摘要： A support for rotating molds used in multi-shot injection molding provides for platen mounting of a support track that may extend beneath the molds to support the rotating mold portion. The extensible track provides a telescoping configuration that allows a long support span independent of the mold width improving mold stability and increasing potential mold separation for easy access to the mold portions.

摘要： A multi-shot, injection molded valve has at least two independent elements which are rotatably and non-detachably connected together. The valve includes a stationary housing and a pitcock rotatably mounted therein. The stationary housing is molded in a first shot with at least one inlet projecting from one side of the housing and at least one outlet projecting from another side of the housing. The housing has a substantially cylindrical upper portion defining a first bearing surface, and a substantially cylindrical lower portion defining a second bearing surface, the upper and lower portions being divided by a substantially cylindrical rib. The pitcock is molded in a second shot with an external grip portion, an upper cylindrical segment beneath the grip portion and a lower cylindrical segment separated from the upper cylindrical segment by a substantially cylindrical undercut which is engageable with the rib on the housing. The pitcock is also provided with a second passageway which is selectively aligned with the first passageway of the housing upon rotation of the pitcock in the housing.

摘要翻译： 多注射成型阀具有至少两个独立的元件，其可旋转和不可拆卸地连接在一起。 阀包括固定壳体和可旋转地安装在其中的凹坑。 固定壳体以第一次射入模制，其中至少一个入口从壳体的一侧突出并且至少一个出口从壳体的另一侧突出。 壳体具有限定第一支承表面的基本上圆柱形的上部部分和限定第二支承表面的基本上圆柱形的下部，上部和下部由基本上圆柱形的肋分隔开。 球窝在第二次射击中被模制成具有外部握持部分，在握持部分下方的上部圆柱形部分和通过基本上圆柱形的底切部分与下部圆柱形部分分离的下部圆柱形部分，其可与壳体上的肋接合。 孔雀还设置有第二通道，当第一通道在壳体中旋转时，该第二通道选择性地与壳体的第一通道对准。
