A stone molding apparatus is provided to improve density of stone by reducing porosity of a mixture of raw materials, to reduce a space occupied by facilities for molding stone, and to improve mass-production of the stone. In a stone molding apparatus for molding stone by a stone molding method comprising a mixer process, a storage process, a conveyance process, a vibration process, and a loading process, the stone molding apparatus is characterized in that the vibration process is carried out by a vibration unit continuously applying two or more vibrations with different frequencies to a container in which a raw material-mixture(11) is stored for a predetermined time, and the vibration unit includes a first vibrator(3) applying vibration with a first frequency to the container, a second vibrator(4) applying vibration with a second frequency less than the first frequency to the container after the vibration is generated by the first vibrator, and a third vibrator(5) applying vibration with a third frequency less than the second frequency to the container after the vibration is generated by the second vibrator. The stone molding apparatus comprises a loading unit(7) installed on a lathe(2) and reciprocated along arrangement directions of the vibrators and a loading blocks(8) to load a vibration process-completed container on the loading block. The stone molding apparatus further comprises a pressurization bracket(6) pressurizing the container to put the container storing the raw material-mixture on the first vibrator, and a moving unit for reciprocating the pressurization bracket.
