Title:
DIE WITH DEVICE MONITORING MOLDING FAILURE
Document Type and Number:
Japanese Patent JP2013244623
Kind Code:
A
Abstract:
To solve a problem that generally, a scorch that is typical failure in plastic injection molding is discovered after product inspection and then a measure is taken against the scorch, but if the discovery of the failure delays, large amount of defective products are generated and man-hours related to correction increase, requiring development of a device capable of sensing scorches during molding.
A gas detection sensor detecting gas generated during molding and a light detection sensor detecting ignition light caused by gas combustion and ignition are embedded in a die, and monitoring is performed online to sense scorches during the molding.
