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 ).
