[0027] The sliding assembly 12 includes a maintenance slide rail 121 and a maintenance slider 122 matching the maintenance slide rail 121. The maintenance slide rail 121 is fixedly connected to the support platform 11. The extension direction of the maintenance slide rail 121 is the same as the extension direction of the support platform 11. The maintenance slide rail 121 and the maintenance slider 122 are slidably connected. The maintenance slider 122 is rotatably connected to the support seat 13. The straight line where the maintenance slide rail 121 is located and the straight line where the movable slide rail 41 is located are not perpendicular to each other.

[0028] The maintenance slider 122 has a locking piece 123 for fixing the position of the maintenance slider 122. The locking piece 123 can be a threaded connection piece, or a locking mechanism such as a cam handle. The locking piece 123 is used to fix the maintenance slider 122 so that it cannot move freely along the maintenance slide rail 12, thereby increasing stability during the injection process.

[0029] like Figure 3 As shown, the pneumatic unit 2 includes a pneumatic component 21 and a connecting plate 22. The connecting plate 22 is rotatably connected to the output end of the pneumatic component 21, and there is a vertically movable gap between the connecting plate 22 and the pneumatic component 21.

[0030] The pneumatic assembly 21 includes a pneumatic seat 211 and a plurality of nozzles 212. The pneumatic seat 211 is fixedly connected to the second movable slider 43.
