ABSTRACT:
A pair of generally vertically aligned press bending molds are slidably mounted relative to each other. An alignment pin extends into alignment holes in the upper and lower molds when the molds are vertically aligned. Adjusting screws positioned around the periphery of each mold, contact and bias each mold in a desired direction so as to precisely align the upper mold relative to the lower mold.
