PROBLEM TO BE SOLVED: To obtain a rubber crawler, using comparatively simpler and compact facilities, with regard to a new molding method for the rubber crawler. SOLUTION: This molding method for a rubber crawler 50 uses a rotating barrel-type mold 1 with a cavity shaped like an inner peripheral side part of the rubber crawler 50, formed on the outer surface of the barrel-type mold 1 and an outer mold 3 with a cavity shaped like the outer peripheral side part of the rubber crawler 50, formed on the inner surface. The part shape molding space of the rubber crawler 50 is formed which is sectioned by the outer surface of the barrel-type-mold 1 and the inner surface of the outer mold 3, and the barrel-type mold 1 is equipped with a heat source for heating, while the outer mold 3 has injection holes 10 for filling it with an unvulcanized rubber. In addition, an endless core 5 is tensely installed in the part shape molding space of the rubber crawler 50. Further, the part shape molding space of the rubber crawler 50 is filled with the unvulcanized rubber injected from the injection holes 10 and the unvulcanized rubber is vulcanized while the endless core 5 is incorporated. (1) Barrel-type mold, (3) outer mold, (5) endless core, (8) tension roll, (10) injection holes for unvulcanized rubber, (50) rubber crawler. |
