Described above any one be the die assembly with air-blowing pipeline for the manufacture of cable, it is characterized in that the outward flange of all core rod convex bodies is on same cylindrical side; For the cable that this structure produces, in air-blowing pipeline symmetry, Stability Analysis of Structures, construction, there will not be weight inequality and produce free rolling phenomenon.
Principle of the present invention is such: when manufacturing cable with air-blowing pipeline, core rod is arranged on the head of extrusion molding machine by core rod connector, die cap is fixedly mounted on the head of extrusion molding machine by one end of die cap body, and die cap is positioned at core rod outside, core rod is positioned at die cap chamber, the plunger connector of plunger body is fixed in the core rod connecting hole of core rod, a part for the plunger of plunger body is arranged in mold core cavities, plunger body stretches out the end face of mold core cavities without one end of plunger, core rod convex body and die cap cavity wall are discontiguous, the end face of the other end of the column of mold core cavities does not exceed the end face of the other end of die cap, extrusion molding machine is outputed, and air-blowing pipeline is melted with material, the material melting injects injecting hole continuously, and enter in die cap chamber, and fill with die cap chamber, because injection hole pressure is larger, therefore, the material melting can only overflow from die cap chamber, because the one end in die cap chamber is fixed on extrusion molding machine and closes envelope, therefore can only overflow in another port, die cap chamber, because another port temperature is lower, normally pass through the cooling and water cooling of air, cooling rear rapid crystallization, by traction, formed cable air-blowing pipeline like this, the air-blowing pipeline forming has air-blowing tube body, on air-blowing tube body, there is air-blowing pipe convex body and air-blowing pipe guiding gutter, centre is formed with air-blowing tube passage.
Certainly, while thering is die cap groove on the inwall of die cap, on the air-blowing pipeline forming, there is projecting member, when further forming compound air-blowing pipeline, during extrusion molding, projecting member is embedded in air-blowing pipe outer tube body, make like this ectonexine of air-blowing pipe in conjunction with more firm, more easily form integral structure, in this case, do not need other sticky gelatin substance that air-blowing pipeline and air-blowing pipe outer tube body are bondd; And while there is no projecting member, adopt bonding mode can make structure more stable, and two-layerly when construction, coiling do not depart from, when construction, can not produce extra air-blowing resistance.
Plunger body is cylindrical shape, and the plunger connector of plunger body is fixed on the core rod connecting hole of core rod, therefore, has guaranteed the formation of the air-blowing tube passage of air-blowing pipeline; In addition, plunger body stretches out the end face of mold core cavities without one end of plunger, due to during fabrication, the head of extrusion molding machine has a segment distance to distance between bosh, therefore having formed the mode that extrudes of pull-tube type during actual production, is also smaller than the head place of extrusion molding machine of the appearance and size of air-blowing pipeline at bosh place, like this, make to there is air-blowing pipe convex body and air-blowing pipe guiding gutter on the air-blowing tube body of air-blowing pipeline, and formed air-blowing pipeline is desired shape; When core rod convex body and core rod groove space and below are continuous core rod inner wall, formed cable just can be relatively thick with the wall of the air-blowing tube body of air-blowing pipeline.
Certainly, the present invention in use, can adopt the technology of shutoff completely, and part core rod groove or whole core rod groove are carried out to shutoff, like this, when the cable of producing same size is used air-blowing pipeline, can control selectively the quantity of core rod groove.
Adopt the air-blowing pipeline of embodiment 5 to lay test, ectonexine is all high-density polyethylene material, repeatedly around putting 238 times, segregation phenomenon there are no air-blowing pipe outer tube body and interior tube body, and adopt, there is no the inner tube of projecting member and the air-blowing pipeline that outer tube is made, repeatedly lay the inner and outer pipes lamination that has just occurred many places for 3 times; During production, when adopting viscose glue to carry out, after inner and outer pipes bonding, laying equally test, also only withstand the test of 12 times, in the time of the 13rd time, just occurred layering; To above-mentioned three samples, each sample is 800 meters, in 10 sections, the air-blowing pipeline of 1.5 meters long of each random interceptings of length direction, air-blowing outer diameter tube is 24mm, carrying out ± 180 degree, bearing a heavy burden for 150N, speed is the test of 10 beats/min, 10 samples of embodiment 5, have no cracking and lamination through the torsions of 30 minutes; And do not bond, after 6 times are reversed, just there is lamination; Bonding, after 38 times, there is lamination; Therefore, the air-blowing pipeline of the mould manufacture of embodiment 5 have better resistance toly turn round, folding quality.
The present invention has following main beneficial effect: simple, the easy making of mould structure, wear-resisting, easily use; Stable, reliable, resistance to the turning round of air-blowing pipeline quality of manufacturing.
The present invention is not limited to above-mentioned preferred forms, should be appreciated that design of the present invention can be by other various forms enforcement utilizations, and they drop in protection scope of the present invention equally.
