PURPOSE:To enhance the operation efficiency by attaching a movable receiving segment constituting a part of an injection position side and a mold opening position side of a receiving member to a cylinder rod driven upwardly and downwardly to carry out the molding even during exchange of a metal mold. CONSTITUTION:If a turning roller 22b of one metal mold frame 1 is turned into a movable receiving segment 8 in a mold opening position B, the turning roller 22b of other metal mold frame 1 apart 90 deg. to a rotating direction of a rotary plate 3 is simulataneously turned into a movable receiving segment 11 to stop the rotary plate 3. In this time, if mold opening cylinders 6, 13 are moved forwardly to lower cylinder rods 6a, 13a respectively, the movable receiving segments 8, 11 are lowered to lower a movable frame member 22 and the metal mold 1 is a mold opening position B and the mold 1 in an injection position A are opened. Moreover, if a pressure increasing cylinder 7 is moved forwardly, a movable frame member 22 of a metal mold frame 2 in the injection position A is lifted and a mold closing pressure of the metal mold in the injection position A is increased. |
