An evaporation coating device includes a hollow main portion, a loading rack, a source material, and a mask. The loading rack is received in the main portion and mounted on a top plate of the main portion for carrying workpieces to be coated. The source material for evaporation is arranged on a bottom plate of the main portion. The mask is positioned between the loading rack and the source material and includes a mounting rod, two masking plates rotatably mounted on the mounting rod and an adjusting element engaged with the mounting rod and positioned between the two masking plates. The masking plates cooperatively constitute a masking surface and the two masking plates can be rotated by the adjusting element to change the shape of a contour of the masking surface.
