Problems solved by technology
[0006]The above-mentioned devices do not have the ability to heat the quantitative magnesium melt alone, but only cast the heated magnesium melt in various ways. This single form Defective, the quality of the cast metal is not stable
[0007]For another example, the metal quantitative casting furnaces produced by enterprises now use bracket-type lifting mechanisms to raise the furnace body to achieve the purpose of smooth casting, which will make the operators In the process of operation, maintenance, feeding, and slag removal, the burden is heavier, and the potential safety hazards also increase accordingly

The invention discloses a magnesium and magnesium alloy quantitative casting furnace which comprises a high-capacity crucible outside which a first electric heating component is arranged, wherein the high-capacity crucible communicates with a quantitative furnace outside which a third electric heating component is arranged through a discharge tube outside which a second electric heating component is arranged; a hermetically assembled metal cover plate is arranged on the high-capacity crucible; a one-way air inlet control device penetrates through the metal cover plate; and a pressure release valve for air outlet control is arranged on a sealable furnace cover of the metal cover plate. According to the invention, the magnesium and magnesium alloy quantitative casting furnace and a horizontal cold chamber die casting machine are horizontally placed, and the magnesium and magnesium alloy quantitative casting furnace is filled with inert gases through utilizing the air pressure principle, and the quantitative casting of molten metal is achieved; two furnaces of which one is large and the other is small exert different functions; the large furnace heats molten metal, keeps the temperature, mains the gas pressure, is sealed during the whole process, prevents the molten metal from making contact with the exterior environment, guarantees the metal quality, is provided with the pressure release valve, and has the functions of cleaning convenience and feeding convenience; and the small furnace is used for storing the solution required by quantitative casting per unit, and the capacity is low, so that the solution can be accurately heated to the optimal temperature, and the casting quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of metal casting, in particular to a quantitative casting furnace for magnesium and magnesium alloys, which is especially suitable for automatic pouring of horizontal cold chamber die-casting machines in foundry factories. Background technique [0002] Magnesium and magnesium alloy quantitative casting furnace, as the supporting equipment of horizontal cold chamber die casting machine, must have the technical performance at the same time [0003] The indicators are easy to operate, fast and safe, firm and durable, and reduce costs. Most of the existing quantitative casting devices for magnesium and magnesium alloys use variable frequency motors to rotate impeller pumps to pump out the molten metal; or learn from the ancient method of digging wells to draw water, use a hopper to pull the molten metal in place, and then dump it. into the trough. [0004] For example, the patent application number 20062010052...
