A reciprocating rapid acting high-pressure closure apparatus is described for use in injection molding applications and the like. A closure plate is reciprocatingly mounted for movement towards and away from a high-pressure working region to a frame and is moved by a pair of spaced piston and cylinders located alongside a high-pressure force-producing device. A pair of braces are mounted to respective piston and cylinders which are pivotally mounted to the closure plate. The advance of the closure plate by piston-cylinder action is accompanied by a corresponding swivel action of the braces which are swiveled into positive engagement between the closure plate and the force-producing device when the closure plate has neared the end of its advancing stroke at the working region. At the working region the high-pressure force is actuated to produce a high force through the swiveled brace onto the closure plate. |
