    • 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 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 upstreams 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 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.
    • 在歧管中,阀销具有靠近其底端的密封表面,该表面可与门密封表面接合以阻止熔体流入空腔。 第一引导和对准结构连接到阀销,并且第二结构连接到模块上方的门。 两个结构都包括直径在下游方向逐渐减小的第一和第二引导表面以及第一和第二圆柱形对准表面。 第一引导表面位于紧邻第一对准表面的下游,第二引导表面紧邻第二对准表面的上游。 第二引导表面定位成在阀销和门之间接触之前完成阀销与闸门的对准。 此外,其定位成接合第一对准表面,以在其向门的移动期间使阀销保持与门对准。
