[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figure 1 As shown, the adjustable mold height clamp provided in this embodiment includes a clamp body 3. The bottom of the clamp body 3 is connected to a lifting base, which can adjust the height of the clamp, allowing it to accommodate more mold sizes and making it more versatile. Handles 4 are installed on both sides of the clamp body 3 for easy handling. A pressure block 7 is movably installed on the top of the clamp body 3. One end of the pressure block 7 has a pressure plate assembly, and a first rotating shaft 15 is installed on the end of the pressure block 7 near the pressure plate assembly. An end seat 5 is installed at a corresponding position on the top of the clamp body 3. The pressure block 7 is rotatably connected to the end seat 5 through the first rotating shaft 15. The other end of the pressure block 7 is rotatably connected to the piston rod 8 of the hydraulic cylinder on the clamp body 3 through a second rotating shaft 16. Thus, the lifting and lowering of the pressure plate 6 can drive the pressure block 7 to rotate along the first rotating shaft 15, generating downward pressure on the end with the pressure plate 6 for clamping the mold.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the pressure block 7 has a slot on one end where the pressure plate assembly is installed, and two positioning rods 11 are provided in the slot. The pressure plate assembly includes multiple pressure plates 6. The pressure plates 6 have insertion holes 12 at positions corresponding to the positioning rods 11. The pressure plates 6 are fixed by combining the pressure plates 6 with the positioning rods 11 and then fixing them with nuts 10. The pressure plates 6 include multiple plates of different grades, which are installed from high to low. A pad 9 is provided between the nut 10 and the outermost pressure plate 6 to reduce damage to the surface of the pressure plate 6 when installing the nut 10. The pressure plates 6 are fixed by the nut 10, which is simple and convenient to operate and facilitates the replacement of damaged pressure plates 6. At the same time, the pressure plates 6 can also be selected with different grades of plates according to actual needs, making them more suitable for different molds.

[0027] In this embodiment, as Figure 5 and Figure 6 As shown, the bottom of the mold clamping body 3 is provided with a mounting groove 13. The lifting base includes a mounting seat 1 and a telescopic rod 2 mounted on the mounting seat 1. The output end of the telescopic rod 2 is connected to a mounting plate 14 that cooperates with the mounting groove 13. The telescopic rod 2 is a hydraulic telescopic cylinder. By lifting the mold clamping body, the appropriate height can be selected for molds of different sizes, making it more convenient to use.

[0028] In summary, in this embodiment, the adjustable mold height clamping device, by setting the positioning rod 11 and the pressure plate 6 fixed thereon by the nut 10, allows for more flexible adjustment of the size of the pressure plate 6 during installation. At the same time, the pressure plate 6 can be quickly and conveniently replaced during clamping, thereby improving the efficiency and stability of clamping.
