A device for division of a non-Newtonian liquid, for example a molten synthetic material, flowing through a passage (), and comprising a flow-conditioned viscosity decreasing outward in cross section in flow through a T-shaped passage branching (T) deflecting and dividing the liquid flow. In a first embodiment of the device, before the end of the supply passage (), a partition () is installed in the passage branching (T) dividing the liquid counterflow from the supply passage () into two halves, the angular position of the partition () assuming a setting adapted to the distribution of the differentially viscous components of the liquid in the supply passage (). In a second embodiment of the device, in the passage branching (T), a deflector () is installed, so fashioned that essentially the central (viscous) component of the liquid from the supply passage (), prior to its deflection into the discharge passages (), is divided into two components and these are so deflected that the two components preferably flow diametrally towards each other in the region ahead of the discharge passages ().

A gate adapter for use in a hot runner co-injection molding system includes a hollow gate adapter body defining a gate outlet at a free end thereof. At least a pair of nozzle assemblies is disposed in the adapter body, each of nozzle assemblies having an inlet end in fluid communication with a source of liquid extruded material and an outlet end in the adapter body. At least a pair of nozzle passages is formed in the adapter body and extends from the outlet of the nozzle assemblies to a passage outlet adjacent the gate outlet. A valve stem is disposed adjacent each of the passage outlets and is operable to selectively allow flow from the passage outlets to the gate outlet. The nozzle passages extend for a short predetermined distance within the adapter body to minimize heat transfer.

Co-injection nozzle assembly

A shutoff valve mechanism for a plastic injection molding system and process. The shutoff valve mechanism is positioned between the nozzle of the injection molding machine and the hot runner manifold. Force applied by the machine nozzle moves an inner body member in the shutoff valve mechanism and opens a valve allowing molten plastic material to flow through the valve and into the hot runner, sprue bushings, and mold cavities. A biasing mechanism, such as a plurality of spring washer members, returns the inner body member to its rest position, thereby closing the valve mechanism when the machine nozzle is retracted.

Inlet nozzle for hot runner system

Tool insert for the initial cut of a hot-passage nozzle for an injection molding machine, which tool insert () accommodates the anterior (tool side) part of a nozzle and is insertable in turn in a suitably dimensioned recess () of the tool (), which tool insert () consists of an anterior cylindrical fitted part () having a flow passage () and a receiving head () for the tip of the nozzle. At least two cavities (chambers) () separated from each other are present between the outer wall () of the receiving head () of the tool insert () and the wall of the recess () in the tool (), one of which cavities () communicates with the supply passage () for a coolant, present in the tool, and the other cavity communicates with the discharge passage () for the coolant, present in the tool. Also, at least one flow connection is provided between the two cavities (), preferably located as far as possible from the openings of the coolant passages () in the tool.

Tool insert for the gate of a hot-channel nozzle for an injection molding machine, which tool insert connects to the front (tool-side) part of the hot-channel nozzle and in turn is capable of insertion into a corresponding recess of the tool. The tool insert consists of a front cylindrical fitting piece with flow channel and an accommodating head for the nozzle. The accommodating head is provided at its (per se cylindrical) outer surface with one or more projections capable of cutting, which in the radial direction have an extension that is greater than the radius of the accommodating bore provided in the tool for accommodation of the accommodating head of the tool insert. The projections capable of cutting are designed in such a way that, upon insertion of the tool insert into the said accommodating bore of the tool, a guide grooves are cut into the inner surface of the accommodating bore in the tool.
