PROBLEM TO BE SOLVED: To provide an injection molding machine which is capable of surely ejecting residual moldings by enabling settings of conditions for the normal ejection motion and the re-ejection motion separately. SOLUTION: Residual moldings are removed by using ejecting motions with different ejector conditions between ejection and re-ejection. The number e of the ejecting motions is set at one time and the e of re-ejecting motions is set at three times. The ejector makes an advance motion and subsequently a retreat motion in a molding operation. After the retreat motion of the ejector is completed, the presence of remaining moldings is checked by means of an image and the like. The check by an image made after the ejector retreat motion in the molding operation is the first observation. When moldings are found to be still left as a result of the first observation, the re-ejecting motion is conducted. A single ejecting motion means three successive motions comprising the advance motions and the retreat motions of the ejector with e=1-3. Ejecting conditions during molding and ejecting conditions during re-ejection are different. COPYRIGHT: (C)2010,JPO&INPIT
