摘要：
A motor is driven in a state where the moving platen (22) of an injection molding machine is not mounted with a mold to protrude an ejector rod (27), and the driving current of the motor is measured for each predetermined protrusion position. Then, the moving platen (22) is mounted with a mold (28b) and the motor is driven to protrude the ejector rod (27), and the driving current of the motor is measured. It is determined that an ejector rod protrusion position where a difference between this measured current value and a current value stored in a data table becomes larger is the protrusion start position of an ejector pin.
