Integrated high-temperature alloy pressure regulating precision casting device

The invention provides an integrated high-temperature alloy pressure regulating precision casting device. The device comprises a temperature control system, a pressure regulating furnace and a pressure regulating gas line control system, and the temperature control system comprises a pressure regulating in-furnace temperature measuring system, a resistor heating system and an intermediate-frequency induction heating system, wherein the resistor heating system and the pressure regulating in-furnace temperature measuring system are used for preheating a liquid lifting pipe and a profile shell, and the intermediate-frequency induction heating system is used for melting alloy. The pressure regulating furnace is composed of an upper tank, a lower tank and a middle separation plate. One end of the pressure regulating gas line control system is connected with vent holes of the upper tank and the lower tank of the pressure regulating furnace, the other end of the pressure regulating gas line control system is connected with a vacuum system and an inertia gas source in sequence, and the pressure regulating gas line control system is used for controlling the vacuum degree and pressure in the pressure regulating furnace. According to the integrated high-temperature alloy pressure regulating precision casting device, the whole pressure regulating casting process can be carried out in vacuum, the possibility of alloy oxidization is reduced, near net forming casting is achieved, and the filling capacity of a thin-wall casting can be improved obviously.
