Novel aluminum alloy ingot mould

The utility model discloses a novel aluminum alloy ingot mould, two small -size protruding pieces including inverted trapezoid structure's aluminum alloy ingot mould and interior bottom evenly are provided with 9 blocks of aluminium liquid and hinder stream block in that the aluminum alloy ingot mould is inside, and the both sides limits of two small -size protruding pieces are provided with respectively that two blocks of aluminium liquid hinder stream block, the centre is provided with 5 blocks of aluminium liquid and hinders stream block, 9 height that piece aluminium liquid hinders stream block be three times of height of two small -size protruding pieces, and what 9 blocks of aluminium liquid hindered stream block highly accounts for aluminum alloy ingot mould inside high 23. The utility model discloses on the basis of current aluminum alloy ingot mould, do not change the size of overall arrangement of original ingot casting chain and ingot mould, only increase by 9 and hinder stream block in that the ingot mould is inside, open the effective separation of the inside aluminium liquid of ingot mould for cooling rate increases the intensity of cooling, makes the organizational structure of ingot mould inside even more, refines, and improved the life of ingot mould.
