  • Patent number: 10160148
    Abstract: A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

  • Publication number: 20140127348
    Abstract: The inventors have researched a problem associated with known molding systems that inadvertently manufacture bad-quality molded articles or parts. After much study, the inventors believe they have arrived at an understanding of the problem and its solution, which are stated below, and the inventors believe this understanding is not known to the public. During operation, the gate orifice and nozzle tip position are fixed. The inventors believe that there appears to be no known mechanism that allows optimization of the tip to gate relationship. Known methods of adjusting position of a nozzle tip, such as shimming between a cavity plate and a manifold plate, or replacing nozzle stack components, may be time consuming and difficult. The known hot runner assembly often must be removed from the molding machine to make the desired adjustments.
