ABSTRACT:
A method and apparatus for distributing melt through three level stack molds. According to the method a crossover manifold is provided between adjacent mold levels of the stack mold, the crossover manifold having a plenum generally coaxial with a mold axis. Melt is introduced into the plenum through an inlet passage and distributed from the plenum to respective nozzle arrays through a separate outlet conduit associated with each mold level. The apparatus includes a crossover manifold mounted between first and second mold levels and having a plenum generally coaxial with the mold axis. An inlet conduit fluidly communicates with the plenum and an injection head to provide a melt path from the injection head into the plenum. A separate outlet conduit is provided for each mold level. Each outlet conduit fluidly communicates at one end with the plenum and at an opposite end with the injection nozzles of a respective mold level to provide a melt path from the plenum to each of the injection nozzles of the respective mold level. Each outlet conduit defines a respective melt path of generally equal length and resistance to melt flow.
