Zusammenfassung:	PURPOSE: A hot mold used for a one-axis and two-stepped press is provided to fabricate panels or plates having a complex structure formed with a plurality of ribs by performing a pressing process. CONSTITUTION: A hot mold includes an upper mold(50) operated by means of an upper piston rod and a lower mold(60) operated by means of a lower piston rod(60). The upper mold(50) consists of an inner mold part(54), which is cooperated with a first piston rod and formed at an outer peripheral portion thereof with a flange section(54a), and an outer mold part(52), which is cooperated with a second piston rod and formed at an inner portion of an opening thereof with a stepped jaw(52a) coupled to the flange section(54a). Heaters(56a,56b,66) are accommodated in the upper and lower molds(50,60). The lower mold(60) consists of an inner mold part(64) cooperated with a lower cylinder and an outer mold part(62) formed at an outer portion of the inner mold part(64).
