PURPOSE: A mixing nozzle for injection molding is provided to accurately express desired color on a molded product by uniformly mixing liquid resin and pigments in a mixing bowl. CONSTITUTION: A mixing nozzle for injection molding comprises a nozzle body(100), first and second mixing containers(200,300), and a mixing bowl(400). The nozzle body has a jetting unit(110) on a side and a joint unit(120) on the other, wherein the diameter of a discharge hole of the jetting unit is tapered to the outer end and a joint hole(121) of the joint unit is connected to the discharge hole. The first mixing container has a plurality of jetting holes(211) which are formed in a partition wall(210) contacting the discharge hole. The second mixing container has a plurality of inlet holes(311) which are formed in a wall(310) facing the outer end of the joint hole. The mixing bowl is received between the first and second mixing containers, in which liquid resin and pigments are uniformly mixed through vortex or rotation.
