Description

TECHNICAL FIELD

[0002] In the production and processing of thin-walled titanium alloy components, investment casting is often used, which requires the use of investment casting devices. Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repairing, tree assembling, slurry dipping, wax melting, metal pouring, and post-processing. Specifically, a wax mold of the required casting part is made using wax, and then a refractory material such as clay or binder is applied to the wax mold. The mold is then placed in a baking furnace to melt the wax and obtain a mold shell made of refractory material. The metal blank is then heated and melted in a medium-frequency furnace, and the molten metal is poured into the mold shell using a pouring device. After the metal cools down, the mold shell is knocked down to obtain a thin-walled titanium alloy component.

[0003] The existing pouring device is usually manually held by a worker to scoop out the molten metal from the medium-frequency furnace and pour it into the mold shell. However, the opening of the medium-frequency furnace is extremely hot, and the pouring process is not easy to control when pouring the molten metal manually. As a result, the worker is easily burned and injured, and the safety performance is poor, which is not practical. SUMMARY
