PROBLEM TO BE SOLVED: To easily confirm the abnormality of a pressure detector without detaching it from an injection molding machine.;SOLUTION: The injection molding machine 1 includes driving parts 29 and 46, driven parts 23 and 52 to which axial force is transmitted by the driving parts 29 and 46 and which are moved forward/backward, regulation means 5, 11, and 70 for restricting the forward/backward movement of the driven parts, pressure detectors 35 and 48 for detecting the axial force transmitted to the driven parts 23 and 52 as pressure, and a controller 45 for calculating driving force on the basis of a current value given to the driving parts 29 and 46 in order to control the movement of the driving parts 29 and 46 while the forward/backward movement of the driven parts 23 and 52 is restricted by the regulation means 5, 11, and 70.;COPYRIGHT: (C)2007,JPO&INPIT
