Zusammenfassung:	PROBLEM TO BE SOLVED: To certainly stop the driving of a drive part corresponding to the load applied to the drive part. SOLUTION: The molding machine has a fixed platen for attaching a fixed mold, the movable platen arranged in opposed relation to the fixed platen to attach the movable mold, a drive part driven in order to allow the movable platen to advance and retreat and an abnormality judge processing means for stopping the driving of the drive part when a result value exceeds the restriction value expressed by a predetermined function in the monitor section set to the position where the fixed mold and the movable mold approach each other. Since the driving of the drive part is stopped when the result value exceeds the restriction value expressed by a predetermined function, the driving of the drive part can be certainly stopped corresponding to the load applied to the drive part when abnormality is produced.
