Latest Patents
Among his latest patents is the "Quick Change Mold Tooling." This invention features a mold core assembly designed for removable installation in a molding machine. It includes a first lock element attached to a core and a second lock element that is movably attached to a core retainer. The second lock element can shift between a locked position, where it connects with the first lock element, and an unlocked position, where it is separated. A slip ring surrounds the first lock element, engaging and holding the second lock element in its locked position. Additionally, a spring connects the core retainer and the slip ring, opposing movement away from the locked position, ensuring that the core remains securely in place.
Another significant patent is the "Conduit for Flexible Hot Manifold Assembly for Injection Molding Machines." This manifold assembly supplies plastic material from a source to a mold assembly in an injection molding machine. It features a flexible manifold with an interior conduit that connects the plastic source to the mold assembly. The design includes an input connector, two curved segments, and an output connector, creating a generally S-shaped configuration. This flexibility allows the manifold to adapt to temperature changes, maintaining a stable position between the input and output connectors, thus preventing thermally induced movement during the injection process.
