Abstract

The invention discloses an injection device for an injection molding machine. The injection device comprises a main barrel; a charging hopper is arranged at the upper end of the main barrel; an oblique filter screen is arranged in the charging hopper; the upper end of the filter screen is fixedly connected with the inner wall of the charging hopper; the lower end of the filter screen penetrates through an opening in the side wall of the charging hopper and extends to the outer side of the charging hopper; the upper end of the main barrel is fixedly connected with a box body; a strip-type opening corresponding the filter screen in position is formed in the side wall of the box body; a breaking mechanism is arranged in the box body; the breaking mechanism is connected with a driving motor through a transmission mechanism; an axial through hole is formed in the main barrel; the interior of the main barrel is connected with a threaded rod by threads; one end of the threaded rod is connected with a nozzle; the other end of the threaded rod is connected with a driving shaft of a driving motor; and the driving shaft penetrates through the rear side wall of the main barrel and is fixedly connected with the threaded rod. The charging hopper can be effectively prevented from being blocked, rapid injection molding on a mould is realized, and the injection device is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to an injection device for an injection molding machine. Background technique [0002] Injection molding machine is mainly used to process thermoplastics or thermosetting plastics into crude plastic products. Injection device is essential in the injection molding process. It is mainly composed of screw, barrel, screw head, injection nozzle, heating resistor, Driven by the motor, the screw is driven by the motor, the plastic falls from the barrel, and is conveyed forward through the screw. Under the shearing and mixing action of the heating cylinder and the screw, the plastic is gradually melted, and the plastic is melted at the set injection pressure. Inject the molten material from the injection nozzle into the mold cavity at a certain speed. The barrel of the existing injection device is used to directly heat the plastic particles, and the discharge port of th...
