Example Embodiment

[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0023] An extrusion mold made by a cable wire includes an extrusion mold base 12, a cavity through left and right is provided in the mold base 12, and a vertical injection port is provided on the upper side. The injection port is connected to the extrusion mold through a connecting flange 121 Device connection. A male mold 7 and a female mold 14 are respectively provided on both sides of the cavity in the extrusion mold base 12, and a cavity is formed between the male mold 7 and the female mold 14. The female mold 14 is fixed on the right side of the mold base 12 by a lock nut 13. The inner surface of the female mold 14 is cone-shaped, and the bottom opening of the cone is placed horizontally, and a forming tube 15 is provided in the bottom opening.

[0024] The male mold 7 is connected to the mold body 4, and the mold body 4 is connected to the mold ...

Abstract

The invention relates to the electric wire and electric cable manufacture field, and particularly to a plastic extruding mould required by production of a concentric sparse winding shielding layer of a plurality of single-wire conductors under a cable sheath layer. Disclosed is the plastic extruding mould for producing electric cables. The plastic extruding mould includes a plastic extruding mould base; a male mould and a female mould are respectively arranged at two sides of a cavity in the plastic extruding mould base, a mould cavity is formed between the male mould and the female mould, the female mould is connected with a forming pipe, and the male mould is connected with a mould body; the interior of the mould body is connected with a stranding cage through bearings, the interior of the stranding cage is provided with a threading pipe, the stranding cage can rotate around the threading pipe, the right end of the stranding cage is provided with a distributing terminal board, and the distributing terminal board is provided with wire harness conduits. A wire core is passed through the threading pipe, then through the male mould and the female mould, next through the forming pipe, and is connected with a traction machine set; and sparse winding single wires are passed through the wire harness conduits and the distributing terminal board.

Description

technical field [0001] The invention relates to the field of manufacturing and processing of electric wires and cables, in particular to an extrusion mold required for the manufacture of a concentric sparsely wound shielding layer of multiple single-wire conductors under a cable sheath layer. Background technique [0002] With the rapid development of the wire and cable industry, wire and cable are not only a simple transmission medium, but also the quality of power transmission and environmentally friendly power supply are increasingly valued by the wire and cable manufacturing industry. Anti-interference cables, frequency conversion cables, low-radiation cables, etc., are born with shielded and isolated electromagnetic cables. Most wires and cables are suitable for the transmission of alternating current. Due to the change of power frequency, a large number of radiated electromagnetic fields are generated. These radiated electromagnetic fields permeate the environmental sp...
