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. 本发明涉及种用于制造铸造型芯(10)的方法，所述铸造型芯尤其用于金属铸造，所述方法具有以下步骤：a)提供模具，所述模具具有至少个型腔和至少个与所述型腔在流体上连接的填入孔；b)将液态的可硬化的盐造型材料通过所述填入孔装入到所述型腔中；c)使装入到所述型腔中的盐造型材料至少部分地硬化，所述至少部分地硬化在形成由硬化的盐造型材料制成的空心体(12)的情况下进行，所述空心体具有所述铸造型芯(10)的至少个由硬化的盐造型材料限定的空心室(16)，其中，将所述铸造型芯(10)的空心室(16)在所有侧都借助于装入到所述型腔中的盐造型材料封闭。
