Screw barrel component for injection molding machine

Abstract

The invention discloses a screw barrel component for an injection molding machine. The screw barrel component comprises a barrel, and the inner wall of the barrel is fixedly connected with a barrel bushing; and the inner right side of the barrel is fixedly connected with a driving device, and the barrel bushing is internally provided with an outer screw rod. The invention relates to the technicalfield of injection molding machines. According to the screw barrel component for the injection molding machine, through arrangement an inner screw rod in the outer screw rod, the inner screw rod absorbs heat for providing heat energy to the outer screw rod and improving the rotating force of the outer screw rod, so that tremendous internal friction heat generated by interface shear, of polymers atthe clearance position between the barrel bushing and the outer screw rod is increased; quick and efficient fusion of the polymers is achieved, and then one side of a feed chute communicates with oneside of a fine groove through rotation of a cylindrical rod in a cylindrical pipe; since a material separation mechanism is arranged, the waiting time of the injection molding machine can be shortened effectively; and the working efficiency of the injection molding machine can be improved greatly, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a screw and barrel assembly of an injection molding machine. Background technique [0002] Plastic machines are also known as injection molding machines or injection molding machines. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding dies. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applying high pressure to the molten plastic so that it is ejected to fill the mold cavity. The working principle of the injection molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous state) into the closed mold cavity. The process of obtaining products after curing and shaping. Injection molding is a ...
