From the above process, it can be seen that the pressure of each section needs to be very consistent and accurate. In actual production, air leakage caused by poor sealing of the holding furnace, changes in the gas supply system, changes in air pressure, theoretical calculations and Actual deviations etc. lead to poor reproducibility of casting parameters
In addition, every time the low-pressure casting is filled, the liquid metal level in the holding furnace will drop a part. Although some equipment continuously adjusts the liquid level compensation pressure through theoretical calculations, the pressure parameters of each section of each casting are different from the actual requirements. deviation

Description
technical field [0001] The invention relates to the field of moulds, in particular to a position sensing control system for the metal liquid level in a casting mould. Background technique [0002] The low-pressure casting process of the casting mold is as follows: through the liquid level pressurization program (parameters such as pressure and time of each section) set by the equipment, the sealed holding furnace is filled with dry compressed air at a certain pressure, and the molten metal in the holding furnace is under pressure. Filling the cavity of the mold through the riser tube, the specific program steps are as follows: six steps of liquid rise, mold filling, crust solidification, pressurization, pressure maintaining, pressure relief and solidification. Liquid lifting is the process of filling a certain pressure in the holding furnace so that the molten metal in the holding furnace rises to the position of the gate through the inner cavity of the liquid lifting tube u...
