Abstract:

An insert molding machine has first and second mold sections, one of which is movable between open and closed positions, A slide carrying inserts is movable from an open position to a closed position wherein the slide and first and second mold sections define a mold cavity in which a part is molded. A single direction cam mechanism in the slide engages a pin in the movable mold section to releasably connect the slide and movable mold section during closure. The connection causes the slide to open upon subsequent opening of the movable mold section but allows the slide to be closed independently of the movable mold section.
