Molding machine

Abstract

A die casting machine includes a plurality of ejector pins capable of advancing and retracting together with respect to the internal portion of a die; an electric motor capable of driving the plurality of ejector pins; a position sensor capable of detecting the positions of the plurality of ejector pins; a force sensor capable of detecting the pressure which is given to the molding material inside the die by the plurality of ejector pins; a display device capable of displaying images, and a control device controlling the electric motor and display device. The control device includes a drive control part which controls the electric motor so as to generate a driving force making the plurality of ejector pins advance to the inside of the die after the start of injection and before die opening, and a display control part which controls the display device so as to display the position detected by a position sensor and the pressure detected by a force sensor along a common time axis.
