Abstract: To easily check a changing trend of machine state data on an injection molding machine during a predetermined period and/or in every predetermined period. An injection molding information management support device for managing machine state data regarding a machine state in operation of an injection molding machine during a predetermined period and/or in every predetermined period includes a machine state data acquisition unit that acquires a machine state data value for each molding cycle in the injection molding machine, and a frequency distribution data recording unit that converts the machine state data value into a preset class data value and records the class data value in a storage unit.

Abstract: A display device for an injection molding machine is a display device for an injection molding machine configured to control a display on a display unit, wherein, on the display unit, a plurality of display areas are provided beforehand by dividing a display screen into upper, lower, left, and right sections, the display device including a first display control unit configured to display content in any one of the plurality of display areas, without combining the plurality of display areas, and a second display control unit configured to display content in a combined area configured by combining a plurality of display areas that lie adjacent to each other.

Abstract: The management system has an injection molding machine and a management unit for managing the injection molding machine, wherein the management unit includes: a plurality of physical quantity measurement units configured to be provided at a plurality of movable parts included in the injection molding machine; an ascertainment unit configured to calculate, based on a plurality of physical quantity data respectively measured by the plurality of physical quantity measurement units, a comparative relationship representing a relational state of the plurality of physical quantity data between the plurality of the movable parts, and to ascertain whether the comparative relationship deviates from a preset reference comparative relationship; and an alarm unit configured to issue an alarm when the ascertainment unit ascertains that the comparative relationship deviates from the reference comparative relationship.

Abstract: A time Gt from the start of an injection step until a mold clamping operation is complete is compared with an operation time Ct for a mold clamping step. For Gt<Ct, the injection step is started when a time Dt equal to a difference between Gt and Ct elapses. On the other hand, for Gt?Ct, after the start of the injection step, a movable platen is stopped at a mold touch position until the time Dt elapses. When the time Dt elapses, the mold clamping step is started.
