Problems solved by technology

[0004] For the existing single-screw melt glue injection device, since the material is fed in the form of a single screw, it is prone to material accumulation, resulting in insufficient mixing and kneading of the material, resulting in poor product quality, energy consumption, and high production costs.

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as Figures 1 to 12 As shown, the melt injection device for injection molding machine in this implementation includes plasticizing components, a power distribution mechanism 4, a hydraulic motor 5, and the like.

[0032] Among them, the plasticizing part includes a barrel 1 and a screw arranged in the barrel 1. There are three screws arranged in the barrel 1, and the three screws are arranged in a triangle. As another form of the arrangement of the three screws, it can also be three screws. They are arranged in parallel, and meanwhile, the inner wall of the barrel 1 is tangent to the outer trajectory formed by the rotation of the three screws.

[0033] There are three ways of contacting the above three screws. In the first way, each screw meshes with each other, which can improve the extrusion effect on the material; in the second...

Abstract

The invention discloses a glue injection device for an injection molding machine. The glue injection device comprises a plastifying part, wherein the plastifying part comprises a material barrel and screw rods arranged in the material barrel; the glue injection device for the injection molding machine is characterized in that three screw rods are arranged in the material barrel and are arranged triangularly or in a linearly parallel manner, and the inner wall of the material barrel is tangent with the outer trajectory formed by rotation of three screw rods. According to the glue injection device for the injection molding machine, three screw rods are adopted to forcibly convey the material, screw ridges and screw grooves of each screw rod have speed difference, so that the material can be fully extruded, ground and mixed and has good self-cleaning property and good calendaring effect, the quality of products is improved, and the single energy consumption and the processing cost are reduced.

Description

technical field [0001] The invention relates to an injection device, in particular to a melt glue injection device for an injection molding machine. Background technique [0002] At present, injection molding machines generally use single-screw melt injection. The screw-type plasticizing components used in existing injection molding machines are mainly composed of screws, barrels, nozzles, etc., which are the core components to complete uniform plasticization and quantitative injection. [0003] The specific working principle of the screw-type plasticizing part is: when pre-plasticizing, the screw rotates to continuously push the material falling into the screw groove from the material opening forward, and the heating ring transfers heat to the material through the wall of the material cylinder, and the solid material is outside Under the dual effects of heating and screw rotation and shearing, and through the thermal history of each functional section of the screw, plastici...
