Title:
INJECTION MOLDING CONDITION SEARCH ASSISTANCE DEVICE AND METHOD THEREFOR, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/210425
Kind Code:
A1
Abstract:
A prediction model generation unit (65) generates a prediction model for predicting quality relating to an unknown injection molding condition on the basis of advance data in which injection molding condition data and quality data for a molded article are associated with each other. The prediction model includes: (i) a prediction model for calculating a first probability distribution in which a quality prediction value and a distribution continuously change in accordance with a change in the injection molding condition; and (ii) a prediction model for calculating a second probability distribution in which the occurrence probability of a specific event continuously changes in accordance with a change in the injection molding condition. An injection molding condition determination unit 66 determines the next injection molding condition to be set in an injection molding machine on the basis of an evaluation of the first probability distribution relating to one or more qualities, an evaluation of two or more second probability distributions relating to two or more specific events, and/or an evaluation of at least one first probability distribution and at least one second probability distribution.
