PROBLEM TO BE SOLVED: To accurately measure dynamic deformation of a press die in press molding, without having to attach a sensor to a press die. SOLUTION: An apparatus for measuring dynamic deformation of the press die includes the press die 11 having a lower mold 13 and an upper mold 14, and a measurement tool body 33 detachably disposed at an interval from a pressing machine body 10, having a bolster 16 and a slider 17, and measures the dynamic deformation of the press die 11 in press molding. An eddy current displacement sensor for detecting the amount of elastic deformation of the press die 11 is provided on a horizontal bar 41, both the ends of which are slidably supported on the measurement tool body 33. A distortion gage for detecting a pressure distribution of the press die 11 is provided on a load receiving piece 36 provided on the measurement tool body 33. COPYRIGHT: (C)2011,JPO&INPIT
