摘要：The present invention is a method for producing a resin-molded body for ahollow structure having a cavity and an opening connecting the cavity and the outside.The method includes the steps of: creating a hollow core corresponding to the shape ofthe cavity; creating an outer mold corresponding to the external shape of the hollowstructure; setting the core in the outer mold and injecting a fluid of a soft-resin materialinto the space between the outer mold and the core; demolding a soft-resin-moldedbody together with the core from the outer mold after the soft-resin-molded body isformed by curing the soft-resin material, applying an external force to the soft-resin-molded body to deform the soft-resin-molded body so as to break the core intofragments; and discharging the fragments of the core through the opening of the soft-resin-molded body to the outside.
