Injection molding tool with nozzle plate and cavity plate connection
A recently granted patent (Publication Number: US11992986B2) discloses an innovative injection molding tool designed to facilitate the flow of melt during the injection molding process. The tool comprises a unique configuration involving a nozzle plate with a first through-hole housing an injection molding nozzle, and a cavity plate with at least one cavity half connected to a second through-hole coaxially aligned with the first through-hole. An essential component of this tool is the nozzle bushing, which encloses the injection molding nozzle and is operatively connected to the cavity plate and/or the nozzle plate through an operative connection means. This connection means includes a flange plate or a threaded bushing fastened to the plates with screws or a threaded connection, ensuring stability and proper alignment of the components.
Furthermore, the patent claims detail additional features of the injection molding tool, such as the arrangement of the operative connection means between the nozzle plate and the cavity plate, the presence of stop surfaces to prevent displacement of the nozzle bushing, and the inclusion of sealing means for effective operation. The tool also incorporates elements like securing means, anti-rotation mechanisms, and coolant channels to enhance functionality and efficiency during the injection molding process. The patent further extends to cover the specific design of the nozzle bushing and operative connection means for use with the injection molding tool, emphasizing the comprehensive protection of the innovative technology disclosed in the patent.
