To provide a good quality mold clamping machine that is suitable for a hollow molding machine or the like, for example.SOLUTION: A mold clamping machine 40 according to one embodiment comprises an electric servomotor 47 for moving a pair of movable plates 42a, 42b to which a pair of respective dies 41a, 41b are attached, in a direction of closing the dies 41a, 41b via a ball screw 48; and a hydraulic cylinder 46 for pressing one of the pair of movable plates 42a, 42b in the direction of closing the dies, that is attached to the one of the pair of movable plates. Both the electric servomotor 47 and the hydraulic cylinder 46 are operated when a moving distance of the dies from their initial positions is a predetermined distance or larger.SELECTED DRAWING: Figure 15 【課題】例えば中空成形機等に好適であって、良質な型締機を提供すること。【解決手段】一実施の形態に係る型締機４０では、一対の金型４１ａ，４１ｂがそれぞれ取り付けられた一対の可動盤４２ａ，４２ｂを、ボールネジ４８を介して金型４１ａ，４１ｂの閉じる方向に移動させる電動サーボモータ４７と、一対の可動盤４２ａ，４２ｂの一方に取り付けられ、当該可動盤を金型の閉じる方向に押圧する油圧シリンダ４６と、を備え、金型の初期位置からの移動距離が所定の距離以上になったときに電動サーボモータ４７と油圧シリンダ４６の両方を稼働させる。【選択図】図１５
