[0040] One end of the fixed mounting bracket 205 is symmetrically inserted with mating connecting strips 206, and the bottom ends of the two mating connecting strips 206 are welded with forming fixed platforms 207.

[0041] Several pressing electric push rods 208 are symmetrically and equidistantly installed on the inner side of the fixed positioning frame 205. Each pressing electric push rod 208 has a pressing anti-slip strip 209 installed at one end. The longitudinal section of the insertion connecting strip 206 is T-shaped. One end of the pressing anti-slip strip 209 is attached to the side end of the insertion connecting strip 206. The top of the forming fixed table 207 is attached to the bottom of the fixed positioning frame 205, so as to realize the rapid assembly of the forming fixed table 207 and press and fix its edges to achieve accurate alignment.

[0042] A magnetic positioning plate 210 is installed on the top of the fixed card frame 205 and the bottom of the lifting operation plate 202. A fixed pull ring 211 is symmetrically welded to the top of the forming fixed table 207.

[0043] To ensure stable operation of the equipment, the input ends of the lifting electric slide rail 201, the lifting electric push rod 203, the pressing electric push rod 208, and the magnetic positioning plate 210 are all electrically connected to the output end of an external power supply.

[0044] A mating component 3 is provided on the side of the fixed processing box 1;

[0045] The supporting component 3 includes a closed light-shielding cover 301, an internal thread limiting block 302, a thread support block 303, a cooling processor 304, a storage fixing box 305, an exchange processing pipe 306, a guide fan 307, and an isolation mesh plate 308;

[0046] Several closed light-shielding covers 301 are installed at equal intervals on the side of the fixed treatment box 1. Several internal thread limiting blocks 302 are welded at equal intervals on the bottom of the fixed treatment box 1. Threaded support blocks 303 are rotatably connected to the inner side of the internal thread limiting blocks 302. The longitudinal section of the threaded support blocks 303 is T-shaped to achieve alignment and load-bearing limitation, and ensure the stability of the overall support.

[0047] A cooling processor 304 is embedded in one end of the inner side of the fixed processing box 1. A storage fixed box 305 is snapped onto the top of the fixed processing box 1. The length and width of the storage fixed box 305 are equal to the length and width of the fixed processing box 1, respectively. The bottom end of the exchange processing tube 306 is placed inside the fixed processing box 1 to achieve stable exchange processing and ensure the stability of internal air purification.

[0050] The working principle and usage process of this utility model are as follows: During 3D printing, the fixed processing box 1 is opened by closing the light-shielding cover 301, and the resin is placed in the resin storage position inside the fixed processing box 1. The operator holds the fixed pull ring 211 and inserts the insertion connecting strip 206 at the top of the molding fixed table 207 into the side end of the fixed card frame 205. After insertion, the pressing electric push rod 208 drives the pressing anti-slip strip 209 to move along the fixed card frame 205 and adhere to the side end of the insertion connecting strip 206. The side-mounted anti-slip strip 209 steadily presses the interlocking connecting strip 206 to achieve a fixed connection to the forming fixed platform 207. The lifting electric push rod 203 drives the universal joint 204 to move up and down, adjusting the position of each universal joint 204, thereby adjusting the angle of the fixed mounting bracket 205 and the forming fixed platform 207 to ensure the levelness of the forming fixed platform 207. After fixing, the two magnetic positioning plates 210 are magnetically combined to achieve the overall positioning combination, ensuring the stability of the positioning connection and positioning support.

[0051] After installation, close the light-shielding cover 301 to isolate the fixed processing box 1. The lifting operation plate 202 moves along the fixed processing box 1 via the lifting electric slide rail 201, bringing the molding fixed table 207 into contact with the resin. At this time, ultraviolet light scanning curing is used to achieve continuous curing printing. During continuous curing printing, the internal temperature will rise due to photocuring. At this time, the cooling processor 304 will cool the internal temperature. The air in the fixed processing box 1 is drawn out by the guide fan 307 and the exchange processing pipe 306. The air enters the storage fixed box 305 through the exchange processing pipe 306. The activated carbon inside dries and purifies the air to prevent odors from appearing during continuous curing and affecting the working environment. At the same time, the airflow is circulated to improve the cooling speed and uniformity and ensure a constant internal temperature. The support level of the fixed processing box 1 is adjusted by the internal thread limiting block 302 and the thread support block 303 to ensure the stability of the support.
