応射出成形機の混合ヘラ′ ド。1. A mixing head of a reaction injection molding machine, wherein a plurality of injection nozzles are provided in an injection cylinder that opens into a mixing chamber, and a spool having an opening/closing control section for the injection nozzles is provided in the injection cylinder so as to be freely movable in the axial direction. In the injection cylinder, the injection cylinder has a branch passage having one end opened to the opening of the injection nozzle and the other end opened to the inside of the injection cylinder, and an exit passage having one end opened to the inside of the injection cylinder and the other end opened to the outside. The spool is formed with a communication groove that communicates the branch passage with the outlet passage when the injection nozzle is closed by the opening/closing control unit, and a communication groove that establishes communication between the branch passage and the outlet passage when the injection nozzle is opened. Mixing head of a reaction injection molding machine characterized by being provided with a shut-off part=2 Utility model registration claim No. 2 characterized in that the diameter of the opening/closing control part is set smaller than the diameter of the shut-off part A mixing head for a reaction injection molding machine according to item 1.
