摘要： In order to reduce the size and weight of an electric die casting machine and make it possible to perform predetermined injection operation and intensification operation without the necessity of controlling the ON and OFF operation of a clutch for supplying motive power, the electric die casting machine is provided with: a screw shaft (5) which is held rotatably, a nut body (7) which is threadably mounted on the screw shaft (5) so as to be able to move forward and backward, an injection plunger (9) which moves forward and backward in conjunction with the forward and backward movement of the nut body (7); an injection electric servo motor (10) and an intensification electric servo motor (11) which drive and rotate the screw shaft (5); and a one-way clutch (12) which is disposed between the screw shaft (5) and the intensification electric servo motor (11), wherein: the intensification electric servo motor (11) is started up during deceleration control of the injection electric servo motor (10) in a high-speed injection step, and the torque of the intensification electric servo motor (11) is transmitted to the screw shaft (5) via the one-way clutch (12) so that an intensification step can be performed following the injection step.
