。A mixing head body formed with a sliding hole passing through the interior, a raw solution injection port for spouting liquid plastic raw material into the sliding hole, and a raw solution return port for recovering the liquid plastic raw material, and a sliding hole of this mixing head body. A spool slidably fitted into the moving hole, and a spool provided in the length direction of the spool,
And circulation of liquid plastic raw material from the above-mentioned undiluted solution injection port to the undiluted solution return port! The spool slides in a mixing head of a reaction injection molding device that is equipped with a circulation groove that communicates a stock solution injection port and a stock solution return port, and that generates synthetic resin by colliding and mixing multiple liquid plastic raw materials at high pressure. A mixing head for a reaction injection molding apparatus, characterized in that a return groove of a predetermined length is formed on an inner wall surface of a sliding hole of a mixing head main body from the stock solution return port toward the stock solution injection port.
