PURPOSE: An apparatus for molding a shell mold core is provided to produce excellent shell mold cores safely and to improve productivity by installing a metal mold injecting resin sand in horizontal state and by making a shell mold core sintered in a metal mold withdrawn outside automatically via a trolley after completing sintering of a shell mold core in a metal mold. CONSTITUTION: A molding apparatus of a shell mold core has a metal mold(13) injecting resin sand in horizontal state. After sintering a shell mold core, a product completed with sintering is withdrawn outside via a trolley automatically. When injecting resin sand to molding grooves formed horizontally, resin sand is filled in the molding grooves uniformly by low pressure thus a product having fine appearance and precise is molded. By injecting resin sand in low pressure, abrasion ratio of a metal mold is reduced and the life of the metal mold is lengthened. From 2 to 3 shell mold cores are sintered at one time by one metal mold. Thereby, productivity is improved remarkably and a danger of an accident is eliminated.
