DIE ASSEMBLY FOR BLOW MOLDING, PROCESS FOR PRODUCING HOLLOW MOLDED ITEM OF RESIN WITH USE OF THE DIE ASSEMBLY, AND HOLLOW MOLDED ITEM OF RESIN PRODUCED BY THE PROCESS

摘要

(Object) To provide a method of manufacturing a resin hollow molded body wherein, predetermined parts can be simply attached when attaching them in the inside of the blow molded hollow body; and the resin hollow molded body, such as a vehicle fuel tank containing a volatile liquid inside thereof, has a good barrier property against a gas component. (Means for solving the problem) There is provided a method for obtaining a product of a hollow molded body characterized in that : a thermoplastic resin parison 6, extruded to a tubular state, is expanded by blow molding; then dies 2, 4 are once divided to assemble predetermined parts 32, 34 inside of the hollow molded body; and the surfaces of the divided dies are joined again.
