Zusammenfassung: | To provide a resin state estimation device that can estimate the melting state of resin in a cavity.SOLUTION: The resin state estimating device 3 includes a feature value generating unit 102 that generates a group of feature values [F] related to the detection data based on the detection data detected during molding by sensors 44, 45 attached to the injection molding machine 2, and a discriminating parameter value calculating unit 104 that calculates, based on the group of feature values [F] and the group of control parameter values [A], a discriminating parameter value P1-Pm corresponding to each feature value. The discriminative parameter value calculating unit 104 calculates the discriminative parameter values P1-Pm representing the melting state of the resin, and based on the discriminative parameter values P1-Pm, applies multivariate analysis using the discriminative parameter values P1-Pm as explanatory variables, and the section is equipped with a group acquisition section 107 that acquires groups G1 and G2 of the resin melt state.SELECTED DRAWING: Figure 3
【課題】キャビティ内の樹脂の溶融状態を推定することができる樹脂状態推定装置を提供する。【解決手段】樹脂状態推定装置3は、射出成形機2に取り付けられたセンサ44,45により成形時に検出された検出データに基づいて、検出データに関する特徴量群[F]を生成する特徴量生成部102と、特徴量群[F]および制御パラメータ値群[A]に基づいて、それぞれの特徴量に対応する樹脂の溶融状態を表す樹脂状態識別パラメータ値P1−Pmを演算する識別パラメータ値演算部104と、樹脂状態識別パラメータ値P1−Pmに基づいて、樹脂状態識別パラメータ値P1−Pmを説明変数とする多変量解析を適用することにより、樹脂の溶融状態のグループG1,G2を取得するグループ取得部107とを備える。【選択図】図3 |
