Abstract
A cold runner block (38) has spaced drop holes (54) arranged in a selected pattern for supplying fluid molding material to nozzles (60) connected to the mold gates (62). The drop holes (54) open on nozzle runners (52) in the cold runner block (38) which are in communication with a source of fluid molding material. Close-off rods (68) are selectively positioned in the runners (52) to block the flow of fluid molding material beyond the drop holes (54) communicating with a mold (12) for an object of a particular size and shape. Drop hole plugs (66) are provided for the drop holes (54) which open on the nozzle runners (52) in the section of the runners (52) not blocked by the close-off rods (68).
