Embodiment Construction

[0028] In the following, the present invention will be described in detail and specifically through specific examples, so as to better understand the present invention, but the following examples do not limit the scope of the present invention.

[0029] In some embodiments, such as figure 1 As shown, there is provided a melting and kneading nozzle installed at the front end of the material tube of the injection molding machine to improve and compensate for the insufficient mixing of the screw or the poor mixing effect. The flange connecting body 20 and at least one melting-increasing valve core 30, the melting-increasing valve core 30 is arranged in the assembly cavity formed by the flange connecting body 20 and the sub-injection nozzle 10, and the melting-increasing valve core 30 There can be multiple, multiple melting spools 30 sequentially abutted and connected, the overall installation and disassembly is convenient and fast, and the cleaning is very easy.

Abstract

The invention discloses a melting-increasing mixing nozzle. The melting-increasing mixing nozzle comprises a sub-nozzle, a flange connector and at least one melting-increasing valve core, the melting-increasing valve core is of a cylinder structure, at least one group of mixing flow channels are formed in the periphery of the melting-increasing valve core in the axial direction, and each mixing flow channel is formed by connecting a plurality of grooves with different depths. The melting-increasing valve core in the melting-increasing mixing nozzle adopts the cylindrical structure, and the plurality of grooves with different depths are formed in the periphery of the melting-increasing valve core, so that plastic is better to climb over, melt and mix, and the injection molding quality is greatly improved; and the nozzle is simple and novel in structural design, the defects that an existing screw is poor in plasticization and color mixing, unstable in glue melting time, not easy to clean after color changing, black spots and black lines exist and the like are effectively overcome, the production efficiency is improved, and the production cost of enterprises is reduced.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and relates to a mixing nozzle, in particular to a melting and mixing nozzle. Background technique [0002] Nowadays, the types of plastics in the injection molding industry are constantly updated, and their performance is continuously improved. The market competition is very fierce, and the profits of processing companies are getting lower and lower, and the injection molding industry is even more fierce. We all know the three most critical factors in the injection molding industry: raw materials, machines, and molds. Raw materials are the most critical factors in the injection molding industry. At present, the types of raw materials are increasing continuously, and there are more and more modified plastics. The additives, toners, and color masterbatches in them are also becoming more and more complicated. The original standard screw design problems are gradually revealed. There are m...
