Abstract:
1. An injection blow molding device comprising: a lip mold that is designed for a preform and formed of a pair of split molds being clampable; an injection mold that is designed for the preform and fitted on and clamped with the lip mold; a blow mold that is fitted on and clamped with the lip mold; an injection core mold that pierces the lip mold and is located in the injection mold; and a blow core that is inserted into the lip mold, wherein an upper portion of a fitting surface, on which the injection mold and the blow mold are fitted, of the lip mold is formed in a surface tapered downward whereas a lower portion of the outside surface is formed in a vertical surface, wherein an upper portion of a fitting surface, on which the lip mold is fitted, of each of the injection mold and the blow mold is formed in a surface tapered downward whereas a lower portion of the surface is formed in a vertical surface, wherein clamping the lip mold in the injection mold is performed by putting the tapered surfaces formed on the upper portions of the fitting surfaces of both the molds into contact with each other, and wherein clamping the lip mold and the blow mold is performed by putting the vertical surfaces formed on the lower portions of the fitting surfaces of both the molds into contact with each other.
