摘要： A molding nozzle (10) controls the flow of material from a source of plastic melt to an outlet that communicates with a gate (30) to a mold cavity (12). The nozzle (10) contains a valve pin (38) that includes a guide section (40) and a valve end (42), and is movable toward and away from the gate (30) to open and close the gate (30) selectively. The valve pin (38) is guided for movement by guide surfaces (64) on inwardly-extending vanes (62) within the nozzle (10), such that the guide surfaces (64) engage the guide section (40) of the valve pin (38). The valve end (42) of the valve pin (38) has a smaller diameter than that of the guide section (40), so that the valve section (42) is free-floating to allow annular flow in the guide surface region to minimize the likelihood of formation of flow lines in the molded part.

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： The invention relates to an injection molding machine having a plurality of modular drive groups which are arranged on the injection molding side and on the mold closure side. According to the invention, at least one of the drive groups (300, 400, 500) is connected to the injection molding machine via at least one multifunction element which, as an interface, makes it possible to optionally connect different types of drives, e.g. electromechanical drives, hydraulic drives, pneumatic drives, linear motors or electromagnetic drives as a drive group in an otherwise unmodified injection molding machine. Independent of the respective drive, space for the respectively used drive groups is provided on the injection molding machine in order to accommodate each type of drive. As a result, the structural requirements for an increased modularity are accomplished by using components which, to a great extent, are identical.
