ABNORMALITY PREDICTION SYSTEM, ABNORMALITY PREDICTION DEVICE, ABNORMALITY PREDICTION METHOD, PROGRAM, AND LEARNED MODEL

Japanese Patent JP2022077628

A

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
