Abstract (en)
[origin: EP2388087A1] The part (8, 9, 10, 11, 12) of a die casting mold (5, 6, 7) useful in a die casting device (1), comprises a first component (13, 15, 17, 19, 21) having a pressure zone, a second component (14, 16, 18, 20, 22), and a heat exchanging chamber flow-throughable by a liquid, provided for tempering the pressure zone and formed by the components, where the first component has a heat transmission surface belonging to a wall of the heat exchanging chamber and thermally arranged to the pressure zone and the pressure zone limits an area of a sprue area. The part (8, 9, 10, 11, 12) of a die casting mold (5, 6, 7) useful in a die casting device (1), comprises a first component (13, 15, 17, 19, 21) having a pressure zone, a second component (14, 16, 18, 20, 22), and a heat exchanging chamber flow-throughable by a liquid, provided for tempering the pressure zone and formed by the components, where the first component has a heat transmission surface belonging to a wall of the heat exchanging chamber and thermally arranged to the pressure zone and the pressure zone limits an area of a sprue area. The second component has a liquid conductive projection extending into the heat exchanging chamber and/or a liquid conductive recess openly formed towards the first component. The liquid conductive recess forms a portion of the heat exchanging chamber and/or the liquid conductive projection and/or the conductive recess form a flow contour surface adapted to the progression of the heat transmission surface. The shape of the heat exchanging chamber is adapted to the progression of a flowing channel arranged to the sprue area. The liquid conductive recess forms the complete heat exchanging chamber. The liquid conductive recess is formed in the second component in a trough-like manner. The first component is formed in a cover-like manner or a flat-like manner. A recess of the first component area-wisely forms the heat exchanging chamber. The heat exchanging chamber is fluidly connected with a liquid connection formed as liquid conductor, which is provided in the first and/or the second components in an area-wise manner. The first component or the second component has a reception, in which the second component or the first component is completely insertable in an area-wise manner.
