A fixing device is provided to accurately determine the position failure of a casting material in real time by using a pad unit and a limit unit. A fixing device(50) includes a clamp unit(60), a pad unit(70), and an air limit unit. The clamp unit is used to fix a casting material. The pad unit makes a pad assembly(74) to stick to a reference surface of the casting material. The air limit unit checks the sticking failure between the pad assembly and the casting material. The clamp unit includes a first clamp(62) and a second clamp(64). The first clamp is provided thereon with the casting material. The second clamp is provided on the first clamp while facing the pad unit. The first clamp sets a lower position of the casting material while the casting material is being rested.
