Abrasion amount estimation device and abrasion amount estimation method for check valve of injection molding machine

摘要

An abrasion amount estimation device stores a learning result obtained through supervised learning performed based on a feature amount, which is extracted from a physical amount which is acquired in injection performed by an injection molding machine, and information related to an abrasion amount of a check valve which has been attached to the injection molding machine in the injection. The abrasion amount estimation device estimates an abrasion amount of a check valve which has been attached to the injection molding machine in the injection based on the learning result which is stored and the feature amount which is extracted.
