Abstract
An injection molding integral cooled socket holder to be seated in a well in a cavity plate to receive an elongated heated nozzle. A central tube portion extends between a rear collar portion and a forward socket portion to form an elongated socket to receive the nozzle. The tube portion has small diameter inlet and outlet tubes received in longitudinal grooves which carry a flow of cooling water which is received at the rear collar portion to the forward socket portion. The water flows around a circular conduit in the forward socket portion to provide cooling adjacent the gate. The components of the socket holder are integrally brazed together in a vacuum furnace. Socket holders are made with various preselected lengths to match different length nozzles by cutting the central tube portion including the inlet and outlet tubes to different standard lengths.
