<p>Provided are an injection molding device and a method for controlling the same, wherein high definition and energy saving can be induced in an injection device using electric motors; and energy saving can also be induced in a shape coupling device that needs to be pressed and coupled for a long time. The injection molding device (11) operates a screw (14) of the injection device (13) by means of electric motors (15, 16), and a shape coupling cylinder (18) of the shape coupling device (17) is performed by means of hydraulic pressure. The injection molding device (11) comprises a first pump (42) having an electric motor (45) always rotated to perform the operation of the shape coupling device (17); and a second pump (56) for supplying a hydraulic fluid by rotating the electric motor when the shape coupling cylinder is operated so as to stop or minimally rotate an electric motor (55) when any one actuator (15, 16, 24, 31, 35, 39) other than the shape coupling cylinder (18) is operated.</p> |
