ABSTRACT:
A hydraulic impact molding device for molding metal and like materials under instantaneously generated high hydraulic pressure is provided. The device includes a fitted, axially slidable cap which overfits the mold. A generally upward hydraulic force is internally generated within the mold for deforming a workpiece and the impact thereof is substantially absorbed by the slidable overfitting cap thereon which is axially slidably displaced thereby.
