Abstract
A die casting machine and a control method for avoiding damage to devices by performing operation control of a hydraulic operating means and an electric servomotor, that are adapted as drive sources in an injection step, separately and not performing coordinate control. The die casting machine includes a tubular injection sleeve, an injection plunger, an electric servomotor and a hydraulic operating means that are used as a drive source of an injection step, and a control means which controls the electric servomotor and the hydraulic operating means separately, when injecting and filling the cavity of the mold, which has been closed, with the molten metal by the advancing of the injection plunger, during a low-speed injection step and a high-speed injection step which is performed at a higher speed than the low-speed injection step, in the injection step.
