Description
Technical field
The present invention relates to a kind of and extrusion head phase configuration for optical cable shaping from centering adjustable mold.
Background technology
The outer surface of optical cable need the floor height molecule oversheath of extrusion molding one so that cable core from external force, ultraviolet, aqueous vapor shadow
Ring, oversheath is extruded by extruding machine and is coated on cable core.The shape of oversheath is mostly annular, but there is also flat cable
With the special-shaped oversheath optical cable such as 8 word self supporting cables.The oversheath shaping dies of existing extruder head generally comprises core rod and mould
The hollow space of cover, wherein core rod passes through cable core, is filled by sheath material between the periphery of core rod and the inwall of die cap, mould
The outlet shapes of lid determine the profile of cable.In the production of cable jacket, concentric alignment must be kept between core rod and die cap, and it is different
Concentricity and the depth of parallelism requirement of type cable are more accurate, and traditional manual adjustment is difficult to accomplish accurate, it is difficult to ensure the matter of sheath
Amount, and cause production efficiency to decline.Some conventional are exempted to adjust concentric mould program（Such as CN205326231U）Can meet certain
Technical requirements, but structure is complex, and reality processing is difficult, relatively costly.
The content of the invention
The technical problems to be solved by the invention are that the deficiency existed for above-mentioned prior art provides one kind for light
Cable shaping from centering adjustable mold, its not only structure setting advantages of simple installs easy to adjust, and core rod die cap centering essence
Close height, crudy is good.
The present invention is to solve the problems, such as that used technical scheme set forth above is：Core rod and die cap are included, its feature
Be that described die cap includes outer die casing and is installed in the template of outer die casing inner chamber front end, described core rod include core rod body and
The adjustable cable core passage of core rod chamber body front end is passed, core rod body leading portion enters outer die casing inner chamber, and pacifies by front end face
If support locating dowel be connected with the rear end face of template, the front end of described adjustable cable core passage and the middle part nib phase of template
Configuration.
By such scheme, described core rod body includes the coupling part of the support platform and rear portion of front portion, flat in support
The connection changeover portion of taper type is set between platform and coupling part, and postmedian opens up cavity, front portion correspondence support in core rod body
Platform opens up the through hole for installing adjustable cable core passage, and through hole makes insertion before and after core rod chamber body with cavity.
By such scheme, before described adjustable cable core passage includes cable core poling, cable core poling and through hole phase configuration and energy
After move, and fixed by the holding screw being installed in laterally through support platform.
By such scheme, described cable core poling front end periphery is tapered, and angle of taper is 0 ~ 10 °
By such scheme, described outer die casing inner chamber is in truncated cone-shaped, pre-small post-large, and front end sets backstop end face, described template
It is the backstop end face phase configuration of tabular, front end face and outer die casing, rear end face sets positioning jack and support locating dowel front end phase
Grafting, template middle part opens up the front end phase configuration of nib and adjustable cable core passage.
By such scheme, described nib is circular, pancake or 8-shaped, or other odd-shaped cross sections, the outer shield with optical cable
Set shape of cross section is identical.
By such scheme, the unilateral tilt angles of described truncated cone-shaped outer die casing inner chamber are 10 ~ 25 °.
By such scheme, described support locating dowel sets 2 ~ 4, supports rear end and the core rod body portion of locating dowel
Support platform is mutually connected firmly.
The beneficial effects of the present invention are：1st, die cap is divided into outer die casing and template two parts, simplifies structure, reduced
The difficulty of mould processing, has saved material, reduces cost, while easy to disassemble and cleaning；2nd, template and outer die casing are separated, mould
Plate is connected by supporting locating dowel with core rod, is easy to the centering of nib and core rod to position, and the centering of core rod die cap is accurate high, processes matter
Measure, without being influenceed by extruding machine installation accuracy；I.e. assembling is completed this mould before upper head, and concentric centering passes through machine
Tool machining accuracy ensures, while improving precision, reduces the time and labor adjusted on head；3rd, by exchanging template i.e.
Can be used to process the optical cable of different cross section shape, be capable of achieving one module multiple usages；The 4th, adjustable cable core passage is set, by adjustable tubular conduit
Assembled with core rod mating holes, the length for stretching out core rod platform is adjusted according to the state to sheath cladding cable core, and loose tube structure is then
The end face for stretching place part is concordant with cover plate outer face, and then extension is short in cover plate inner face for tight tube structure.So that same cover die
Using in the shaping of the cable of different technologies requirement, one module multiple usages reduce production cost to tool.
