Abstract

PURPOSE:To aim at enhancing the accuracy of positioning a stop in intermittent feed, by separatably supporting a mold transfer plate with the use of a stationary beam and a vertically and transversely movable beam which is arranged in parallel with the stationary beam. CONSTITUTION:The piston rod 64 of a fluid pressure cylinder 53 is retracted to stand upright swing arms 53, simultaneously, through a connecting rod 59, and support rollers 56 are moved along a rail-like receiving section 57. Thereby a movable beam 32 ascends with its horizontal posture being held, and takes a position above a stationary beam 32. Accordingly, a mold transfer plate 11 which is fitted onto and therefore positioned by a projection formed on the rail- like stationary support section 25 of the stationary beam 22, is shifted onto the movable beam 33 so that the mold is positioned by a projection 35. Then the movable beam 32 is advanced, and descends after being reversed at a predetermined position so that the mold is shifted onto the stationary beam 22 to be positioned thereon.With this arrangement it is possible to enhance the accuracy of the positioning.
