Patent number: 8865048Abstract: A manifold, in a first pocket, defines a manifold orifice to supply material to a nozzle in a second pocket. A support ring in the second pocket maintains the nozzle stationary within the second pocket. A bushing extends between the pockets, fixedly attached to the manifold and laterally movable with respect to the pockets and the nozzle. At ambient temperature, the centers of the nozzle and manifold orifices are laterally offset from one another, a preload is defined between the nozzle and the bushing, another preload is defined between the manifold and the nozzle, and a gap is defined between the support ring and the pocket. In operation, when the various components thermally expand, the manifold moves laterally within the first pocket, and the nozzle remains substantially stationary within the second pocket, such that the centers of the nozzle and manifold orifices are laterally aligned, and the gap is closed.Type: GrantFiled: December 28, 2012Date of Patent: October 21, 2014Assignee: Injectnotech Inc.Inventor: Vince Ciccone

Publication number: 20100166908Abstract: A crossover nozzle system for transferring molten plastic from an inlet at the center of the stationary platen of an injection machine to the main manifold of the molding chambers of the stack molds of the injection molding machine. The crossover nozzle system relies on molten plastic pressure within the system to actuate the primary sprue shut-off valve, and thus to open and close the flow of molten plastic to the molds. Therefore, a drool-free valve mechanism is created without needing an external actuation of the shut-off valve like, for instance, a hydraulic or a pneumatic cylinder.Type: ApplicationFiled: December 28, 2009Publication date: July 1, 2010Applicant: Injectnotech Inc.Inventors: Vince Ciccone, John M.

Patent number: 7413431Abstract: A series of injection molding nozzle tips having a novel inner insert. The novel inner insert in accordance with the embodiments of the present invention includes a finned profile having flow channels between the finned sections. The finned profile and its associated flow channels cause the flow of molten plastic in the nozzle to go through a breakup into the flow channels before it is merged at the nozzle flow exit. This breaking up of the molten plastic flow and its merging insures a better mixing of the molten plastic and also reduces stresses within the molded part.Type: GrantFiled: June 27, 2006Date of Patent: August 19, 2008Assignee: Injectnotech Inc.Inventor: Vince Ciccone

Patent number: 7291000Abstract: An insert system for an injection mold apparatus is provided. The mold has a mold cavity plate (14) and a mold core plate (12) each secured to mold bases (16, 18), relatively movable between open and closed positions, each having opposing faces, the faces meeting to define a mold cavity between the two faces. At least one of the mold plate faces defines a facial pocket (40) therein for insertion of a mold insert (30). The mold insert is secured to an insert rod (36). The mold plate having the facial pocket (40) defines a passageway (46) extending from the facial pocket through the plate (12) and mold base (16). The insert rod is insertable into the passageway to a position where the insert sits within said facial pocket at a prelock position, where said insert is only partially inserted into said facial pocket. Preferably, the insert is biased in this prelock position.Type: GrantFiled: October 17, 2003Date of Patent: November 6, 2007Assignee: Injectnotech, Inc.Inventors: Vince Ciccone, Petrica Maran
