Claims

[Scope of utility model registration request]

In an injection device in which a molding material extrusion member serving as a screw or piston mechanism is inserted into a molding material flow path communicating with an injection hole formed in an injection nozzle, a spring means is provided at the tip of the extrusion member on the side of the injection hole. Alternatively, an air bleed valve that protrudes and retracts due to fluid pressure is installed, and the air bleed hole formed in the air bleed valve opens the flow passage when the air bleed valve protrudes, and closes when the air bleed valve is retracted. An injection device characterized in that the extrusion member is provided with a suction air recovery hole that communicates with the air vent hole.
