[0026] Reference Figure 1 、 Figure 4 、 Figure 5The telescopic assembly includes a small telescopic rod 12, which is located on the inner bottom wall of the cylindrical tank 2. The small telescopic rod 12 is cylindrical and is located on the inner bottom wall of the cylindrical tank 2. It is designed to be telescopic in the vertical direction so as to flexibly adjust the height of the mold. The top of the small telescopic rod 12 is fixedly connected to a support plate 11. The support plate 11 is a flat rectangular plate fixedly connected to the top of the small telescopic rod 12 to ensure that the support assembly can evenly distribute force. The top of the support plate 11 is fixedly connected to the bottom of the support column 4. The inside of the base 1 is fixedly connected to a through column 13. The through column 13 is a long cylindrical shape that runs through the inside of the base 1. The external thread of the through column 13 is connected to two extrusion columns 14. The two extrusion columns 14 are both located on the external thread connection of the through column 13, allowing independent adjustment. The front side of the through column 13 is fixedly connected There is a handle 24, and a placement slot 15 is provided on the top of the two extrusion columns 14. A spring 16 is fixedly connected to the outside of the through-column 13.

The rebounder 23 is located on the outside of the long rod 20.

[0027] Working principle: When using the mold, the mixed material is placed into the interior of the loading tray 3 and pressed. When pressed, the material will be shaped by the shape inside the loading tray 3. After the loading tray 3 is pressed and shaped, when the pressure is increased to reduce the thickness of the shaping, the loading tray 3 will press the buffer tray 5, and the buffer tray 5 will support the loading tray 3 being pressed. At the same time, the support column 4 will press down. When the support column 4 is pressed down, the arc buckle 6 will press down the positioning block 8, and the arc groove 10 will elastically move outward through the elastic ring 9. When the top of the support column 4 expands, the arc buckle 6 will be stuck in the inside of the arc groove 10. Its purpose is to support the pressure capacity of the top. When the pressure capacity is increased again, the arc buckle 6 will fall off. At the same time, the arc buckle 6 near the top of the support column 4 will be stuck in the inside of the arc groove 10 again. Its function is to adjust the plastic thickness through different pressure forces, which is convenient for the use of the device. After the molding, the small telescopic rod 12 will lift the support column 4 through the support plate 11, and the structure after the internal work is completed will be returned to its place;

[0028] The cylindrical can 2 is fixed in the placement groove 15 on the top of the base 1 by rotating the through-column 13 and the two extrusion columns 14 inside it are fitted together to prevent the cylindrical can 2 from being deflected when pressed. When the sleeve handle 24 is rotated again in the opposite direction, the through-column 13 drives the spring 16 to quickly separate the extrusion columns 14, making it convenient to take out the cylindrical can 2. The top plate 19 is rotated on the top of the base 1 through the movable column 17. When the long rod 20 is pressed downward, the rebounder 23 begins to compress and the circular cover 21 at the bottom covers the top of the cylindrical can 2. When the long rod 20 is rotated, it can be separated from the circular cover 21. At the same time, the compressed rebounder 23 will exert force on the obstruction ring 22 to return it to its original position, saving the time of sorting after use.
