PURPOSE: A coolant supplying apparatus and a mold cooling apparatus are provided to control temperature of the coolant according to the temperature change or environment automatically and to improve cooling efficiency of the mold. CONSTITUTION: A coolant supplying apparatus comprises a water tank(100), a connecting body(210), an upper cylinder(220), a cylindrical pumping case(230), a pumping case cover(240) and a median pipe(250). The connection body comprises a first flow path(213) and a first check valve(v1). The upper cylinder is moved along an inner diameter of a first piston. The cylindrical pumping case is located inside the water tank. The both ends of the cylindrical pumping case are opened according to the up and down movement of a second piston. The pumping case cover has a second check valve(v2) and a second flow path(243), and inhales the coolant into the pumping case inside. The coolant is discharged to the outside through the second flow path.
