Abstract: A spraying apparatus for forming low-melting-point metal mold. The spraying apparatus includes a frame body having a platform. A close space having an operation area is defined above the platform. An adjustment seat having an operation table is arranged on one side of the platform corresponding to the operation area. The adjustment seat is multidirectionally displaceable and 360-degree rotatable and adjustable in angle. A spraying system is mounted on the other side of the platform. The spraying system includes a material-supplying container, a high-pressure pump and a spraying gun. A temperature-controlling box is disposed on a lower side of the frame body. The temperature-controlling box has a power switch, a first-stage temperature control, a second-stage temperature control and a third-stage temperature control which are respectively electrically connected to the material-supplying container, the high-pressure pump and the spraying gun for heating the same to a set temperature.
