ABSTRACT:
A method for injection and blow molding products which includes five operations, i.e., injection molding, a temperature control, stretching and blow molding, a secondary working, and releasing operations at respective operating stations. Neck molds of the same number as that of the operating stations intermittently sequentially advance the blow molded product to each station. At the secondary work station, there are provided a reciprocatable injection mold disposed to be movable up and down, a temperature control member, a blow mold and a mechanism for opening and closing the blow mold, 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.
