A hot runner nozzle includes a nozzle body configured to define a flow path of molten resin, and a cover member arranged at a circumference of a tip portion of the nozzle body. The cover member includes a first engagement portion being arranged on a part of an outer periphery and configured to engage with a mold and/or a second engagement portion being arranged on a part of an inner periphery and configured to engage with the nozzle body.

A valve-gating injection molding apparatus is disclosed. The valve gating injection molding apparatus has a manifold with a manifold channel extending therethrough and a nozzle coupled to the manifold and having a nozzle channel in fluid communication with the manifold channel A valve pin extends across the manifold and through the nozzle channel. An actuator coupled to the valve pin for translating the valve pin between open and closed positions. A plurality of mold plates forming an enclosure to house the manifold, the plurality of mold plates defining an egress passageway through which the valve pin extends and a diversion chute that intersects the egress passageway at an angle.

An injection moulding tool for producing at least one injection-moulded part with an outer shape and an inner shape includes at least one cavity and, for every cavity, one hot-runner nozzle connected thereto, which has an annular nozzle mouth for injecting at least one melt into the cavity. The at least one cavity is formed by a cooled die, which forms the outer form for the outer shape of the injection-moulded part to be produced, and by a core, which forms the inner form for the inner shape of the injection-moulded part to be produced. The hot-runner nozzle has a nozzle core and a hollow needle, which can be moved along the nozzle core for opening and closing the annular nozzle mouth. The nozzle core protrudes beyond the annular nozzle mouth of the hot-runner nozzle and the nozzle core forms the core of the cavity of the injection mould.

The drive train configured for moving the at least one closure element arranged in the nozzle head in a first direction. The drive train comprising a cam mechanism that comprises a cam head. The cam head comprising a cam head block. Per closure element, the cam head block comprising a bracket. The bracket comprising at least one inlay. Per closure element, the at least one inlay comprising a first drive surface configured for engaging and driving a second drive surface arranged at the closure element at least during closing of the closure element. Per closure element, the cam head block comprising a third drive surface configured f engaging and driving a fourth drive surface arranged at the closure element at least during opening of the closure element.

The invention is directed to an injection nozzle (1) for an injection molding device comprising. At least one closure element (4) is arranged movable in a nozzle head (2) in a first direction (a). A cam mechanism (5) comprises a cam head (6) with a cam head block (7). Per closure element (4) the cam head block (7) comprises a bracket (8). The bracket (8) comprises at least one inlay (9). Per closure element (4) the at least one inlay (9) comprises a first drive surface (10) which interacts with a second drive surface (11) arranged at the closure element (4) at least during closing of the closure element (4). The cam head block (7) per closure element (4) comprises a third drive surface (12) which interacts with a fourth drive surface (13) arranged at the closure element (4) at least during opening of the closure element (4).
