    • 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).
    • 本发明涉及单晶铸造领域,特别涉及一种用于单晶硅铸件的模具(1),其包括至少一个模制腔(7),起始腔(10),其具有至少第一容积(10a) (10b)在第一容积的底部形成底座并相对于所述第一容积在至少一个水平方向上可感知地突出;连接所述起动器腔的选择器通道(9) (10)到所述模制腔(7)和相对于所述选择器通道横向偏移的支撑杆(20),并且将起动器腔(10)的第二容积(10b)连接到模制腔(7) )。 本发明还提供一种使用这种模具(1)的铸造方法。
