Application of plastic bead to join folding or collapsible car hood components employs mold with inclined inlet to bead cavity, inducing turbulence for improved coverage

摘要

Casting resin is supplied to the mold cavity (23) at an angle ( alpha ), and remotely from the plane and surface of the hood sections (10, 11). An Independent claim is included for the mold used to make the application This has recesses enclosing the sections to be joined and forming the bead. The angled injection channel (22) is also included. Variants of this mold and a hood made as described are also claimed. Preferred features: A similar process joins two sections of the hood. The angle ( alpha ) is about 30 deg -90 deg . A similar process is used with a flat pane in the hood. The resin is injected in a region between sections. In the mold, the supply channel is located such that resin enters between the sections to be joined. The hood is flexible and the mold halves have guides locating its edges for the injection process.
