Ingot mould for quenching metals and ingots thus obtained

Metal ingot mold for manufacture of an ingot by cooling and solidification of a mass of liquid metal, comprising a wall and an opening, the wall defining a bottom and an inside surface having a portion defined as a cooling surface S which can dissipate at least some of the heat energy released by the metal mass during cooling and solidification, the wall comprising at least one shape element that forms at least one interlocking element, stacking element or handling element on the ingot,

• the cooling surface S comprising at least one planar surface element Si forming at least a part of the bottom of the ingot mold, each said planar surface element Si having a planar tangent Pi thereto with at least one point C on tangent Pi such that all straight line segments D connecting any point R on the cooling surface S to point C pass only inside the ingot mold, and the total surface area of the at least one surface element Si being equal to at least 10% of the cooling surface area S.
