Summary:Provided is an injection device for an injection molder. The injection device comprises: a pump; a screw moved forward and backward or rotated by oil supplied from the pump; a release pipe guiding the oil so that the oil used for driving the screw can be released to a drain part. The release pipe further includes: a relief pipe on which a relief valve is installed so as to apply resistance pressure to the screw when the screw moves backward; and a bypass pipe which is coupled to the relief pipe in parallel and on which a bypass valve is installed so as to determine whether the oil should flow along the relief pipe. 본 발명은, 펌프, 상기 펌프로부터 공급된 오일에 의해 전후진 또는 회전 이동하는 스크류 및 상기 스크류의 이동에 사용된 오일이 드레인부로 인출되도록 오일의 이동을 안내하는 배출관을 포함하고, 상기 배출관은, 상기 스크류의 후진 이동시 상기 스크류에 저항 압력을 제공하기 위한 릴리프 밸브가 설치되는 릴리프 배관 및 상기 릴리프 배관과 병렬로 연결되고 상기 릴리프 배관을 따라 오일이 이동할지 여부를 결정하기 위한 우회밸브가 설치되는 우회배관을 포함하는 사출성형기의 사출장치를 제공한다.
