The specific embodiment
As shown in Figure 1 and Figure 2, hot runner telescopic injection moulding apparatus of the present invention is used for the injection machine of bilayer or multilayer die cavity is poured into hot-melt plastic, comprise that injection nozzle 1 is with nozzle 7 and be connected injection nozzle and the hot flow path of nozzle 2, described hot flow path 2 outer walls are evenly equipped with heater, and this heater can be the heating wire that is wrapped in hot flow path 2 outer walls.Described injection nozzle 1 is fixedly mounted on the solid plate 3 of injection machine, because described hot flow path 2 is more than 4 or 4, be connected in series successively by sealing rotatable device P and form, described sealing rotatable device P comprises the active joint A8 that is fixedly installed in last hot flow path end, the active joint B8 ' that is fixedly installed in a back hot flow path head end and the hold down gag that both are close to.Described active joint A8 can rotate relatively with active joint B8 ', and the face that both are close to is the surfaces of revolution.Offer passage 11 and passage 11 ' respectively in described active joint A8 and the active joint B8 ', last hot flow path is connected with a back hot flow path.The interface center that is connected of described passage 11 and passage 11 ' is on active joint A8 and the active joint B8 ' rotating shaft, so that active joint A8 is relative with active joint B8 ' when rotating, the interface that is connected of passage 11 and passage 11 ' can seepage.Because active joint A8 can rotate relatively with active joint B8 ', but so hot flow path 2 level under the effect of external force flexible, it is flexible along folding mould direction level to drive nozzle 7 simultaneously, therefore described nozzle 7 no longer is confined to be installed on the solid plate 3.When being used for the injection machine of double-deck die cavity, described nozzle 7 is selected double swivel nozzle for use, and nozzle 7 is installed between first moving platen 4 and second moving platen 5, can be arranged at the die cavity in solid plate 3 and first moving platen 4 and be arranged at second moving platen 5 and the 3rd moving platen 6 in die cavity injection moulding simultaneously.Because nozzle 7 two ends injection mouldings are to carry out synchronously, and pressure is also identical, therefore the problem of injection moulding inequality can not appear.When being used for the injection machine of multilayer die cavity, the nozzle 7 of respective numbers can be set, and will link to each other with injection nozzle 1 again after these nozzle 7 parallel connections, and it being flexible to make each nozzle 7 can both prolong folding mould direction level.Because each nozzle 7 injection moulding is carried out synchronously, and pressure is also identical, therefore the problem of injection moulding inequality also can not appear.
As shown in Figure 3, described hold down gag comprises the fixed frame 10 that is arranged at the active joint A8 and the active joint B8 ' outside, by fixed frame 10 surfaces of revolution of active joint A8 and active joint B8 ' is compressed, the described surfaces of revolution of active joint A8 and active joint B8 ' that makes can be the plane.
As shown in Figure 4, described hold down gag is except being arranged at the fixed frame 10 in active joint A8 and the active joint B8 ' outside, be equipped with at an end of fixed frame 10 or symmetrical two ends in addition with active joint A8 and active joint B8 ' offset and compress screw 12, this central shaft that compresses screw 12 overlaps with the rotating shaft of active joint A8 and active joint B8 '.Installation compresses the easier applying of the surfaces of revolution that screw 12 can make active joint A8 and active joint B8 ', owing to compress screw and active joint A8 or little with the contact-making surface of active joint B8 ', therefore rotates more laborsaving simultaneously.The surfaces of revolution of described active joint A8 is provided with shrinkage pool 13, the surfaces of revolution of described active joint B8 ' is provided with and shrinkage pool 13 corresponding boss 14, the rotating shaft coaxle of the central shaft of described shrinkage pool 13 and boss 14 and active joint A8 and active joint B8 ' can make the more difficult seepage that occurs of surfaces of revolution when active joint A8 is relative with active joint B8 ' to be rotated like this.
As shown in Figure 5, described hold down gag is except being arranged at the fixed frame 10 in active joint A8 and the active joint B8 ' outside, at an end or the symmetrical two ends of fixed frame 10 plane bearing 15 that offsets with active joint A8 and active joint B8 ' is installed in addition, the central shaft of this plane bearing 15 overlaps with the rotating shaft of active joint A8 and active joint B8 '.Mounting plane bearing 15 also can make active joint A8 or relatively rotate more laborsavingly with active joint B8 ', and simultaneously plane bearing 15 can make the active joint wearing and tearing unlike compressing screw 12, and its life-span is longer.The surfaces of revolution of described active joint A8 is provided with 1 to 4 annular groove 16, the surfaces of revolution of described active joint B8 ' is provided with and this annular groove 16 corresponding 1 to 4 annular protrusion 17, the rotating shaft coaxle of the central shaft of described annular groove 16 and annular protrusion 17 and active joint A8 and active joint B8 ', same like this can prevent effectively that active joint A8 is relative with active joint B8 ' and rotate the time surfaces of revolution seepage appears.
As Fig. 6, shown in Figure 7, described hold down gag comprises bolt 18 that is arranged in active joint A8 and active joint B8 ' and the nut 9 that is attached thereto, described active joint A8 and active joint B8 ' rotating shaft overlap with the central shaft of bolt 18, by adjusting nut 9 active joint A8 and active joint B8 ' are compressed.Described passage 11 and passage 11 ' can annular be provided with, and are positioned at bolt 18 outsides, and passage is unimpeded in the time of can not influencing active joint A8 and active joint B8 ' rotation like this.
During use, need open heater earlier and make the plastics refuse of having solidified in the hot flow path 2, then with the injection machine matched moulds, nozzle 7 can move horizontally to the solid plate direction along with the carrying out of matched moulds, and its opening part keeps over against die cavity.After finishing, matched moulds, arrives in the die cavity of injection machine through hot flow path 2 backs and nozzle 7 backs to hot-melt plastic being pressed into injection nozzle 1.Should first die sinking after injection moulding is finished, and then close the heater of hot flow path.
