Publication number: 20110233238Abstract: A nozzle body defines an upstream channel. A downstream bracing portion has a lateral bore. A nozzle tip extends laterally through the lateral bore of the bracing portion and has a sealing surface for engaging a gate component that defines a mold gate. The runnerless nozzle further includes a securing component inserted into the bracing portion to hold the nozzle tip against the bracing portion. The bracing portion or the securing component defines a lateral channel in communication with the upstream channel for delivering molding material to the nozzle tip. The nozzle tip can be removed by removing the securing component.Type: ApplicationFiled: June 10, 2011Publication date: September 29, 2011Applicant: MOLD-MASTERS (2007) LIMITEDInventor: Bruce Catoen

Patent number: 7972132Abstract: A valve gated hot runner nozzle with at least two transition members made of different materials located between a nozzle tip and a mold gate component to provide a thermal transition region. A first transition member in contact with the nozzle tip is less thermally conductive than a second transition member in contact with the mold gate component. The valve pin when in the closed position makes sealing contact with at least the second transition member such that cooling from the mold gate component is transferred to the valve pin to cool the melt in the mold gate area.Type: GrantFiled: October 2, 2009Date of Patent: July 5, 2011Assignee: Mold-Masters (2007) LtdInventors: Peter Klobucar, Denis Babin, Bruce Catoen, Scott Gammon

Publication number: 20100159062Abstract: An injection molding apparatus includes a manifold defining a manifold channel for receiving pressurized molding material from an upstream source and a nozzle defining a nozzle channel in communication with the manifold channel to define a flow channel. The nozzle is associated with a mold gate of a mold cavity and delivers molding material to the mold gate. A vane, such as that of an impeller or screw, is rotatably disposed in the flow channel upstream of a mold gate. A motor is coupled to the vane and rotates the vane in either direction. Rotation of the impeller or screw can be automatically adjusted by a controller and a sensor that measures pressure, temperature, or other property of the molding material.Type: ApplicationFiled: December 18, 2009Publication date: June 24, 2010Applicant: MOLD-MASTERS (2007) LIMITEDInventors: Peter Klobucar, Bruce Catoen, Rhonda Goslinski

Patent number: 6634877Abstract: An injection molding machine for forming a multi-layer plastic article by over molding where the second layer of the article includes a portion having a different geometrical profile than the first. The injection mold machine comprises an array of one or more cores which engage arrays of one or more first cavity and arrays of one or more composite cavities. Each composite cavity is formed from the combination of a second cavity and a cavity extension which carries at least a portion of the different geometrical profile. In one embodiment, the cavity extension comprises a pair of cavity portions which are mounted adjacent the core to laterally moveable slides on a movable platen. In another embodiment, the cavity extension is a single element which is moved between a disengaged position wherein the core can be inserted into the first cavity and an engaged position wherein the core is inserted into the composite cavity.Type: GrantFiled: October 5, 2001Date of Patent: October 21, 2003Assignee: Husky Injection Molding Systems, Ltd.Inventors: Robert Sicilia, Robert Schad, Tom Mcginley, Doug Hietkamp, Bruce Catoen

Patent number: 6540496Abstract: A shooting pot actuator for an injection molding machine having two plates carrying pusher rods for pushing against injection plungers within the shooting pots. The plates are mounted outside the mold and the clamp unit, and the pushers extend through bores in the stationary platen of the clamp unit to reach the injection plungers. The actuator reduces the cost and complication of mold design and production, and permits simplified adjustment of the injection plunger stroke.Type: GrantFiled: June 28, 2000Date of Patent: April 1, 2003Assignee: Husky Injection Molding Systems Ltd.Inventors: Robert Schad, Robert Sicilia, Ronald Ing, Bruce Catoen, Robert Domodossola
