The present invention relates to a device for preheating molds, capable of improving the binding force of the mold and mold wash by preheating the mold as it is mounted to be compatible regardless of the diameter of an upper mold flask and length of the mold. The device comprises: a first support unit extended in a horizontal direction and formed in a pipe shape; a body in which the upper end is fixated to the lower part of the first support unit, extended to be perpendicular to the lower part of the first support unit, and formed in a pipe shape; a first variation member in which a length can be controlled in a horizontal direction mounted on the upper part of the body and the lower part spread on the upper part of the upper mold flask when the mold is preheated; a second variation member in which a length can be controlled to be perpendicular to the lower part of the body; and a heating coil wound in a spiral shape to the outside of the body and the second variation member and fixated to the second variation member. |
