Title: METHOD AND DEVICE FOR RISING CASTING WITH A SLIDING CLOSURE THAT IS MOUNTED ON THE MOULD FRAME
Abstract:
The invention relates to a method for rising casting/low pressure casting, especially of light metal alloys, comprising the following: a casting furnace which is located under a mould frame (11); a rising pipe and an opening of said rising pipe; a casting mould (41) with an underlying pouring-in opening (44); and a sliding closure (13) which forms a through channel extending longitudinally in an essentially straight line for casting. The sliding closure is closed by means of two immediately adjacent opening sections of the through channel, which are slid against each other crosswise to the longitudinal extension of the through channel immediately after the still-liquid melt has been poured into the pouring-in opening, in such a way that an upper opening section remains openly connected to the pouring-in opening without an undercut and a lower opening section remains openly connected to the opening of the rising pipe, said opening sections being fully offset from each other.
