Zusammenfassung:To predict an abnormality of a molded article due to unsealed gates.SOLUTION: An abnormality prediction system is provided with a molding device for molding a molded article, and an abnormality prediction device for predicting an abnormality of the molded article. The molding device has: a mold part formed with a cavity inside and having a gate that opens to the cavity; an injection part that performs a filling operation for filling the cavity with a molten molding material via the gate, a pressure keeping operation for keeping a pressure of the molding material filled in the cavity, and a kept-pressure releasing operation for releasing the kept pressure of the molding material; and a plurality of pressure sensors for detecting pressures of the molding material in the cavity at positions which differ in distance between the cavity itself and the gate. The abnormality prediction device has: a data acquisition unit for acquiring an evaluation value on the basis of a plurality of pressures detected by the respective plurality of pressure sensors after the kept-pressure releasing operation; and an abnormality prediction unit for acquiring prediction information for predicting an abnormality of the molded article on the basis of the evaluation value.SELECTED DRAWING: Figure 1 【課題】ゲートがシールされていないことに起因する成形品の異常を予測する。【解決手段】成形品を成形する成形装置と、前記成形品の異常を予測する異常予測装置と、を備える異常予測システムであって、前記成形装置は、内部にキャビティを形成し、前記キャビティ側に開口するゲートを有する金型部と、前記ゲートを経由して、前記キャビティへ溶融状態の成形材料を充填する充填動作と、前記キャビティに充填された前記成形材料の圧力を保持する保圧動作と、前記成形材料の圧力の保持を解除する保圧解除動作と、を行う射出部と、前記ゲートとの距離がそれぞれ異なる位置において、前記キャビティ内の前記成形材料の圧力を検出する複数の圧力センサと、を有し、前記異常予測装置は、前記保圧解除動作後に、前記複数の圧力センサによりそれぞれ検出される複数の圧力に基づいて、評価値を取得するデータ取得部と、前記評価値に基づいて、前記成形品の異常を予測するための予測情報を取得する異常予測部と、を有する、異常予測システム。【選択図】 図1
