CONSTITUTION: A size variable casting mold comprises the following: a pair of clamped surfaces(100) facing each other; a pair of immobile surfaces(200) with both ends contacting the clamped surfaces, movably located in between the clamped surface; recessed units(211) formed on both ends of each immobile surface, and extended toward one of the edges of the immobile surfaces. Molten metal is inserted in between the clamped surfaces and the immobile surfaces. |
