High molecule polymer diversion and rotation device

Abstract

The invention relates to a device for reducing the transmission resistance of macromolecule polymer and making the internal temperature uniform, wherein the invention is characterized in that: it comprises flange, nozzle and main body; there is the first taper match surface and several screw channels between the nozzle and main body; two ends of screw channel are though to the nozzle. The invention can be mounted at the head of injection to divert, collect and rotate the macromolecule polymer, to make the temperature uniform and disperse paint or additive uniformly; and since the material is rotated in chamber, the molecule chain will be screwed, to improve the physical property.

Description

Technical field

[0001] The invention relates to the injection process of an injection molding machine, in particular to a device for reducing the conveying resistance of high molecular polymer and uniform internal temperature of high molecular polymer during the conveying process. Background technique

[0002] Injection process of conventional injection molding machine: Use the screw to plasticize the material, and directly extrude it into the mold cavity through the screw or plunger. As shown in Figure 1, the injection structure of an ordinary injection molding machine is shown. Its working principle is: the plastic is plasticized and stored in the barrel 3 at the front end of the screw through the screw part 4, and the external force is applied to the screw 4, and the screw 4 pushes the material stored in the barrel. Material, the material is injected into the mold cavity through the flow channel 20 in the flange 2 and the flow channel 10 in the nozzle 1. When the materia...
