PROBLEM TO BE SOLVED: To enhance the degree of freedom in which the positions of a vacuum hole and a heater can be arranged. SOLUTION: This die structure is designed so that a foamed molding process can be performed in such a state that a skin material is spread by vacuum suction over the entire internal surface of a die. In addition, the die structure consists of a base 3 which is made of metal particles and a binder, and is gas- permeable and formed to a specific shape, and a die face member 4 which is supported on the surface of the base 3 and has pores 4 opened through the member 4. Since the base 3 is gas-permeable, the positions of the pores 4 and the heater 30 can be freely selected regardless of the interrelationship between the positions. |
