[0044] In this embodiment, the mixing barrel 11 is composed of two arc-shaped plate structures combined together to form a cylindrical structure, which can provide a relatively independent space for conveying injection molding raw materials; during the raw material conveying process, it is ensured that the raw materials can move in one direction along the inner wall of the mixing barrel 11.

[0045] Specifically, the rotating shaft 12 is coaxially arranged with the mixing barrel 11 ; the rotation of the rotating shaft 12 can drive the feeding blades 13 to rotate synchronously; the feeding blades 13 continuously transport the raw materials to one end of the discharge port of the mixing barrel 11 during the rotation process.

[0046] Furthermore, the feed blade 13 is arranged on the outside of the mixing barrel 11, and the feed blade 13 is a dragon blade structure formed by combining multiple groups of single blades; the interior of the rotating shaft 12 is a hollow structure, ensuring that the limit block connected to the inner wall of the feed blade 13 can be located inside the rotating shaft 12.

[0047] It should be noted that the feed blade 13 cooperates with the rotating shaft 12 so that the feed blade 13 can move along the axial direction of the rotating shaft 12; and when the rotating shaft 12 rotates, the feed blade 13 will also rotate synchronously with the rotating shaft 12 to achieve the purpose of spiral feeding; the reciprocating linear motion of the feed blade 13 can move the raw materials inside the mixing barrel 11 back and forth, so that the raw materials can be mixed more fully.

[0048] Furthermore, the transmission unit 2 includes a fixed frame 21, a first follower 22, a second follower 23 and a driving member 24; the first follower 22 is arranged on one side of the fixed frame 21, the first follower 22 and the second follower 23 are arranged opposite to each other, and the driving member 24 is arranged in the center of the fixed frame 21.

[0049] It should be noted that the second follower 23 is connected to the rotating shaft 12, and the rotation of the rotating shaft 12 can drive the feed blade 13 to rotate, so that the material can be transported by spiral feeding; and a protective cover is arranged on the outside of the transmission unit 2; the transmission unit 2 can be protected to a certain extent by the protective cover.

[0050] Specifically, the first follower 22 is connected to the linkage shaft 14, and the rotation of the first follower 22 drives the linkage shaft 14 to move; the movement of the linkage shaft 14 drives the feed blade 13 to move; during the movement, the feed blade 13 pulls the raw materials inside the mixing barrel 11 back and forth through the blade part arranged on the outside; the raw materials are mixed more fully in coordination with the spiral feeding process.

[0051] It should be noted that the active member 24 is installed inside the fixed frame 21 and is installed at a central position between the first driven member 22 and the second driven member 23. The active member 24 can rotate to simultaneously drive the first driven member 22 and the second driven member 23 to rotate; and then the active member 24 can rotate one circle to realize the spiral feeding of the feed blade 13 and the reciprocating movement of the feed blade 13 to mix the raw materials more fully.

[0052] The output end of the active member 24 is connected to a driving device, which can drive the active member 24 to rotate; the driving device is preferably a driving system composed of a motor driving a reduction gearbox; it can better drive the active member 24 to rotate stably.

[0053] In summary, the present invention pushes the raw materials inside the mixing barrel back and forth multiple times through the cooperation between the first follower and the feed blade, ensuring that the raw materials are mixed more fully; at the same time, the second follower cooperates with the rotating shaft to achieve intermittent feeding, thereby transporting the raw materials to the injection molding cavity.

[0059] It should be noted that the slide groove 122 is opened at the center of the rotating shaft 12, and the slide groove 122 passes through the side wall of the rotating shaft 12 and extends to its outside; during the installation process of the feed blade 13, a single set is arranged on the outside of the rotating shaft 12, and then multiple groups of feed blades 13 are connected; and the slider 131 is arranged on the inner wall of the feed blade 13, and the slider 131 slides along the inner wall of the slide groove 122; the feed blade 13 is slidingly connected to the rotating shaft 12, and the slider 131 slides along the inner wall of the slide groove 122.

[0060] Furthermore, the linkage shaft 14 includes a threaded sleeve 141 disposed at an end thereof; the threaded sleeve 141 is adapted to the screw rod 132 , and the threaded sleeve 141 and the screw rod 132 are threadedly connected.

[0061] It should be noted that the screw sleeve 141 is arranged at the end of the linkage shaft 14, and its end passes through the inside of the feed blade 13, and the screw sleeve 141 and the screw rod 132 are threadedly connected and fixed; and the other end of the linkage shaft 14 passes through the rotating shaft 12 and extends to its outside, and the linkage shaft 14 moves along the axial direction of the rotating shaft 12 to drive the feed blade 13 to move.

