    Abstract: A hydraulic molding press comprising a main cylinder in which a main ram is mounted for forward and reverse movement and the main ram has a booster cylinder therein into which a hollow stationary booster ram extends. A control valve comprising a valve housing is provided at the end of the main cylinder and the booster ram extends therethrough. The valve housing includes a removable portion called a booster ram cap which threads onto and supports the end of the booster ram. The booster ram cap is detachably secured to the valve housing and the latter is detachably secured to the end of the main cylinder by four studs. A prefill tank connects to the valve housing for supplying prefill fluid to the main cylinder as the main ram is moved rapidly forward by booster fluid supplied through the booster ram from a port in the booster cap. A prefill valve piston slideably mounted in the valve housing is movable to close off prefill fluid flow from the prefill tank. The piston has a central opening through which the booster ram extends. The opening in the piston also serves as a fluid passage for supplying high pressure fluid to the main ram after the piston is moved forward to closed position. Fluid to this passage is supplied through a pair of prefill chambers in the booster ram cap which opens when the prefill pins are moved forward by pilot pressure to close the prefill valve piston. The prefill valve piston is controlled by a two-position remotely operated valve. The prefill pins are continually under pilot pressure. Forward and reverse movement of the main ram is controlled by a three-position remotely operated valve. To effect reverse movement of main ram, the two-position valve operates to decompress the high pressure fluid behind the main ram and opens the prefill valve piston to allow free fluid flow to the prefill tank. Then the three-position valve operates to move the main piston in reverse.

    Abstract: A dual mold clamping apparatus, particularly useful for simultaneously closing two sets of molds and applying additional clamping pressure to one of the sets thereof, having special application in injection blow molding machines. This apparatus comprises mounting means, with extended portions, for the movable halves of each of the mold sets, the extended portions being attached to a common member which moves the movable mold halves in unison in the mold open and mold closed directions. The apparatus further includes selectively engagable means associated with the extended portions of the mold mounting means of one of the mold sets which selectively engagable means is in turn associated with additional mold clamping pressure resistance means and a hydraulic chamber with means for introducing high pressure hydraulic fluid therein for applying additional clamping force pressure through said selectively engagable means both to said additional clamping pressure resistance means and to the movable mold mounting means.

    Abstract: A molding press has hydraulic transporting means for rapidly moving a mold-supporting movable platen toward and away from a fixed mold-supporting platen. A hollow main piston is connected by coupling means with a connecting beam projecting from the movable platen to open and close the mold with great force. Before the transporting means retract the movable platen, the coupling means is withdrawn from the path of the beam so that the beam can enter the hollow piston whereby the length of the machine is reduced.
