[0029] When in use, the heated preform is placed inside the movable mold 10, and then the second cylinder 13 is started to shrink, and then the movable mold 10 can be driven to move toward the fixed mold 5, so as to achieve the purpose of mold closing. After the movable mold 10 and the fixed mold 5 are closed, the first cylinder 12 is extended, and the first cylinder 12 drives the blow molding head 8 to move toward the preform, so that the blow molding head 8 is in close contact with the preform, and then the bottle blowing machine body 7 is operated, and then the blow molding head 8 can blow the preform with the cooperation of the connecting hose 9, so that the preform can be blown into a plastic bottle; after the blow molding is completed, the second cylinder 13 is extended to drive The movable mold 10 is away from the fixed mold 5. At this time, as the movable mold 10 moves, the plastic bottle inside the fixed mold 5 can be pushed with the cooperation of the second pushing mechanism 6, and then separated from the fixed mold 5, so that the plastic bottle will move with the movable mold 10. After the first pushing mechanism 4 contacts the mounting frame 1, as the movable mold 10 continues to move, the plastic bottle inside the movable mold 10 can be pushed out under the action of the first pushing mechanism 4, so that the plastic bottle is separated from the movable mold 10. In this way, when the blow-molded plastic bottle is taken out, there is no need to take it out manually, thereby reducing the labor intensity of workers and improving work efficiency.

[0030] Specifically, Figure 3 and Figure 5As shown, the first pushing mechanism 4 includes a first movable plate 401, a first connecting rod 402, a first pushing block 403 and a first spring 404. The first connecting rod 402 is slidably connected inside the movable mold 10, the front end of the first connecting rod 402 is fixedly connected to the first movable plate 401, the rear end of the first connecting rod 402 is fixedly connected to the first pushing block 403, and the circumferential surface of the first connecting rod 402 is provided with a first spring 404, one end of the first spring 404 is fixedly connected to the movable mold 10, and the other end of the first spring 404 is fixedly connected to the first movable plate 401.
