Abstract
A mold half for mounting on a mold holder of a mold open and close mechanism of an I.S. machine. The mold holder includes an insert having a central locating lug on the top thereof and an annular front face. The insert also has an annular upwardly projecting rib, on either side of the lug, the outer surface thereof defining the top portion of the annular front face and inner surface thereof defining the front wall of corresponding annular groove segments. The mold half comprises a blank diameter portion, which can have a dimension within a predetermined dimensional range, to be located adjacent the annular front face of the insert proximate the lug and a two segment annular flange projecting outwardly from the blank diameter portion to be located on either side of the lug. Each of the annular flange segments includes a downwardly projecting annular lip segment for insertion into a corresponding annular groove segment on the insert. An annular upwardly opening annular groove segment adjacent the annular downwardly projecting lip receives a corresponding one of the upwardly projecting ribs, and web portions adjacent the blank diameter portion extend outwardly from the blank diameter portion to define the inner wall of each of the annular upwardly opening groove segments. The web has a dimension that increases progressing away from the lug and which is inversely related to the size of the diameter of the blank diameter portion.
