[0008] As an optimization, the first cylinder is a cylinder with a guide rod.

[0009] As an optimization, at least three nozzles are evenly arranged at the bottom of the vertical plate.

[0010] As an optimization, two guide sleeves are respectively provided on both sides of the movable die, and a guide rod is further provided between the front bottom plate and the rear bottom plate, and the guide sleeve is installed on the guide rod.
