Abstract

The invention provides a screw and an injection molding machine. The screw comprises a connecting shaft, a homogenizing section, a compressing section and a feeding section. The homogenizing section,the compressing section and the feeding section are sequentially arranged on the connecting shaft in a sleeving manner. The homogenizing section and the feeding section are of equal-diameter structures, the diameter of the homogenizing section is larger than that of the feeding section, the diameter of the compressing section is gradually reduced from the homogenizing section to the feeding section, the diameter of the first end, close to the homogenizing section, of the compressing section and the diameter of the homogenizing section are equal, and the diameter of the second end, close to thehomogenizing section, of the compressing section and the diameter of the feeding section are equal. According to the technical scheme, the problem that when a screw of an injection molding machine inthe prior art is replaced, it is needed to replace the whole screw is solved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a screw and an injection molding machine. Background technique [0002] The screw is one of the key components of the injection molding machine. When the injection molding machine is working, the granular or powdery plastic is first added into the barrel, and the granular or powdery plastic is plasticized by rotating the screw relative to the barrel and heating the outer wall of the barrel. Become the plastic in the molten state, and then use the screw to inject the plasticized plastic in the molten state into the cavity of the molding mold at a higher pressure and faster speed. The structure of the screw will affect the effect of the plastic. For different types of plastics, different screw structures are required, and the screw is easy to wear during use. [0003] However, the screw in the related art adopts an integrated design. When it is necessary to chan...
