High molecule polymer diversion and rotation device

Abstract

The invention relates to a device for reducing the conveying resistance of high molecular polymer and uniform internal temperature of high molecular polymer during the conveying process, which includes a flange, a nozzle and a main part, and a first conical fitting surface is arranged between the nozzle and the main part and a number of spiral flow passages guided by the first conical fitting surface, the two ends of the spiral flow passage correspond to the flange and the nozzle flow passage, the main part and the flange are provided with a second conical fitting surface, On the second conical mating surface, there is a distribution groove communicating with the through hole and the flange flow channel arranged on the main body part. The beneficial effect of the present invention is that the device is installed on the injection head of the injection molding machine, and the high molecular polymers are diverted during the conveying process, and then converged, and generate spiral rotation, which can homogenize the internal temperature and disperse pigments or additives more effectively; at the same time Because the material rotates while being squeezed into the mold cavity, the molecular chain orientation inside the polymer is helical, and the molecular chain orientation of the material injected into the mold cavity is helical, which improves the physical properties of the product. Anisotropy.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a device for reducing the conveying resistance of high-molecular polymers and the internal temperature of uniform high-molecular polymers 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. Such as figure 1 The injection structure of an ordinary injection molding machine is shown, and 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. Through the flow channel 20 in the flange 2 and the flow channel 10 in the nozzle 1, it is injected into the mold cavity. When the material is ejected from...
