Abstract
A press for forming complementary parts including mold parts and metal stampings having an articulating frame is disclosed. The press of the present invention comprises a first bolster plate and a second bolster plate which in a first position are spaced apart in a parallel opposed manner. The frame may be articulated from the first position to a second position wherein the bolster plates are in a non parallel, non opposed arrangement. The frame comprises a first pair of spaced apart frame supports pivotally connected at their ends to the first and second bolster plates, and a second pair of spaced apart frame supports having a length less than the first pair of frame supports pivotally connected at their ends to the first and second bolster plates in a spaced apart manner. The pairs of spaced apart frame supports having unequal length, and the bolster plate to which the frames supports are pivoted form a four bar linkage mechanism which allows the bolsters to rotate relative to one another as the frame supports are articulated. A fixed platen and a movable platen are associated with the spaced apart bolster plates with the parts of a separable mold or die affixed to the platen in …
