Integrated investment precision casting device for thin-wall component and casting method of integrated investment precision casting device

The invention discloses a thin-wall component integrated fired mold precision casting device which comprises a U-shaped mounting base and two symmetrical fixed molds arranged on the inner wall of the U-shaped mounting base in a sliding mode. The driving assembly is used for driving the two fixed molds to clamp and fix the investment mold; and the uniform shaking assembly comprises second rotating holes symmetrically formed in the inner walls of the two sides of the U-shaped mounting base, and rotating shafts are rotationally arranged on the inner walls of the two second rotating holes. By arranging the fixed mold, the driving assembly, the shaking-up assembly and the pouring assembly, in the forming process after molten metal is poured into the investment mold, two synchronous motors can be started, and bubbles in the investment mold can be vibrated out and discharged through an exhaust pressure relief valve; therefore, the accuracy of the surface of the thin-wall component after pouring and forming can be ef
