The present invention is a hot runner nozzle design consisting of a nozzle core with slotted flange seated inside a slotted nozzle housing, a nozzle tip seated on the nozzle core, and a nozzle tip seal seated on the nozzle tip. Furthermore, the present invention is a quick assembly hot runner nozzle design. The present nozzle design provides for the easy installation and removal of the nozzle by means of turning and sliding the nozzle. This provides for easy installation or removal of the nozzle when servicing the mold in the machine and without the complete disassembly of the hot runner mold. The seal located on the nozzle tip seals the tip area to avoid plastic leakage. Positioning the seal closer to the gate area also contributes in increased nozzle tip mass thus resulting in a better heat distribution profile along the nozzle tip, and especially in the area closer to the gate. This eliminates nozzle tip freeze up, a critical matter for inside center gate applications that may have extended nozzle tips or tight pitch applications. Furthermore, the seal seated on the nozzle tip allows for a better concentric alignment of the nozzle to gate. Also, positioning the seal close to the gate area decreases color change time because of less volume being trapped around the nozzle tip.
