Abstract: A runner cooling block for use in a die casting system comprises a spreader block, a spreader, a bushing block, a sprue bushing and a water jacket. The sprue bushing comprises a sprue channel running through an interior of the sprue bushing and a cooling channel running circumferentially around an exterior surface of the sprue. The sprue bushing, water jacket and bushing block are assembled to allow cooling water to pass through the cooling channel. The spreader block and the bushing block are assembled such that the spreader is centrally located within the sprue channel wherein molten metal is allowed to pass through the sprue channel for passage into the runner system. The cooling channel includes at least one circumferential heat transfer contour to provide increased heat dissipation to enhance cooling of the molten metal passing through the sprue channel.

Abstract: The present invention is a universal slide assembly for molding or casting systems used to introduce complex designs to moldings and castings, which is cost effective, easy to install, and easy to operate, and includes a base, a slide, and a retention means. The base is directly insertable into a die half for immediate use without requiring the slide to be individually designed or adapted to a particular die half. The retention means provides a means for retaining the slide in a retracted position, preventing the slide from accidentally moving.

Abstract: The present invention is a universal slide assembly for molding or casting systems used to introduce complex designs to moldings and castings, which is cost effective, easy to install, and easy to operate, and includes a base, a slide, and a cam lever. The base is directly insertable into a movable-die half for immediate use without requiring the slide to be individually designed or adapted to a particular movable-die half. The cam lever is capable of moving the slide towards and away from a core without the use of hydraulic power, through cam action.
