A cross limiting block 1001 is provided at the bottom end of the pressing groove 10, and a cross limiting groove matching the cross limiting block 1001 is provided at the top end of the moving template 7. A driving mechanism for moving the moving rod 3 up and down is provided inside the mounting frame 1. Slide blocks 701 are provided on both sides of the moving template 7, and sliding grooves matching the slide blocks 701 are provided on the mounting frame 1 for limiting the horizontal and vertical movement of the moving template 7;

[0026] Combined with the attached Figure 1 , Figure 3, the driving mechanism includes a rotating shaft 12 horizontally arranged in the mounting frame 1. One end of the rotating shaft 12 extends outside the mounting frame 1 and is connected to a motor 11. A number of gears 4 are provided on the rotating shaft 12. The gears 4 are arranged in the mounting shell 2. A rack adapted to the gears 4 is provided on the outer wall of the moving rod 3. One side of the moving rod 3 opposite to the rack is tangent to the inner wall of the mounting shell 2.

[0027] A limiting plate 201 is provided at the top of the mounting shell 2. A through hole 202 is opened on the limiting plate 201. The limiting plate 201 prevents the moving rod 3 from being connected upward infinitely.

[0028] Combined with the attached Figure 3 , the moving rod 3, the connecting plate 5 and the pressing block 6 are interconnected. And a reserved port is provided at the top of the moving rod 3 for connecting the melted raw material and the feeding pipe by an external material extrusion device.
