Abstract
The utility model discloses an improved structure of the head of a wire and cable extrusion machine, which comprises an inner die head, an outer die head and a die, wherein the inner die head is provided with a middle through hole for guiding a metal wire; the outer die head is in coaxial butt joint with the inner die head, a passageway for insulating materials is formed between the outer die head and the inner die head, the outer die head is provided with a wire-penetration hole, and the wire-penetration hole is butt joint with the middle through hole and intersects with the passageway; and the die is installed at the inner part of the outer die head, the wire-penetration hole penetrates through the die, and the outer side of the outlet of the die is provided with a polytetrafluoroethylene coating. Therefore, with the characteristics of the polytetrafluoroethylene that the surface energy is small, the surface tension is low and the extruded fused material is difficult to adhere to the surface of the die, the problem of 'pits' formed by the accumulation of insulating materials at the local surface of opening of the die when forming the insulating layer of the metal wire is avoided, so that the surface of the insulating layer of the extruded and formed wire and cable is very smooth, thereby realizing the normalization and the standardization of wires and cables, improving the quality of a product, and enhancing the market competitiveness.
Description
Technical field
The utility model relates to the extrusion field of mechanical technique, refers in particular to a kind of structure-improved of electric wire extruder head.
Background technology
Processing equipment as thermoplastic shaping, nowadays extruder has been applied in the manufacture field of electric wire widely, the effect of extruder is mainly used to the liquid insulating material coated metal lead of fusion is formed insulating barrier, thereby produces life and the needed electric wire of commercial Application.The extruder most important parts is the head position, die head and outer die head in head mainly comprises, head inside has for the runner of the liquid insulating material extruding circulation of fusion and the middle through hole that the guiding plain conductor moves, make liquid insulating material closely wrap plain conductor by interior die head and the cooperation of outer die head, and extrusion and tractive formation electric wire.Yet, owing to be difficult to reach idealized effect during liquid insulating material coated metal lead, the problem that the minor insulation material is piled up unavoidably can appear, therefore, occur some graininess projectioies easily on the surface of insulating layer of the electric wire of the extruder head extrusion of generally adopting at present, be commonly called as " gum " or " pit ", cause the electric wire bad order, do not meet industrial normalization, standardization, be unfavorable for market competition.
The utility model content
The purpose of this utility model provides a kind of structure-improved of electric wire extruder head, solve the problem that the graininess projection appears in above-mentioned electric wire surface of commonly using the head extrusion, realize normalization, the standardization of electric wire, improve the quality of products, enhance one's market competitiveness.
The utility model adopts following technical scheme for achieving the above object:
A kind of structure-improved of electric wire extruder head comprises interior die head, outer die head and eye mould, described in die head be provided with a through hole that is used for guiding plain conductor; Described outer die head and interior die head are coaxial docking, and form the runner of insulating material therebetween, and this outer die head is provided with a cable-through hole, and this cable-through hole docks with the middle through hole of described interior die head and be crossing with the runner of insulating material; Described eye mould is installed on outer die head inside, and cable-through hole passes this mould, and the eye mould outlet outside is provided with polytetrafluorethylecoatings coatings.
The utility model compared with prior art has tangible beneficial effect, it mainly is by exporting the arranged outside polytetrafluorethylecoatings coatings in the eye mould, utilize the material that the ptfe surface energy is little, surface tension is low, melt extrude to be difficult for adhering to its surperficial characteristics, avoided on eye die orifice surface, occurring in the plain conductor insulating barrier forming process problem that the minor insulation material is piled up, the surface of insulating layer of the electric wire of extrusion molding is very smooth, normalization, the standardization of electric wire have been realized, improve product quality, strengthened the market competitiveness.

Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
See also Fig. 1 and Fig. 2, a kind of structure-improved of electric wire extruder head, die head 10, outer die head 20 and eye mould 30 in comprising, wherein:
Die head 10 is provided with through hole 11 in described, passes for plain conductor; Described outer die head 20 is coaxial docking with this interior die head 10, form the runner 40 of liquid insulating material therebetween, should be provided with a cable-through hole 21 by outer die head 20, this cable-through hole 21 docks with the middle through hole 11 of described interior die head 10 and intersects with above-mentioned runner 40, described eye mould 30 is installed on outer die head 20 inside, cable-through hole 21 passes this mould 30, and the eye mould 30 outlet outside is provided with polytetrafluorethylecoatings coatings 31, prevents to form the graininess projection on the surface of insulating layer of the electric wire of extrusion molding.
Liquid insulating material flows into runner 40, when plain conductor through hole 11 from interior die head 10 is walked cable-through hole 21 to outer die head 20, just wrapped up by liquid insulating material, subsequently from eye mould 30 outlet extrusion moldings, realize plain conductor outsourcing insulating material, obtain life and the needed electric wire of commercial Application, owing to be provided with polytetrafluorethylecoatings coatings 31 in the eye mould 30 outlet outsides, utilize the ptfe surface energy little, surface tension is low, the material that melt extrudes is difficult for adhering to its surperficial characteristics, avoided on eye die orifice surface, occurring in the plain conductor insulating barrier forming process problem that the minor insulation material is piled up, the surface of insulating layer of the electric wire of extrusion molding is very smooth, has improved product quality.
Design focal point of the present utility model is: by exporting the arranged outside polytetrafluorethylecoatings coatings in the eye mould, utilize the material that the ptfe surface energy is little, surface tension is low, melt extrude to be difficult for adhering to its surperficial characteristics, avoided when the moulding of plain conductor insulating barrier, occurring the problem that the minor insulation material is piled up, the surface of insulating layer of the electric wire of extrusion molding is very smooth, normalization, the standardization of electric wire have been realized, improve product quality, strengthened the market competitiveness.
The above, it only is the utility model preferred embodiment, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
