A self-vibration type continuous casting system comprises a casting machine, a flow dividing device, a molten pool and a self-vibration device. One end of the flow dividing device is connected with the molten pool, and the other end of the flow dividing device is connected with the casting machine; the casting machine comprises a supporting frame, a machine head, a machine tail and a casting portion, wherein the machine head, the machine tail and the casting portion are fixed on the supporting frame; the casting portion comprises a transmission chain; one end of the flow dividing device is connected with the molten pool, and the other end of the flow dividing device is connected with the casting portion; and the self-vibration device is installed below the up transmission chain of the casting portion, and the up transmission chain is vibrated and struck through vibration of the self-vibration device, so that ingot metal in a casting mould of the up transmission chain falls off. According to the self-vibration type continuous casting system, the self-vibration device is installed below the up transmission chain and makes contact with the back surface of the casting mould, and the self-vibration device vibrates and strikes the back surface of the casting mould through self-vibration, so that the ingot metal and the casting mould become loose, and the ingot metal falls off automatically.
