Abstract
PURPOSE:To form facing material having uniform thickness on a pattern made of foam synthetic resin at the optimum thickness by clamping split type metallic mold for forming lost- wax pattern holding the facing material film and packing the synthetic resin foaming material. CONSTITUTION:The facing material is flowed into cavity part 3a from a facing material supplying hose 8 and electrical heater is built in an upper metallic mold for forming lost-wax pattern and a lower metallic mold 2a for forming facing material film and heated and dried for hardening to make the facing material film 3a'. Next, the upper mold 1a for forming facing material film forming the cavity part 3b is clamped with the lower mold 2 for forming pattern and the facing material solution is poured into the cavity part 3b to form the facing material film 3b'. The upper mold 1 and the lower mold 2 forming the facing material films 3a', 3b' are clamped and foaming beads are supplied into the mold from a beads supplying hole 4 to pack in the cavity part 3c. By heating the metallic molds, the foaming beads are foamed and by opening the metallic molds, the formed pattern is taken out. The synthetic resin foaming material at the foaming beads supplying hole 4 is removed and by applying the facing material on the parts 3d, 3d, the lost-wax pattern coating the facing material on the synthetic resin foaming material 3c' at the uniform thickness is obtd.
