<p>An injection molding machine that performs a safe ejecting action of a molded article until a setting state of an ejector rod (2) and a set forward end position for an ejection stroke of a molded article ejector are suitable for a mold (1) in use. A resistor R1 is set to ON when a mold is changed and a resistor R2 is set to ON when a set value of the forward end position of the ejection stroke is changed. When resistor R1 or resistor R2 is ON, ejection is performed with a reduced ejecting force and at a reduced ejecting velocity. When a detected position of the ejector rod reaches the set forward end position, resistors R1 and R2 are turned OFF and thereafter the ejection is performed with a normal ejecting force and a normal ejecting velocity, to thereby prevent damage to the mold or to the molded article ejector.</p> |
