Abstract
Disclosed are a compensating core for use with a molding system and the molding system incorporating same. A core insert for use in a molding system is provided. The core insert comprises a core base for defining, in use, a portion of a molding cavity; a core support for supporting, in use, the core base relative to a core plate of the molding system; a compensator associated, at least partially, with the core support to permit at least a degree of axial movement to the core base.
Claims52
A core insert for use in a molding system, the core insert comprising:
- a core base for defining, in use, a portion of a molding cavity;
- a core support for supporting, in use, said core base relative to a core plate of the molding system;
- a compensator associated, at least partially, with said core support to permit at least a degree of axial movement to said core base.
A sliding interface defined, in use, between:
- a core base for defining, in use, a portion of a molding cavity;
- and
- a core support for supporting said core base relative to a core plate of a molding system;
- said core base and said core support constituting to a core insert, said sliding interface configured to permit a degree of lateral movement to said core base.
A compensating portion defined in a core support used for supporting a core base relative to a core plate of a molding system;
- the compensating portion configured to permit a degree of axial movement to said core base.
A compensator comprising one of:
- (a) a sliding interface defined, in use, between (i) a core base for defining, in use, a portion of a molding cavity;
- and (ii) a core support for supporting the core base relative to a core plate of a molding system;
- the core base and the core support constituting to a core insert;
- and a compensating portion defined in said core support;
- and
- (b) a spring connection disposed between said core base and said core support;
- said compensator for affording, in use, at least a degree of axial movement to a said core base.
A mold stack, comprising:
- a compensating core insert complementary to a cavity insert, the compensating core insert and the cavity insert configured to jointly define, in use, at least a portion of a molding cavity, the compensating core insert configured to have a degree of axial and lateral movement relative to at least the cavity insert.
A core insert for use in a molding system, the core insert comprising:
- a core base having a cavity defining portion for defining, in use, a portion of a molding cavity;
- a core support that is configured to cooperate with a base portion of the core base;
- a compensator associated, at least partially, with said core support to permit at least a degree of axial movement to said core base.
A core support that is configured to cooperate with a base portion of a core base, the core support comprising:
- a compensator to permit a degree of flexibility to said core support whereby to permit at least a degree of axial movement to the core base.
A core base comprising:
- a cavity defining portion configured to define, in use, a portion of a molding cavity;
- a base portion configured to cooperate, in use, with a core support, a portion of the base portion being configured to define, in use, a portion of a sliding interface between the core base and the core support.
A retaining member for coupling, in use, a core base to a core support, the core base and the core support for use with a molding system, the retaining member comprising:
- a first end and a second end, each of said first end and said second end comprising a respective plurality of fingers;
- said respective plurality of fingers is actuatable between (i) a retracted position, where said respective plurality of fingers are insertable, respectively, into a first internal bore and a second internal bore associated, respectively, with the core support and the core base;
- and (b) an expanded position, where said respective plurality of fingers engage, respectively) a first retaining lip and a second retaining lip, associated, respectively, with the first internal bore and the second internal bore.
