Technical Field
[0001] The utility model belongs to the technical field of injection molding machines, and more specifically relates to a screw barrel of an injection molding machine. Background Art
[0002] Injection molding machines are usually used to make thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding machines can heat plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity. The screw and barrel of the injection molding machine are key components in the plastic injection molding process. They work together to achieve the melting, mixing and injection of plastics.
[0003] When using the current screw barrel of an injection molding machine, the staff often finds that during the operation of the injection molding machine, the equipment will be briefly shut down due to production needs to replace or clean the mold. During the shutdown process, there is still molten plastic stored in the barrel of the injection molding machine. The cooling of the molten plastic will cause the plastic to block the inside of the barrel. The current screw barrel of an injection molding machine is usually a completed cylinder, which is difficult to clean and dredge after being blocked. Utility Model Content

When the rotating shaft rotates, the two circular rods can be driven to rotate to stir the material, and when the stirring block rotates, it will vibrate through the action of the second spring to improve the stirring effect, thereby further preventing the material from being blocked.
[0014] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:
[0015] In the utility model, by setting the mounting structure, the first half cylinder and the second half cylinder are connected together to form a complete material cylinder.

The output shaft of the motor 61 drives the rotating shaft 62 to rotate, and then drives the auger 63 to rotate, which can guide the material to prevent the material from being blocked. When the rotating shaft 62 rotates, it can drive the two round rods 64 to rotate to stir the material, and when the stirring block 68 rotates, it will vibrate through the action of the second spring 67 to improve the stirring effect, thereby further preventing the material from being blocked.
