[0031] Specifically, in this utility model, when the hydraulic cylinder 112 is working, it pushes the second connecting plate 114 to move vertically, thereby changing the height of the mounting groove 115. By adjusting the height of different mounting grooves 115, the mounting groove 115 can form different structures with the second connecting plate 114, allowing different sizes of lower cavity plates 116 to be installed on the lower molding assembly 11. When the servo electric cylinder 4 is working, it pushes the molding template assembly 5 to move vertically, thereby achieving the purpose of adjusting the height of the molding template assembly 5. When the cylinder 8 is working, it pushes the first connecting plate 9 to move. Through the transmission of the first connecting plate 9, the... The height of the upper cavity plate 10 can be finely adjusted. When the servo motor 52 is working, it drives the first transmission wheel 53 to rotate. Through the transmission belt 56, the second transmission wheel 55 also rotates.
