Wedge-lock system for injection molds
Abstract:
A wedge-lock system for injection molds, using a protrusion on one side of the mold and a mating opening and sets of wedges which act together upon mold closing to provide and maintain accurate centering of the core and cavity halves in reference to each other, to prevent core shifts and compensate for uneven thermal expansion of mold components.
