Summary:Provided by the present invention is an ejector device capable of alleviating limitations of an installation position of an ejector rod. The ejector device (200) has an ejector rod (230), a cross head (222) on which the ejector rod is installed, a ball screw nut (224) on which the cross head (222) is installed, and a ball screw shaft (223) which is coupled with the ball screw nut (224) through screw. The ball screw nut (224) and the ball screw shaft (223) move the ejector rod (230) installed in the cross head (222) back and forth. The ball screw nut (224) has a flange unit (224a) forming a mounting part with the cross head (222). The cross head (222), as an area, on which the flange unit (224a) is mounted, has a flange mounting area (A) which is an inner area on the outer edge of the mounted flange unit (224a). The ejector rod (230) is mounted on the flange mounting area (A). 이젝터 로드의 장착위치의 제약을 완화할 수 있는 이젝터 장치를 제공한다. 이젝터 장치(200)는, 이젝터 로드(230)와, 이젝터 로드(230)가 장착되는 크로스헤드(222)와, 크로스헤드(222)에 장착되는 볼나사너트(224)와, 볼나사너트(224)와 나사결합하는 볼나사축(223)을 갖고, 볼나사너트(224)와 볼나사축(223)으로, 크로스헤드(222)에 장착된 이젝터 로드(230)를 전후진시킨다. 볼나사너트(224)는, 크로스헤드(222)와의 장착부를 구성하는 플랜지부(224a)를 갖는다. 크로스헤드(222)는, 플랜지부(224a)가 장착되는 영역으로서, 장착되는 플랜지부(224a)의 바깥가장자리의 내측영역인 플랜지장착영역(A)을 가지며, 플랜지장착영역(A)에 이젝터 로드(230)가 장착된다.
