The application be the applying date on 05 26th, 2014, it is entitled：A kind of mould for manufacturing cable air-blowing pipeline
Tool component, Application No.：201410224423.1 patent of invention divisional application.
Technical field
The invention belongs to mould and pipe technology field, more particularly, to a kind of mould for manufacturing cable air-blowing pipeline
Tool component.
Background technology
With developing rapidly for the industries such as electric power, communication, the amount of laying of cable is more and more, on the one hand, due to big in the past
The cable of amount is laid using built on stilts, therefore, aerial cable is very in disorder, have impact on city look and feel, meanwhile, bring greatly
Potential safety hazard；For this purpose, country has promulgated corresponding law, regulation and instruction, need for cable using enter by the way of carry out
Lay.Cable mainly has poling and direct-buried mode in underground laying, and direct-buried mode needs to dig ground, and needs multiple tracks to examine
Formality, therefore, it is cumbersome；For this purpose, pipeline laying mode would is that after underground laying principal mode.
In the larger caliber pipeline that underground has been laid, less for diameter and smooth in appearance cable, in pipeline
In can directly carry out drawing when having sufficient space and lay, but, pull cable laying operation progress relatively slow and easily affect cable
Quality, especially optical cable, once the quality of cable is damaged in construction, cable is taken out or the cost of restorability are just very huge
Greatly.
For larger city, existing cable pipeline resource pretty nervous generally rent 1KM about 18mm diameters
Pipeline, annual price at 200,000 yuan or so, therefore, it is fairly expensive；Nonetheless, the operator in also many areas and non-fortune
Battalion business affects the progress of engineering less than conduit resource because renting, in addition have can only abandon original engineering.
For this purpose, expecting that there is preferable solution in industry, there can be the pipeline of excess room in underground；And production gas

Any one described above is used for manufacturing the die assembly of cable air-blowing pipeline, it is characterised in that all core rods
The outward flange of convex body is on the side of same cylinder；The cable that this structure is produced is with air-blowing pipeline is symmetrical, structure
Be not in weight inequality in stable, construction and produce free rolling phenomenon.
The principle of the present invention is such：When cable is manufactured with air-blowing pipeline, core rod is arranged on by core rod union joint
On the head of extrusion molding machine, die cap is fixedly mounted on the head of extrusion molding machine by one end of die cap body, and die cap is located at
Outside core rod, core rod is located at die cap intracavity, and the plunger union joint of plunger body is fixed in the core rod connecting hole of core rod, plunger body
A part for plunger is located in mold core cavities, and the end face of mold core cavities, core rod convex body and die cap are stretched out in the one end of plunger body without plunger
Cavity wall is discontiguous, the end face of the end face of the other end of the column of mold core cavities without departing from the other end of die cap；Extruding machine
Device is outputed, and melts air-blowing pipeline material material, and the material of thawing is continuously injected into injecting hole, and enters into die cap intracavity, and notes
Full die cap chamber, due to injection hole pressure it is larger, therefore, the material of thawing can only overflow from die cap chamber, due to the one end in die cap chamber
Be fixed on extrusion molding machine and close envelope, therefore can only overflow in die cap chamber another port, due to another port temperature it is relatively low,
Typically through air cooling and water cooling, crystallize rapidly after cooling, so cable air-blowing pipeline, shape are defined by traction
Into air-blowing pipeline there is air-blowing tube body, there is air-blowing pipe convex body and air-blowing pipe guiding gutter, middle shape on air-blowing tube body
Into there is air-blowing tube passage.
Certainly, when there is die cap groove on the inwall of die cap, there is projecting member, further on the air-blowing pipeline of formation
When forming compound air-blowing pipeline, during extrusion molding, projecting member is embedded in air-blowing pipe outer tube body, so makes the ectonexine of air-blowing pipe
Firmly, integral structure is more likely formed, in this case with reference to more, it is not necessary to which viscous gelatin substance in addition is by air-blowing pipeline and gas
Blowpipe outer tube body is bondd；During without projecting member, using bonding mode structure can be made more stable, in construction, coiling
When two-layer without departing from, construction when will not produce extra air-blowing resistance.
Plunger body is cylindrical shape, and the plunger union joint of plunger body is fixed on the core rod connecting hole of core rod, thereby it is ensured that
The formation of the air-blowing tube passage of air-blowing pipeline；In addition, the end face of mold core cavities is stretched out in the one end of plunger body without plunger, due in system
When making, the head of extrusion molding machine has a segment distance to the spacing of bosh, therefore squeezing for pull-tube type is defined during actual production
Mode processed, namely the overall dimensions of the air-blowing pipeline at bosh are than smaller at the head of extrusion molding machine, so so that gas
There is air-blowing pipe convex body and air-blowing pipe guiding gutter on the air-blowing tube body in blowpipe road, and the air-blowing pipeline for being formed is desired
Shape；When core rod convex body and core rod groove are spaced and lower section is continuous core rod inner wall, the cable for being formed
Just can be with relatively thick with the wall of the air-blowing tube body of air-blowing pipeline.
Certainly, the present invention when in use, can adopt completely the technology of closure, and part core rod groove or whole core rods is recessed
Groove is blocked, and so, when the cable of same size is produced with air-blowing pipeline, can selectively control the number of core rod groove
Amount.
Carry out laying test using the air-blowing pipeline of embodiment 5, ectonexine is all high-density polyethylene material, repeatedly around
Put 238 times, there are no the segregation phenomenon of air-blowing pipe outer tube body and interior tube body, and the inner tube and outer tube that could be used without projecting member are done
Into air-blowing pipeline, the inner and outer pipes lamination for having occurred as soon as many places for 3 times is laid repeatedly；During production, in being carried out using viscose glue
After outer tube bonding, equally carry out laying test, also only withstood the test of 12 times, when the 13rd time layering has been occurred as soon as；To upper
Three samples are stated, each sample is 800 meters, in each random 10 sections of the air-blowing pipeline for intercepting 1.5 meters long of length direction, air-blowing pipe
Road external diameter is 24mm, carries out ± 180 degree, bears a heavy burden for 150N, the test that speed is 10 beats/min, 10 samples of embodiment 5
Product, the torsion through 30 minutes has no cracking and lamination；And it is not glued, occurring as soon as layering after 6 times are reversed
Phenomenon；Bonding, occurring in that lamination after 38 times；Therefore, the air-blowing pipeline of the Making mold of embodiment 5 has
More excellent resistance to torsion, folding quality.
The present invention has following main beneficial effect：Mould structure is simple, easily make, it is wear-resisting, easily use；The air-blowing of manufacture
Pipeline quality is stable, reliable, resistance to torsion.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that the design of the present invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
