description PROBLEM TO BE SOLVED: To provide a mold having an even number of four or more recessed parts (cavities) and capable of efficiently manufacturing the toe box of safety shoes excellent in uniform quality and strength even if slightly different amounts of a resin raw material are supplied to a plurality of the recessed parts, and a method for manufacturing the toe box of the safety shoes. SOLUTION: In the mold for molding the toe box having a female mold equipped with recessed parts having the inner surfaces each coinciding with the outer surface shape of the toe box of the safety shoes, a male mold equipped with the projected parts having outer surfaces each coinciding with the inner surface shape of the toe box and knock pins for demolding the molded toe boxes, the knock pins are constituted so as to fall or rise by pressure at the time of molding. The method for manufacturing the toe box using the mold is also disclosed.
