Research on design and technology of aluminium alloy conductor low pressure casting die

Basic principles of aluminium alloy conductor low pressure casting are introduced in the paper. Casting die design and casting system are respectively introduced aiming at the low-pressure casting process of aluminium alloy conductor, the influence of cylindrical riser tube and cone riser tube on liquid rising pressure and liquid rising stability in liquid rising process are analysed in details. It is concluded that the liquid rising pressure for liquid rising process is relatively low during selection of cone liquid rising, and liquid rising process of cone riser tube is more stable. Therefore, cone riser tube is more suitable for liquid rising process of aluminium alloy conductor low pressure casting than cylindrical riser tube. Low pressure casting technological parameters of aluminium alloy conductors are summarized through analysis on low pressure casting technology, thereby providing reference for low pressure casting technique of aluminium alloy conductors.
