Abstract:
Disclosed are a compensating retaining member for use with a molding system and the molding system incorporating same. A retaining structure (116, 116a, 116b) for use in a molding system, the retaining structure (116, 116a, 116b) configured to cooperate with a slide (112) that is configured to receive, in use, a split mold insert (114) coupled to the slide (112), is provided. The retaining structure (116, 116a, 116b) comprises a body (902, 1002) defining a relief element (904, 1004, 1004a) configured to provide a degree of flexibility to the body (902, 1002).
Abstract:
According to embodiments of the present invention, there are provided a mold stack, a molding system incorporating same and a method of aligning the mold stack. For example, a mold stack (100, 100a) is provided. The mold stack (100, 100a) comprises a first molding cavity defining component (1702), a second molding cavity defining component (1704) and a third molding cavity defining component (1706), with the second molding cavity defining component (1704) being located, in use, in-between the first molding cavity defining component (1702) and the third molding cavity defining component (1706). At least one of the first molding cavity defining component (1702) and the third molding cavity defining component (1706) is associated with a respective compensator (206, 206a, 702), the respective compensator (206, 206a, 702) configured to allow the at least one of the first molding cavity defining component (1702) and the third molding cavity defining component (1706) to align itself relative to the second molding cavity defining component (1704).
Abstract:
Disclosed are a compensating core for use with a molding system and the molding system incorporating same. A core insert (105, 105a, 105b) for use in a molding system is provided. The core insert (105, 105a, 105b) comprises a core base (202, 202a) for defining, in use, a portion of a molding cavity (120); a core support (204, 204a) for supporting, in use, the core base (202, 202a) relative to a core plate of the molding system; a compensator (206, 206a) associated, at least partially, with the core support (204, 204a) to permit at least a degree of axial movement to the core base (202, 202a).
Abstract:
According to embodiments of the present invention, there is provided a split mold insert (116) for a molding system. A first split mold insert (116) complementary to a second split mold insert (118), the first and second split mold inserts (108a, 108b) configured, in use, to form a neck region (304) of a preform (302) capable of being blow-molded. The first split mold insert (116) comprises a top portion (402) and a bottom portion (404); the top portion (402) for abutting, in use, a cavity plate assembly (1106) and the bottom portion (404) being at an opposite extreme relative to the top portion (402); a back portion (408) and a face portion (406) opposite each other, extending between the top and bottom portions, the face portion (406) defining a molding surface defining portion (410) for forming, in use, at least a portion of the neck region (304) of the preform (302); the back portion (408) comprising a connecting interface for connecting, in use, to a slide bar (108).
Abstract:
Disclosed are a compensating mold stack, a molding system incorporating same and a method of aligning the compensating mold stack. A mold stack (100) for use in a molding system is provided. The mold stack (100) comprises at least two compensating components.
Abstract:
According to embodiments of the present invention, there is provided a slide bar (108) for slidably linking a split mold insert (116, 118) to a first mold half of an injection mold for forming a preform (302) capable of being blow-molded into a container. The slide bar (108) comprises a base structure (109a) defining a first slide interface (109b) for linking the base structure to an actuating bar (110,118) of the injection mold; a second slide interface (109c) for receiving the split mold insert (116, 118); a third slide interface (109d) for cooperating with a locking structure of the first mold half (1106) of the injection mold; the second slide interface (109c) and the third slide interface (109d) formed on opposing extremes of the base structure (109a).
