Key Technology Interpretation

Check valve lip seal for an injection molding machine

PatentWO2006000075A1

Innovation

1. The invention provides a lip seal for a check ring of a check valve, with a groove on the interior circumferential surface of the ring that engages with a surface of the valve to block the flow of injection material into the melt passageway.
2. The invention features a groove formed in the forward face of the ring portion that receives melt, forcing the outer circumferential portion of the ring radially outward to provide a seal between the ring portion and the machine wall.
3. The check valve design is specifically tailored for use in injection molding and die casting machines, addressing the challenges of high temperatures, injection pressures, and corrosive environments.
