摘要： The present invention relates to a non-return valve that can be configured for use anywhere along a molding material flow path in a molding system. The non-return valve of the present invention includes an improved means to restrict the backflow of melt therethrough during injection. In particular, a spigot-seal is configurable, during injection, between overlapping, closely-spaced, and mutually parallel complementary male and female spigot portions that are configured between complementary valve members. The spigot-seal advantageously maintains an effective backflow restriction even in the eventuality of transient movement between the spigot portions during injection. Preferably, the non-return valve of the present invention is also configured to include a means for mutually aligning and/or guiding the complementary valve components that ensures a proper alignment between the complementary spigot portions, and may also serve to improve the function and longevity of a face-seal, when present. The non-return valve of the present invention provides particularly advantageous utility when configured for use in a barrel assembly of an injection unit for the injection molding of a metal alloy.

摘要： Method and apparatus for a molding melt conduit and/or runner system includes coupling structure having a first surface configured to couple with a first melt conduit or manifold, and a second surface configured to couple with a second melt conduit or manifold. Cooling structure is configured to provide a coolant to the coupling structure. Preferably, the cooling structure cools the coupling structure to a temperature that causes any melt leaking from near the coupling structure to at least partially solidify thereby further sealing the connection(s).
