摘要： A method for detecting an abnormality of a hydraulic system in a molding machine which comprises a hydraulic cylinder for reciprocating a movable member of the molding machine, a valve for controlling a hydraulic fluid which is supplied into the hydraulic cylinder, and a pair of pressure sensors attached to the hydraulic cylinder, for detecting the pressures in a pair of pressure chambers of the hydraulic cylinder, is disclosed. The method comprises the steps of: holding the valve at a neutral position, and comparing the pressures in the pair of pressure chambers with a preset range of pressure on the basis of detecting signals from the pair of pressure sensors, when the movable member is inoperative; and outputting an abnormality signal when at least one of the pressures in the pair of pressure chambers is out of the preset range of pressure.

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： A vibration sensor detects first data of a first component group and second data of a second component group. An injection molding machine performs diagnosis processing for diagnosing the first component group based on the first data in an injection mode and performs diagnosis processing for diagnosing the second component group based on the second data in a plasticization mode.

摘要： An injection molding machine having vent mechanism includes a plastication device, an injection device, a junction, a vent-up sensor, and a controller. The vent-up sensor detects vent-up. When the vent-up is detected, the controller switches from normal conditions to vent-up suppression conditions. The vent-up suppression conditions have at least one of the followings: increasing a rotational speed of the plastication screw to be higher than that in the normal conditions; using retreat-metering when the retreat-metering is not performed in the normal conditions, wherein in the retreat-metering, in addition to a pressure of the resin material, a force in a retreat direction is applied to the injection plunger to move the injection plunger at a predetermined retreat speed in the metering; and increasing the retreat speed of the injection plunger to be higher than that in the normal conditions when the retreat-metering is performed in the normal conditions.

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.
