<p>In an injection molding machine comprising at least four motors (18 to 21) and a control section (22) for controlling the four motors to carry out a predetermined injection molding process divided into a plurality of steps, the four motors are grouped into first and second groups so that the motors of each group have driving durations which are not overlapped with one another and which may be overlapped with those of the motors of another group. The control section comprises first and second control units(24 and 25) coupled to the first-group motors and the second-group motors for individually and selectively controlling the first-group motors and the second-group motors.</p> |
