Description

The co-extruder head prepared for electric wire

Technical field

The utility model relates to a kind of co-extruder head prepared for electric wire, belong to cable technology of preparing Field.

Background technology

Electric wire used at present is mostly the combined type insulation system using double-deck and the above, and extrusion way is general For 1+1 or double-layer coextrusion；The extrusion die of wherein described co-extruder head is mainly squash type.Due to existing two-layer compound Formula insulated wire cable needs at least inside and outside two layers of insulation and mutually combines closely；The extrusion method of 1+1 is first to extrude interior insulation, Then external insulation is extruded again, and such extrusion way can be such that double hyer insulation is influenced with reference to that not close and there may be impurity to mix The performance of cable insulation；Therefore insulating materials is extruded as more by the country in the form of using double-layer coextrusion now；But existing bilayer Co-extruding machine head structure is relative complex, and production effect is poor, of high cost, thus is subject to certain resistance in popularization and application.

The content of the invention

The purpose of the utility model is to overcome the shortcomings of the prior art, and offer is a kind of simple in structure, uses behaviour Facilitate, low manufacture cost, composite effect is good, the high co-extruder head for being used for electric wire and preparing of work efficiency.

To achieve the above object, the utility model adopts the following technical solution：A kind of bilayer prepared for electric wire Co-extruding machine head, including headstock, inner mould core, internal model core print seat, die sleeve, die sleeve seat, be equipped with above the headstock outer layer glue into Material mouth and hose lining feed inlet；Inner mould core with conical nose is connected by being fixed with the internal model core print seat in headstock Connect and be placed in the discharge port end of headstock, and be provided with the inside of the headstock of the discharge port end and be in same with inner mould core Die sleeve on one center line；And make between die sleeve and inner mould core formed with tilting, the front and rear endodermis passage being adjacently positioned and Exodermis passage, and double-layer coextrusion outlet shaping mould is formed, wherein the endodermis passage is connected with the hose lining feed inlet, Exodermis passage is connected with the outer layer glue feed inlet.

As preferred：The inner mould core tapered end portion conductor outlet is recessed in the disposed inboard of die sleeve endoporus, between the two The adjacent sprue of endodermis passage and the sprue of exodermis passage, the inner mould core are made up of a taper spacer respectively Seat is adjustably screwed in the headstock that is similarly tubulose in for tubulose and by screw thread；The die sleeve also by screw thread adjustably It is screwed in the endoporus of headstock discharge port end or is gone out by die sleeve seat installed in headstock in the endoporus of die orifice end.

The utility model has simple in structure, and use is easy to operate, low manufacture cost, and composite effect is good, and work efficiency is high The features such as.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model.

Embodiment

The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1, a kind of use described in the utility model It is described in co-extruder head prepared by electric wire, including headstock 1, inner mould core 2, internal model core print seat 3, die sleeve 4, die sleeve seat 5 The top of headstock 1 be equipped with outer layer glue feed inlet 6 and hose lining feed inlet 7；Inner mould core 2 with conical nose by with peace What the internal model core print seat in headstock 1 was fixedly connected and was placed in headstock 1 goes out die orifice end, and in the discharge port end The inner side of headstock 1 is provided with the die sleeve 4 being in the same center line with inner mould core；And make between die sleeve 4 and inner mould core 2 formed with Tilting, the front and rear endodermis passage and exodermis passage being adjacently positioned, and double-layer coextrusion outlet shaping mould is formed, wherein described Endodermis passage is connected with the hose lining feed inlet 7, and exodermis passage is connected with the outer layer glue feed inlet 6.

Shown in figure, the 2 tapered end portion conductor outlet of inner mould core is recessed in the disposed inboard of 4 endoporus of die sleeve, both it Between the sprue 9 of adjacent endodermis passage and the sprue 10 of exodermis passage are made up of a taper spacer 8 respectively, it is described Internal model core print seat 3 is tubulose and is adjustably screwed in by screw thread in the headstock 1 for being similarly tubulose；The die sleeve 4 also by Screw thread is adjustably screwed in headstock 1 and goes out in the endoporus of 12 end of die orifice or go out die orifice 11 by die sleeve seat 5 installed in headstock In the endoporus of end.

The course of work of the utility model is：First with ready conductor by drawing machine travel and penetrating internal model core print seat 3rd, stretched out from the die orifice 11 that goes out of inner mould core side；Then internal layer sizing material is sent in hose lining feed inlet 7 by an extruding machine, Outer layer sizing material is sent in outer layer glue feed inlet 6 also by another extruding machine at the same time, this is in the case where the stove of extruding machine does rotation, is divided Endodermis passage and exodermis passage and the endodermis passage that goes directly continuously uniformly are sent into not by two kinds of different sizing materials The sprue 10 of sprue 9 and exodermis passage, since the sprue 9 of endodermis passage and the sprue 10 of exodermis passage are Successively arrange in tandem, therefore, both extrusion molding recombination processes successively carry out, and one layer of hose lining are initially formed, then in internal layer One layer of outer layer glue is formed outside glue at once, double insulating layer is formed and is extruded on conductor outer layer face, as conductor passes through a constant speed The movement of degree, its outer layer surface will it is continuously compound on hose lining and outer layer glue.
