PURPOSE: A dust separating device of raw materials for injection molding is provided to easily remove dust from a pellet of the raw materials injected into an injection molding device by using at least one cyclone dust collector. CONSTITUTION: A dust separating device(20) of injection molding raw materials comprises at least one cyclone dust collector(25,45). The cyclone dust collectors separate dust from the raw materials by rotating the raw materials and dropping with centrifugal force. The cyclone dust collectors comprise inlets(28,48), dust filters(38, 58) in a taper pipe shape, outlets(30, 50), dust chambers(36, 56), and dust vents(32, 52). The raw materials are flowed through the inlets. The dust filters separate the dust from the flowed raw materials. The raw materials separated from the dust are discharged through the outlets. The dust chambers are prepared on the exterior of the dust filters. The dust collected in the dust chambers is discharged to outside by the dust vents. [Reference numerals] (15) Dryer; (21) Ionizer
