[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) A first cooling component is provided in the upper shell of the mold. After the water in the heat dissipation pipe enters the liquid storage pipe through the first connecting elbow, the pressure becomes higher and higher. When the pressure in the liquid storage pipe reaches a preset value, the water in the liquid storage pipe is ejected from the pressure relief valve, so that the water contacts the interior of the upper shell of the mold over a large area, taking away the heat of the upper shell of the mold. Part of the water is evaporated by the heat, taking away the heat. The connecting pipe extracts the air inside the upper shell of the mold through the exhaust component, and the external air enters the upper shell of the mold from the air inlet hole, and dissipates the heat of the upper shell of the mold again, thereby accelerating the cooling speed of the upper shell of the mold and improving the cooling efficiency of the TV housing. The liquid ejected from the liquid storage pipe falls on the triangular plate, and the liquid flows to the liquid collecting tank along the inclined surface of the triangular plate. The liquid in the liquid storage cavity flows into the slot through the external expansion cavity and then enters the interior of the lower shell of the mold. (2) The water in the second connecting elbow finally enters the connecting hose and is then discharged from the liquid outlet pipe. When the cooling is about to end, the liquid outlet pipe stops discharging, the valve body opens, and the water in the connecting hose enters the liquid storage pipe. Finally, the water flow is blocked by the block, so that the water pressure pushes the block to move. When the block moves to the bottom of the fixed column and leaks out of the connection between the liquid storage tank and the liquid storage pipe, the water is instantly released and rushes into the liquid storage tank. The water quickly pushes the circular plate up, and the circular plate drives the hammer plate to rise through the connecting rod. The hammer plate strikes the inside of the lower shell of the mold, so that the vibration of the striking can separate the injection molded part from the lower shell of the mold. When the liquid storage tank is filled with water, the pressure continues to increase, and the block continues to move until the block moves to the position of the thick pipe, exposing the thick pipe, and the water flows out of the thick pipe and finally flows out from the drainage hole and then discharged from the drainage pipe.

[0024] The hammer assembly 25 includes a fixed column 251 fixedly connected to the upper end of the liquid storage plate 232, a liquid storage tank 252 is arranged inside the fixed column 251, the liquid storage tank 252 is through-connected with the liquid storage pipe 234, a connecting cross bar 253 is fixedly connected to the lower part of the liquid storage tank 252, a circular plate 255 is slidably connected to the inside of the liquid storage tank 252, a third spring 254 is fixedly connected to one side of the circular plate 255, the other end of the third spring 254 is fixedly connected to one side of the connecting cross bar 253, and the upper end of the circular plate 255 is fixedly connected to the hammer plate 256 through a connecting rod.

[0025] A vertical ejector pin is fixedly connected inside the slot 27 , and the slot 27 is connected through the inside of the mold lower shell 2 .

[0026] Working principle of the present invention: After injection is completed, water enters the heat dissipation pipe 152 and the second connecting elbow pipe 222 through the first liquid inlet pipe 151 and the second liquid inlet pipe 221 respectively, and the water flows in the heat dissipation pipe 152 and the second connecting elbow pipe 222 to take away the heat on the mold upper shell 1 and the mold lower shell 2, so that the injection molded part is cooled quickly; After the water in the heat dissipation pipe 152 enters the liquid storage pipe 154 through the first connecting elbow 153, it cannot be discharged, and the pressure becomes higher and higher. When the pressure in the liquid storage pipe 154 reaches the 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 of the upper shell 1 of the mold, so that the water contacts the inside of the upper shell 1 of the mold over a large area, taking away the heat of the upper shell 1 of the mold, and part of the water is evaporated by the heat. The connecting pipe 11 extracts the air inside the upper shell 1 of the mold through the exhaust component, so that the evaporated gas is discharged from the connecting pipe 11, so that the upper shell 1 of the mold is under negative pressure, and the external air enters the upper shell 1 of the mold from the air inlet 12, so that the airflow dissipates heat to the upper shell 1 of the mold again after entering the upper shell 1 of the mold, thereby accelerating the cooling speed of the upper shell 1 of the mold and improving the cooling efficiency of the TV housing 3; The liquid sprayed from the liquid storage tube 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 tank 14 along the inclined surface of the triangular plate 13 and enters the liquid storage cavity 165. When the mold upper shell 1 and the mold lower shell 2 are combined, the vertical ejector in the slot 27 pushes the slider 164 up, so that the slider 164 is located above the liquid storage cavity 165, and the outer expansion cavity 166 is exposed. The liquid in the liquid storage cavity 165 flows into the slot 27 through the outer expansion cavity 166 and then enters the interior of the mold lower shell 2. The water in the second connecting elbow 222 finally enters the connecting hose 231 and is then discharged from the liquid outlet pipe 233. When the cooling is about to end, the liquid outlet pipe 233 stops discharging, the valve body 235 opens, and the water in the connecting hose 231 enters the liquid storage pipe 234. Finally, the water flow is blocked by the block 238. The continuous water injection increases the water pressure, and the water pressure pushes the block 238 to move. When the block 238 moves to the bottom of the fixed column 251 and leaks out of the connection between the liquid storage tank 252 and the liquid storage pipe 234, the water is instantly released and rushes into the liquid storage tank 252. The water quickly pushes the circular plate 255 up, and the circular plate 255 drives the hammer plate 256 to rise through the connecting rod. The hammer plate 256 strikes the inside of the lower shell 2 of the mold, so that the vibration of the striking can make the injection The plastic part is separated from the lower shell 2 of the mold. When the liquid storage tank 252 is filled with water, the pressure continues to increase, and the block 238 continues to move until the block 238 moves to the position of the thick pipe 239, exposing the thick pipe 239. Water flows out of the thick pipe 239 and finally flows out from the drainage hole 26, and then is discharged from the drainage pipe 21. The water entering the slot 27 falls on the inclined plate 24 and is discharged from the drainage pipe 21 along the inclined surface of the inclined plate 24. When the water pressure decreases, the block 238 is pulled back to its original position by the second spring 237, and the thick pipe 239 is blocked by the block 238, so that the water cannot be discharged. At this time, the water injection is stopped, the water stop valve in the liquid outlet pipe 233 is opened, and the water in the liquid storage pipe 234 and the liquid storage tank 252 is pumped out. The circular plate 255 is also pulled back to its original position by the third spring 254.

[0027] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
