S8: then, the movable rack (1006) at the outer side of the upper die holder (2) is meshed with the driven gear (1005) for transmission, and then the screw (1001) is driven to rotate reversely, so that the sleeve (1002) moves back along the axial direction of the screw (1001), in the process, the sliding rod (162) moves along the transverse groove at the upper side of the movable groove (161) and then enters the inclined groove, the third elastic telescopic rod (164) is extruded and finally enters the transverse groove at the lower side of the movable groove through the inclined groove, at the moment, the sleeve (1002) pushes the stressed plate (6041) at the end part of the movable plate (604) to abut against, the stressed plate (6041) is stressed to drive the movable plate (604) to move on the transverse plate (602), the first elastic telescopic rod (603) is compressed, the inserting rod (606) moves out of the slot (12) of the movable frame (7) through the second elastic telescopic rod (605), the placing tube (701) connected with the movable frame (7) is not limited any more, the compressed first elastic element (901) drives the placing tube (701) to move back through the pushing seat (902), so that the placing tube (701) moves back on the transverse plate (602) to drive the insert rod (606) to move, and the release agent (8) to be reset for preparing a cavity for a repeated injection.
