PURPOSE:To obtain removal work whose productivity is extremely high, by a method wherein actuation performing completely separation and removal of burrs of a molded body by a push-up bar, push-down bar and cut-off mold is performed in order continuously according to a movement of the mold. CONSTITUTION:Molded bodies 6 molded continuously by a rotary blow molding machine 1 are discharged by turning respective head parts toward the front side under a state wherein they are connected with burrs respectively and the molded bodies 6 are supplied to a separating device 2 in order as they are. When a cut-off mold 9a is clamped according to a revolution of the separating device 9b, the burr part between the bottom of the front side molded article fitted and held within a front side separation mold and the burrs 7 which are on a front end side of the molded article is separated from each other by a push-up bar 14 and push-down bar 15 through clamping movement of the mold 9b in the first place and the burrs 7 on the bottom side of the molded material are separated and removed. When the cut-off mold 9b is clamped completely, a cut-off blade 11b of the cut-off mold 9b is come into contact with a cut-off blade rest of a holding mold 9a with pressure and the burrs on the head part of the molded body are cut off. |
