ABSTRACT:
A method for assembling a substantial barrier to the flow of liquid in a circumferentially-extending liquid conduit groove of a mold insert includes forming recesses or undercuts by undercutting the sidewalls of the liquid conduit groove, inserting a plate-like liquid dam within the liquid conduit groove, and clamping the dam in the liquid conduit groove by the use of a pair of locking screws or pins that extend through bores in the dam into engagement with inwardly-facing surfaces of the undercuts. The relationship between the inwardly-facing undercut surfaces and the locking members is preferably such that there is a progressively increasing interfering engagement of the locking members with the undercut surfaces resulting in increasing clamping pressures applied to the dam assemblies.
