However, in practical applications, cold forming is difficult to effectively shape the middle plate of high-hardness mobile phone cases, and can easily lead to shaping deviations, middle plate breakage, and other problems, thus affecting the consistency and shaping effect of the product.

The connector 211 is connected to the upper shaping fixture 23, and a pressure sensor 212 is provided between the connector 211 and the upper shaping fixture 23.

[0068] By employing an electric cylinder 210 and a connector 211 in the first drive assembly 21, and setting a pressure sensor 212, precise drive and real-time pressure monitoring can be achieved, avoiding overpressure damage to the middle plate during the shaping process and improving the safety and controllability of the shaping process.

After the lifting component 22 rises to the preset height set by the sensing plate 260 and the slotted photoelectric switch 261, the control system receives the information from the slotted photoelectric switch 261 and then controls the first drive assembly 21 to stop driving the lifting component 22 to rise. This not only avoids the lifting component 22 from overtravel, but also has a fast response speed and stable operation.

[0075] The lifting stroke of the lifting component 22 is controlled by the limit component 26 to ensure that the upper shaping fixture 23 stops at the preset position, thereby avoiding overtravel that could damage the equipment or cause abnormal shaping, and improving the safety and reliability of the whole machine operation.

[0078] S2, the first heating component 230 of the upper shaping fixture 23 and the second heating component 240 of the lower shaping fixture 24 are activated to heat the pressure block 232 and the carrier 241 respectively, so that the temperature of the corresponding fixtures reaches the preset shaping temperature;

[0079] S3, the first drive component 21 drives the lifting component 22 to descend. Under the precise guidance of the guide component 13, the upper shaping fixture 23 moves smoothly down with the lifting component 22 until it closes with the lower shaping fixture 24. At this time, the pressure sensor 212 monitors the shaping pressure in real time to ensure that the pressure meets the process requirements.

[0080] S4, when the first heating component 230 and the second heating component 240 are working, the upper cooling channel 2304 and the lower cooling channel 2404 are supplied with cooling medium, and the temperature of the corresponding fixture is reduced by the upper cooling plate 2303 and the lower cooling plate 2403, so that the corresponding fixture maintains the preset heating temperature.

[0081] S5. After the heat shaping is completed, the first drive component 21 drives the lifting component 22 to rise, and the upper shaping fixture 23 moves up accordingly until the limit component 26 triggers the limit, the lifting component 22 stops moving and returns to the initial position.

[0082] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
