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.
