<p>A controller for an injection molding machine repeatedly executes a plastic removal procedure in which a rotation movement of a propeller, a backward movement of the propeller and a forward movement of the propeller are combined until a predetermined number of these combinations are achieved. Then, every time when the continuous plastic-removing procedure is completed, the control is in a 'Standby' state until a start enabling signal which enables the start of a subsequent continuous plastic-removing procedure is input to the injection molding machine. In this way, plastics are prevented from being stored in certain locations in an undesirable amount.</p> |
