A casting mold device has an enclosed space (21) between a sprue sleeve (7) and a sprue holder (6).
The enclosed space (21) encloses the outer peripheral surface of the sprue sleeve (7).
The enclosing continues while the sprue sleeve (7) rises to an upper position (U).
The sprue dies are relatively movable laterally with respect to the longitudinal extent of the sprue region, between an advanced position in which the sprue dies form the housing or bush and a retracted relative position.
A curved runner bar (14) having an indexed coping (42) formed at one end thereof is provided in mating relation to the sprue former (36).
In this way, the solidification of the molten metal over the gate (11) is avoided and the reduced quantity of molten metal used per mold improves the economy of the casting process.
In the casting process, the material (8) of the mold (7) is compacted in a region (12) surrounding the runner gate (10) and a depression (13) with a level surface (14) is provided in this region.
