Document Type and Number:
Japanese Patent JP7315441
Kind Code:
B2
Abstract:
Provided is a technique capable of suppressing an overload state of an actuator which drives a pressurizing device used to pressurize a molding material to be charged into a mold device such as an ejector device or a core tractor device in an injection molding machine. An injection molding machine (10) according to an embodiment of the present disclosure comprises: an ejector device (200) including an ejector rod (210) which pressurizes a molding material to be charged into a mold device (800) and an ejector motor (221) which drives the ejector rod (210); a control device (700) for controlling the ejector motor (221); and a display device (760). The display device (760) displays a setting screen (1000) for setting a control torque pattern of the ejector motor (221) by the control device (700), based on a fluctuation pattern of a mold internal pressure, which represents a force opposing the drive of the ejector motor (221), in a cavity space (801) of the mold device (800).
