Abstract
On the sizing unit of a blow molding machine, one or more blow mandrels are mounted in blow mandrel holders and are centered in sizing plate openings. To obtain faster and more accurate centering, the blow mandrel holder has independently adjustable sleeve and flange parts. The sleeve adjusts axial location while the flange fixes radial location. Conical mandrel tips and sizing plate openings facilitate rapid alignment as the blow mandrels are lowered.
Claims32
