<p>A positioning device aligns first and second mold segments moving from an opened position to a closed position. The device includes a female member for connecting to one of the mold segments and for receiving a male member connected to the other of the mold segments. A bearing mechanism is coupled to the female member for receiving the male member and reducing friction between the male member and the female member. One of the female member and the bearing mechanism includes a post extending transversely to the alignment axis and the other of the female member and the bearing mechanism defines a groove receiving the post as the bearing mechanism moves relative to the female member. The engagement between the groove and the post retains the bearing mechanism in the female member when the first and second mold segments move between the opened and closed positions.</p> |
