Title:
【発明の名称】緑砂型内での金属鋳造方法および鋳造通路密封装置
Document Type and Number:
Japanese Patent JP2003512176
Kind Code:
A
Abstract:
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.
