Abstract
A mold which can be used for low-pressure casting, in particular, and has at least two mold parts, comprises a feeder channel which is clamped between the two mold parts at an attachment flange thereof, which is parallel to the parting plane of the mold parts. On a side of the feeder channel provided with inlet channels, which lead from the feeder channel to the mold cavity, the attachment flange of the feeder channel is connected to one of the two mold parts in such a way that it seals against the mold, while having an edge area of the flange which is unconnected and can, therefore, expand under the action of heat.
