Abstract
According to the present invention a coding plate is interspersed between first and second respective inlet and outlet cross over nozzle parts. The cooling plate engages ends of the cross over nozzles during mould filling and provides a melt transfer passage therebetween. Once the mould is filled, the cooling plate acts to dissipate heat from the melt transfer passage thereby promoting solidification of melt therein. Accordingly melt solidification in the sprue is assured with more certainty than prior art designs enabling relatively fax mould cycling with minimal risk of drool.
