Abstract
An injection molding apparatus includes a manifold having a manifold channel for receiving a melt stream of moldable material from a source and delivering the melt stream to a nozzle channel of a nozzle. A mold cavity communicates with the nozzle channel to receive the melt stream through the mold gate. A distribution assembly is located adjacent to the manifold. The distribution assembly includes at least one distribution member including a first conduit and a second conduit extending therethrough for transporting a fluid from a source through the distribution assembly and for returning the fluid to the source. A valve box is sandwiched between the distribution member and the actuator. The valve box controls the flow of the fluid between the first and second conduits and the actuator.
