Injection molding machine

An injection molding machine comprising:

• an ejector rod that is used to protrude a molding product from a mold;
• a driving source that moves the ejector rod in an axial direction of the ejector rod;
• a controller that controls the driving source;
• a position detector that detects the position of the ejector rod;
• and
• an operations unit that receives an input operation input by a user,
• wherein, the controller sets up a current position of the ejector rod, which is detected by the position detector when the operations unit receives a first button operation operated by the user, to be a waiting position of the ejector rod after protruding the ejector rod or to be a protruding position of the ejector rod,
• the controller sets up a value of the current position of the ejector rod to be a value of the waiting position, and
• the controller calculates a deceleration position from which a setup speed of the ejector rod is decelerated while the ejector rod moves from the protruding position to the waiting position based on the current position of the ejector rod, the current position being detected by the position detector when the operations unit receives the first button operation by the user.
