Patent number: 7455516Abstract: A horizontal injection molding machine includes two platens, of which one can be a fixed or a moving platen and the other a moving platen, with the platens moving on horizontal columns, and a mold half carrier which is rotatably supported by a turntable and carries mold halves for injection molding tools. A yoke extends between the upper columns for movement along the upper columns. The mold half carrier has on its top side a pivot pin which engages in an opening of the yoke. This arrangement eliminates or at least reduces forces on the columns due to weight and torques.Type: GrantFiled: October 9, 2007Date of Patent: November 25, 2008Assignee: Krauss Maffei GmbHInventors: Bernd Glashagen, Reinhard Holzinger

Publication number: 20080061168Abstract: A spray head for releasing a material made at least of two reactive components includes material supplies for providing two material components and a reciprocating cleaning and control piston Substantially provided in the cleaning and control piston is a mixing chamber which is fluidly connectable to material supplies for receiving and mixing the two material components, when the cleaning and control piston is in a first position. Fluidly connected to the mixing chamber is also a discharge channel for discharging the mixed material components. When the cleaning and control piston is moved to a second position, an air and/or liquid supply is fluidly connected to the mixing chamber so as to allow introduction of purging air or flushing agent to carry out a cleaning process.Type: ApplicationFiled: November 15, 2007Publication date: March 13, 2008Applicant: KRAUSS MAFFEI GMBHInventor: ERNST SCHEIDT

Publication number: 20080065261Abstract: In a method for sequentially programming an injection molding cycle of an injection molding machine comprising one or several injection molds, the injection molding cycle is started manually step by step. The parts of the injection molding machine and/or the parts of the injection mold(s) are manually displaced into the positions or states required for the injection molding cycle in the order required for the injection molding cycle. The movement sequence (the actions and the obtained states) of the machine parts and/or the mold parts is stored in a controller.Type: ApplicationFiled: November 20, 2007Publication date: March 13, 2008Applicant: Krauss Maffei GmbHInventors: Gunther Grimm, Markus Betsche, Dietrich Hunold

Publication number: 20080021678Abstract: A method for providing comprehensive documentation information of complex machines and systems, in particular an injection molding machine is disclosed. Each of the machine components has a storage device that stores information specific for the machine component; in addition, an individual identification is assigned to each of the machine parts. An overall documentation of the machine is generated by combining the component-specific information from a first documentation memory and the part-specific information from a second documentation memory. The overall documentation is displayed on an output device to allow an operator to determine an up-to-date machine configuration and machine state and to intervene in operation and maintenance of the machine.Type: ApplicationFiled: September 18, 2007Publication date: January 24, 2008Applicant: Krauss Maffei GmbHInventors: GUNTHER GRIMM, Markus Betsche, Herbert Pickel

Publication number: 20080012161Abstract: A device and a method are disclosed for producing an optical data medium, in particular high density optical media, such as the recently developed BlueRayâ„¢ disk for illumination with a blue laser (?=405 nm). The required thickness of the data and/or protective layers is of the order of at most several tenths of millimeters. Such thin layers are difficult to produce with conventional injection molding processes. The disclosed device and method solve this problem by overflowing an element placed in a narrow cavity with a low-viscosity material having a viscosity lower than the viscosity of polyurethane, which then forms the data or protective layer, or by bonding a layer produced in this manner to another layer using a low-viscosity adhesive.Type: ApplicationFiled: September 26, 2007Publication date: January 17, 2008Applicant: Krauss Maffei GmbHInventors: Erwin Buerkle, Martin Eichlseder

Publication number: 20080002519Abstract: A mixing head for mixing at least two reactive starting materials includes a feed passageway for introduction of a high-viscosity starting material, and a return passageway for the high-viscosity starting material for allowing circulation of the high-viscosity starting material. The high-viscosity starting material can be introduced into a mixing chamber for subsequent mixing with a via at least one injection port. A switchover device is provided for selectively establishing a flow communication between the feed passageway and the mixing chamber and a flow communication between the feed passageway and the return passageway, wherein the flow communication between the feed passageway and the mixing chamber is provided upstream of the at least one injection port.Type: ApplicationFiled: August 16, 2007Publication date: January 3, 2008Applicant: Krauss Maffei GmbHInventors: WOLFGANG SOECHTIG, Josef Renkl, Ernst Berchtenbreiter
