Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4An injection mold for an agricultural vehicle rearview mirror comprises an injection bottom plate 1, an injection top plate 2 and an injection port 3. An injection top plate 2 is arranged above the injection bottom plate 1, and an injection port 3 is provided at the top of the injection top plate 2. The injection bottom plate 1 comprises a bottom plate body 11, a docking groove 12, a positioning rod 13, a side frame 14, a reduction motor 15, a threaded rod 16 and a balance rod 17. A docking groove 12 is arranged at the top of the bottom plate body 11, and the edge of the docking groove 12 is an arc surface for easy insertion. A positioning rod 13 is arranged on the outside of the docking groove 12, and the positioning rod There are four 13 located at the four corners of the bottom plate body 11, and side frames 14 are provided on both sides of the bottom plate body 11. The side frames 14 are fixedly connected to the bottom plate body 11. A reduction motor 15 is provided inside the side frames 14. The reduction motor 15 is fixedly installed inside the side frames 14. A threaded rod 16 is provided at the top of the reduction motor 15. A balance rod 17 is provided behind the threaded rod 16. A top cap is fixedly connected to the top of the threaded rod 16 and the balance rod 17. The top cap is used to limit the range of movement on the threaded rod 16 and the balance rod 17.

[0020] Furthermore, the injection molded top plate 2 includes a top plate body 21, an insert plate 22 and a side plate 23. The bottom end of the top plate body 21 is fixedly connected to the insert plate 22, and the two sides of the top plate body 21 are fixedly connected to the side plates 23. The side plates 23 are penetrated by the threaded rod 16 and are threadedly connected to the threaded rod 16. The side plates 23 are penetrated by the balance rod 17, and the side plates 23 are slidably connected to the balance rod 17. The top plate body 21 is penetrated by the positioning rod 13, and the top plate body 21 is slidably connected to the positioning rod 13.

[0021] Furthermore, the bottom ends of the positioning rods 13 are fixedly mounted on the bottom plate 11, and every two positioning rods 13 are parallel to each other. At the same time, the positioning rods 13 and the balance rod 17 are parallel to each other. When the side plate 23 is lifted and lowered on the balance rod 17, the top plate 21 is lifted and lowered on the positioning rods 13 synchronously. The four positioning rods 13 penetrate the four corners of the bottom plate 11, so that the bottom plate 11 is lifted and lowered on the positioning rods 13 in unison, thereby avoiding the bottom plate 11 from being offset during the lifting process.

[0022] Furthermore, threaded holes and through holes are provided on the side plates 23, and the insert plates 22 are perpendicular to the top plate body 21. At the same time, there are four insert plates 22, the front and rear insert plates 22 are parallel to each other, and the left and right insert plates 22 are parallel to each other. The insert plates 22 can be respectively inserted into the docking grooves 12 to keep the position of the bottom plate body 11 fixed during the docking process with the top plate body 21 to avoid deviation.

[0023] Furthermore, the top end of the reduction motor 15 is connected to the threaded rod 16, and the reduction motor 15 can drive the threaded rod 16 to rotate. The threaded rod 16 and the balance rod 17 are parallel to each other. The balance rod 17 is fixedly inserted in the side frame 14. The balance rod 17 fixes the position. When the side plate 23 moves up and down on the threaded rod 16, the side plate 23 slides up and down on the balance rod 17 at the same time. The balance rod 17 is used to maintain the stability of the position of the side plate 23.

[0024] Working principle: The utility model is an injection mold for rearview mirror of agricultural vehicle. When in use, the threaded rod 16 is driven to rotate forward by starting the reduction motor 15, and the side plate 23 moves downward through the threaded connection with the threaded rod 16. At the same time, the side plate 23 moves downward on the balance rod 17, and the top plate 21 slides downward on the positioning rod 13, so that the bottom plate 11 and the top plate 21 are closed to each other, and the insertion plate 22 is synchronously inserted into the docking groove 12 to keep the bottom plate 11 and the top plate 21 fixed in position when they are closed. Carry out injection molding. After the object is formed, start the reduction motor 15 again to drive the threaded rod 16 to rotate in the opposite direction. The side plate 23 realizes upward movement through the threaded connection with the threaded rod 16. At the same time, the side plate 23 slides upward on the balance rod 17, and the top plate 21 slides upward on the positioning rod 13 to realize the separation of the top plate 21 and the bottom plate 11 from the mold, and always maintain the parallelism between the top plate 21 and the bottom plate 11, and maintain the stability of the position between the two, so as to avoid adverse effects such as scratches or collisions on the molded objects inside.
