发明名称 HOLLOW-CAST CASTING
摘要 A hollow-cast casting is provided, which includes at least one core opening that is caused by the production technique and which has a closure device that closes the core opening. The closure device can be inserted into the core opening axially in relation to the core opening and provides at least one surface region which, in axial projection in relation to the core opening, can be made to abut a surface region of the casting that is facing toward the casting.
