摘要： The method relies on the simultaneous filling of mold (1) from its bottom through main casting gutter (3) and rising of molten metal (2) in a secondary gutter (6) which branches off from the start of casting gutter (3), with said molten metal (2) using in secondary gutter (6) in the same amount as in mold (1), so that when the latter is full the main casting gutter (3) is sealed and feeding from the secondary gutter (6) continues, causing it to overflow and fill the corresponding feed head (5) provided on top of mold (1), with secondary gutter (6) communicating at the top with said feed head (5) so that once said feed head is full secondary gutter (6) is sealed. In this manner, the most liquid metal will reach the top part of mold (1) and may be fed to it to compensate contraction of the metal as it cools. A further object of the invention is the device (7) which seals the main casting gutter (3) and the secondary gutter (6), with these two sealing devices (7) being identical and independent.

摘要： The method involves simultaneously filling the mold (1) through its bottom part by means of the main runner (3) while the molten metal (2) rises through a secondary channel (6) branching off from the beginning of the runner (3), said molten metal (2) rising in the secondary channel (6) in the same way as in the mold (1) in such a way that once the mold is filled, the main runner (3) is blocked and feeding of the secondary channel (6) is continued until it overflows and the corresponding sinkhead (5) located above the mold (1) is filled, the secondary channel (6) communicating with the top part of said sinkhead (5) so that once it is filled, the secondary channel (6) is blocked. This makes it possible for the more liquid portion of the metal to reach the top area of the mold (1), post-feeding to the latter being possible to compensate for metal contraction during cooling. The invention also relates to the device (7) that blocks the main runner (3) and the secondary channel (6), both blocking devices (7) being identical and independent.
