【発明の名称】上向きに充填されるのに適合した鋳造キャビティで金属対象物を鋳造するための方法と装置
Document Type and Number:
Japanese Patent JP3219778
Kind Code:
B2
Abstract:
In casting metal objects in casting cavities (2) in moulds (1), connectable to a pressurized mould-filling furnace (5) through a delivery tube (8) and a connector (9), an external riser (13) is connected to and extends upwardly from the junction of the tube (8) and the connector (9). The riser (13) is used as a temporary reservoir in which the level of molten metal is regulated by controlling the gas pressure in space 7 in the furnace (5) such that the filling head, defined as the difference in level between the metal in the casting cavities (2) and that in the external riser (13), is kept constant or made to vary in a desired manner, e.g. so as to cause the level in the cavities to ascend at a substantially constant rate. The invention makes it inter alia possible to produce high-quality aluminum castings in sand moulds, e.g. using automatic foundry equipment of the DISAMATIC(R) type.
