An individual section of a Hartford I. S. type glassware forming machine is modified to provide for in-line, or parallel motion, of the split mold halves at both the blank and blow stations. Vertically extending rock shafts move the blank and blow mold holder structures on fixed ways, through toggle links similar to those in a conventional I. S. machine, but the space formerly occupied by the hinge pin at the blow side is made available for the mold structure because the ways are oriented parallel to and slightly below the neck ring hub mechanism. This design provides for an increased mold closing force at the blank side and simplifies the mold holder structure itself whereby the molds can be continually cooled from an internal chamber in the mold holder which is supplied with cooling air through a vertical interface between the movable mold holder structure and the fixed machine frame. |
