The invention relates to an auxiliary vacuum die-
casting forming
system. The auxiliary vacuum die-
casting forming
system comprises a pressure chamber, a cavity, a vacuum valve, a gas path vacuum
system and an electrical vacuum system, wherein the vacuum valve and the gas path vacuum system are connected between the pressure chamber and the cavity, and the electrical vacuum system is used for controlling the gas path vacuum system. The electrical vacuum system is provided with a first pressure
transmitter, a second pressure
transmitter, a
vacuum pump, a vacuum tank, a flow distribution
chip and a pneumatic triple piece, wherein the
vacuum pump, the vacuum tank, the flow distribution
chip and the pneumatic triple piece are sequentially connected in series. The first pressure
transmitter, the second pressure transmitter and the
vacuum pump, the vacuum tank, the flow distribution
chip and the pneumatic triple piece which are sequentially connected in series are connected and disconnected with one another through different switches, so that the auxiliary vacuum die-
casting forming system has two different working
modes, namely ordinary die-casting and vacuum die-casting, in this way, the vacuum valve is prevented from being blocked by
molten metal, the quality of products can be improved easily, and production efficiency is improved.
