ABSTRACT:
A pair of shear steels are carried by companion mold members. Each shear steel including a shearing edge and a sealing rim, is slidable along a path perpendicular to the axis of a blow pin and to the open-close path of the mold members. The shearing edges of the shear steels are aligned with each other and with the blow pin by a locating element of each of the shear steels. Alignment takes place during the closing of the mold members. The locating elements may be discrete elements or the sealing rims may perform the locating function.
