Abstract

The invention discloses a filtering and mixing nozzle, and belongs to the field of injection molding machines. The filtering and mixing nozzle comprises a sub-nozzle, a flange connector, a rheologicalvalve element head and at least one prismatic rheological valve element. The rheological valve element head and the prismatic rheological valve elements are mounted in the filtering and mixing nozzle. Through dual rheology of the prismatic rheological valve elements and the rheological valve element head, molten plastic can be subjected to guiding, cross combining and compression guiding; througha first V-shaped variable flow portion of the rheological valve element head, and plastic flowing out from the prismatic rheological valve elements can be gathered to the rheological valve element head and then is compressed and guided to the sub-nozzle to be output; and guiding is constantly achieved in the sub-nozzle and a through hole of the flange connector, the phenomena that plastic is notcompletely combined in a screw pipe and colors are not uniform can be remedied, foreign matter in the plastic can be filtered in the prismatic rheological valve elements or the rheological valve element head during guiding, and the functions of achieving uniform plastifying and filtering foreign matter in raw materials can be achieved.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to filtering and mixing nozzles. Background technique [0002] As the types of plastics in the injection molding industry continue to be updated, their performance continues to improve, and plastic additives are also constantly changing and increasing, making it increasingly difficult to improve product quality by completely relying on injection molding processes or screw design. One of the most difficult problems to solve is the uneven color mixing and poor plasticization of the product. Moreover, the overall price of plastic raw materials continues to rise, and the proportion of recycled materials used by many companies continues to increase. However, it is inevitable that foreign objects, such as iron filings, will enter the hot runner of the mold during the production process and cause blockage during the use of recycled materials. Cause unnecessary losses and a lot of...
