Low-pressure casting unit capable of alternately using crucible type heat preservation furnaces

Abstract

A low-pressure casting unit capable of alternately using crucible type heat preservation furnaces, consisting of a low-pressure casting machine, a crucible type heat preservation furnace I, a crucible type heat preservation furnace II, a trolley transfer system, a heat preservation furnace lifting system, a control system, and a transversely moving guide rail, the heat preservation furnace lifting system being arranged at a bottom of the low-pressure casting machine, the heat preservation furnace lifting system lifting the crucible type heat preservation furnace I or the crucible type heat preservation furnace II up and down in the low-pressure casting machine, one side of the low-pressure casting machine being provided with a trolley transfer system in front and the trolley transfer system moving on the transversely moving guide rail. According to the invention, the concept is ingenious, the alternative use of the two crucible type heat preservation furnaces can be realized only by adding a transversely moving guide rail on the outer side of the low-pressure casting machine and adding a transfer trolley. The problem of aluminum slags deposited at the bottom of the crucible type heat preservation furnace is well solved.

1 .
