A device for producing a block of solidified carbon dioxide essentially comprising a high pressure vessel of liquidified carbon dioxide, a thermally insulated high pressure feed tube and a molding box in which a product of solidified carbon dioxide is molded in the form of block, wherein the molding box contains a single molding chamber in a cubic structure which consists of a top cover, a pair of first side walls, a pair of second side walls and a base board, each of which members is designed so as to be easily assembled or disassembled, said first and/or second side walls being formed with a plurality of openings through which gaseous medium flows and being provided with a layer of filter fixedly secured to the inner wall thereof respectively. The base board and the second side walls are formed with engagement grooves for allowing the first and second side walls and base board to be easily assembled or disassembled. Further locking means are provided for ensuring tight locking of the molding box. In an alternative embodiment the molding box may contain a plurality of molding chambers of which number correspond to that of blocks of solidified carbon dioxide to be produced. Liquidified carbon dioxide is delivered to a common distributor via the high pressure feed tube and then distributed to each molding chamber through a lever operated pressure reducing valve and nozzle means.
