ROTARY BLOW MOLDING DEVICE

摘要

A rotary blow molding apparatus (10) that can produce a large number of heat-resistant containers per unit time while requiring a small installation area includes a primary blow molding rotary section (20) that rotates a plurality of heated primary blow molds (22) while blow-molding and shrinking a primary blow-molded article, a secondary blow molding rotary section (30) that rotates a plurality of secondary blow molds (32) while blow-molding a secondary blow-molded article, and a relay rotary section (40) that is disposed between the primary blow molding rotary section and the secondary blow molding rotary section, and transfers the primary blow-molded article from the primary blow molding rotary section (20) to the secondary blow molding rotary section (30) via at least one first holding section that is mounted on each of a plurality of rotating relay arms (42).
