摘要:
An injection molding machine, comprising a cylinder member, an injection member disposed in the cylinder member so that it can be moved forward and backward, an injection motor (82), a rotation transmitting part which is connected relatively rotatably to the injection member and to which the rotation of the injection motor is transmitted, and a transmission shaft having a moving direction converting part for converting a rotational motion to a linear motion, wherein the injection motor and the transmission shaft are disposed on the same axis, the transmission shaft is moved forward and backward inside a rotor (92) of the injection motor, whereby a mechanical efficiency can be increased and an inertia can be reduced because the rotation of the injection motor is transmitted directly to the transmission shaft without passing through a speed reduction mechanism and pulleys, and the axial dimension of the injection molding machine can be reduced because the transmission shaft is moved forward and backward inside the rotor of the injection motor.

A motor-driven injection molding machine comprises an injection device which includes a heating cylinder for heating resin powder therein to melt the resin powder into molten resin and a screw disposed in the heading cylinder for feeding the molten resin in the heating cylinder forward to meter the molten resin. A controller (26) positions, in response to a position detected signal (S fb ) detected by a position detector (27), the screw at a metering position using an injection servomotor (11) on and immediately after completion of the plasticization and metering process. In addition, the controller (26) rotates, in response to a pressure detected signal (P fb ) detected by a load cell (18), the screw in the opposite direction using a screw-rotation servomotor (24) on and immediately after the completion of said plasticization and metering process to carry out depressurization of the molten resin in the heating cylinder that is metered ahead of the screw.

Provided is a temperature control method capable of causing the heating temperature by a heater to quickly converge to a target temperature in accordance with an environmental ambient temperature. An embodiment of a temperature control method comprises: a step (A) of obtaining, by means of PID control, a first energization rate y1 based on a first temperature difference e1 between an actually measured temperature Ta and a target temperature Ts; a step (B) of obtaining a second energization rate y2 based on a second temperature difference e2 between the ambient temperature Te of the environment in which a heating barrel 2 is disposed and the target temperature Ts; a step (C) of obtaining a corrected energization rate y on the basis of the result of comparison of the first energization rate y1 and the second energization rate y2; and step (D) of controlling the electrical power to be supplied to a heater 4 on the basis of the corrected energization rate y. In step (C), the corrected energization rate y is set to any of predetermined first, second, and third conditions on the basis of the comparison result.
