MONOCRYSTALLINE CASTING MOLD

摘要

The invention relates to the field of monocrystalline casting, and in particular to a mold (1) for monocristalline casting comprising at least a molding cavity (7), a starter cavity (10) having at least a first volume (10a) in the form of an upside-down funnel, and a distinct second volume (10b) forming a plinth at the bottom of the first volume and projecting perceptibly relative to said first volume in at least one horizontal direction, a selector channel (9) connecting said starter cavity (10) to said molding cavity (7), and a support rod (20) that is laterally offset relative to said selector channel, and that connects the second volume (10b) of the starter cavity (10) to the molding cavity (7). The invention also provides a casting method using such a mold (1).

主权项

1. A mold for monocrystalline casting, the mold comprising at least:
a molding cavity; a starter cavity having at least:
a first volume in the form of an upside-down funnel; anda distinct second volume forming a plinth at the bottom of the first volume and projecting perceptibly relative to said first volume in at least one horizontal direction to form a lateral projection; and a selector channel connecting said starter cavity to said molding cavity; and a support rod that is laterally offset relative to said selector channel, and that connects the second volume of the starter cavity to the molding cavity.
