Embodiment 1

[0017] Such as Figure 2 ~ Figure 4 As shown, a parallel wire extrusion auxiliary mold includes a conventional cable mold cover 2, an auxiliary mold core 3, a conventional cable mold core 5, and a threading hole 6. The inner cavity of the conventional cable mold cover 2 is covered with a conventional Cable mold core 5, an extrusion sheath 1 is also installed on the gap between the conventional cable mold core 5 and the conventional cable mold sleeve 2, the cavity of the conventional cable mold core 5 is a tapered hole, and the tapered hole An auxiliary mold core 3 is set inside, and a plurality of threading holes 6 parallel to each other are evenly opened on the auxiliary mold core 3 .

[0018] The tapered hole of the auxiliary mold core 3 corresponding to the inner cavity of the conventional cable mold core 5 is a cone and the apex of the cone is flattened into a circular surface.

[0019] The described threading hole 6 is used for threading the cable core 4 .

Abstract

The invention relates to a parallel wire extruding auxiliary mould which comprises an extruding protective jacket (1), a conventional cable mould sleeve (2) and a conventional cable mould core (5), wherein the conventional cable mould core (5) is sleeved on an inner cavity of the conventional cable mould sleeve (2), the extruding protective sleeve (1) is also arranged on a gap between the conventional cable mould core (5) and the conventional cable mould sleeve (2), the inner cavity of the conventional cable mould core (5) is a taper hole, an auxiliary mould core (3) is sleeved in the taper hole, and a plurality of mutually parallel thread holes (6) are uniformly formed in the auxiliary mould core (3). The parallel wire extruding auxiliary mould is simple in structure, easy to process and variable in material selection, and can meet the production demand on various kinds of flat protective jacket wires.

Description

technical field [0001] The invention belongs to the technical field of cable production devices, in particular to an auxiliary die for extrusion of parallel electric wires. Background technique [0002] The original mold for the production of flat sheathed wires is a flat exit extrusion die, and different product specifications require different sizes of molds, and must be dedicated to the mold. Moreover, the mold requires high precision in design and processing, and the mold preparation period is relatively long. However, when there are special specification requirements in urgent orders, such molds are difficult to adjust and cannot be shipped within the delivery period. [0003] To sum up the above reasons, through the analysis of the stretching characteristics of the rubber material when extruded by the extruded tube die, the extruded round tube can completely cover two or more insulated wire cores arranged in parallel by stretching. to meet the requirements of paralle...
