1. A two-segment electromagnet semi-solid die-casting apparatus comprising:
a mold member comprising a movable mold and a fixed mold;
an injection member comprising a sleeve and a plunger and configured to inject molten metal into the mold member; and
a two-segment electromagnet stirring member comprising a first electromagnetic stirring part and a second electromagnetic stirring part, the first electromagnetic stirring part being located at one end of the movable mold and being configured to be moved in conjunction with the movable mold and the second electromagnetic stirring part being located at one end of the fixed mold,
wherein the first electromagnetic stirring part is configured to be moved with movement of the movable mold to be coupled to the second electromagnetic stirring part to surround an outer circumferential surface of the sleeve, and the two-segment electromagnet stirring member is configured to perform electromagnetic stirring to the molten metal located in the sleeve.
 
4. A two-segment electromagnet semi-solid die-casting method comprising:
injecting molten metal into a sleeve of an injection member;
moving and coupling a movable mold of a mold member to a fixed mold, and allowing a first electromagnetic stirring part located at one end of the movable mold to be moved in conjunction with the movable mold to couple the first electromagnetic stirring part to a second electromagnetic stirring part located at one end of the fixed mold, thereby forming a ring-shaped two-segment electromagnet stirring member having a hollow portion;
inserting the sleeve into the mold member through a lower portion of the mold member while passing through the hollow portion of the two-segment electromagnet stirring member, and allowing the two-segment electromagnet stirring member located to surround an outer circumferential surface of the sleeve to perform electromagnetic stirring to the molten metal; and
injecting the electromagnetic stirred molten metal into the mold member as a plunger is moved.
