[0003] In summary, this application proposes an injection guide structure for an injection molding machine to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an injection guide structure for an injection molding machine, which can solve the problem that in some existing injection molding machines, the injection port is usually fixed, which easily leads to uneven pressure distribution during injection, thereby affecting the injection accuracy of the injection molding machine and reducing the quality of mold injection.

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: an injection guide structure for an injection molding machine, including a mounting frame 1 and an adjusting guide assembly. The injection molding machine body 2 is mounted on the mounting frame 1. A mounting plate 6 is fixedly connected to one side of the mounting frame 1, and an electric push rod 5 is fixedly connected to the mounting plate 6. This arrangement facilitates the sliding action of the adjusting guide assembly. The adjusting guide assembly is located on the mounting frame 1 and includes an auxiliary rod 3, a sliding block 4, a connecting flange 7, a connecting piece 8, a U-shaped plate 9, a rotating sleeve 10, and a threaded rod 11. The auxiliary rod 3 is fixedly connected between the inner walls of both sides of the mounting frame 1. A sliding block 4 is slidably mounted on the auxiliary rod 3. U-shaped plates 9 are fixedly connected to the front and rear sides of the sliding block 4. The threaded rod 11 is arranged in two sets facing each other, threadedly mounted on the U-shaped plate 9. A rotating sleeve 10 is rotatably mounted on the top of the threaded rod 11. The connecting flange 7 is arranged in two sets, distributed vertically. The connecting flange 7 is located on the outer wall of the injection molding machine body 2 and connected by the connecting piece 8. The bottom of the connecting piece 8 is secured... Installed on the top of the rotating sleeve 10, during use, the operator manually turns the threaded rod 11, causing it to rotate. The rotation of the threaded rod 11 drives the rotating sleeve 10 to move upward, which in turn drives the connecting piece 8 to move upward. The connecting piece 8 then drives the connecting flange 7 to move upward, which in turn drives the injection machine body 2 to move upward. Simultaneously, one end of the injection machine body 2 moves on the auxiliary block 12, facilitating the adjustment of the injection direction. Through the coordinated use of the auxiliary rod 3, sliding block 4, connecting flange 7, connecting piece 8, U-shaped plate 9, rotating sleeve 10, and threaded rod 11, the mold can be kept in the correct alignment position during injection, effectively avoiding mold offset or uneven pressure distribution. This reduces injection defects caused by poor mold alignment. Furthermore, by adjusting the injection port position of the injection molding machine, the direction and speed of plastic flow can be controlled more precisely, ensuring more uniform pressure and speed during injection, which helps improve production efficiency.

[0019] Furthermore, an auxiliary block 12 is slidably mounted on the auxiliary rod 3, and one side of the injection machine body 2 is slidably mounted on the auxiliary block 12. The free end of the mounting plate 6 is connected to the auxiliary block 12, which facilitates the electric push rod 5 to drive the injection machine body 2 to slide. A fixing member 13 is fixedly connected to one side of the mounting frame 1. One end of the fixing member 13 is connected to the auxiliary block 12, which facilitates the stable operation of the injection machine body 2. The fixing member 13 consists of a fixing plate and a fixing rod. An injection port is opened on the other side of the mounting frame 1, which facilitates the injection operation of the injection machine body 2.

[0020] Working principle: During use, the operator manually turns the threaded rod 11, causing it to rotate. The rotation of the threaded rod 11 drives the rotating sleeve 10 to move upward. The movement of the rotating sleeve 10 drives the connecting piece 8 to move upward. The connecting piece 8 drives the connecting flange 7 to move upward. The connecting flange 7 drives the injection machine body 2 to move upward. At the same time, one end of the injection machine body 2 moves on the auxiliary block 12, which facilitates the adjustment of the injection direction of the injection machine body 2.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
