Size Variable Casting Mold

Abstract: The present invention provides a size variable casting mold which includes a pair of fixed sides positioned such that the fixed sides face each other at a distance from each other; and a pair of movable sides which is positioned between the fixed sides such that the movable sides may move in the state in which the both end sections thereof are in contact with the fixed sides and has concave portions which are respectively indented on the both end sections wherein molten metal is injected between the fixed sides and the movable sides. The size variable casting mold as above prevents damage to the fixed sides due to friction between the fixed sides and the movable sides and prevents the deep and large expansion of damage even though the damage is generated to the fixed sides so as to extend the lifespan of the mold and the replacement period thereof.
