Abstract:
In a method for producing a riser for inserting into a casting mold used for casting metals, the riser includes a riser body ( 31 ) surrounding an inner cavity ( 36 ) as a riser volume and is composed of an exothermic and/or insulating riser material ( 30 ). To produce a single-piece riser body ( 31 ) in a two-part core box ( 10 ), a cavity ( 14 ) reproducing the outer contour of the riser body ( 31 ) is formed and, in order to produce the inner cavity ( 36 ), a reversibly expandable king ( 15 ) is set in the cavity ( 14 ) in such a way that, in the shooting of the riser body ( 31 ), the wall region ( 32 ), the cup region ( 33 ), and the base region ( 34 ) of the riser body are formed by the riser material ( 30 ) introduced into the intermediate space ( 41 ) between the expanded king ( 15 ) and the inner wall ( 40 ) of the cavity ( 14 ).

Claim (Index 13):
A method for producing a singe-piece riser body for inserting into a casting mold used for casting metals, the riser body ( 31 ) surrounding an inner cavity ( 36 ) as a riser volume and composed of an exothermic and/or insulating riser material ( 30 ), wherein a riser opening ( 35 ) is formed in a base region ( 34 ) of the riser body and the inner cavity ( 36 ) has, in at least a partial region, a diameter that is larger than the diameter of the riser opening ( 35 );, comprising the steps of:\n providing a core box ( 10 ) comprising a bottom box ( 11 ) and a top box ( 12 ); forming a cavity ( 14 ) in the core box ( 10 ) that reproduces an outer contour of the riser body ( 31 ); positioning a king ( 15 ) in the cavity ( 14 ) of the core box ( 10 ), wherein an outer contour of the king ( 15 ) is reversibly expandable; expanding the outer contour of the king ( 15 ); producing the inner cavity ( 36 ) in such a way that during shooting of riser material to form the riser body ( 31 ), a wall region ( 32 ), a cap region ( 33 ), and the base region ( 34 ) of the riser body are formed by the riser material ( 30 ) introduced into an intermediate space ( 41 ) between the king ( 15 ) in the expanded state and an inner wall ( 40 ) of the cavity ( 14 ), wherein the riser opening ( 35 ) arranged in the base region ( 34 ) of the riser body ( 31 ) is formed by a foot segment ( 37 ) of the king ( 15 ), the foot segment defining a first diameter, wherein the king ( 15 ) does not protrude beyond the first diameter of the foot segment ( 37 ) in a non-expanded position of the king, such that a completely shot riser body ( 31 ) is removable from the king ( 15 ) through the riser opening ( 35 ) of the riser body during unmolding out of the core box ( 10 ).
