Four guide holes 9 are formed on the movable mould plate 2, and the guide holes 9 are also formed at the corresponding positions of the longitudinal plates 102.

The outer surface of the movable template 2 is provided with a plurality of moulds 10, for example, six moulds 10, the outer contour of each mould 10 is the inner contour of the shell, each mould 10 is of a hollow structure, a plurality of push rods 11 are arranged on the push plate 6, each mould 10 is matched with four push rods 11, through holes 12 are formed in the corresponding positions of the movable template 2 and the moulds 10, and the push rods 11 are pushed forwards and then pass through the through holes 12 to just abut against four corners of the shell. Six cavities 13 are formed in the static template 3 corresponding to the dies 10, the six cavities 13 are one turn larger than the six dies 10, and when the dies 10 are inserted into the cavities 13, the space between the dies 10 and the cavities 13 is the wall thickness of the shell.

The die cavity 13 is closed-ended, the bottom of the die cavity is provided with a material injection through hole 14, the outer side of the bottom, namely, the side facing the static die mounting plate 4 is provided with a material injection channel 15, the material injection channel 15 is in an inverted V shape formed by three transverse lines and one vertical line, the tail ends of the three transverse lines are communicated with the material injection through hole 14, and the material injection hole 16 is arranged at the position of the static die mounting plate 4 corresponding to the cross-shaped intersection of the three transverse lines and the vertical line.
