ABSTRACT:
A discharge apparatus for a two-stage injection molding machine, includes a check shaft seat having a runner, and disposed between a feeding portion and an injection portion of the two-stage injection molding machine, for allowing a plastic material in the feeding portion to enter the injection portion via the runner; at least one check shaft disposed in the check shaft seat, and for opening and closing the runner via movement of the check shaft; at least one cover provided at a side of the check shaft seat, and having at least one discharge hole for discharging residues of the plastic material between the check shaft seat and the check shaft; and at least one adjustable unit for adjusting a discharge speed of the residues of the plastic material. The discharge hole and the adjustable unit can prevent locking of the check shaft and pollution from degraded residues of plastic material.
