[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are widely used in the plastics processing industry. During the operation of an injection molding machine, material is typically stored in a hopper, which is metered in by opening a valve in the hopper. After material is added, the machine melts and plasticizes it, applies pressure to inject it, fills the mold, and cools it. Finally, the mold is opened to remove the part, and after removing the part, the mold is closed again to begin the next cycle.

[0003] However, in existing injection molding machines, materials are easily stuck at the discharge port during discharge, resulting in unsmooth discharge and requiring manual turning to clear the discharge port.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content

[0031] The docking assembly 6 is arranged at the bottom of the silo 1;

[0032] Dispersing component 5, which is arranged on the top of the silo 1;

[0033] The driving motor 3 and the stirring assembly are installed on the top of the silo 1, and the stirring assembly is arranged inside the silo 1;

[0034] The stirring assembly includes a central shaft 4-1, which is rotatably connected to the top of the silo 1, and the upper end of the central shaft 4-1 is connected to the output end of the drive motor 3. A pair of cross bars 4-2 are provided on the opposite end surfaces of the central shaft 4-1, and a movable frame 4-3 is slidably connected on the pair of cross bars 4-2. A limiting plate 4-4 is fixedly connected to the cross bars 4-2, and a pair of springs 4-5 are sleeved on the cross bars 4-2. The springs 4-5 are respectively located at both ends of the movable frame 4-3. A circular plate 4-6 is provided at the lower end of the central shaft 4-1, and the circular plate 4-6 is rotatably connected to the bottom of the silo 1. A dispersion discharge hole 4-7 is opened on the surface of the circular plate 4-6, and a number of stirring rods 4-8 are provided on the central shaft 4-1.

[0035] In this embodiment, in order to achieve the effect of keeping the material active and not piling up when unloading, a stirring assembly is designed. A central shaft 4-1 is rotatably connected to the top of the silo 1 and is controlled to rotate by a drive motor 3. Two cross bars 4-2 are provided at both ends of the surface of the central shaft 4-1. A movable frame 4-3 is slidably connected to the cross bar 4-2. When the central shaft 4-1 rotates, the movable frame 4-3 can move on the surface of the cross bar 4-2, and two springs 4-5 are fitted on the cross bar 4-2. The elastic force can prevent the movable frame 4-3 from being fixed, and the material can be continuously stirred. A circular plate 4-6 is provided at the lower end of the central shaft 4-1 and a dispersion discharge hole 4-7 is opened. The circular plate 4-6 keeps rotating and continuously discharges material through the dispersion discharge hole 4-7. A stirring rod 4-8 is also provided to stir the material at the bottom as it rotates.

[0036] Furthermore, the dispersion component 5 includes a second motor 5-1, which is installed on the top of the silo 1. A dispersion rack 5-2 is provided at the output end of the second motor 5-1. An inner cover 5-3 is provided on the top of the silo 1, and the inner cover 5-3 is connected to the feeding pipe 2.

[0037] In this embodiment, in order to achieve the effect of breaking up the input material, a dispersion component 5 is designed. An inner cover 5-3 for feeding is provided at the top of the silo 1, and a second motor 5-1 and a dispersion rack 5-2 are installed on the top. The dispersion rack 5-2 is located below the opening of the inner cover 5-3. When the material is input, the dispersion rack 5-2 can be kept rotating at a high speed, so that the agglomerated material can be broken up when it is input.

[0038] Furthermore, the docking assembly 6 includes a plurality of sleeves 6-1, which are fixed around the bottom of the outer surface of the silo 1. A docking cover 6-2 is connected to the bottom of the feeding pipe 2. A plurality of connecting holes 6-3 are provided on the surface of the docking cover 6-2. A plurality of docking rods 6-4 are provided around the side surface of the docking cover 6-2. The docking rods 6-4 are inserted into the sleeve 6-1.

[0039] In this embodiment, in order to achieve the effect of connecting with the injection molding equipment, a docking component 6 is designed.

[0042] Furthermore, a plurality of fixing rods 7 are provided on the surface of the bottom of the silo 1 , and the fixing rods 7 are in an L-shaped structure.

[0043] In this embodiment, by installing a plurality of fixing rods 7, the material on the surface can be pushed by the fixing rods 7 when the circular plates 4-6 rotate, thereby preventing the material from being stuck.

[0044] Furthermore, the stirring rods 4-8 are distributed in a cross-shaped structure.

[0045] In this embodiment, the stirring rods 4-8 are kept rotating above the discharge point through the cross-shaped azimuth distribution, so that the material continues to flow.

[0046] When it is needed, the docking cover 6-2 is connected to the injection molding equipment through the connecting hole 6-3, the silo 1 is put on the docking rod 6-4 through the sleeve 6-1 and inserted downward, the material is poured into the feeding pipe 2, and the second motor 5-1 is started to break up the incoming material through the dispersion rack 5-2. When feeding the injection molding machine, the drive motor 3 is started to control the rotation of the central shaft 4-1, so that the cross bar 4-2, the movable rack 4-3 and the stirring rod 4-8 continue to rotate and stir the material. At the same time, the circular plate 4-6 also keeps rotating synchronously, and the material is discharged outward through the dispersion discharge hole 4-7.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
