The invention relates to a casting device of a double linkage-die zinc beeline ingot-casting machine. A zinc discharging hole is cut at the bottom of a zinc smelter. Zinc liquid is collected through a downward suspension launder and a zinc liquid distributing disk of a turntable style casting device without contact. The zinc smelter is in sealed state. The turntable style casting device drives the distributing disk on which zinc liquid casting distribution nozzles are equally arranged in a radial direction to revolve through a chain-wheel transmission device, so as to realize the synchronous operation of casting operation and ingot mold running. The invention changes liquid-collecting from a zinc liquid surface of the traditional scoop ration casting mechanism and also displaces a motor and a transmission system of the prior scoop ration casting mechanism. Therefore, the equipment structure is simplified and the equipment failure becomes less, with high reliability, reduced maintenance cost. The zinc liquid is collected in sealed state so as to reduce slag rate and enhance the product quality.
