HOT PRESS MOLDING FACILITY

PROBLEM TO BE SOLVED: To achieve simplification, reduce the costs, and improve the productivity for a hot press molding facility capable of preventing oxidation of a steel plate.SOLUTION: A hot press molding facility comprises: a heater 20 which heats a steel plate W1; a press mold 11 composed of multiple molds 11a to 11d which may be opened and closed; a seal member 40 which contacts with both of the opened molds (for example, the fixed mold 11 and the first movable mold 11b) and covers an outer peripheral opening of a mold open space S1 formed between the molds; and a gas supply part 50 which supplies an inactive gas to the mold open space S1. The mold open space S1 is sealed by a lower end surface of the heater 20 and the seal member 40.
