20080241309 | Cam System For A Mold - Disclosed herein is a flexible cam system for reducing the likelihood of damage and/or premature wear to components of a mold during use. The flexible cam system accommodates poor coordination between components of an injection molding system during movement of the components. The flexible cam system may include a cam and a cam follower. At least one of the cam and cam follower includes a support structure and an engagement member supported by the support structure. The engagement member defines an engagement surface and includes a compliance member that is operatively connected to at least a portion of the engagement surface to accommodate a force on the engagement surface by the other of the cam and cam follower. | 10-02-2008 |
20080268089 | Mold Assembly Using Inserts - An injection molding machine is provided, including a nozzle assembly having a channel for conveying a fluid. At least one cavity insert is removably mounted within a cavity plate, the at least one cavity insert defining a mold cavity, and a first portion of a gate for communicating the fluid between the nozzle assembly and the mold cavity. A gate insert defines a receptacle for the nozzle assembly, and further defining a second portion of the gate. The gate insert is floatably retained between the nozzle assembly and the at least one cavity insert. Preferably, the gate insert is retained by a gate insert plate that is disposed between the cavity plate and the nozzle assembly. | 10-30-2008 |

For example, the air source device for use with a post-mold treatment device for treating a molded article, the air source device comprising: an air inlet and a refrigerating unit operatively coupled to the air inlet, the refrigerating unit and the air inlet arranged such that air is forced between the air inlet and the refrigerating unit for cooling the air; an air outlet coupled to the refrigerating unit for connecting the refrigerating unit to an air management device of the post-mold treatment device, the air management device configured to direct, in use, cooled air onto a portion of the molded article being treated. | 12-11-2008 |
20090051065 | Method for Post-Mold Treatment of a Molded Article and an Apparatus for Implementing the Method - Embodiments of the present invention teach a method for post-mold treatment of a molded article and an apparatus for implementing the method. For example, a method of post-mold treatment of a molded article is provided. The method can be implemented in a molded article receptacle. The method comprises at a first instance in time, subjecting the molded article to a first type of post-mold treatment; and at a second instance in time, subjecting the molded article to a second type of post-mold treatment. | 02-26-2009 |
20090098232 | Method and Apparatus For Controlling A Vent Gap With Active Material Elements - Method and apparatus for controlling a vent gap in a mold for an injection molding machine are provided, and include an active material insert configured to be regulate the degree of opening of the vent gap. The active material insert is configured to be actuated in response to signals from a controller, so as to selectively block the opening of the vent gap during the molding process. Wiring structure is coupled to the active material insert, and is configured to carry the actuation signals. Melt flow sensors may also be provided to aid in regulating the vent gap, and may be connected to the controller in order to provide real-time closed loop control over the operation of the vent gap. Preferably, the methods and apparatus are used as part of a system for controlling the flow of melt within a mold cavity. | 04-16-2009 |
