Abstract
A device for detecting galling which may produce deformations during an ejection process of die castings from a die. The device includes a setting device for storing a predetermined set value, the predetermined set value including an upper limit of acceleration of an ejector plate during the ejection process and a predetermined time period during the ejection process. An accelerometer is disposed to the ejector plate for measuring the acceleration thereof during the ejection process. A computing device is provided for comparing the acceleration measured by the accelerometer with the predetermined set value and outputting a warning signal when the acceleration measured at the accelerometer exceeds the upper limit during the time period. Thus, timely detection of galling can result.
