Abstract

An injection molding machine screw extrusion rod structure is characterized by comprising a tube body and a hard fixed structure on the outer surface of the tube body, and the hard fixed structure is in overall or separate fixed connection with the tube body. The advantages are that when the outer layer is coated with a heat insulation material, a limiting structure fixes the heat insulation material external protective layer to effectively ensure that the soft heat insulation material and the tube body are not peeled and not squeezed and deformed. The injection molding machine screw extrusion rod structure has the advantages of simple structure, low design and manufacturing cost and wide market prospect. In a certain distance, annular or spiral artifacts and other accretion or additional links can be processed to enhance the pipeline friction to thrust and fix the pipeline.

Description

technical field [0001] The invention relates to the field of pipe structures, and in particular provides a screw extrusion rod structure for an injection molding machine. Background technique [0002] Non-metallic pipes and composite pipes have a large coefficient of linear expansion. Under the action of pressure and temperature, the pipeline expands and contracts, and the axial deformation is difficult to control. The technology of adding traditional fixed piers and thrust piers is not mature enough, and the cost is high and the operation is cumbersome; therefore, There is an urgent need for a non-metallic pipe that can meet the fixed requirements on the market. Contents of the invention [0003] [0004] The object of the present invention is to provide a screw extrusion rod structure for an injection molding machine. [0005] The invention provides a screw extruded rod structure of an injection molding machine, which is characterized in that: the screw extruded rod st...
