Patent number: 9370821Abstract: A die cast part of a die casting mold having at least one first component comprising a pressure zone, at least one second component and at least one heat exchange chamber permeated by a fluid and formed by the components for controlling the temperature of the pressure zone. The first component comprises a heat transfer surface integral to at least one wall of the heat exchange chamber and thermally associated with the pressure zone, and the pressure zone bounds at least one region of the gate region. The second component comprises at least one fluid guiding protrusion protruding into the heat transfer chamber and/or a fluid guiding recess open toward the first component. The fluid guiding recess forms at least one portion of the heat exchange chamber and/or the fluid guiding protrusion and/or the fluid guiding recess forms a flow contour surface of the second component in particular adapted to the curve of the heat transfer surface.Type: GrantFiled: May 4, 2011Date of Patent: June 21, 2016Assignees: GEORG FISCHER AUTOMOTIVE (SUZHOU) CO LTD, GEORG FISCHER GMBH & CO KG, GEORG FISCHER DRUCKGUSS GMBH & CO KG, GEORG FISCHER GMBHInventors: Ignaz Huber, Johannes Wunder, Michael Guenzel, Sebastien Nissle
