a first interface is defined between the external surface and the mounting flange, the first interface for accepting, in use, a sealing member; and
a second interface is defined between the member and the cavity plate, the second interface for accepting, in use, a sealing member.
15. The cavity insert of claim 1 , wherein:
the member includes:
a notch configured to be coupled with a protrusion, complementary to the notch, the protrusion and the notch being configured to positively locate, in use, the cavity insert relative to the cavity plate.
16. The cavity insert of claim 15 , wherein said notch is associated with a first configuration and the protrusion is associated with a second configuration; the first configuration and the second configuration being so selected such that the notch fits securely within, when in use.
17. A mold stack of a molding machine, the mold stack comprising:
a core assembly receivable, in use, in a core plate, the core assembly defining, in use, at least a core portion of a molding cavity;
a gate insert receivable, in use, within a cavity plate having a front face; the gate insert defining, in use, at least a gate portion of the molding cavity;
a neck ring located between the core assembly and a cavity insert, the neck ring configured to define, in use, a neck portion of the molding cavity; and
the cavity insert including:
a body having:
an internal surface defining, in use, at least a body portion of the molding cavity;
an external surface defining, in use, at least a first portion of a cooling channel configured, in use, to direct a flow of coolant; and
a mounting flange configured to support, in use, the body relative to the front face of the cavity plate, the mounting flange including:
a member configured to define, in use, a second portion of the cooling channel, the member further defining a rear mounting extremity, and wherein at least a portion of the first portion of the cooling channel, in use, projects beyond the rear mounting extremity.
18. The mold stack of claim 17 , wherein:
said core assembly includes:
a core for defining, in use, the core portion of the molding cavity; and
a lock ring configured to support, in use, the core relative to the core plate.
19. The mold stack of claim 17 , wherein the neck ring is implemented as a core lock type neck ring.
20. The mold stack of claim 17 , wherein the neck ring is implemented as a cavity lock type neck ring.
21. The mold stack of claim 20 , wherein the neck ring partially defines a support ledge portion of the molding cavity.
