Proposed is an electromagnetic vibration stirring device of semi-solid high pressure casting equipment. The electromagnetic vibration stirring device includes: a ring-shaped casing including an inner wall into which a sleeve is inserted and an outer wall spaced apart from the inner wall; and a magnetic field generating unit located between the inner wall and the outer wall of the casing, and including a plurality of electromagnets radially arranged at equal intervals around the sleeve in a circumferential direction of the sleeve, each of the electromagnets including a core and a coil surrounding the core. The magnetic field generating unit generates a magnetic field by applying a current to the electromagnets in a clockwise or counterclockwise direction, and each portion of a semi-solid molten metal is sequentially vibrated by the magnetic field along the circumferential direction of the sleeve, thereby controlling a microstructure of the molten metal.
