Abstract
The invention relates to a process of and an apparatus for injection molding hollow-blown plastic bodies in which a mold cavity formed by a tool and consisting of at least one main mold cavity and one side mold cavity is filled with a pressurized flowable plastic melt and, after the setting in of the hardening of the plastic melt at the walls of the mold cavity, a pressurized fluid is introduced into the main mold cavity, and, with this, the flowable core of the plastic melt is forced out of this main mold cavity, and subsequently, a pressurized fluid is introduced into the side mold cavity by means of which the flowable core of the plastic melt is forced out of the side mold cavity into the main mold cavity, where the material still capable of flowing is deposited on the already hardened walls in the main mold cavity.
