Patent ID: 8899964

Claim:
An edge-gated injection molding apparatus comprising: an injection manifold assembly for distributing a melt stream of moldable material to a plurality of mold cavities of a mold that are aligned on opposing sides of the injection manifold assembly, the injection manifold assembly having a plurality of melt outlets with each melt outlet being in fluid communication with a respective mold cavity of the plurality of mold cavities, and a plurality of nozzle seals for receiving the melt stream from the plurality of melt outlets of the injection manifold assembly and delivering the melt stream to the plurality of mold cavities, wherein each nozzle seal includes a nozzle tip coaxially received within a gate seal and wherein the gate seal includes an inner sealing component threadably coupled within an outer sealing component such that relative rotation therebetween applies a sealing preload between the nozzle seal and a first surface proximate to a respective melt outlet and a second surface surrounding a respective mold gate of a corresponding mold cavity.
