A blow mold shell assembly (10) includes a mold cavity insert (12) defining a mold profile on an inner surface. A manifold insert (14) is separately formed from the mold cavity insert (12) and disposed outboard of the mold cavity insert. The manifold insert includes at least one coolant channel (22) formed therein. The mold cavity insert is substantially solid throughout its cross-section and precluded from passing coolant. In one example, the coolant channels may be formed longitudinally through the manifold insert. A fluid inlet fitting and a fluid outlet fitting are both in fluid communication with the manifold insert.

La présente invention concerne un ensemble de coque de moule de soufflage qui comprend un insert de cavité de moule définissant un profil de moule sur une surface interne. Un insert de collecteur est formé séparément de l'insert de cavité de moule et disposé à l'extérieur de l'insert de cavité de moule. L'insert de collecteur comprend au moins un canal de refroidissement formé dans celui-ci. L'insert de cavité de moule est essentiellement solide tout au long de sa coupe transversale et écarté du liquide de refroidissement passant. Dans un exemple, les canaux de refroidissement peuvent être formés longitudinalement à travers l'insert de collecteur. Un raccordement d'entrée de fluide et un raccordement de sortie de fluide se trouvent tous les deux en communication fluidique avec l'insert de collecteur.
