PURPOSE: A cube injection mold capable of simultaneously multi-injecting and multi-extracting cube blocks and a manufacturing method thereof are provided to remarkably shorten a cycle time by simultaneously injecting, cooling, and extracting the same and to continuously manufacture the same. CONSTITUTION: A cube injection mold capable of simultaneously multi-injecting and multi-extracting cube blocks comprises upper and lower molds (10,20), upper and lower hot runner systems (111,211), a cube block (30), and an actuator (40). The actuator rotates a shaft to rotate a rotational movement of the cube block turning forward 360 degrees at 90 degrees increments. When a predetermined cooling time passes during the injection, the cube block rotates by 90 degrees by the actuator after the mold is opened and the injection molding and the extracting are repeated after the cube block is combined.
