Plasticizing injection molding mechanism of injection molding machine and use method for plasticizing injection molding mechanism

Abstract

The invention discloses a plasticizing injection molding mechanism of an injection molding machine. The plasticizing injection molding mechanism comprises an injection molding material barrel, a material feeding hopper and a conveying pipe, wherein one side of the injection molding material barrel is provided with the conveying pipe in an integrated forming mode, and one side of the conveying pipe is provided with a regulation and control mechanism in a connected mode. According to the plasticizing injection molding mechanism of the injection molding machine designed by the invention, by means of coordination effect of the arrangements of the material feeding hopper, the conveying pipe, a quantitative mechanism, the regulation and control mechanism and a positioning structure, on the one hand, added materials can be added in equal quantities, so that the phenomenon of blocking by adding too much at a time is avoided, and normal proceeding of material conveying is guaranteed. By means of the use method for the plasticizing injection molding mechanism of the injection molding machine, the material feeding speed of the materials can be correspondingly adjusted, the material feeding flexibility of the plasticizing injection molding mechanism is improved, the actual production requirements can be better met, and then the economic benefits of production and processing are improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a plasticizing and injection molding mechanism of an injection molding machine and a method for using the same. Background technique [0002] The plasticizing injection molding mechanism is an important equipment of the injection molding machine. The plasticizing and heating process of the plastic is completed in the injection molding mechanism; most of the current plasticizing injection molding mechanisms rely on the heat supply of the external heater and the screw rotation through the plasticization of the screw type. The joint action of the shear friction heat caused by the inside of the plastic has better plasticity; but in the prior art, because the rotation speed of the heating screw is affected by the viscosity of the plastic solution and the safety angle, the rotation speed of the heating screw is relatively low , The plasticized plastic cannot be fully...

[0002] The plasticizing injection molding mechanism is an important equipment of the injection molding machine. The plasticizing and heating process of the plastic is completed in the injection molding mechanism; most of the current plasticizing injection molding mechanisms rely on the heat supply of the external heater and the screw rotation through the plasticization of the screw type. The joint action of the shear friction heat caused by the inside of the plastic has better plasticity; but in the prior art, because the rotation speed of the heating screw is affected by the viscosity of the plastic solution and the safety angle, the rotation speed of the heating screw is relatively low , the plasticized plastic cannot be fully stirred, and the uniformity of plasticization is poor

[0003] At present, the Chinese patent document with the authorized notification number CN107901365A discloses a plasticizing injection molding mechanism of an injection molding machine. When the filler is working, if there is too much filler at one time, it may cause material blockage and uneven feeding, and it cannot be controlled according to the actual production demand, which will affect the production and processing efficiency.
