Core, useful for casting device for casting component e.g. cylinder head of motor vehicle, comprises core elements, and fixing device that comprises first and second fixing units forming undercut in to the relative movement direction

摘要

The casting core (2) comprises a first core element (4), a second core element (6) positioned adjacent to first core element, and a fixing device for restricting a relative movement of the first core element to the second core element in a direction of the relative movement (10). A cylinder head is arranged in the casting core of a casting device. The fixing device comprises first fixing units arranged on the first core element and second fixing units arranged on the second core element. The first and second fixing units form an undercut with respect to the relative movement direction. The casting core (2) comprises a first core element (4), a second core element (6) positioned adjacent to first core element, and a fixing device for restricting a relative movement of the first core element to the second core element in a direction of the relative movement (10). A cylinder head is arranged in the casting core of a casting device. The fixing device comprises first fixing units arranged on the first core element and second fixing units arranged on the second core element. The first and second fixing units form an undercut with respect to the relative movement direction. The second fixing unit comprises a guide and/or a stop for the first fixing unit. The guide moves the first fixing unit in the direction of relative movement, and/or the stop reduces the movement of the first fixing unit in the direction of relative movement. The first fixing unit comprises projection transversely or diagonally extending in the direction of relative movement. The second fixing unit further comprises a recess transversely or diagonally extending relative to the direction of relative movement. The projection and the recess include a mutually complementary shaped portion, and are joined to each other. The first core element and/or the second mole element is formed in a plate shape, and extends parallel to or diagonally in a plane of the plate with respect to relative direction of movement. The first fixing unit further comprises a spacer unit, which extends transversely or diagonally to the projection and has a minimum distance of the first core element defining the second core element. The first fixing unit is positioned at a same side of an edge region or on different side edge portions of the first mole element. The second fixing units are arranged on same side edge regions or on different side edge portions of the second core element. The first core element and/or second core element comprises a sand body, and forms a cooling jacket.
