Description
Technical field
The present invention relates to a kind of composition structure of rubber and plastic extrusion equipment and its manufacture method, more specifically, it relates to one
Kind cable jacket cross-head system and its manufacture method.
Background technology
The lasting propulsion of " broadband China " strategy is benefited from, policy driving operator networking dynamics of investment increases, " a band one
Road " implementation, and digital the Silk Road accelerate the appearance of policy of going to sea, and communications optical cable sheath product demand is with about 20% or so
Year amplification continue the situation of steady-state growth.Oversheath as last procedure of communications optical cable sheath production was molded
Essential process equipment is cross-head system in journey, and every extruder is equipped with 1 set or 2 sets or even covers head more
System, structure type also tend to variation, each communications optical cable sheath manufacturing enterprise in daily production and living increasingly from
Outstanding head system is not opened and brings convenient, and this convenience also makes competition turn into each one big power of enterprise；Enterprise is all opening
Hair or Entrust research dismounting is more convenient, adjustment time is less or without adjustment, be molded more stable extruder head system and
Matching die；This is also related to that manufacturer realizes and makes a profit and the competitiveness in market, thus when turning into practitioner's innovation urgently
The factor that need to be considered；Conventional cable jacket oversheath cross-head system and the structure of mould mainly include a head sheet
Body, a temperature control package assembly, a mixing flow-guiding structure body, external mold installation positioning chamber, an internal model plug, are equipped with necessary
Internal model and external mold, the head system of this structure have that head is bigger, power consumption is high, mould is relatively large in head, optical cable shield
Cover oversheath shaping and rely on minimum 4 set screws, and the defects of regulation, operation inconvenience etc..Publication No.
CN104494100B invention disclosed a kind of extruder head on 2 15th, 2017, including external mold, mouth mold, core, plug,
Connecting cylinder and mesh plate.External mold is provided with open cavity.Core is contained in open cavity, formed with melting material between core and external mold
Runner.Mesh plate is fixed between the inwall of connecting cylinder.Core one end is fixedly connected with mesh plate, and the core other end is consolidated with plug
Fixed connection.Core one end of extruder head of the present invention is directly fixedly connected with mesh plate, and the core other end is fixedly connected with plug,
Compared with the prior art that spreader is fixed on external mold by some brace rods, do not have in the melting material runner between core and external mold
There is brace rod, this is avoided that melting material in extrusion, and melting material is uneven and caused by shows because of the stop of brace rod by during melting material runner
As being not in cause extruding pipe material to produce line trace phenomenon because melting material is uneven, will not cause to be easy to showing for cracking because of line trace
As, therefore the tubing of extruder head of the present invention extrusion does not have line trace, apparent good and not easy to crack.But the invention is also and prior art
Plug is equally provided with, adds structural complexity and assembling, the difficulty of regulation.
The content of the invention
In the prior art, when cable jacket oversheath is extruded, because structure is relative complex, head is bigger than normal, easily tears open
The problems such as ETL estimated time of loading is long, sheath is molded and eccentricity control depends on the real-time regulation in production operation, to overcome these defects, this
Invention provides that a kind of energy consumption is low, structure is relatively easy, the cable jacket cross-head system of mold forming easy to loading and unloading, integral
System.
The technical scheme is that：A kind of cable jacket cross-head system, including head leading portion, head stage casing and
Head back segment, head back segment are provided with die cavity, are provided with deflector and die holder in die cavity, this cable jacket cross-head system is also
Including discrete Integral mold, discrete Integral mold includes preceding mould and rear mold, preceding mould and rear mold be rotary body and be coaxially disposed in
In the discrete Integral mold installation cavity of deflector and die holder, preceding mould and rear mold are bonded with discrete Integral mold installation cavity wall,
Preceding mould center is provided with formed product chamber, and the front and rear mould spacer of annular is provided between preceding mould, rear mold.Preceding mould, rear mold are led in the present invention
Crossing the constraint of discrete Integral mold installation cavity can ensure to install axiality, and front and rear mould spacer makes to keep certain between preceding mould, rear mold
Interval, forms uniform annular sizing material circulation road, sizing material can from all directions uniformly, be rapidly introduced into formed product chamber.This is discrete
Formula Integral mold ensures to assemble axiality without the plug in routine techniques, carried without the fan-shaped conduit by being opened on plug
For axial sizing material circulation road, therefore it can not only simplify structure, plastics are thick when can also effectively strengthen cable jacket product extrusion
The uniformity of degree.Front and rear mould spacer width can be arranged as required to, and can be increased and decreased when sizing material is extruded according to the width of spacer and adjusted
Make the internal pressure of extruder and head, make sizing material extrusion stable, uniform by adjusting pressure.
Preferably, deflector and die holder one end are provided with stationary gland, the discrete Integral mold is located at deflector
And in the region that encloses of die holder and stationary gland, preceding one end face of mould abuts with the inner face of stationary gland.Stationary gland
, can be right after discrete Integral mold loads discrete Integral mold installation cavity for closing the openend of discrete Integral mold installation cavity
