Collapsible table formed of injection-molded half-sections

Abstract From the Canadian patent

A system for injection molding a half-section of a collapsible table that includes a pair of interhinged half-sections. The system is provided with a mold, whose dimensions are appropriate to the half-section to be molded therein and , a, driven carrier adjacent one end of the mold having cantilevered therefrom parallel, core rods that project into the mold. When the carrier is driven to cause the core, rods to occupy an "in" position in which the rods are fully within the mold and, extend the full length thereof, molten plastic is then injected into the mold to, submerge the rods therein. When the plastic cures and rigidifies parallel, reinforcing beams are then created about the rods …
