Publication number: 20040195712Abstract: Resin or pitch is melted in a melt blender apparatus (11) and then loaded, into a heated jacketed holding tank (12). A pair of feed lines (14, 16) receives resin from the holding tank (12) and feeds an upper gear pump (15) and a lower gear pump (17). A mixing enhancement such as a static mixer (18, 19) is located in each of the feed lines (14, 16) between the gear pumps (15, 17) and the resin delivery ends (25, 26) of the feed lines. The resin-melt feed lines may be equipped with pressure indicators (27, 28, 32, 34) and pressure relief valves (23, 24). The resin-melt feed lines may also be equipped with pump accumulators (31, 33). Resin melt pressure created by the gear pumps (15, 17) forces a piston inside the accumulator back to the desired position. The accumulators (31, 33) can also be used to maintain constant pressure in the feed stock. Resin can be recycled from the accumulators (31, 33) into the melt blender (11).Type: ApplicationFiled: April 4, 2003Publication date: October 7, 2004Inventors: Mark L. La Forest, Christopher S.

Patent number: 6648621Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.Type: GrantFiled: May 29, 2001Date of Patent: November 18, 2003Assignee: Dai Nippon Printing Co., Ltd.Inventors: Shinpei Oono, Kazushi Miyazawa, Keiji Hanamoto, Takashi Tarutani, Takashi Matano, Kazuhisa Kobayashi, Hiroyuki Atake

Publication number: 20020066976Abstract: A method and apparatus for forming golf ball cores with a generally spherical nucleus at its center is characterized by the use of a transfer plate which insures that the nucleus is centered within the core. The core is formed in upper and lower mold plates which contain upper and lower hemispherical cavities, respectively, which are adapted to mate to define a spherical cavity for the core. The transfer plate is arranged between the mold plates and includes a support for the nucleus to position the nucleus in the center of a pair of upper and lower slugs of core material which are molded in the upper and lower hemispherical cavities. When the mold plates are initially brought together with the transfer plate arranged therebetween and with the slugs arranged on opposite sides of the transfer plate, the slugs are partially molded in the hemispherical cavities with the nucleus being pressed into one of the slugs.Type: ApplicationFiled: December 6, 2000Publication date: June 6, 2002Inventors: Mark Cloutier, Jon Wigby, Vincent J.

Publication number: 20020051830Abstract: To provide a moldingl die apparatus wherein simultaneous molding of two or more molded products of different sizes can be carried out. An apparatus for molding of resin products includes a pair of mutually confronting metal dies (30, 50) that are moveable toward and away from each other, molding surfaces or portion (32 (34), 52, (54)) that cooperate in forming mold cavities and resin path (70) that lead injected molten resin from an injection machine to the cavities provided in the metal dies. Two or more cavities C16, C26 of different capacities are provided in the metal dies (30, 50). Simultaneous molding of two or more different resin products (16, 26) with the single molding apparatus increases the production efficiency of the resin products and reduces the production costs. Further, the installation space for the molding equipment, such as the molding apparatus, can be reduced.Type: ApplicationFiled: December 9, 1999Publication date: May 2, 2002Inventors: OSAMI TAKIKAWA, MAKOTO SANO

Publication number: 20020022064Abstract: A method and system for casting a thermoset layer over a golf ball precursor product is disclosed herein. The system includes multiple stations connected by a conveyor system. The thermoset flowable material is dispensed into a plurality of cavities on each of the mold halves. A plurality of golf ball precursor products are then centered and inserted into the first mold half cavities. The mold halves are mated, heated and cooled. Then, at a de-molding station, the mold halves are separated and the thermoset layered golf balls are removed from the second mold half. A preferred thermoset material is a thermoset polyurethane.Type: ApplicationFiled: November 2, 2001Publication date: February 21, 2002Inventors: Gary G. Marshall, Pijush K. Dewanjee

Publication number: 20020022065Abstract: A method and system for inserting a golf ball precursor product into a cavity of a mold half for precision centering is disclosed herein. The precision centering allows for the concentricity of core in relation to the cover of a golf ball. The system includes an insertion mechanism that allows for the vertical movement of a plurality of vacuum cups along a longitudinal pathway. The vacuum cups retain the golf ball precursor products and insert each into a corresponding cavity on a mold half. As the vacuum cups are lowered along the longitudinal pathway, the mold half is elevated along the longitudinal pathway. The mold half and vacuum cups meet at an insertion position where the golf ball precursor products are released from the vacuum cups and set within a thermoset material contained in each of the cavities.Type: ApplicationFiled: November 2, 2001Publication date: February 21, 2002Inventor: Gary G.
