Abstract

The utility model discloses a flat cable sheath extrusion die, comprising a die sleeve, and a die core, wherein inside the die sleeve there is provided a through channel, the outlet of the channel is processed into a bell mouth, inside the bell mouth there is provided a die core matched with the bell mouth therein, inside the die core there is provided a through hole matched with the outer wall of the flat cable sheath, the outer wall of the extended segment of the die core located outside the bell mouth is provided with a circle of annular projection, the end portion of the bell mouth of the die sleeve is fixedly provided with a grading ring, and the grading ring is invertedly fastened on the projection for circumferentially fixing the die core. The flat cable sheath extrusion die is easy in flat die mouth alignment, good in coaxiality, and convenient in operation and production processing, and increases productivity, the design of the die core can enable the glue output amount and the extrusion pressure at various positions of the die mouth to be equal, and the design of the bell mouth prolongs the moulding press time in order to inhibit the middle rising force, thereby avoiding the phenomenon that the flat shape is not flat, and ensuring profile size.

Description

A kind of flat cable sheath extrusion die

Technical field

The utility model relates to flat cable and makes the field, relates in particular to a kind of flat cable sheath extrusion die.

Background technology

Along with the development of industries such as China's port and pier, power plant, steel mill, mine and petrochemical industry, introduced a large amount of comprehensive mechanical equipment, its power supply adopts collection power, communication mostly, is controlled in the flat type cable of the various specific (special) requirements of one.

Flat type sheath soft cable is to be used for moving frequently, needs the occasion of crooked towing, when making the flat cable sheath; If mold design is improper, it is not bright and clean that the surface appears in regular meeting, and sheath is eccentric; Became uneven is even, construction of cable unstable properties, quality problems such as insulation and sheath exit.

Therefore need a kind of flat cable sheath of design to use extrusion die, with the deficiency that addresses the above problem.

The utility model content

To the prior art problem, the purpose of the utility model provides a kind of flat cable sheath extrusion die, and reasonable in design can realize that cables manufacturing is easy to process, stable performance, compact conformation.

The technical scheme of the utility model is following:

Flat cable sheath extrusion die comprises die sleeve, core rod, it is characterized in that: have the runner that runs through in the described die sleeve; The export processing of runner becomes the horn mouth of flat; Be set with core rod with matching in the horn mouth, have the through hole that matches with flat sheath outer wall in the core rod, be positioned at the convexity that the outer core rod section of the stretching out outer wall of described horn mouth is provided with a circle annular; Described die sleeve flare end is fixed with grading ring, and grading ring is fastened on circumferential fixed die core on the described convexity.

Described flat cable sheath extrusion die is characterized in that: described core rod and die sleeve adopt the stainless steel anti-corrosion material.

Compared with present technology, the utility model beneficial effect is embodied in:

1, the utility model mould, it is right that platypelloid type die orifice (horn mouth) is prone to, good concentricity, operation and production and processing are convenient, have improved productivity ratio;

2, the design of the utility model core rod can accomplish to make die orifice gel quantity and extrusion pressure everywhere all to equate.

3, the utility model die sleeve discharging opening is processed into horn-likely, and the time that prolongs its shaping pressurized solves the not flat phenomenon of flat type with tension in the middle of suppressing, and guarantees overall dimension;

4, the utility model can effectively be realized one module multiple usages, for enterprise saves production cost, has effectively prevented the phenomenon that materials flow is refunded simultaneously;

5, the utility model can efficiently solve the outlet efficient at exit seal place.

6, the flat cable of the utility model production, sheath is superior in quality, can realize the flat cable of specific (special) requirements, realizes the flat cable production domesticization, has filled up the blank of domestic like product;