[0062] Furthermore, the first follower 22 includes a first U-shaped groove 221 opened on its arc surface; the second follower 23 includes a second U-shaped groove 231 opened on its arc surface; the active member 24 includes a support rod 242, and a lever 243 arranged at the end of the support rod 242; the lever 243 is respectively adapted to the first U-shaped groove 221 and the second U-shaped groove 231.

[0063] Specifically, the arc structure of the first follower 22 and the second follower 23 is the same, both of which are hemispherical structures; and the first follower 22 and the second follower 23 are symmetrically arranged on both sides of the fixed frame 21, and at the same time, the axis of the first follower 22 and the second follower 23 is the same; the angle between the support rod 242 and the plane of the active member 24 is an obtuse angle, and the lever 243 is perpendicular to the surface of the support rod 242; the angle between the support rod 242 and the plane of the active member 24 is preferably 135°.

[0064] Furthermore, the position of the lever 243 is adapted to the first U-shaped groove 221; during the rotation of the lever 243, its outer wall can squeeze the inner wall of the first U-shaped groove 221; thereby, the rotation of the active member 24 can drive the first driven member 22 to rotate; the movement principle of the second driven member 23 is the same as that of the first driven member 22, and no further elaboration is made here.

[0065] Furthermore, the active member 24 also includes an arc plate 241. The rotation of the active member 24 can drive the arc plate 241 to contact the end surface M of the second driven member 23 and the end surface N of the first driven member 22; one rotation of the active member 24 can drive the first driven member 22 and the second driven member 23 to rotate; the rotation plane of the active member 24 is perpendicular to the rotation plane of the first driven member 22.

[0066] It should be noted that an arc plate 241 is provided on the outer ring of one side of the active member 24 relative to the support rod 242; and the arc plate 241 is a semi-arc structure. When the active member 24 is in the rotation process, when the lever 243 drives the first follower 22 to rotate 90°, the arc plate 241 contacts the end face N of the first follower 22. During the rotation process, the arc plate 241 pushes the first follower 22 to reset, so that another group of first U-shaped grooves 221 rotates to the position of the previous group of first U-shaped grooves 221, so as to facilitate the active member 24 to rotate and drive the first follower 22 to rotate, and the angle of each rotation is 90°.

[0067] The active member 24 and the second driven member 23 are in mutually perpendicular planes; the rotation of the active member 24 can drive the first driven member 22 to rotate; and the active member 24 can simultaneously drive the first driven member 22 and the second driven member 23 to rotate during the rotation process.

[0068] Furthermore, the end of the rotating shaft 12 passes through the mixing barrel 11 and extends to the outside thereof, and the end of the rotating shaft 12 is connected to the second driven member 23; the second driven member 23 can drive the rotating shaft 12 to rotate coaxially.

[0069] It should be noted that the rotating shaft 12 is connected to the second follower 23, and the rotation of the second follower 23 can drive the rotating shaft 12 to rotate; the rotation of the rotating shaft 12 can also drive the feeding blade 13 to rotate; thereby, the raw materials are pushed along the inner wall of the mixing barrel 11 through the spiral feeding of the blades; and the raw materials can be continuously turned during the rotation of the feeding blade 13; further, the raw materials can be fully mixed.

[0070] Furthermore, the linkage shaft 14 passes through the second follower 23 and is connected to the first follower 22; the linkage shaft 14 also includes a protrusion 142 arranged on the side wall; the first follower 22 also includes an arc groove 222 arranged inside its shaft hole; the protrusion 142 is adapted to the arc groove 222, and the rotation of the first follower 22 can drive the linkage shaft 14 to move along its axial direction.

[0071] Specifically, the first follower 22 also rotates with the rotation of the active member 24; and an arc groove 222 is opened at the end of the first follower 22, and the arc groove 222 surrounds the inside of the first follower 22 to form a complete closed loop; the number of arc grooves 222 is n, and n is greater than or equal to 1; the protrusion 142 is adapted to the arc groove 222; the single arc groove 222 is preferably a curved groove structure, and during the rotation of the first follower 22, the protrusion 142 performs reciprocating linear motion along the inner wall of the arc groove 222, and at the same time, the movement of the linkage shaft 14 can drive the feed blade 13 to move back and forth; thereby, the blades of the feed blade 13 are used to continuously stir the raw materials, so that the raw materials can be fully mixed to ensure that the raw materials can be fully mixed.

