Abstract

The invention relates to a die cast part (8, 9, 10, 11, 12) of a die casting mold (5, 6, 7), having at least one first component (13, 15, 17, 19, 21) comprising a pressure zone (24, 25, 40, 60), at least one second component (14, 16, 18, 20, 22) and at least one heat exchange chamber (27, 36, 43, 51, 55, 62) permeated by a fluid and formed by the components (13, 14, 15, 16, 17, 18, 19, 20, 21, 22) for controlling the temperature of the pressure zone (24, 25, 40, 60), wherein the first component (13, 15, 17, 19, 21) comprises a heat transfer surface (34, 41, 61) integral to at least one wall of the heat exchange chamber (27, 36, 43, 51, 55, 62) and thermally associated with the pressure zone (24, 25, 40, 60), and the pressure zone (24, 25, 40, 60) bounds at least one part of a casting inlet (59). The second component (14, 16, 18, 20, 22) comprises at least one fluid guiding protrusion (64) protruding into the heat transfer chamber (27, 36, 43, 51, 55, 62) and/or a fluid guiding recess (26, 49) open toward the first component (13, 15, 17, 19, 21), wherein the fluid guiding recess (26, 49) forms at least one portion of the heat exchange chamber (27, 36, 43, 51, 55, 62) and/or the fluid guiding protrusion (64) and/or the fluid guiding recess (24, 49) form or forms a flow contour surface (65) of the second component (14, 16, 18, 20, 22) in particular adapted to the curve of the heat transfer surface (34, 41, 61), and wherein a recess (35, 50, 75, 76) of the first component (13, 15, 17, 19, 21) forms at least regions of the heat exchange chamber (27, 36, 43, 51, 55, 62). The invention further relates to a die casting device (1).
