Abstract: A manifold for delivering molten plastic material into a mold cavity for forming generally cylindrical parts such as food and beverage containers having large aspect ratios. The manifold includes a manifold block, an inlet, and at least two outlets in fluid communication with the inlet. The outlets are configured for injecting molten plastic material into a single mold cavity in order to ensure that the molten plastic material reaches the outermost portions of the mold cavity prior to setting up. The manifold can also be configured to be attached to a second manifold in place of a single outlet on the second manifold.

Abstract: A three piece nozzle assembly for injecting molten plastic in an injection molding machine carrying out a high pressure, high volume continuous molding process to mold thin walled parts. A nozzle housing has an internally threaded dual diameter bore in one end which receives in one bore portion an externally threaded shank of a nozzle. A sleeve is threaded into the other bore portion and is tightened adjacent to a flange on the nozzle shank to lock the nozzle to the housing and prevent the pressure of the injection molding from working the nozzle loose from the housing. A gap is formed between the sleeve and nozzle shank to reduce the thermal effects.

Abstract: A triple stack mold which is operated by a standard mold press and which presents three molding interfaces. Molten plastic is supplied to all molding cavities in equal amounts through a distribution system that includes manifolds in the mold components which receive the plastic and distribute it through passages leading to the mold cavities. The main passages leading to the manifolds are equipped with special nozzles constructed to compensate for differential thermal expansion of the mold parts.

Abstract: An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centre of the stacked mold block series. The centrally located distribution block is connected, in sealed relation with the injector head, being axially displaceable therefrom in continuing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold interfaces, to preclude drooling of fluid plastic stock upon opening of the molds includes pressure fluid actuators for operating the valves, wherein the pressure fluid may comprise the fluid plastic stock.
