ABSTRACT:
The present invention provides an injection and blow molding machine which comprises a machine bed having five operating sections, i.e., an injection molding section, a temperature control section, a stretching and blow section, a secondary working and releasing section and a releasing section, a base plate mounted in a peripheral portion above and parallel to said machine bed, a rotary disk rotatably mounted on the under-surface of said base plate and having neck molds of the same number as that of the operating sections, and a drive means fixedly mounted on the central portion of the base plate to intermittently turn the rotary disk with respect to the respective operating sections. It is of course that between the rotary disk and the machine bed, there are provided an injection mold disposed movably up and down, a temperature control member, a blow mold and a mechanism for opening and closing the blow mold, which are disclosed in U.S. Pat. No. 4,105,391, and operating mechanisms similar to an injection mold opening and closing mechanism, a temperature control mechanism, a stretching and blow mechanism and a molded product releasing mechanism on the base plate.
