Abstract

The invention discloses an energy-saving environment-friendly low-pressure die-casting machine heat-preserving furnace. The die-casting machine heat-preserving furnace is provided with a furnace body air inlet / outlet hole, wherein the furnace body air inlet / outlet hole communicates with a regenerative chamber, a compressed air switch valve and a compressed air source in sequence through a pipeline; the furnace body air inlet / outlet hole also communicates with the regenerative chamber, an exhaust valve and the atmosphere in sequence through the pipeline; the regenerative chamber comprises a closed housing; a regenerator is arranged in the closed housing; and the closed housing is provided with a hot-end connection hole communicating with the furnace body air inlet / outlet hole, a hole communicating with the compressed air switch valve and a hole communicating with the exhaust valve. The die-casting machine heat-preserving furnace has the characteristics of energy conservation, emission reduction, consumption reduction and the like.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly low-pressure casting machine holding furnace. Background technique [0002] In the current aluminum hydraulic casting process, compressed air is filled into the aluminum liquid holding furnace, and the aluminum is hydraulically injected into the casting mold by using the gas pressure. After the die-casting process is completed, the gas in the holding furnace is released to reduce the pressure in the furnace, so that there is no The molten aluminum entering the mold is returned to the holding furnace for heat preservation, and the die-casting process of a workpiece is completed. Every time a die-casting is completed, the holding furnace is charged and deflated once. During this process, the holding furnace is filled with normal-temperature gas, and the high-temperature gas is released from the holding furnace. The temperature of the high-temperature gas is about 700°C. This will take aw...
