Hot-channel distribution block for an injection molding system which conducts the melt from the injection molding machine through flow channels to injection nozzles connected to the molding tools. Melt chambers are positioned adjacent the flow channels to the injection nozzles. Movable thrust pistons are placed in the melt chambers and, when actuated, force the melt present in the melt chambers at the required pressure into the tool cavities and into the flow-channel sections leading to it. The melt chambers can be positioned adjacent the connection or junction of flow channels.
