ABSTRACT:
An ice-carving machine comprises a framework, an ice block positioning system, at least one feeding system, and at least one heating mold. The ice block positioning system is fixed on the workbench of the framework for positioning the ice block to be processed. The feeding system drives the heating mold to heat and press the ice block in a mold cavity with a predetermined shape. By the pressure and heat of the heating mold, the ice block is made into the shape identical to the shape of the mold cavity, thus simplifying the process of carving ice blocks, and also saving carving time and cost, being especially suitable for a mass production of ice sculptures.
