Abstract

The invention discloses a comb type mixing nozzle of an injection molding machine. The comb type mixing nozzle comprises a nozzle head and a nozzle body which are mutually connected. A comb type mixing component is arranged in the nozzle body, the comb type mixing component is in a cylindrical object, the surface of the comb type mixing component is provided with one or more feeding channels and one or more discharge channels, one end of each feeding channel is closed, the other end of each feeding channel is opened and penetrates to the feeding end of the comb type mixing component, the opened ends of the feeding channels communicate with an inner cavity of the nozzle body, one end of each discharge channel is closed, the other end of each discharge channel is opened and penetrates to thedischarge end of the comb type mixing component, the opened ends of the discharge channels communicate with an inner cavity of the nozzle head, a glue passing comb structure is arranged between the feeding channels and the discharge channels, and the feeding channels communicate with the discharge channels through the glue passing comb structure. The plasticizing and mixing effect of plastic meltis effectively improved, plastic materials are more uniform, and therefore the appearance quality and mechanical property of plastic products can be improved.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a comb-type mixing nozzle of the injection molding machine. Background technique [0002] Due to the rapid development of the plastics industry, the application fields of plastic products continue to expand, and it often occurs that the mixing effect of the traditional mixing nozzle cannot meet the requirements of certain products. In order to solve this situation, it is necessary to design a mixing effect with better mixing effect. Mouth. In order to solve the above problems, Chinese Patent Document No. CN201998382U disclosed a filter-type static mixing nozzle on October 5, 2011, specifically disclosing that it includes a mixing jacket with a channel inside, and is sealed and fixedly connected at one end of the mixing jacket. A joint, the other end of the mixing coat is sealed and fixedly connected to a nozzle, and several shearing and dispersing mixing nets are arranged in the m...
