Abstract
Apparatus for maintaining a diametric uniformity of wall thickness in a hollow molded plastic article by maintaining axial mold alignment over the period of use thereof. Guide blocks are mounted in circumferentially spaced relationship on one of the telescopic mold elements and pockets are provided with wear plates in the opposite element to receive the guide blocks axially therein and to provide a centering maintenance function which overrides the alignment function of other portions of the mold; e.g., tapered telescopic striking surfaces which are internal of the guide and wear block arrangements.
