反応射出成形装置。A reaction injection molding device that injects two or more reaction liquids into the mold cavity and foams and hardens them to produce a synthetic resin molded product, with one end communicating with the mold gate and the other end connected to a pressure reducing machine. a first decompression passage with one end connected to the tip of the cavity far from the gate and a second end connected to the decompression machine with the other end.
The control means causes the pressure reduction through the pressure reduction passage and the first ↓ pressure reduction passage to start after the completion of injection, and the pressure reduction through the second pressure reduction passage is performed from the time of injection by setting the pressure reduction value from atmospheric pressure to a value smaller than that on the first pressure reduction passage side. A reaction injection molding device characterized by comprising:
