The invention provides an injection nozzle and an injection molding machine comprising the same. An injection molding channel allowing molten rubber to flow through is formed inside the injection nozzle; a filtering device is arranged in the injection molding channel and is sequentially divided into a rubber inlet end, a filtering end and a rubber outlet end in the flowing direction of the rubber;the periphery of the rubber inlet end and the periphery of the rubber outlet end are matched with the inner surface of the injection molding channel; at least one rubber inlet groove and at least onerubber outlet groove are formed in the outer side wall of the filtering end and are arranged at intervals; gaps exist among groove edges between the rubber inlet grooves and the rubber outlet groovesand the inner surface of the injection molding channel; a plurality of rubber inlet channels allowing the rubber to flow into the rubber inlet grooves are formed in the rubber inlet end; and a plurality of rubber outlet channels allowing the rubber to flow out of the rubber outlet grooves are formed in the rubber outlet end. Thus, impurities in the molten rubber can be filtered.
Description
Technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to an injection nozzle and an injection molding machine having the injection nozzle. Background technique [0002] The injection molding machine is a plastic injection molding machine. When it is working, it will melt the solid plastic particles to obtain a molten colloid, and inject the molten colloid into the hot runner system through the barrel and injection nozzle. In practice, recycled materials and some stabilizers, fillers and other additives are usually added to the plastic particle raw materials. Due to the different melting points of the plastic raw materials and additives, the molten colloid in the material tube is under different working conditions. It appears that the molten colloid does not fully melt, with large particles of solid matter, that is, the molten colloid contains impurities. It is understandable that this will cause blockage of the hot runn...
