MOLD

PROBLEM TO BE SOLVED: To prevent the generation of an inferior product caused by the filling inferiority of a molding material at a time of molding and to easily separate a product and burr by providing connection grooves communicating with each other so as not to become one row in mutually adjacent parallelly arranged escape grooves. SOLUTION: A mold 1 has molding recessed parts 3 for molding cavities on the mutually connected divided surfaces 2 and has inside and outside escape grooves 6, 7 arranged side by side in the diameter direction on inner and outer peripheral sides and connection grooves 8, 9 communicating with each other so that the adjacent escape grooves 6, 7 do not become one row are provided. By this constitution, the molding material protruding from the molding recessed part 3 enhances the filling pressure in the molding recessed part 3 by once stopping the connection grooves 8, 9 in the diameter direction by bonding surfaces 10. Spiral burr is connected by the burr in the diameter direction formed by the connection grooves 8, 9 to be effectively prevented from the entaglement with a molded product.
