The inner wall of the rectangular spring port is fixedly connected with a vertical guide post 24. The vertical guide post The outer side wall of 24 is sleeved with a spring slider 25. The spring slider 25 passes through a compression spring and a rectangular spring port sleeved on the outer side wall of the vertical guide post 24. The compression spring will exert downward pressure on the spring slider 25, thereby The injection molding chassis 10 connected with it through the rotating shaft 26 can always have downward pressure to ensure the sealing effect with the injection mold cavity 5. The spring slider 25 is fixedly connected with the rotating shaft 26, and the adjustment rotating shaft 9 opens There is a rotating hole that is sleeved with the rotating shaft 26, so that the injection-molded chassis 10 connected with the adjustment rotating shaft 9 can rotate relatively, so that when the buoyancy air ring 11 on it is at the bottom of the water, different buoyancy is generated to drive the injection-molded chassis 10 to rotate. , to achieve the effect of demoulding the injection-molded chassis 10 .

An injection molding chassis 10 is fixedly connected to the bottom of the adjusting shaft 9, the bottom of the injection molding chassis 10 is arranged in a trapezoid shape, and the outer side wall of the injection molding chassis 10 is provided with a sealing rubber ring 33 for packaging sealing; the injection molding chassis 10 is provided with a driving injection molding chassis 10. The rotating buoyancy air ring 11, wherein when the injection mold plate 4 moves downward, driving the buoyancy air ring 11 to move downward, the buoyancy generated by the buoyancy air ring 11 will be applied to the upper and lower ends of the injection mold plate 4. Forces of different sizes, Thereby, the injection mold plate 4 is rotated, and the outer wall of the injection mold plate 4 is provided with a liquid-displacing component that drives the cooling liquid to flow; The inner wall of the shaped mouth is rotatably connected with a driving blade 28 through a rotation shaft 27, one end of the rotation shaft 27 extends outward through the side wall of the arc-shaped mouth, and is fixedly connected with a rotation gear 29, and a drive rack that meshes with the rotation gear 29 is provided below the support. 30. When the injection mold plate 4 is rotating, when the rotation gear 29 moves to the driving rack 30, the rotation gear 29 will rotate under the resistance of the driving gear 30, so as to realize the effect of the driving blade 28 to move the coolant.

Specifically, when the present invention is performing injection molding to produce plastic cylinders, the working process is that the driving gear 12 under the action of the servo motor will make the driving gear ring 13 drive the injection mold plate 4 to rotate. When the injection mold plate 4 rotates to the top, The injection molding chassis 10 that is under the pressure of the compression spring will close the opening of the injection molding cavity 5, and at the same time, the injection hole 32 opened on the injection molding plate 4 and the injection channel 31 provided on the support shaft 3 are located. In the through state, at this time, the injection molding machine will inject the hot-melt polyethylene raw material into the injection mold cavity 5 opened on the injection mold plate 4 through the injection hole 32, and gradually form in the injection mold cavity 5;

When the injection mold plate 4 rotates, the injection material in the upper injection mold cavity 5 and the injection mold chassis 10 on it move. When the injection mold plate 10 is driven by the injection mold plate 4 to move, it will make The collar 20 connected to it by the driving column 19 moves on the arc-shaped extension ring 7, and when the collar 20 is moved, the pneumatic piston block 23 connected to it through the arc-shaped return column 21 is pneumatically driven. Move in the compression port 22 to realize compressed air;

When the lower injection molding chassis 10 is driven by the injection molding mold plate 4 to move into the cooling pool 1 and is immersed in the cooling liquid, the water depth at the bottom of the buoyancy air ring 11 disposed on the injection molding chassis 10 is deeper, and the buoyancy force is opposite to the buoyancy force. The acting force of the air ring 11 is different, so that the buoyancy air ring 11 located in the deep water is subjected to greater buoyancy, and under the repulsion of the buoyancy, the injection-molded chassis 10 is driven to rotate with the rotating shaft 26 as the axis. At this time, The injection molding chassis 10 that was originally blocked by the injection molding cavity 5 will be separated from the injection molding cavity 5 due to the rotational force, and will be collided by the side wall of the opening of the injection molding cavity 5, which will generate pressure on the compression spring, and the spring slider 25 will generate pressure. The relative movement occurs. Since the blocking force of the injection mold cavity 5 to the injection molding chassis 10 is cancelled, the injection molding chassis 10 will return to the top of the injection mold plate 4 again under the action of the compressed gas in the pneumatic compression port 22, and the latter one The injection mold cavity 5 is docked, and so on;

When the injection mold plate 4 is moved into the cooling liquid, the plastic cylinder in the injection mold cavity 5 will be cooled.

When the injection mold plate 4 moves to the left side of the cooling pool 1 , at this time, because the distance between the spherical interference port 14 and the injection mold plate 4 gradually increases, under the action of the interference ball 16 , it will pass through the guide column 15 . The connected outer template 6 located on both sides of the injection mold cavity 5 is gradually moved outward to both sides. When moving outward, the plastic cylinder located in the injection mold cavity 5 will be demolded. At this time, due to the outer template The outward movement of 6 will allow a large amount of cooling liquid to enter the plastic cylinder, and gradually concentrate in the area between the plastic cylinder and the injection mold plate 4, the entry of the cooling liquid will realize the separation of the injection mold plate 4 and the plastic cylinder. When the injection mold plate 4 drives the plastic cylinder out of the cooling liquid in the cooling pool 1, the buoyancy of the cooling liquid to the plastic cylinder will be continuously reduced, and the cooling liquid between the injection mold plate 4 and the plastic cylinder will When gravity is applied to the plastic cylinder, when the buoyancy is less than gravity, the plastic cylinder in the injection mold plate 4 will fall freely into the cooling pool 1 under the lubrication of gravity and the cooling liquid;

When the plastic cylinder falls into the cooling pool 1, the autorotation gear 29 is driven to rotate under the action of the driving rack 30, thereby causing the driving blade 28 disposed in the injection mold plate 4 to rotate, cooling the cooling The liquid in the pool 1 is moved, and the plastic cylinder floating on the liquid surface will be moved to one side of the cooling pool 1 under the action of the waves on the cooling liquid. At this time, the worker only needs to collect it on one side.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or change of the inventive concept thereof shall be included within the protection scope of the present invention.
