Abstract

The invention discloses a control method and a casting device for aluminum alloy counter-pressure casting, the casting device comprises a casting furnace, a casting upper tank, a crucible, a sealing mechanism and a monitoring mechanism, and the casting furnace and the casting upper tank are connected into a sealed tank body through a detachable mechanism. According to the control method for aluminum alloy counter-pressure casting and the casting device, through the action of the monitoring mechanism, the air pressure in the upper casting tank and the air pressure in the casting furnace can be monitored in real time, and constant-pressure control is set for the upper casting tank through cooperation of the upper tank pressure control mechanism and the pressure measuring mechanism; the lower tank pressure control mechanism and the pressure measuring mechanism are matched to realize set constant pressure control on the casting furnace, so that stable control on the solidification pressure of the upper tank of the differential pressure casting is ensured, the pressure required by the differential pressure casting can be set according to requirements, the stability can be kept, the solidification conditions of castings under different pressures can be improved, and meanwhile, the setting can be realized according to requirements; and the casting precision can be improved.

Description

technical field [0001] The invention relates to the technical field of differential pressure casting, in particular to a control method and casting device for aluminum alloy differential pressure casting. Background technique [0002] Differential pressure casting is also called reverse pressure casting and differential pressure casting. It is a casting method derived on the basis of low-pressure casting. The difference from low-pressure casting is that a sealed cover is placed outside the mold, and compressed gas is filled inside, so that the mold is under a certain pressure of the gas, and the molten metal is filled. When molding, the pressure of the gas in the holding furnace is greater than the pressure of the gas in the mold, and the filling, pressure keeping and pressurization of the molten metal are realized as in low pressure casting, but at this time the casting is crystallized and solidified under the action of higher pressure Therefore, it can guarantee the casti...
