The specific embodiment

The utility model will be further described in conjunction with the accompanying drawings, before work, injection molding apparatus I is in first station, 62 home positions, during the injection beginning, the motor 7 energising work of the clamping apparatus V of first station, 62 belows, spiral 8 is rotated and move upward, promoting boss 21 and moving platen 19 upwards moves as matched moulds along template guide pillar 9, when counterdie 20 arrived certain tonnage with patrix 18 matched moulds, the locked mode tonnage sensor of clamping mechanism V sent signal, and motor 7 quits work, the then motor 34 energising work of press fit device 14, the projecting shaft 33 of reduction box 35 is rotated, drive leading screw 23 and rotate, under the effect of the nut 24 of screw pair 25, crossbeam 12 is moved downward along lead 11, make the

nozzle

1 and 16 pressings of patrix injection port of injection device 3, when reaching predetermined pressure, pressure force is passed to coupling band 37 by the reaction force of leading screw, pass to taper roll bearing 31 again, affact pressing tonnage sensor 32 at last, and send signal, motor 34 quits work; At this moment, Coinjection molding apparatus 3 injects die cavity with the sizing material of high temperature, high pressure, high speed, when being full of die cavity and reaching setting pressure, the pressure sensor 2 that is installed in head sends the signal that stops to inject, and finishes injection, meanwhile, motor 34 counter-rotation of press fit device 14 rise injection device 3 and reset, and the goods in the mould begin sulfuration and timing, so far, finish the injection moulding operation of first station 62.Subsequently, begin injection by time of technological requirement to second station 63, at this moment, the motor 38 energising work of multistation mobile device II, the output shaft 41 of reduction box 39 is rotated, driving sprocket wheel 42 rotates, the multistation mobile device is moved to the second station direction along chain 43, thereby driving fixed cross beam 15 moves along guide rail 44 by slide block 46, make injection molding apparatus I in two cover

rail plate mechanisms

30,45 with entering second station 63 under the moved further, motor 38 outages quit work, then still inject by the job step of first station 62, after 63 injections of second station finished, the action by a last station moved to the 3rd station 64 with injecting systems equally, and injects by a last station step.So far, three stations are all finished injection, motor 38 energising counter-rotatings, and injecting systems I gets back to first station.In the entire job process, if first station 62 when predetermined cure time is finished vulcanization process, the motor of clamping apparatus V 7 energising and backward rotation descend spiral 8, drive counterdie and reset, motor 7 quits work.The then single phase ac variable speed electric motors, particularly 61 energising work of mould emptier IV; make cylinder tooth bar 53 up by linear gear case 51; distance rod 60 is up; demoulding gusset piece 59 is up along three leads 55, and five knockout pins 58 are stretched out from the preformed hole of moving platen 19 and counterdie 20, ejects rubber 57; realize the demoulding; 61 counter-rotatings of single phase ac variable speed electric motors, particularly reset knockout pin 58, and quit work.Equally, the clamping apparatus of second station and the 3rd station and stripper apparatus are finished the above-mentioned demoulding.Begin to enter the injection moulding step of following one-period simultaneously.
