[0048] A rotating sleeve 54 is rotatably connected to the sliding cylinder 53 located at the innermost side of the sleeve;

[0049] When using, Figure 3 As shown, the raw material for plastic injection molding is continuously introduced into the connecting pipe 44, the connecting pipe 44 is connected to the rotating cavity 42, and then the injection molding raw material enters the rotating cavity 42, the rotating cavity 42 is connected to the injection molding cylinder 41, and the injection molding raw material enters the injection molding cylinder 41, and the telescopic mechanism 51 is started. The telescopic mechanism 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 51 drives the lifting plate 52 to move, and the lifting plate 52 drives the corresponding sliding cylinder 53 to move, so that the multiple sliding cylinders 53 slide against each other, and the processing is performed as needed. The thickness of the spherical plastic is adjusted by adjusting the thickness of the outermost side of the plurality of sliding cylinders 53 located at the lower side, that is, by starting the telescopic mechanism 51, the sliding cylinder 53 located at the outer side is raised or lowered, and the plurality of sliding cylinders 53 are moved from the outer side to the inner side in sequence, that is, the outermost sliding cylinder 53 is driven to move first, so that the sliding cylinder 53 moves upward, so that the lower end of the sliding cylinder 53 moves to the upper side, and then when the injection molding material passes through the lower end of the injection molding cylinder 41, the inner side of the injection molding material contacts the second sliding cylinder 53, so as to adjust the thickness of the injection molding material when it is discharged;
