機の混合ヘツド。[Claims for Utility Model Registration] A spool is inserted into the sliding hole of the head body so that it can move forward and backward, and by moving the spool forward and backward, a mixing chamber is formed in the sliding hole, and the liquid plastic is inserted into the mixing chamber. In a mixing head of a reaction injection molding machine in which a plurality of injection nozzles for injecting raw materials are provided in the head main body, the inner wall surface of the sliding hole of the head main body is in direct communication with the injection nozzles or the spool is advanced. A mixing head for a reaction injection molding machine, characterized in that a lubrication groove is provided that communicates indirectly through the spool.
