<p>An injection molding machine is provided that includes a manifold (30) for distributing plastic melt flow to one or more mold cavities (120). The manifold (30) has a flow channel having an output orifice surrounded by a lower outside surface (140), and is expandable upon heating. The injection molding machine also includes a nozzle (10) comprising a body mounted in a receiving aperture (180,190) in a stationary housing (20,110) aligned with a gate (100) to a mold cavity (120), the body having a central bore (18) for delivering plastic melt flow from the channel in the manifold to the mold cavity, the body having an upper surface (130) for engaging with the lower surface (140) of the manifold (30). The body has a lip member comprising an outer leg (250) circumferentially spaced from an inner body section (270) of the body, the outer leg (250) having a surface (240) mounted against a mounting surface (260) of a stationary housing (20). The manifold (30) is mounted adjacent to the stationary housing (20) and the nozzle is mounted in or on the stationary housing such that the upper surface (130) of the body of the nozzle faces the lower surface (140) of the manifold (30) for engagement therewith. The lower surface (140) of the manifold engages the upper surface (130) of the body of the nozzle under compression, the outer leg (250) of the lip member being compressed by the compression between the engaged upper surface (130) of the body and the lower surface (140) of the manifold. <IMAGE></p> |
