PURPOSE:To enable saving of installation space of a rotary type blow molding machine, by a method wherein a turning and driving mechanism turning an extruding machine in a horizontal direction to a turntable is provided. CONSTITUTION:An extruding machine 10 is made turntable freely in a horizontal direction to a turntable by a turning and driving mechanism. In the case where a screw 16 of the extruding machine 10 is pulled out for cleaning after completion of blow molding by a rotary type blow molding machine 1, the cleaning of a screw 16 is made easy without interfering an extruding machine main body 13 with a mold clamping device. The extruding machine 10 of the rotary type blow molding machine 1 is provided freely movably vertically centering round a pair of hinges 31, 31 by a vertical driving mechanism. However, the extruding machine 10 is not limited to this and positions of a pair of the hinges may be made almost flush with the height of a die head 19 (on the same plane) through an inverted V-shaped frame. With this construction, vibration of the head 19 or slip of the center of parison 2 can be settled reliably. |
