Abstract

The invention discloses a high-precision novel screw. The high-precision novel screw comprises a screw head, a first screw edge, a first screw body, a second screw body, multiple convex columns, a third screw body, stirring rods, a second screw edge and a fourth screw body; the first screw body is arranged under the screw head, the second screw body is arranged under the first screw body, the third screw body is arranged under the second screw body, and the fourth screw body is arranged under the third screw body; the first screw edge extending from top to bottom is arranged on the outer sideof the first screw body; the multiple convex columns are arranged on the outer side of the second screw body; the third screw body and the second screw body achieve transition through a slope; the third screw body and the fourth screw body achieve transition through a slope; the left side and the right side of the third screw body are provided with the stirring rods correspondingly; and the secondscrew edge extending from top to bottom is arranged on the outer side of the fourth screw body. The high-precision novel screw has the advantage that the screw edge structure is complex.

Description

technical field [0001] The invention relates to a high-precision novel screw rod, which belongs to the technical field of screw rods. Background technique [0002] The screw is an important component of the plasticizing device. It is combined with a barrel, a heating device, an injection mechanism, and a rotary drive mechanism to form a complete injection molding unit. The main function of the screw is to transport, melt and mix the plastic. The mixing ability of the screw in the prior art is limited and affected by the structure of the screw flight, so it is relatively weak. In order to solve the above difficulties, it is necessary to develop a high-precision new screw with complex flight structure. Contents of the invention [0003] The purpose of the present invention is to provide high-precision novel screw. [0004] The problem to be solved by the present invention is that the mixing ability of the screw in the prior art is limited and affected by the structure of t...
