摘要： In a manifold, the valve pin has a sealing surface proximate its bottom end, which surface is engageable with a gate sealing surface to inhibit melt flow into the mold cavity. A first guidance and alignment structure is connected to the valve pin, and a second structure to the mould block upstream from the gate. Both structures include first and second guide surfaces of a diameter decreasing gradually in a downstream direction and first and second cylindrical alignment surfaces. The first guide surface is positioned immediately downstream from the first alignment surface, the second guide surface immediately upstream from the second alignment surface. The second guide surface is positioned to complete alignment of the valve pin with the gate prior to contact between the valve pin and gate. Further, it is positioned to engage the first alignment surface to maintain the valve pin in alignment with the gate during its movement towards the gate.

摘要： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and a first gap seal surface. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The first gap seal surface is positioned on a structure that is connected at least indirectly to the nozzle body. The first gap seal surface is adapted to be separated by a gap with respect to a second gap seal surface on the mold component. The gap is sized to inhibit the flow of melt between the first gap seal surface and the second gap seal surface.
