Abstract:
A method of using a core rod assembly of an injection molding station of an injection blow molding machine, the method comprising the steps of:providing a sleeve having an outer surface defining an interior surface of an article cavity molded on the core rod assembly, the sleeve also having an interior surface; positioning a mandrel within the sleeve, portions of the mandrel defining a first passageway in the mandrel, the mandrel also having an exterior surface and the first passageway terminating at a port in the exterior surface, the exterior surface cooperating with the interior surface of the sleeve to define a second passageway between the sleeve and the mandrel; operatively coupling an adjustment mechanism between the mandrel and the sleeve; adjustably positioning the mandrel laterally relative to the sleeve via the adjustment mechanism to provide increased coolant flow to one side of the sleeve; and adjustably positioning the port in a radial direction relative to a longitudinal axis of the core rod assembly using the adjustment mechanism.
