[0040] The insertion slot 27 is fixedly connected with a vertical ejector pin, and the insertion slot 27 is connected with the internal cavity of the lower mold shell 2.

[0041] The working principle of the present application is as follows: after injection is completed, water enters the heat dissipation pipe 152 and the second connecting elbow 222 through the first liquid inlet pipe 151 and the second liquid inlet pipe 221 respectively, and the water flow in the heat dissipation pipe 152 and the second connecting elbow 222 carries away the heat on the upper mold shell 1 and the lower mold shell 2, so that the injection molding part is rapidly cooled;

[0042] The water in the heat dissipation pipe 152 enters the liquid storage pipe 154 through the first connecting elbow 153 and cannot be discharged, and the pressure becomes higher and higher. When the pressure in the liquid storage pipe 154 reaches a preset value, the water in the liquid storage pipe 154 is sprayed out from the pressure relief valve 155 and sprayed to the lower part inside the upper mold shell 1, so that the water is in large area contact with the inside of the upper mold shell 1 and carries away the heat of the upper mold shell 1. Part of the water is evaporated by the heat. The connecting pipe 11 draws the air inside the upper mold shell 1 through the air suction assembly, so that the evaporated gas is discharged from the connecting pipe 11, so that the inside of the upper mold shell 1 is under negative pressure, and the external air enters the inside of the upper mold shell 1 from the air inlet hole 12, so that the airflow is in the inside of the upper mold shell 1 after entering the inside of the upper mold shell 1. The upper mold shell 1 is cooled again to accelerate the cooling speed of the upper mold shell 1 and improve the cooling efficiency of the television set shell 3;

[0043] The liquid sprayed out of the liquid storage pipe 154 falls on the triangular plate 13 or the convex plate 156. The liquid on the convex plate 156 flows to the triangular plate 13 along the convex surface. The liquid flows to the liquid collecting groove 14 along the inclined surface of the triangular plate 13 and enters the liquid storage cavity 165. When the upper mold shell 1 and the lower mold shell 2 are combined, the vertical ejector pin in the slot 27 drives the sliding block 164 to rise, so that the sliding block 164 is located above the liquid storage cavity 165, the outer expansion cavity 166 is exposed, and the liquid in the liquid storage cavity 165 flows into the slot 27 through the outer expansion cavity 166 and enters the inside of the lower mold shell 2;

[0044] The water in the second connecting elbow 222 finally enters the connecting hose 231, and then is discharged from the liquid outlet pipe 233. When the cooling is about to end, the liquid outlet pipe 233 stops discharging liquid, the valve body 235 is opened, the water in the connecting hose 231 enters the inside of the liquid storage pipe 234, and finally the water flow is blocked by the block 238. The continuous water injection makes the water pressure become larger, the water pressure pushes the block 238 to move, when the block 238 moves below the fixed column 251, the leakage storage tank 252 is through the through part of the liquid storage pipe 234, the water is released instantaneously, and is injected into the leakage storage tank 252. The water quickly pushes the circular plate 255 to rise, the circular plate 255 drives the hammering plate 256 to rise through the connecting rod, the hammering plate 256 hammers the inside of the lower mold shell 2, the vibration of the hammering makes the injection molding part and the lower mold shell 2 separate. When the leakage storage tank 252 is filled with water, the pressure continues to increase, the block 238 continues to move, to the position of the block 238 moving to the rough pipe 239, the rough pipe 239 is exposed, the water flows out from the rough pipe 239, and finally flows out from the liquid outlet hole 26, and then is discharged from the liquid outlet pipe 21. The water entering the slot 27 falls on the inclined plate 24, and is discharged from the liquid outlet pipe 21 along the inclined surface of the inclined plate 24. When the water pressure becomes smaller, the block 238 is pulled back to the original position by the second spring 237, the rough pipe 239 is blocked by the block 238, and the water cannot be discharged. At this time, the water injection is terminated, the water valve in the liquid outlet pipe 233 is opened, the water in the liquid storage pipe 234 and the leakage storage tank 252 is pumped out, and the circular plate 255 is pulled back to the original position by the third spring 254.

The protection scope of the present application is defined by the claims.
