PURPOSE: An injection molding device is provided to achieve three color working in one cycle, to improve productivity and to automate an injection system. CONSTITUTION: Upon lifting up of a piston of a main cylinder, a kicker cylinder is lifted up to lift up a hexagonal support is lifted up. A position determining locker rotates the hexagonal support until the hexagonal extension is placed in a specific position. Thereafter, the kicker cylinder is lifted down and so is the piston of the main cylinder. For work of first, second and third molds, first, second and third injection cylinders are sequentially moved forward and backwardly. After complete work of the molds, the main cylinder is lifted up to lift up the hexagonal support via the kicker cylinder. Thereafter, a robot arm takes out an injected product after an ejector is hit. Therefore, three color work is completed in one cycle and an injection system is automated.
