[0068] Figure 20 777 is a clamping plate, which has a limiting hole 779, and 778 is a pot fixed to the clamping plate.

[0069] The working principle of the present invention includes the following process:

[0070] The first liquid pipe 888 is connected to the first port on the first auxiliary plate 21 and the second port on the third auxiliary cooling plate 23, and the second liquid pipe 889 is connected to the first port on the second auxiliary plate 22 and the second port on the fourth auxiliary plate 24. The first liquid pipe 888 and the second liquid pipe 889 are connected to an external water pump for discharging liquid into the auxiliary cooling device. By starting the water pump, the liquid enters the first cylindrical groove 213 through the first liquid pipe 888. The liquid will drive the first rotating blade 217 to rotate, and the first rotating blade 217 will drive the first internal threaded sleeve 216 to rotate. Under the cooperation of the first internal threaded sleeve 216 and the first threaded rod 215, the first internal threaded sleeve 216 rotates. The threaded sleeve 216 will move in the direction away from the first port 214, and the first internally threaded sleeve 216 will move with the first magnet 219, and the first magnet 219 will attract the second magnet 221 to move in the direction away from the first port 214. At the same time, the liquid will pass through the first hose 240 to reach the first inlet pipe 222, and the liquid flow will drive the second rotating blade 700 to rotate, and then flow out from the first liquid outlet pipe 224. The second rotating blade 700 will rotate with the first rotating shaft 225, and the first rotating shaft 225 will rotate with the first steel rod 302. When the first rotating shaft 225 rotates, the first steel rod 302 will collide with the inner wall of the first cavity 211 on one side close to the base 20. Then, under the action of the first return spring 304, the first steel rod 302 can be prevented from getting stuck when contacting the inner wall of the first cavity 211 close to the base 20, so that the first steel rod 302 can continuously knock on the inner wall of the first cavity 211 close to the base 20 under the rotation of the first rotating shaft 225, and because the first magnet 219 attracts the second magnet 221 to move in the direction away from the first opening 214, it will also move with the first steel rod 302, so that it can move from one side of the inner wall (the side close to the first opening) to the other side (the side away from the first opening), so that the formed workpiece can be better shaken by knocking. When the first rotating shaft 225 rotates with the rotating plate 320, the rotating plate 320 rotates and pushes the round-headed rod 332 to move into the straight groove 331. The round-headed rod 332 moves with the second push rod 337. The second push rod 337 pushes the first push rod 334 to rotate. The first push rod 334 knocks the base 20 with the knocking steel ball 336, thereby vibrating the contact point between the mold and the formed workpiece at the bottom, and the knocking vibration separates the contact point. When the rotating plate 320 leaves the round-headed rod 332, the round-headed rod 332 is reset under the action of the torsion spring. The working principle of the second auxiliary plate is the same as that of the first auxiliary plate.

[0071] At the same time, the liquid will also enter the second port on the third auxiliary cooling plate 23, then pass through the second cylindrical groove 233, and then pass through the second hose 250, the second inlet pipe 242, the second liquid outlet 243, and then flow out of the second liquid outlet pipe 244 into the second cavity 231. During the flow of liquid, the third auxiliary cooling plate 23 and the fourth rotating blade 701 will be driven to rotate. The fourth rotating blade 701 will drive the third magnet 239 to move away from the second port 234 under the cooperation of the second internal threaded sleeve 236 and the second threaded rod 235, and then the fourth magnet 241 will be attracted by the magnetic force of the third magnet 239 to move together in the direction away from the second port 234. At the same time, the fourth rotating blade 701 will drive the second rotating shaft 245 to rotate, and the second rotating shaft 245 will drive the second steel rod 402 to knock on the inner wall of the first cavity 211 close to the base 20, so that it can achieve knocking while moving, and the mold and the formed workpiece are separated by knocking and vibration. The working principles of the fourth auxiliary plate and the third auxiliary cooling plate are the same.

[0072] When the cooling liquid within the first and third auxiliary cooling plates needs to be pumped out, the first and second liquid pipes 888 and 889 are connected to external pumps for pumping the liquid. At this point, due to the change in liquid flow direction, the impact of the liquid will cause the first rotating blade to rotate in the opposite direction while moving toward the first port to reset. During this reset, the steel rod and steel ball will continue to strike. (The same process occurs when pumping out liquid from the second and fourth auxiliary plates.)

[0073] Therefore, after the formed workpiece is cooled, the cooling liquid can be extracted before the workpiece is demolded, and then the cooling liquid used to cool the next formed workpiece can be poured in. During the process of changing the cooling liquid, the formed workpiece and the mold can be knocked and vibrated multiple times to separate the two and assist in demolding. In this way, without adding additional steps, assisted demolding can be performed only by changing the cooling liquid, which facilitates manual demolding in the future, thereby improving work efficiency.

[0074] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
