Abstract
The utility model relate to a dual-color extrusion mould for electrical wires and cables, which aims at solving the problem that when the traditional dual-color extrusion mould is used for producing dual-color cores, especially relatively large dual-color cores, the insulating core coverage area of the secondary color is less than 30 percent, which does not reach national standards. As the inner end of a feeding channel is changed into a channel with narrower upper part and wider lower part, the area of the surface of an insulating core covered by the secondary color is ensured to be more than 30 percent and dual-color electrical wires and cables meeting the national standards are extruded.
Description
Technical field:
The utility model relates to the electric wire extrusion die, the definite double-colored extrusion die of a kind of electric wire of saying so.
Background technology:
Regulation in GB 5023, the double-colored core of electric wire should meet wherein a kind of color and cover 30% of insulated wire cores surface at least, and is not more than 70%, and another kind of color then covers the insulated wire cores remainder.One of double-colored extrusion way of electric wire is to annotate the bar machine to add the unit form at present, annotates the bar machine and injects auxilliary colorant, and unit is extruded the mass-tone material.Mould is made up of core rod, die sleeve and feeder channel, but owing to annotated the restriction that the bar machine connects the feeder channel pore size of die sleeve, often when producing the different size core, auxilliary wrapping lid insulated wire cores surface can be less than 30%, when especially the core specification is big even less than 15%, do not reach the GB requirement.
Based on above reason, when there was the bigger double-colored core of double-colored core, the particularly specification extruded in present double-colored extrusion die, auxilliary wrapping lid insulated wire cores surface less than 30% did not reach the problem of national requirements.
Summary of the invention:
The utility model purpose is to overcome the problems referred to above that the double-colored extrusion die of traditional electric wire of the prior art exists, providing a kind of can guarantee when extruding double-colored insulated wire cores, wherein a kind of color covers 30% of insulated wire cores surface at least, and is not more than 70% the double-colored extrusion die of electric wire.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The double-colored extrusion die of a kind of electric wire comprises core rod and die sleeve, it is characterized in that: die sleeve radially has feeder channel, and described feeder channel the inner is up-narrow and down-wide horn-like.
Described feeder channel outer end is a cylindrical hole, and the centre is a cylindrical step, and the inner is the flat horn mouth.
The mass-tone material is extruded in the gap of described core rod and die sleeve, and feeder channel is extruded auxilliary colorant.
Described core rod is a circular cone structure.
Advantage of the present utility model is:
According to core external diameter size, can change feeder channel flat horn mouth size, thereby guarantee that the double-colored core of extruding reaches the GB requirement.

Fig. 2 looks generalized section for a die sleeve left side among Fig. 1
Fig. 3 faces generalized section for existing double-colored extrusion die
Fig. 4 looks generalized section for a die sleeve left side among Fig. 3
Be labeled as among the figure: 1, core rod 2, die sleeve 3, feeder channel 4, existing feeder channel
Embodiment:
The double-colored extrusion die of a kind of electric wire comprises core rod 1, die sleeve 2 and feeder channel 3, and core rod 1 is a circular cone structure, and cooperates assembling with die sleeve 2, and die sleeve 2 radially has a feeder channel 3.Feeder channel 3 outer ends are cylindrical hole, and there is cylindrical step the centre, and the inner is the flat horn mouth.Auxilliary colorant injects by feeder channel 3, and the mass-tone material is extruded by the gap of core rod 1 and die sleeve 2, and auxilliary colorant and mass-tone material converge the formation insulating barrier in the mould port.General auxilliary wrapping lid insulated wire cores surface is 30% to 50%, the angle that is to say core center and horn mouth two edges is 108 ° to 180 °, then can extrude specification and calculate the horn mouth width by trigonometric function according to difference, because the influence of extrusion pressure, but actual horn mouth width positive and negative deviation 1 is to 2mm.
The feeder channel 4 of existing double-colored extrusion die is because inner discharging opening is cylindrical, its width is limited by the diameter of feeder channel outer end cylindrical hole, extruding the core specification when big, even it is maximum that inner diameter reaches, in the time of promptly identical with the outer end diameter, the double-colored core of extruding also can't reach requirement.And the utility model feeder channel the inner is a bell mouth shape, and the bottom diameter is not limited by nose-circle cylindricality diameter, thereby can make the double-colored core of extruding reach requirement.
Embodiment 1: auxilliary wrapping lid insulated wire cores surface is 30%
The double-colored extrusion die of electric wire is made up of core rod 1 and die sleeve 2, and core rod 1 is that circular cone structure cooperates assembling with die sleeve 2, and die sleeve 2 radially has a feeder channel 3, and feeder channel 3 outer ends are cylindrical hole, and there is cylindrical step the centre, and the inner is the flat horn mouth; Conductor diameter is 10.0mm before known the extruding, insulation thickness is 1.4mm, then extruding back core external diameter is 12.8mm, it is 30% that auxilliary colorant covers the insulated wire cores surface, be that core center and horn mouth both sides angle are 108 °, calculating the horn mouth width by trigonometric function is 10.4mm, actual desirable 10.0mm.
Embodiment 2: auxilliary wrapping lid insulated wire cores surface is 50%
The double-colored extrusion die of electric wire is made up of core rod 1 and die sleeve 2, and core rod 1 is that circular cone structure cooperates assembling with die sleeve 2, and die sleeve 2 radially has a feeder channel 3, and feeder channel 3 outer ends are cylindrical hole, and there is cylindrical step the centre, and the inner is the flat horn mouth; Conductor diameter is 10.0mm before known the extruding, insulation thickness is 1.4mm, then extruding back core external diameter is 12.8mm, it is 50% that auxilliary colorant covers the insulated wire cores surface, be that core center and horn mouth both sides angle are 180 °, calculating the horn mouth width by trigonometric function is 12.8mm, actual desirable 12.0mm.
The utility model is not limited to above embodiment.
