The specific embodiment

The present invention will be further described in conjunction with the accompanying drawings, and before the work, injection device 9 is in the top of first station 21, and injection device center line and mould V center line are on same axis.The mould that screw pump stator metallic sheath and helical form core are assembled, in the jacket type vulcanization plant of packing into, earlier with deep fat by interlayer with mold heated to predetermined technological temperature.During work, motor 14 energisings, the main shaft 29 of worm gear reducer 15 drives nut 27 through flat key 28 and rotates, and spiral 25 moves downward, and movable plate 8 is moved down along lead 13, and drive injection device 9 moves down.When nozzle 18 and injection port 12 pressed to certain pressure, the pressure sensor of nozzle top sent signal, and motor 14 quits work, and pressing stops.At this moment, injection device is injected into the die cavity of being made up of stator metallic sheath and helical form core with high temperature, high pressure, at a high speed materials flow, is full of fully until die cavity, and when reaching setting pressure, stops to inject.Motor 14 counter-rotating, spiral 25 moves upward, and drives to move on movable plate, the injection device and reset, and motor 14 quits work.Screw pump stator sizing material in the mould enters sulfided state under pressurize, thus, finish the injection moulding of first station.Then, drive motors 36 energising work, transverse moving mechanism III drives sprocket wheel 32 and rotates by projecting shaft 37, coupling band 44, the projecting shaft 33 of reduction box 35, and chain 38 is laterally moved, chain drives an iron seat 42, making the back go up rail plate 40 laterally moves along slide block 39, rail plate is by entablature 5, lead 13 and sill 2 on the back, go up rail plate 17 before making, forward and backward lower

slider guide rail

19,11 moves along the slide block synchronous horizontal, when the injection device center line arrived the mold center line top of second station 22, drive motors 36 quit work.Motor 14 energising work are injected by the processing step of first station subsequently.After the injection of second station is finished, drive motors 36 work, the process that transverse moving mechanism moves to second station by above-mentioned first station moves to the 3rd station 23, and injects by the processing step of first station.After the injection of the 3rd station was finished, drive motors 36 backward rotation made transverse moving mechanism get back to first station, and the injection device center line arrives the top of mold center's line.Take out stator metallic sheath and helical form core if the mould of first station is finished vulcanization process at predetermined cure time this moment, changes new stator metallic sheath and helical form core, in the jacket type vulcanization plant of packing into, begins the injection of following one-period.Equally,, when finishing vulcanization process, take out stator metallic sheath and helical form core, change new stator metallic sheath and helical form core at the mould of second station and the 3rd station, in the jacket type vulcanization plant of packing into, stand-by.
