    摘要： A molding management system includes: a first acquisition unit configured to acquire first abnormality information, second abnormality information, and third abnormality information; and a first output unit configured to output first warning information. The second abnormality information and the third abnormality information include information on an injection molding machine in the first abnormality information and information on a type of an abnormality in the injection molding machine in the first abnormality information. The first acquisition unit acquires the second abnormality information after acquiring the first abnormality information and before a first period elapses therefrom, and acquires the third abnormality information after acquiring the first abnormality information and after the first period elapses therefrom. The first output unit outputs the first warning information when the first abnormality information is acquired, does not output the first warning information when the second abnormality information is acquired, and outputs the first warning information when the third abnormality information is acquired.

    摘要： When an injection molding machine performs molding, the mold clamping force on the mold is adjusted on the basis of a mold displacement of the mold or the injection peak pressure and injection foremost position so that the molding is performed without causing flash and by an appropriate mold clamping force with which energy can be reduced. The amount of mold displacement and also the injection peak pressure and the injection foremost position are monitored during automatic operation. If there occurs no mold displacement change exceeding a threshold or if there occurs no injection peak pressure anomaly or injection foremost position anomaly exceeding thresholds, the automatic operation is continued. If the mold displacement change occurs or if the injection peak pressure anomaly and the injection foremost position anomaly occur, the operation of the injection molding machine is stopped.

    摘要： An abnormality detection device includes a servo CPU; a physical quantity detection unit which detects a physical quantity such as a load applied on a servo motor which operates a movable part included in an injection molding machine. The abnormality detection device further includes a first storage unit directly readable/writable by the servo CPU; and a second storage unit not directly readable/writable by the servo CPU. A reference physical quantity is stored in the first and second storage units. The servo CPU outputs an instruction for stopping or decelerating the movable part in response to a first physical quantity deviation, which is a deviation between a reference physical quantity read from the first storage unit and a current physical quantity, or a second physical quantity deviation, which is a deviation between a reference physical quantity read from the second storage unit and a current physical quantity, exceeds a threshold value.
