Digital display control device for gas volume of oil-gas sliding casting disc

The utility model relates to a gas quantity digital display control device for an oil-gas sliding casting disc, which effectively solves the problem that the oil-gas sliding casting disc does not reasonably control gas intake. Comprising a plurality of crystallizers located in a casting disc, oil rings and gas rings are arranged in the crystallizers, annular gas grooves are formed in the gas rings, gas chambers communicated with the gas grooves are arranged in the crystallizers, the gas chambers are communicated with a gas source, and digital display meters communicated with the gas chambers are arranged outside the crystallizers. The crystallizer is simple and ingenious in structure, the gas chamber is arranged in the crystallizer and used for containing a certain amount of gas, gas of a gas source is not directly used for supplying gas to the gas rings, it is guaranteed that the gas amount in each gas ring is sufficient, the gas pressure of output gas is stable, and therefore it is guaranteed that cast ingo
