Zusammenfassung: | To provide a control device for an injection molding machine that can appropriately manage a load factor even if a type of a molded product to be injection molded changes.SOLUTION: An injection molding machine 1 of the present invention comprises: a drive part having motors M1, M2, M3, and M4 for driving operating elements; and a calculation part 51 for calculating a load factor in time-variant units for each of the motors M1 to M4. The calculation part 51 calculates a load factor in association with identification information of the plurality of motors M1 to M4. The calculation part 51 calculates a load factor in association with the identification information of a mold used, and calculates one or both of a total first load factor for each of the plurality of molds, and a second load factor within a predetermined period in each of the plurality of the molds.SELECTED DRAWING: Figure 4
【課題】射出成形される成形品の種類が変わっても、適切に負荷率を管理できる射出成形装置の制御装置を提供すること。【解決手段】本発明の射出成形機1は、動作要素を駆動するモータM1,M2,M3,M4を有する駆動部と、モータM1〜M4のそれぞれに対し、時間的単位における負荷率を算出する演算部51と、を備える。演算部51は、複数のモータM1〜M4の識別情報と対応付けて負荷率を算出する。演算部51は、使用された金型の識別情報と関連付けて負荷率を算出するとともに、複数の金型のそれぞれにおける通算の第1負荷率、および、複数の金型のそれぞれにおける所定期間内の第2負荷率の一方または双方を算出する。【選択図】図4 |
