[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The technical solution of the present application is a plastic bottle injection molding device that is convenient for unloading. When the hydraulic cylinder drives the movable mold to move outward, it can drive the push rod to push the piston to move in the sleeve, so as to introduce gas into the inner cavity of the first conduit, and the gas enters the vertical pipe and then enters the second conduit, so that the plastic bottle in the mold cavity of the fixed mold can be blown away by the gas in the second conduit, thereby realizing automatic unloading, improving the convenience of unloading, and reducing energy consumption without the need for other energy sources;

[0019] The blown-off plastic bottles can fall between the fixed mold and the movable mold, and then fall onto the surface of the conveyor belt, so that the conveyor belt can be used to transfer the plastic bottles after being removed, thereby further improving the convenience of operation without the need for manual transfer of plastic bottles.

[0029] In actual use, the hydraulic cylinder 15 is started to drive the movable mold 12 to move, so that the fixed mold 11 and the movable mold 12 can be closed, and then the raw materials are introduced into the fixed mold 11 and the movable mold 12 to realize the molding of the plastic bottle. After the plastic bottle is molded, the hydraulic cylinder 15 is started to drive the movable mold 12 to move outward. When the movable mold 12 moves, it will drive the push rod 33 to push the piston 31 to move in the sleeve 3, so that the gas can be introduced into the first conduit 22, so that the gas enters the vertical pipe 21, and then the gas enters the mold cavity of the fixed mold 11 along the second conduit 2, and the plastic bottle is blown away to realize automatic unloading;

[0030] Furthermore, a side wall of the sleeve 3 is fixedly connected to an air inlet valve 35. The setting of the air inlet valve 35 allows gas to enter the sleeve 3 when the piston 31 moves toward the fixed mold 11, thereby ensuring air pressure balance.

[0031] Furthermore, holes 32 are provided on both sides of one end of the sleeve 3 corresponding to the movable mold 12. The arrangement of the holes 32 further ensures the air pressure balance when the piston 31 moves.

[0032] It is worth mentioning that the four corners of one side wall of the fixed mold 11 are all fixed with limiting rods 13, the limiting rods 13 movably penetrate the movable mold 12 and are fixedly connected to the support plate 14.

After the plastic bottle is molded, the hydraulic cylinder 15 is started to drive the movable mold 12 to move outward. When the movable mold 12 moves, it will drive the push rod 33 to push the piston 31 to move in the sleeve 3, so that the gas can be introduced into the first conduit 22, so that the gas enters the vertical pipe 21, and then the gas enters the mold cavity of the fixed mold 11 along the second conduit 2, and the plastic bottle is blown away to realize automatic unloading. The plastic bottle after unloading falls onto the surface of the conveyor belt 16, so that the plastic bottle can be transferred to the outside for collection, which further improves the convenience of operation.
