PURPOSE: A quantitative feeder for an injection-molding device is intended to provide uniform color of injection molded products through precise discharge of an amount of a raw material. CONSTITUTION: A quantitative feeder for an injection-molding device comprises a body part(10), a quantitative basket, and a power source. The body part comprises a receiving hole(5), a discharge hole, and a cylindrical space. Coloring material supplied from a coloring hopper is put into through the receiving hole. The discharge hole discharges the coloring material. The cylindrical space is communicated with the receiving hole and the discharge hole. The column-shaped outer surface of the quantitative basket is engaged with the cylindrical space of the body part. The quantitative basket is rotatably mounted in the body part. The coloring-material chamber of the quantitative basket holds an amount of coloring material through an opening corresponding to the receiving hole or the discharge hole according to a rotated state. The power source supplies torque to the quantitative basket.
