Abstract
A kind of optical cable extrusion die of the present utility model, including internal model and external mold, be formed as stream passage between described internal model and external mold, internal model is interior formed with cable core passage, it is characterised in that, internal model extends at die orifice, it is stream profiled section at die orifice, this section is arranged to hollow die orifice, is a part for internal model, the inwall of hollow die orifice contacts with cable core, outer wall and stream channel contact.The beneficial effects of the utility model are：By being arranged to hollow structure at die orifice, hollow structure can reduce thermal conduction rate so that stream is no longer influenceed by the cable core of normal temperature state, it is bad to avoid plasticizing caused by heat scatters and disappears at the die orifice, the problem of forming disconnected glue, reduce waste product generation, while also improve production efficiency.
Description
Technical field
The utility model belongs to optical fiber cable production equipment technology, specifically belongs to a kind of optical cable extrusion die.
Background technology
With the continuous development of communications industry, the demand rapid growth of optical cable, the tubular molding tool used during optical cable is produced
It is widely applied, but existing tubular molding tool is when extruding halogen-free anti-flaming polyolefin protective cover material, it is normal because what is quickly walked
Temperature state core easily takes away the heat at die orifice so that stream is melted insufficient at die orifice, the risk of disconnected glue be present.
Utility model content
A kind of optical cable extrusion die provided by the utility model, scattered and disappeared with reaching the heat of stream at reduction die orifice,
Avoid the occurrence of disconnected glue problem.
A kind of optical cable extrusion die of the present utility model, including internal model and external mold, shape between described internal model and external mold
It is interior formed with cable core passage as stream passage, internal model, it is characterised in that internal model is stream at die orifice to extension at die orifice
Profiled section, this section are arranged to hollow die orifice, are a part for internal model, and the inwall of hollow die orifice contacts with cable core, outer wall and stream
Channel contact.
The beneficial effects of the utility model are：
By being arranged to hollow structure at die orifice, hollow structure can be reduced thermal conduction rate so that stream is no longer
Influenceed by the cable core of normal temperature state, it is bad to avoid plasticizing caused by heat scatters and disappears at the die orifice, the problem of forming disconnected glue, reduces
Waste product generation, while also improve production efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is part A enlarged drawing of the present utility model.
In figure, 1, internal model；2nd, external mold；3rd, hollow die orifice；4th, stream passage；5th, flange；6th, head, 7, cable core.
Embodiment
Referring to accompanying drawing：A kind of optical cable extrusion die of the present utility model, including internal model 1 and external mold 2, described internal model 1
Be formed as stream passage 4 between external mold 2, formed with the passage of cable core 7 in internal model 1, it is characterised in that internal model 1 is to prolonging at die orifice
Stretch, be stream profiled section at die orifice, this section is arranged to hollow die orifice, for a part for internal model 1, the inwall and cable of hollow die orifice
Core 7 contacts, and outer wall contacts with stream passage 4.Flange is set on mould, head 6 is connected with extruding machine, extruding machine extrusion
Stream flows to stream passage 4 by flange 5.
