Abstract: PURPOSE: A die casting device and a producing method thereof are provided to perform a semi-solid forming for obtaining a product having a uniform physical property without pores. CONSTITUTION: A die casting device contains a heating container (20) storing a specific amount of molten liquid, and a pressing instrument (30) cooling the molten liquid from the heating container for supplying a die formed by a fixed die (10a) and a movable die (10b). Herein, heaters (23) and cooling apparatuses (24) are installed on the heating container. In discharging the molten liquid through an outlet (21), the liquid is cooled for a first time. The molten liquid is supplied to a die by the pressing instrument according to manipulation of a blocking unit (22). Herein, the pressing instrument is formed by a cylinder typed main body (31) connecting to the die, a plunger (32) installed in the main body, and a cooling unit (33) installed at the main body. The plunger contains agitating protrusion (36) on a front surface of a piston (35) contacting with the main body for pressing and agitating the molten liquid charged in the main body. Therefore, the molten liquid is injected to the fixed die and the movable die while being pressed and agitated.
