Abstract
A blow mold shell assembly includes a mold cavity insert defining a mold profile on an inner surface. A manifold insert is separately formed from the mold cavity insert and disposed outboard of the mold cavity insert. The manifold insert includes at least one coolant channel 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.
Claims14
A blow mold shell assembly comprising:
- a mold cavity insert defining a mold profile on an inner surface, said mold cavity insert is substantially solid throughout its cross-section and precluded from passing coolant, said mold cavity insert further comprising:
- a removable shoulder insert, a removable body insert, a removable heel insert, and a removable base insert that together form a container profile;
- and
- a manifold insert separately formed from said mold cavity insert, disposed in contact with and outboard of said mold cavity insert, said manifold insert further comprising:
- a plurality of coolant channels defined longitudinally in said manifold insert, said manifold insert defining a single fluid inlet opening to said plurality of coolant channels and a single fluid outlet opening from said plurality of coolant channels.
A blow mold shell assembly comprising:
- a first mold component having a mold profile on an inner surface, the first mold component further comprising:
- a separate removable shoulder insert, a separate removable body insert, a separate removable heel insert, and a separate removable base insert that together form the mold profile, said first mold component substantially solid throughout its cross-section and precluded from passing coolant;
- a second mold component disposed outboard of said first mold component;
- and
- a third mold component movable relative to and disposed intermediate of said first and second mold components, said third mold component including a manifold insert defining a plurality of coolant channels formed longitudinally therein, said manifold insert attached to said second mold component, said first mold component attachable and detachable to said manifold insert, said manifold insert further defining a single fluid inlet opening permitting access into said plurality of coolant channels and a single fluid outlet opening permitting access from said plurality of coolant channels.
A blow mold shell assembly comprising:
- a mold cavity insert defining a mold profile on an inner surface, said mold cavity insert defining a substantially solid cross-section free from coolant channels and further comprising a separate removable shoulder insert, a separate removable body insert, a separate removable heel insert, and a separate removable base insert that together form the mold profile;
- a manifold insert separately formed from said mold cavity insert disposed outboard of said mold cavity insert and having a plurality of coolant channels formed therein, wherein each of said shoulder insert, body insert, and heel insert are attached to said manifold insert with a separate clamp;
- a single first fluid fitting and a single second fluid fitting connected to said manifold insert and adapted, respectively, to deliver fluid to and remove fluid from said manifold insert;
- and
- a holder insert separately formed from and disposed outboard of said manifold insert, said manifold insert attached to said holder insert.