[0072] It should be noted that the distance that the first follower 22 pushes the linkage shaft 14 to move horizontally is less than the distance that the feed blade 13 spirally feeds once; the distance that the feed blade 13 spirally feeds the material minus the distance that the feed blade 13 pushes the material to move horizontally is a positive number.

[0073] Furthermore, a fixed blade 121 is disposed on the outer side of the end of the rotating shaft 12 ; the feed blade 13 and the fixed blade 121 are separated by a set of baffles 113 .

[0074] It should be noted that the end of the rotating shaft 12 is connected to a fixed blade 121. When the raw material on the inner wall of the mixing barrel 11 moves from the discharge port opened by the baffle 113 to the other side of the baffle 113, the fixed blade 121 rotates to continue to transport the mixed raw material, thereby facilitating the normal operation of the injection molding machine.

[0075] When in use, the raw material enters the mixing barrel 11 from the feed port 111, and then the active member 24 is rotated. During the process of the active member 24 rotating half a circle, the outer wall of the lever 243 contacts the inner wall of the second U-shaped groove 231. The lever 243 drives the second driven member 23 to rotate during the rotation process. The second driven member 23 drives the rotating shaft 12 to rotate while the rotating shaft 12 rotates. The rotation of the rotating shaft 12 drives the feed blade 13 to rotate. The rotation of the feed blade 13 can transport the raw material to the side of the discharge port. Then the active member 24 rotates the remaining half a circle, and the outer wall of the lever 243 contacts the inner wall of the first U-shaped groove 221. At this time, the arc plate 241 conflicts with the end face M of the second driven member 23, and pushes the arc plate 241 to push the second driven member 23 Reset; the first follower 22 rotates to drive the protrusion 142 to reciprocate along the trajectory inside the arc groove 222 and along the axis of the feed blade 13; the feed blade 13 reciprocates and continuously moves the raw materials back and forth, thereby accelerating the further mixing of the raw materials; and during the process of the active member 24 driving the first follower 22 to rotate, the protrusion 142 can perform multiple reciprocating linear motions along the inner wall of the arc groove 222, thereby fully mixing the raw materials; through the cooperation between the second follower 23 and the rotating shaft 12, and the cooperation between the first follower 22 and the linkage shaft 14, when the feed blade 13 rotates a quarter of a turn, the feed blade 13 performs multiple reciprocating linear motions, which can fully mix the materials inside the mixing barrel 11.

[0076] In summary, through the cooperation between the transmission unit 2 and the feed blade 13, in the process of driving the feed blade 13 to rotate, the feed blade 13 can be driven to move back and forth in a straight line direction; thereby, the feed blade 13 can be used to push the raw materials to move back and forth; and then the raw materials can be fully mixed, and the mixed raw materials can be transported.

[0086] The optimized clamping unit of the injection molding machine increases the template spacing, provides more mold application options, improves mold strength, and extends the service life of the mold.

[0087] The coordinated work of these components enables the injection molding machine to efficiently and stably produce a variety of plastic products to meet the needs of different industries. Through intelligent control systems and optimized mechanical design, the injection molding machine not only improves production efficiency, but also ensures product quality and precision.

[0088] The production process of the injection molding machine begins with the initialization setting of the electronic control unit, in which key parameters such as temperature control, injection pressure and injection speed are carefully adjusted to adapt to specific plastic raw materials and product requirements; then, the clamping unit 31 is quickly started, and the mold is closed under the action of a strong clamping force to ensure mold stability during the injection process; in the pre-plasticization stage, the injection unit 32 heats and plasticizes the plastic raw material and transforms it into a molten state to prepare for injection; then, the molten plastic is quickly and accurately injected into the mold cavity through precise injection metering and high-pressure injection systems to achieve efficient injection; in the pressure holding stage, the injection unit 32 continues to apply pressure to compact the melt, increase density, and replenish The cooling system then intervenes to quickly and evenly remove the heat from the mold, allowing the molded part to cool and solidify, ensuring dimensional stability and strength compliance. Once the plastic part is completely solidified, the clamping unit 31 controls the mold to open, and the ejection mechanism pushes out the molded plastic part, and the operator or the automated system takes out the plastic part for subsequent inspection and processing. After completing these steps, the injection molding machine restarts the cycle and continues production. Throughout the process, the intelligent electronic control unit monitors production parameters in real time, and the optimized clamping unit, injection trolley, high-mix screw and other components work together to ensure the efficiency and stability of the injection molding process and meet the needs of different industries for plastic products.
