Guides and directors position the mold block pairs relative to one another while the assemblies travel along the continuous path. As the holders, and thus the mold block halves, are linearly displaceable from one another, the halves may meet to form the mold tunnel and separate to allow removal of the extruded product.Type: GrantFiled: September 7, 2000Date of Patent: April 13, 2004Inventors: David A. Triplett, Gary Winner, Tom McKeehan, Claude R. Ellis

Patent number: 6652258Abstract: Mold blocks and methods for thermoforming corrugated plastic pipe that provide a uniform vacuum on the internal lateral surface and optimize forced convective cooling on exterior surface is disclosed. Mating mold blocks have an interior surface with transverse corrugations and an exterior lateral surface having transverse channels containing radial slots that intersect circular slits formed in the interior mold surface. The channels are fitted with a dual cover arrangement that serves to provide (1) a low-resistance vacuum path to the slits located on the interior surface and (2) a forced convective heat transfer path to cool the mold blocks. The cover arrangement is removable, providing a convenient means of inspecting, maintaining and modifying the mold blocks.Type: GrantFiled: May 26, 2000Date of Patent: November 25, 2003Inventor: Joseph M. Starita

Patent number: 6644951Abstract: A molding apparatus which is used in a continuous molding operation includes an endless looped track, track carriers which are moved around the track to and from a product shaping mold region and a transfer system for replacement of mold block members used in the apparatus. The transfer system, which operates without interrupting the molding operation includes transfer carriers controlled to move synchronized with the track carriers at a transfer location remote from the mold region and actuators which slide the mold block members between the track carriers and the transfer carriers at the transfer location when the transfer carriers are synchronized with the track carriers.Type: GrantFiled: October 26, 2001Date of Patent: November 11, 2003Inventors: Manfred A. A. Lupke, Stefan A. Lupke

Publication number: 20030151172Abstract: A method for continuously forming discrete hollow parts includes extruding at least one continuous stream of molten plastic. A plurality of mold segments are arranged such that one or more segments periodically close on the one or more streams of molten plastic and define discrete part forming cavities when closed. A pressure differential is created within the discrete part forming cavities to shape the molten plastic accordingly. Air or another gas is replenished within the discrete hollow parts either in the discrete part forming cavities, or nearly immediately upon discharge from the cavities. The discrete hollow parts are then cooled. The apparatus for forming discrete hollow parts in this manner has an extruder and a plurality of the mold segments including one or more segments that can be closed on the plastic stream or streams. The pressure differential is applied by the apparatus to the closed mold segments. The hollow part interior is replenished either by the apparatus or manually by an operator.Type: ApplicationFiled: December 20, 2002Publication date: August 14, 2003Inventors: Greg Floyd, Erik Skov

Publication number: 20030138514Abstract: Pipe molding apparatus having a molding mold tunnel includes an upstream (3) and at least one downstream mold block (7). Each mold block (3, 5, 7) comprises mold block sections which close with one another to form the pipe and which open relative to one another to release the pipe. The mold blocks (3, 5, 7) move downstream of the apparatus together with one another when forming the pipe and move upstream separately from one another when releasing the pipe which cools and shrinks in both diameter and length in the mold tunnel. Each mold block (3, 5, 7) has a hollow pipe forming region with the pipe forming region of the downstream mold block being decreased in both diameter and length relative to the pipe forming region of the upstream mold block (3) to compensate for the plastic shrinkage.Type: ApplicationFiled: October 24, 2002Publication date: July 24, 2003Inventors: Manfred A A Lupke, Stefan A Lupke

Publication number: 20020187215Abstract: An apparatus and method for forming a lenticular optical system is provided in which a composite image is viewable through a molded lens from a first angle and an object or image placed at a preselected distance beneath the composite image is viewable from a second angle. The apparatus of the present invention provides for registration of the lenticular lenses with the printed image when the lenses are formed.Type: ApplicationFiled: March 20, 2002Publication date: December 12, 2002Inventors: Gabriele M. Trapani, Brian Ulricksen
