ABSTRACT:
A clamping mechanism for a hot-runner manifold (1) used for injection molding is provided. Screws (11) are used to hold the manifold (1) to a mold plate (7). The screws (11) are attached to clamping members (17) which, in turn, are connected to the manifold. The clamping members (17) include socket portions (21) which are positioned in circular recesses (13) in the manifold. The clamping members (17) can undergo limited pivotal movement due to thermal expansion of the manifold during use.
