[0046] Working principle: in use, after the slurry is poured into the mold, the mold is placed in the placing groove 404 on the mobile car 403. The first cylinder 4146 at the top end of the low-temperature box 1 is turned on, so that the upward closing door 4142 on the low-temperature box 1 is opened. The motor 4157 on the low-temperature box 1 is turned on, so that the screw rod 4158 drives the horizontal rod 4152 to move towards the mobile car 403, so that the second suction magnetic sheet 4154 contacts and is attracted to the first suction magnetic sheet 4151 on one side of the mobile car 403. Then the screw rod 4158 is reversely rotated to drive the horizontal rod 4152 to move back, so that the mobile car 403 and the mold are pulled into the low-temperature box 1. Then the closing door 4142 is closed, and the second cylinder 5036 is turned on to push the supporting plate 5035 upwards. The supporting plate 5035 is filled with constant-temperature water. After the supporting plate 5035 moves upwards, the constant-temperature water is pushed above the supporting plate 501, so that the mold is immersed in the constant-temperature water, and the slurry in the mold is subjected to low-temperature polymerization;

[0047] After low-temperature polymerization, the supporting plate 5035 moves back to separate the mold from the constant-temperature water. Then the closing door 4142 on the low-temperature box 1 moves upwards to open the low-temperature box 1. The horizontal rod 4152 on the low-temperature box 1 moves outward to push the mobile car 403 out to the middle of the top end of the connecting bridge 401. Then the electromagnet 413 is electrified to generate a repulsive force on the magnetic block 412 to push the clamping block 410 into the clamping piece 407 on the mobile car 403 to fix the mobile car 403. Then the horizontal rod 4152 in the low-temperature box 1 is separated, so that the second suction magnetic sheet 4154 is separated from the first suction magnetic sheet 4151 and returns to the inside of the low-temperature box 1.

[0048] When the mobile car 403 is located at the top end of the connecting bridge 401, the air inlet fan 5043 is turned on to bring external air into the heating cavity 5041, so that the heating resistance wire 5045 is electrified to heat the entering air. The air enters the space above the supporting plate 501 through the communication groove 502 to preheat the inside of the high-temperature box 2, so that the temperature in the high-temperature box 2 reaches the high-temperature polymerization temperature. At the same time, hot air sprays from the air outlet hole 5048 towards the mold through the connecting pipe 5046 to heat and dehumidify the mold, so that the water on the surface of the mold is removed, the high-temperature polymerization speed is improved, and the production efficiency is improved.

[0049] Subsequently, the closing door 4142 on the high-temperature box 2 is moved upward to open, the electromagnet 413 is powered off, the clamping block 410 is moved back to disengage the clamping piece 407 under the elastic force of the first spring 411, the motor 4157 on one side of the high-temperature box 2 is started, the transverse rod 4152 on the high-temperature box 2 is moved outward, the second suction magnetic sheet 4154 is attracted to the first suction magnetic sheet 4151 on the other side of the moving vehicle 403, and then the moving vehicle 403 is pulled into the high-temperature box 2; at this time, the mold is affected by the surrounding hot air, and the slurry is polymerized at high temperature;

[0050] After the high-temperature polymerization is completed, the closing door 4142 on the high-temperature box 2 is opened upward, the moving vehicle 403 is pushed out to the middle of the top end of the connecting bridge 401, and then the heating resistance wire 5045 is turned off; at this time, the air inlet fan 5043 still brings the external air into the high-temperature box 2 and sprays it out of the air outlet hole 5048 to the surface of the mold, so that the mold can be quickly cooled, the temperature can be quickly reduced to room temperature, and the processing efficiency can be improved.
