Based on this, U.S. patents US6021840, US6070643 and Chinese patent CN102527982A report die-casting equipment for amorphous alloy workpieces. In these technologies, the vacuum channel of the alloy is relatively separated from the melting coil. If it is necessary to increase the vacuum opening, the size of the cavity It will inevitably increase, which will lengthen the time to obtain high vacuum and reduce production efficiency

Provided is an equipment for bulk amorphous alloy high-vacuum die-casting and forming, mainly comprising a high-vacuum pressure chamber, a high-vacuum induction heating system, and a high-vacuum mold system. The equipment is used mainly for fabricating bulk amorphous alloy members, and is capable of performing bulk amorphous alloy member high-vacuum casting and forming under the protection of a high vacuum or an inert gas. The high-vacuum induction heating system uses coaxial electrodes to heat and melt an alloy; heating efficiency is effectively increased, while the system is also organically incorporated with a vacuumization channel; thus the structure of the cavity is simplified, high vacuumization efficiency is achieved, and a high vacuum is created. The invention also relates to a process for bulk amorphous alloy high-vacuum die-casting and forming.
