Claims

[Scope of utility model registration request]

An injection molding machine used in combination with a fixed mold of a split mold, comprising a discharge port communicating with a gate hole of the fixed mold, and an injection chamber for supplying molding material into a mold cavity through the discharge port. , a raw material supply unit that supplies the molding material to the injection chamber, and a raw material supply unit that is slidably disposed in the injection chamber, and when moving forward, the molding material is injected into the mold cavity from the discharge port through the gate hole, and when it is retreating, the molding material is injected into the mold cavity. A metering piston that introduces the material from the raw material supply section into the injection chamber, and a metering piston that slides in contact with the metering piston but moves independently of the metering piston and slidably moves within the discharge port and gate hole to discharge the material. An injection molding machine comprising: a press-off rod that opens and closes an outlet and presses and presses a molding material injected into a mold cavity;
