Abstract
A mold-tool system (100) of a runner system (150), the mold-tool system (100) comprising: a manifold extension (102) being configured to couple with a manifold assembly (152) of the runner system (150); and a biasing assembly (106) extending from the manifold extension (102), the biasing assembly (106) being configured to arrange, in use, sealing contact between the manifold extension (102) and a nozzle assembly (156).
Claims8
A mold-tool system (100), comprising:
- a manifold extension (102) being configured to couple with a manifold assembly (152) of a runner system (150);
- and
- a biasing assembly (106) extending from the manifold extension (102) and retaining a nozzle assembly to the manifold extension, the biasing assembly (106) being configured to generate a sealing load between the manifold extension (102) and the nozzle assembly (156), the biasing assembly includes:
- a nozzle collar being configured to receive the nozzle assembly;
- a manifold collar being configured to receive the manifold extension;
- a spring assembly being configured to abut the nozzle collar;
- a locator being received in a receiving groove defined in a side wall of the nozzle assembly;
- and
- a spacer being positioned between the spring assembly and the locator
- wherein:
- the manifold extension defines an extension melt channel being configured, in use, to be in fluid communication with a manifold-melt channel being defined by the manifold assembly;
- the extension melt channel is in fluid communication with a nozzle channel being defined by the nozzle assembly in response to the biasing assembly arranging sealing contact between the manifold extension and the nozzle assembly.

A mold-tool system, comprising:
- a manifold extension being configured to couple with a manifold assembly of a runner system;
- and
- a biasing assembly extending from the manifold extension to retain a nozzle assembly to the manifold extension, the biasing assembly including:
- a manifold collar being configured to contact an extension shoulder of the manifold extension, the extension shoulder being set apart from the manifold assembly, so that at least a part of the manifold collar is placed between the manifold extension and the manifold assembly;
- a nozzle collar being configured to connect with the manifold collar, the nozzle collar extending toward the nozzle assembly;
- a locator being configured to abut a nozzle shoulder of the nozzle assembly, the locator extending toward the nozzle collar;
- and
- a spring assembly being configured for placement between the locator and the nozzle collar.
