<p>PURPOSE:To simply, accurately position various molds, a temperature regulating mold, etc., to effectively center a preform, and to prevent a temperature irregularity of the preform at the time of temperature regulating. CONSTITUTION:The injection stretching blow molding machine comprises an injection molding station 10, a temperature regulating station 12, a stretching blow molding station 14 and an injecting station 16. A lip mold 22 for holding a lip of a preform is circularly moved to the stations 10, 12, 14, 16 to execute one cycle of molding steps. In this case, a lip mold supporting plate 20 for supporting the mold 22 is connected to a lip mold transfer plate 18 for transferring the plate 20 to the stations 10, 12, 14, 16 by engaging a positioning hole 34 of the plate 20 with positioning pins 36 provided at a predetermined interval at the plate 18 to position the plate 20.</p> |
