Patent number: 6315543Abstract: An injection molding machine includes various devices for reducing injection cycle time. A molded article detection apparatus and method are disclosed. The detection system and method determines if an article, or a portion thereof, remains on a machine core pin after the article ejection cycle has occurred, and, if so, communicates this condition to both the machine controller and the take-out controller. This prevents the machine from starting a new cycle and damaging the injection mold. Also, by communicating the extraction status to both the take-out controller and machine controller, if no articles or portions remain, injection cycle time is reduced. Additionally, a variable vacuum pressure apparatus and method are described. The apparatus and method allows early removal of molded articles from the molds into a take-out plate while the parts are still warm.Type: GrantFiled: May 7, 1999Date of Patent: November 13, 2001Assignee: Husky Injection Molding Systems, Ltd.Inventors: Manfred Lausenhammer, Arnold Mai, Frank Oster, Stephan Klang, Sven Mertes, Witold Neter, Hai Luong, Tiemo Brand

Patent number: 6276922Abstract: The technical field of the invention broadly relates to injection molding systems and more particularly to cooling of a core used in a mold of an injection molding machine. Cooling a core involves supplying coolant through a lengthwise supply tube that extends within a hollow bore formed in the core. The coolant flows through the supply tube, exiting as a stream of fluid at an open end of the supply tube where the stream contacts a substantially perpendicular inner surface of the core. The stream of fluid is initially deflected by this inner surface on an axis perpendicular to an axis of the original flow producing a stagnation zone in the stream having zero or relatively low velocity. The stagnation zone is adjacent to a high heat gate area and results in poor cooling of the core tip. The invention solves the problem of stagnation by application of a fluid velocity inducer.Type: GrantFiled: August 24, 1999Date of Patent: August 21, 2001Assignee: Husky Injection Molding Systems Ltd.Inventors: David Robert Huston, Tiemo Brand, Ali R.
