ト射出成形機。 A raw resin falling port is formed at the rear of the cylinder.
A vent port is formed in the middle of the cylinder, and the volume of the vent port is larger than the volume of the resin transfer gap formed between the screw groove and the inner wall surface of the cylinder from the front end of the raw resin falling port to the rear end of the vent port. In order to increase the volume of the resin transfer gap formed between the screw groove and the inner wall surface of the cylinder in the portion from the front end to the front end of the screw groove,
A vent injection molding machine in which the volume relationship of the resin transfer gap is set.
