  • Patent number: 7125247
    Abstract: A linkage assembly for a multiple level stack mold molding machine having a fixed platen, a movable platen, a plurality of carriage assemblies. The linkage assembly includes an arm on each carriage assembly pivotally connected to a central pivot point on one of the carriage assemblies. An arm also extends between the fixed platen and an end of one of the arms on a carriage assembly. Another arm extends between the movable platen and an end of another of the arms on another of the carriage assemblies. A pair of arms extend between each adjacent carriage assembly, each one of the pair of arms extends from an end of an arm of one carriage assembly to a central pivot point on an adjacent carriage assembly. Each arm of the pair of arms is shaped to extend around a periphery portion of a mold opening to enable full access to the core and cavity plates.

  • Patent number: 7080978
    Abstract: A platen (50) for a molding machine includes an intermediate support structure (20) between two planar walls (16, 18) having ribs (40) arranged at a non-normal angle ? to a first wall (18). The ribs (40) couple forces from the first wall (18) to the second wall (16) in such a way that bending of the second wall (16) is resisted. This adds to the rigidity of the second wall (16) and hence the platen (50), adding to flatness of the arrangement. Gussets (42) may be provided extending between the ribs (40) and the intermediate support structure (20). This has the effect of surrounding and supporting an injection bore (14) and further adding to the coupling of forces to the edge portions of the second wall (16) to resist forces acting to bend the wall.

  • Publication number: 20050287244
    Abstract: A mold carrier (61) contains a fluid distribution system, such as a hot runner system (60), having a nozzle (76) with a substantially flat face (80, 82). The hot runner system includes melt channels (66-70) that require alignment with a complementary melt channel (96) within an interface adaptor, such as a sprue bushing (92), that permits coupling of the hot runner system to a mold (62, 64). The sprue bushing (92) also has a flat sealing surface that is arranged to abut, in use, against the substantially flat face (80, 82) of the nozzle (76) to provide an interface. Under appropriate positive biasing (88), the flat faces of the nozzle (76) and sprue bushing (92) produce a substantially flat interface that maintains sealing contact in the face of potential radial misalignment between the various melt channels. The interface is recessed within a boundary defined by a mold locating ring (100), thereby protecting the nozzle from damage during loading of a mold into the mold carrier (61).

  • Publication number: 20020022068
    Abstract: The technical field of the invention broadly relates to molding systems, and more particularly to a flexible shoe assembly for use in a molding system. The clamp unit of a molding system includes a moving platen and a stationary platen supported by a frame. Tie bars interconnect the moving platen with the stationary platen. The tie bars are secured to the stationary platen and pass through respective openings in the moving platen. Each tie bar is supported and guided within their respective openings by a flexible shoe assembly and wear pad. The flexible shoe assembly has a force redirector for directing force away from a peripheral edge of the wear pad towards a central force area. The flexible shoe assembly also includes a load distributor to distribute the load across the wear pad surface. The flexible shoe assembly includes an upper support that is flexible about a lower support to keep the wear pad in operational contact with the tie bar.

  • Patent number: 6261505
    Abstract: A mechanism for applying a clamping force to a columnar member, such as a tiebar, is described. The clamping mechanism includes a compressible member surrounding the columnar member for gripping the columnar member and transmitting a clamping force thereto, which compressible member is slidable along the columnar member. The mechanism further includes a clamping piston for applying a clamping force, which clamping piston has a bore with an engaging surface for receiving and frictionally engaging the compressible member. The frictional engagement between the compressible member and the engaging surface prevents any relative sliding movement between the compressible member and the clamping piston.

  • Patent number: 6134931
    Abstract: A mold is provided having a mold cavity in the final shape of an article and a hollow article is placed in the mold adjacent the mold cavity. The hollow article is preformed into an intermediate shape by closing the mold around the hollow article, and then formed into the final shape by introducing fluid pressure into the preformed hollow article to conform the preformed hollow article into the shape of the mold cavity.
