Zusammenfassung:Disclosed are an injection molded product cutting device and an injection molded product cutting method using the same capable of separating a finished product from waste by cutting an injection molded product in which the finished product and the waste are connected to each other. The injection molded product cutting device comprises a jig, a cutter blade, and an interval measuring device. The jig is moved in a state of mounting the injection molded product and is stopped during work for cutting the injection molded product. The cutter blade is linearly moved in a vertical first direction, a second direction which is parallel with a virtual boundary line for dividing the finished product and the waste in the injection molded product mounted on the jig, and a third direction which is orthogonal to the first and second directions. The interval measuring device measures an interval between the boundary line and an edge of an end of the cutter blade in the third direction. When the interval measured by the interval measuring device exceeds a predetermined allowable error, the cutter blade moves the injection molded product in the second direction to be cut and separates the finished product from the waste after being moved in the third direction to allow the interval between the boundary line and the edge of the end of the cutter blade to be smaller than or equal to the allowable error. 완제품과 웨이스트(waste)가 이어진 사출 성형품을 절단하여 완제품을 웨이스트에서 분리하는 사출 성형품 절단 장치, 및 이를 이용한 사출 성형품 절단 방법이 개시된다. 개시된 사출 성형품 절단 장치는, 사출 성형품이 안착된 상태로 이동하는 것으로, 사출 성형품을 절단하는 작업이 진행되는 동안 정지하는 지그(jig), 수직 방향인 제1 방향, 지그에 안착된 사출 성형품에서 완제품과 웨이스트를 구분하는 가상의 경계선과 평행한 제2 방향, 및 제1 방향 및 제2 방향에 모두 직교하는 제3 방향으로 직선 이동 가능한 커터 블레이드(cutter blade), 및 제3 방향으로 경계선과 커터 블레이드 말단의 엣지(edge) 사이의 간격을 측정하는 간격 측정기를 구비한다. 간격 측정기에 의해 측정된 간격이 미리 설정된 허용 오차를 초과하면, 커터 블레이드는 경계선과 커터 블레이드 말단의 엣지 사이의 간격이 허용 오차보다 작거나 같아지도록 제3 방향으로 이동한 후에 사출 성형품이 절단되도록 제2 방향으로 이동하여 완제품을 웨이스트에서 분리한다.
