PROBLEM TO BE SOLVED: To provide a mold apparatus for resin molding having a new energy-saving structure, despite its simple structure, capable of downsizing steam chambers to easily heat a mold, and shortening a molding cycle time.SOLUTION: A first steam chamber is provided between a rear face side of a male mold 35 and a base 301 of a first plate, and a second steam chamber is provided between a rear face side of a female mold 25 and a frame 21 of a second plate. By filling a molding space formed between a front face side of the male mold 35 and a front face side of the female mold 25 with a foamable resin and feeding superheated steam into the first steam chamber S31 and the second steam chamber S21, the mold apparatus heat-fuses the foamable resin in the molding space, and molds a resin molding 200. A flow passage 304 through which the superheated steam is fed into the first steam chamber S31 is provided along the base 301 of the first plate, and the flow passage 304 is arranged across the plurality of male molds 35.SELECTED DRAWING: Figure 2 |
