Abstract

The utility model discloses an electric wire and cable strip injection mould, which comprises a mould core and a mould sleeve. The mould sleeve comprises a mould sleeve body and a top cover; a screw penetrates through the top cover and the front end face of the mould sleeve body to connect and fix the top cover and the front end face of the mould sleeve body; the mould sleeve body is conical; a conical mould sleeve hole is arranged on the rear end face of the mould sleeve body and radially reduced from the rear end of the mould sleeve to the front end of the mould sleeve; a mould sleeve bearing path communicated with the mould sleeve hole is positioned on the end face of the top cover; the lateral surface of the mould sleeve body is provided with a rubber injecting hole, a plastic rubber and at least three rubber outlets sequentially facing the inside of the mould sleeve body; the rubber injecting hole, the plastic rubber and the rubber outlets are communicated with each other; the rubber outlets are communicated with the mould sleeve bearing path; the front of the mould core is conical and placed in the mould sleeve hole; the rear end face of the mould core is provided with a mould core hole; and a mould core bearing path communicated with the mould core hole is positioned on the front end face of the mould core. The electric wire and cable strip injection mould is simple and reasonable in structure, reliable in operation and low in manufacturing cost, and can be widely used for production of various electric wires and cables.

Description

A kind of electric wire is annotated the bar mould

Technical field

The utility model relates to a kind of notes bar mould, and particularly a kind of electric wire is annotated the bar mould.

Background technology

The existing notes bar mould (promptly two bar mould) that is used for electric wire, generally be the plastics of the another kind of color of injection moulding on a kind of plastics, be confined to two injection mouldings of annotating bar, but because the plastics of the another kind of color of injection moulding on still not a kind of plastics of some customer requirement, and require to annotate the bar radical greater than two and adjacent between color different, two bar moulds can't satisfy this requirement, at above-mentioned shortcoming, are necessary to make improvement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the plastics of the another kind of color of injection moulding on a kind of rational in infrastructure, a kind of plastics that can realize electric wire, and can produce annotate the bar radical greater than two and adjacent between the electric wire of the different notes bar of color annotate the bar mould.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of electric wire is annotated the bar mould, comprise core rod and die sleeve, described die sleeve comprises die sleeve main body and caping, there is screw to pass caping and die sleeve body front end face is connected and fixed them, described die main body is conical, have a conical die sleeve hole at die sleeve body rear face, this die sleeve hole radially dwindles from the die sleeve rear end toward front end, be positioned at the caping end face have the die sleeve that communicates with the die sleeve hole hold the footpath, described die sleeve main body side faces the die sleeve body interior and has the hole for injecting glue that communicates successively, plastic cement runner and gum outlet, described gum outlet is at least three, and holding the footpath with die sleeve communicates, described core rod front portion is conical, and place in the die sleeve hole, this die core back end face has the core rod hole, be positioned at the die core front end face have the core rod that communicates with the core rod hole hold the footpath.

Wherein, described plastic cement runner is a C shape.

The beneficial effects of the utility model are: by with core rod, die sleeve is fixed on the extrusion head and annotates on the bar machine head, again conductor is correctly passed the footpath of holding of core rod and die sleeve, to extrusion or annotate the bar machine with suitable temperature, pressure, conditions such as tractive effort are carried out electric wire extrusion or are extruded operation, simultaneously plastic melt is passed through hole for injecting glue, the plastic cement runner, gum outlet carries out the conductor injection operation, can realize the plastics of the another kind of color of injection moulding on a kind of plastics of electric wire by structure of the present utility model, and annotate the bar radical greater than two, it is six, color between adjacent is different, this operates disposable finishing, it is simple and reasonable, reliable operation, cost of manufacture is low, can be widely used in the production of all kinds of electric wires.

Fig. 2 is the structural representation of die sleeve front end face in the utility model;

Fig. 3 is the structural representation of die sleeve body front end face in the utility model;

Fig. 4 is the electric wire structure chart that adopts mould of the present utility model to make.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3.A kind of electric wire is annotated the bar mould, comprise core rod 1 and die sleeve 2, it is characterized in that: described die sleeve 2 comprises die sleeve main body 3 and caping 4, having screw to pass caping 4 is connected and fixed them with die sleeve main body 3 front end faces, described die main body 3 is conical, have a conical die sleeve hole 31 at die sleeve main body 3 rear end faces, this die sleeve hole 31 radially dwindles from die sleeve 2 rear ends toward front end, be positioned at caping 4 end faces have the die sleeve that communicates with die sleeve hole 31 hold the footpath 5, described die sleeve main body 3 sides have the hole for injecting glue 6 that communicates successively towards die sleeve main body 3 inside, plastic cement runner 7 and gum outlet 8, described gum outlet 8 is at least three, and holding footpath 5 with die sleeve communicates, described core rod 1 front portion is conical, and place in the die sleeve hole 31, this core rod 1 rear end face has core rod hole 11, be positioned at core rod 1 front end face have the core rod that communicates with core rod hole 11 hold the footpath 12.

In the utility model, described plastic cement runner 7 is a C shape.

By with core rod 1, die sleeve 2 is fixed on the extrusion head and annotates on the bar machine head, the core rod that again conductor is correctly passed core rod 1 and die sleeve 2 holds footpath 12, die sleeve holds footpath 5, to extrusion or annotate the bar machine with suitable temperature, pressure, conditions such as tractive effort are carried out electric wire extrusion or are extruded operation, simultaneously plastic melt is passed through hole for injecting glue 6, plastic cement runner 7, gum outlet 8 carries out the conductor injection operation, with reference to Fig. 4, can realize the plastics 20 of the another kind of color of injection moulding on a kind of plastics 10 of electric wire by structure of the present utility model, and annotate the bar radical greater than two, it is six, color between adjacent is different, this operates disposable finishing, it is simple and reasonable, reliable operation, cost of manufacture is low, can be widely used in the production of all kinds of electric wires.
