Publication number: 20100196530Abstract: A rotary plate is rotatably supported with respect to a stationary base using an R-guide, and the weight of the rotary plate and a mold mounted to the rotary plate is also supported by the R-guide in addition to a bearing. Therefore, a moment and a vertical downward load acting on the bearing of the rotary plate can be reduced. A block of the R-guide is fixed with respect to the rotary plate side through a disc spring. Therefore, while the rotary plate is rotating, the elastic force of the disc spring causes the rotary plate to separate from the stationary base by a space, which reduces the rotational resistance of the rotary plate. During mold clamping, respective pressure-receiving surfaces of the rotary plate and the stationary base contact each other against the elastic force of the disc spring, which enables reliable transfer of a mold clamping load to the stationary base.Type: ApplicationFiled: July 22, 2008Publication date: August 5, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takeomi Suzumura

Publication number: 20090068303Abstract: A mandrel for providing a tubular article, comprising a supporting structure for the sliding guiding of a side wall constituted by a plurality of plate-shaped elements which can move according to a rule of motion which provides for a forward stroke and a return stroke. The elements are guided in a translational motion by members for the coupling and guiding of the elements with respect to the supporting structure. The mandrel comprises a plurality of actuators which are functionally associated with the plate-shaped elements for the controlled translational motion, along the guided path, of the plate-shaped elements according to presettable rules of motion.Type: ApplicationFiled: May 23, 2008Publication date: March 12, 2009Inventors: Ugo Ferri, Giovanni Fratti

Patent number: 7497678Abstract: A self-positioning clamp piston assembly (300) provides clamp-up, mold break and position reset function through the provision of distinct clamp-up (329), mold break (366) and reset (368) chambers. A position reference shoulder (337) on a piston front ring (330) fixed into a platen (12), permits positioning of a tie bar (12) to ensure clearance (102) between teeth (100) on the tie bar (12) and teeth (98) on a related but separate locking assembly (94). With the tie bar (12) coupled to a clamp piston (304) through a tie bar end plate (340), movement of the tie bar under clamp pressure displaces an independently moveable reset piston (360) from alignment with the tie bar end plate (340). Pressurization of the mold break chamber (366) causes displacement of the reset piston (360) from the shoulder (337), but re-alignment of the reset piston with the tie bar end plate (340).Type: GrantFiled: July 5, 2007Date of Patent: March 3, 2009Assignee: Husky Injection Molding Systems LtdInventors: Pierre Glaesener, Christophe Halter, Joaquim Martins Nogueira

Patent number: 7479247Abstract: A process for casting three-dimensional parts and sacrificial models from casting compounds forced by pressurized inert gas into transparent molds that are supported by transparent mold frames. The casting compound incorporates radiation activated photo initiators which cause polymerization and curing of the compound within the mold. An automated casting system is anticipated which is enabled by the use of very soft, stretchable and deformable material for the mold body and supporting the mold with radiation transparent mold frames. Oxygen and other gases in the atmosphere react with some casting compounds to create a sticky film on mold cavity walls which causes difficulty when removing a casting from a mold. This problem is eliminated by purging the mold cavity with an inert gas between casts.Type: GrantFiled: May 12, 2005Date of Patent: January 20, 2009Inventor: Victor Joyner

Publication number: 20090017151Abstract: An object is to provide a drive apparatus for an injection molding machine which can generate a large thrust force and can provide short-cycled continuous drive. The drive apparatus includes a housing (11); a tubular linear motor (14) including a movable element (12) disposed within the housing (11) in a manner capable of advancing and retreating, and a stationary element (13) attached to the housing (11), the linear motor (14) serving as a first drive section; a member-to-be-driven (15) caused to advance and retreat together with the movable element (12); and a second drive section attached to the housing (11) and disposed such that at least a portion of the second drive section overlaps the linear motor (14) along the axial direction. By merely a slight increase in a radial dimension, the area of a permanent magnet (23) of the movable element (12) can be sufficiently increased, and the capacity of the linear motor (14) can be increased.Type: ApplicationFiled: September 3, 2008Publication date: January 15, 2009Inventors: Takeshi Konno, Yousuke Tokui

Publication number: 20080311238Abstract: A forming die for forming a head on a rope includes a first die block provided with a first die cavity which is provided with at least one first clamping rib, and a second die block provided with a second die cavity which is provided with at least one second clamping rib. Thus, the second clamping rib of the second die block is movable to abut the respective first clamping rib of the first die block to form an annular clamping rib which presses the head of the rope to form an annular clamping groove in a peripheral wall of the head so that the head is fixed on the rope closely by compression of the annular clamping groove to prevent the head from being detached from the rope due to a larger pulling force.Type: ApplicationFiled: January 8, 2008Publication date: December 18, 2008Inventor: Dao-Long Tsai

Publication number: 20080299246Abstract: A mold assembly having a first mold portion with a first cavity having a retention groove. A second mold portion associated with the first mold portion and configured to come together therewith. The second mold portion has a second cavity. The second cavity and the first cavity form a first substrate compartment. A third mold portion is associated with the first mold portion and configured to come together therewith. The third mold portion has a third cavity having a shut-off member. The third cavity and the first cavity form a first over-mold compartment when the first and third mold portions come together. The shut-off member projects from the third cavity surface to impinge on a surface of a component formed by the first substrate compartment. The first retention groove mirrors the shut-off member and is aligned therewith when the first and third cavities form the first over-mold compartment.Type: ApplicationFiled: May 30, 2007Publication date: December 4, 2008Applicant: International Automotive Components Group North America, Inc.Inventors: Roger Catron, Bernard Chan, David Turczynski, Dennis Bunker
