Abstract

PURPOSE:To improve the efficiency of self-aligning and the separation of burr by previously forming a hole to the drag of the draft die of deburring and shaping a projection to a molding tabular body for the O ring when deburring the O ring. CONSTITUTION:A plurality of the projections 7 are formed previously to the molding tabular body 8 for the O rings. When a plurality of the projections 7 are inserted into the holes 11 of the drag 10 of the draft die of deburring, each O ring product section 3 is positioned onto several concave section 13, and the centers of each O ring product 3 and the centers of respective concave section 13 are conformed accurately. When each convex section 12 of a cope 9 is positioned onto the O ring product sections 3 and the cope 9 is pushed against the drag 10, the product sections 3 for each O ring are separated from bite-off sections 4, and loosely inserted into the concave sections 13. Accordingly, the product sections 3 for the O rings are accurately detached mechanically and rapidly from the tabular body 8.
