PURPOSE:To provide one stage injection stretch blow molding machine, in which the generation of void, deformation and whitening at a lip part can be prevented from occurring even when the shortening of forming cycle and the re-heating of pre-form after injection molding station are performed. CONSTITUTION:The machine concerned is equipped with at least an injection molding station 10, a stretch blow molding station 12 and a formed article releasing station 14. By circulatingly moving a lip mold 20, which holds the lip part of a pre-form through the respective stations 10, 12 and 14, one cycle of forming process is performed under the condition that the cooling means of the lip mold 20 is provided at the contacting portion of a blow cavity mold with the lip mold in the stretch blow molding station 12. |
