A method for automatically cutting off a material passage part while reducing manufacturing cost and cycle time. This method includes preparing a cutting device capable of moving in an automatic control coordinate system, placing the molded article without fixing the molded article, detecting a shape of the molded article by a sensor, acquiring a position of the material passage part in the coordinate system, determining a position of a cut spot in the material passage part as a target position in the coordinate system, moving the cutting device in the coordinate system and disposing the cutting device on a work position for cutting the cut spot, and cutting the cut spot by the cutting device arranged on the work position.

Method for cutting gate formed on molded article

Provided is an injection molding system that includes: a mounting position detection unit configured to detect a mounting position of a temperature control hose establishing connection from a mold temperature controller to a mold; and a temperature control hose attachment and detachment unit. Attachment and detachment of the temperature control hose is established by the temperature control hose attachment and detachment unit. By virtue of this feature, it is made possible to simplify the operator's tasks and achieve quick attachment and detachment of the temperature control hose in a short period of time.

Injection molding system

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.

Injection molding machine

An average is obtained between output readings of a pressure sensor obtained when forward and reverse thrusts are applied to an injection screw by positively driving a servomotor for injection. The average value is used as a correction value for a reading deviation of the pressure sensor. The injection servomotor is positively driven to apply a thrust to the screw. This known thrust and the actual reading of the sensor are compared. A deviation between these values is used as the correction value for the reading deviation of the sensor.
