PURPOSE:To provide an injection stretching blow molding machine in which an injection molding cycle time T is used as a molding cycle to increase number of molding forms twice, qualities of the forms are made uniform, and a conveying time margin of the forms is increased to easily convey the forms. CONSTITUTION:A plurality of lip plates for supporting and conveying a plurality of lip molds for holding lip parts of molded forms are simultaneously conveyed in two rows along first-fourth conveying lines 40-44. Two injection molding stations 10a, 10b and a removing station 16 are disposed at the line 40, and a temperature regulating station 12, a blow mold station 14 are provided at a second conveying lien 42. Lip plates are alternately conveyed to the stations 10a, 10b, and the preforms are injection molded by deviating injection molding starting times substantially by (injection molding cycle time T/2). |
