摘要： A nozzle internal resin pressure feedback control system has a mold internal pressure sensor for measuring a mold internal resin pressure as a measured mold internal pressure value. The measured mold internal pressure value is fed to the nozzle internal resin pressure feedback control system, and a nozzle internal pressure preset value in the nozzle internal resin pressure feedback control system is changed in accordance with a difference between the measured mold internal pressure value and the mold internal pressure preset value.

摘要： A screw head is composed of a cone portion, a tapered portion formed behind the cone portion and a narrow portion formed behind the tapered portion. A counter-flow stopper ring is provided around the narrow portion so that an annular resin passage is formed between the counter-flow stopper ring and the narrow portion. The tapered portion of the screw head has a plurality of circumferentially spaced grooves. The sectional area of each groove decreases from the inner circumference toward the outer circumference of the tapered portion. The grooves are so formed that the resin flowing through the grooves creates a force which pushes the counter-flow stopper ring backward, the ring being moved forward by forward flow of resin caused during backward movement of the screw. Thus, the grooves help maintain a gap between the counter-flow stopper ring and the screw head.

摘要： A back-flow prevention apparatus includes a screw which includes a metering portion and a screw head; a seal ring which is removably disposed on a rear portion of the screw head and which has a first resin passageway formed therein; a back-flow prevention ring which is disposed on a front portion of the screw head in such a manner as to be rotatable with respect to the seal ring and which has a second resin passageway formed therein; and a drive unit for selectively rotating the screw in a regular or reverse direction. A first positioning mechanism is disposed between the screw head and the seal ring and adapted to position the seal ring at a predetermined position with respect to the screw head. A second positioning mechanism is disposed between the screw head and the back-flow prevention ring and adapted to establish communication between the first resin passageway and the second resin passageway when the screw is rotated in the regular direction and to break the communication between the first resin passageway and the second resin passageway when the screw is rotated in the reverse direction. The second positioning mechanism also positions the back-flow prevention ring with respect to the screw head. The back-flow prevention apparatus can prevent resin movement associated with suck-back.
