Cavity-creating tool for foaming operation

摘要

A tool creates a fastener-receiving cavity within a foam-filled structure that includes a panel with a slot for receiving the fastener and foam backing that is cast in place against on the underside of the panel. The tool includes a clip and a plunger. The clip is inserted into the slot and has legs joined by a hinge. The plunger is inserted between the legs to spread the legs and fills the space between the spread-apart legs that would otherwise become filled with foam. After the foam is cast, the plunger is removed so that the legs can be returned to a closely spaced relationship and the clip is removed from the slot, leaving a cavity for subsequently receiving a fastener.
