Abstract

Disclosed is an injection molding machine comprising (a) a movable die plate for mounting the movable die, (b) a housing with a toggle mechanism, (c) a pressure sensor placed between the movable die plate and the housing, (d) a servo motor for driving a toggle mechanism, (e) and servo motors for injection control, wherein in a resin filling process, a reactive force of the movable die due to filling resin in the die cavity is detected by the pressure sensor, resin injection into the die cavity is feedback-controlled based on an output data of the resin filled from the pressure sensor, and in a die compression process and a following pressure-holding process, the feedback control on the die clamping force by the servo motor and position control of the movable die are carried out based on the data from the pressure sensor.
