ABSTRACT:
A low pressure mold system includes a pouring-in core with a bore which is inserted into the upper part of a foundry mold. The bore is connected by an overflow channel and a drop channel with the hollow space of the mold which is to be filled. Melt is forced from below into the pouring-in channel of the casting mold. The core forms a channel in the shape of a siphon, permitting emptying of the pouring-in channel immediately after the filling process.
