Abstract (en)
[origin: WO2015128180A1] The present invention relates to a method for producing a casting core (10) for manufacturing cylinder heads (100), said method comprising the following steps: - producing at least one core component (20), by a constructive method, with a contour for the formation of internal contours (110) of a first cylinder head (100), - producing at least one further core component (30), by a constructive method, with a contour for the formation of internal contours (110) of a further cylinder head (100), - producing at least one sprue core component (40) for feeding the molten mass during the casting method, - joining the two core components (20, 30) to the sprue core component (40) in an opposing orientation.
