When an electric arc is generated in the cavity, high temperature can be conducted to the sealing wax block through the heat conduction rod, so that the sealing wax block is rapidly melted under the action of the high temperature, and at the moment, inert gas filled in the gas tank is rapidly discharged into the cavity through the exhaust nozzle for arc extinguishing; the problem that inert gas is easy to leak and inconvenient for users to use because the inert gas is directly filled in the junction box in the prior art is avoided.

The utility model discloses a combined hollow wax discharge head for investment casting, and relates to the technical field of investment casting. The combined hollow wax discharge head for investment casting comprises a wax piece arranged on the inner side of a shell, and a lower wax discharge head arranged on the inner side of the shell. The lower wax discharge head is located on the outer wall of the wax piece, and the wax piece and the lower wax discharge head are both medium-temperature wax. The lower wax discharge head and the upper wax discharge head adopt a hollow structure, which greatly increases the heating area. The combined design of the lower wax discharge head and the upper wax discharge head is matched with wax materials with different melting points. When the wax is removed, the low-temperature invasion sealing wax melts first, and quickly opens part of the wax discharge channel. Then, the upper and lower wax discharge heads with the hollow structure melt faster than the wax piece due to the larger heating area. Before the wax piece starts to melt, a complete and unblocked wax discharge path is formed. This design greatly speeds up the wax discharge, effectively shortens the wax removal time, speeds up the production cycle, and reduces the risk of shell cracking.
