Abstract

A casting device and casting method are provided for producing components, in particular cylinder heads. The device includes a reusable steel upper core, which can be lifted off from the component to be produced and which has a movable displacing element. The displacement element can be pressed into the component to be produced for dense feeding. In a method for producing a cylinder head by casting, wherein the steel upper core is used as a substitution for a sand cover core, for dense feeding the displacing element is pressed into the melt that forms the cylinder head in the solidified state.
