[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-3 The present invention provides an embodiment of an injection mold locking mechanism, comprising a mold body 1, the mold body 1 comprising an upper mold body 2, a mold box 3 and a lower mold body 4, the mold box 3 being installed and fixed in the middle of the upper mold body 2 and the lower mold body 4, the upper mold body 2, the mold box 3 and the lower mold body 4 being fixed together by a limiting locking mechanism, the limiting locking mechanism comprising a lateral limiting plate 6, a limiting pin 8, a stop block 9 and a limiting strip 10.

[0021] Furthermore, the upper mold body 2 and the mold box 3 are fixedly connected by a lateral limiting plate 6. There are two lateral limiting plates 6, and the surface of the lateral limiting plate 6 is provided with screw fixing slots 5. By setting the lateral limiting plate 6 in conjunction with the screw assembly, it is convenient to reinforce the connection and limit the fixation between the upper mold body 2 and the mold box 3.

[0022] Furthermore, one end of the limiting pin 8 is connected to the two side surfaces of the mold box 3 via the movable shaft 11. The two side surfaces of the mold box 3 are equipped with fixed handles 7, which are convenient for picking up and fixing the mold box 3.

[0023] Furthermore, the stop block 9 is installed and fixed on the outer surface of the lower mold body 4, and the other end of the limiting pin 8 contacts the upper surface of the stop block 9. The limiting strip 10 is installed on one side of the stop block 9. The limiting strip 10 is used to limit and fix the limiting pin 8. The limiting strip 10 is fixedly connected to the outer surfaces of the upper mold body 2 and the lower mold body 4 respectively by screw assembly, so that the limiting strip 10 can be quickly installed and fixed. By setting the structure of the limiting pin 8, the stop block 9 and the limiting strip 10, the limiting pin 8 cannot rotate due to the limiting block 9 and the limiting strip 10, so as to facilitate further locking of the two sides of the mold box 3.

[0024] Furthermore, the surface of the mold box 3 is provided with positioning slots 14. The upper mold body 2 is fixedly connected to the lower mold body 4 through the positioning guide post 12 passing through the positioning slots 14, which facilitates the precise alignment and installation of the upper mold body 2, the mold box 3 and the lower mold body 4.

[0025] Furthermore, the mold box 3 is provided with an injection molding groove 15 inside for injection molding of the product. The mold box 3 has fixed slots 16 at both ends. The two ends of the upper mold body 2 are fixed to the fixed slots 16 by the engaging parts 13, so that the upper mold body 2 and the mold box 3 can be further engaged and fixed.

[0026] Working Principle: During use, the upper mold body 2, mold box 3, and lower mold body 4 are fixed together by a limiting and locking mechanism. This mechanism includes a lateral limiting plate 6, a limiting pin 8, a stop block 9, and a limiting strip 10. The stop block 9 is fixed to the outer surface of the lower mold body 4. The other end of the limiting pin 8 contacts the upper surface of the stop block 9. The limiting strip 10 is installed on one side of the stop block 9 and is used to limit and fix the limiting pin 8. The limiting strip 10 is fixedly connected to the outer surfaces of the upper mold body 2 and the lower mold body 4 respectively by screw assemblies, allowing for quick installation and fixation. By setting the structure of the limiting pin 8, stop block 9, and limiting strip 10, the limiting pin 8 is prevented from rotating by the limiting obstruction of the stop block 9 and the limiting strip 10. To facilitate further locking of the two side surfaces of the mold box 3, the upper mold body 2 and the mold box 3 are fixedly connected by lateral limiting plates 6. There are two lateral limiting plates 6, and the surface of the lateral limiting plates 6 is provided with screw fixing slots 5. By setting the lateral limiting plates 6 in conjunction with the screw assembly, it is convenient to reinforce the connection and limit the fixation between the upper mold body 2 and the mold box 3. By using a convenient assembly and fixing limiting locking mechanism to lock and fix the upper mold body 2, the mold box 3 and the lower mold body 4 inside the mold, the components can be quickly and accurately aligned and installed, which facilitates the firm locking and safety protection of the mold box 3. This can further ensure the safety and stability of the mold body 1 during injection molding and improve the product shaping quality in the injection molding groove 15 inside the mold box 3.
