supporting plate is fixedly connected with a plurality of connecting plates, and one ends of the connecting plates arefixedly connected with a push plate. According to the mold, the storage box can store the plastic fluid of a sliding contact wire, the discharging port is controlled to be opened and closed through avalve, the fluid enters the interior of the mold through the top of one end of the mold, the two ends of the interior of the mold can be sealed through the matching arrangement of a first insertion plate and a second insertion plate, and the plastic outer sleeve of the sliding contact wire is convenient to machine and form.
Description
Technical field [0001] The invention relates to the field of processing molds, in particular to a copper-plastic co-extrusion sliding contact line extrusion mold. Background technique [0002] Trolley wire, also known as sliding wire, is a group of power transmission devices that supply power to mobile equipment. It is mainly divided into monopolar aluminum conductor wire, unipolar copper conductor wire, steel body conductor wire, and multi-pole tubular conductor wire. Commonly used trolley wires such as wire, seamless trolley wire and copper contact wire, monopole trolley wire, multi-pole trolley wire, and seamless trolley wire belong to safety trolley wire, steel body trolley wire It is a non-safe sliding contact line. [0003] When the trolley wire in the prior art is produced, the trolley wire jacket is used to provide a protective effect on the trolley wire, but the trolley wire jacket in the prior art is mostly manually poured into the processing Inside the mold, there is a...
