Abstract
An injection molding machine that performs a safe ejecting action of a molded article until a setting state of an ejector rod and a set forward end position for an ejection stroke of a molded article ejector are suitable for a mold in use. A resistor Ris set to ON when a mold is changed and a resistor Ris set to ON when a set value of the forward end position of the ejection stroke is changed. When resistor Ror resistor Ris 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 Rand Rare 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.
