[0037] Please refer to Figure 1 , Figure 3 andFigure 4 The outer surface of the injection tank 9 is fixedly connected with a supplement pipe 18. Through the supplement pipe 18, the user can conveniently supplement the material. Each injection assembly 10 comprises an injection cylinder 101, a piston 102, an injection pipe 103 and an electromagnetic valve 104. Each injection cylinder 101 is fixedly connected with the injection tank 9. Each piston 102 is fixedly connected with the top end of the injection pipe 103 close to the piston 102. Each piston 102 is slidingly inserted into the injection cylinder 101 close to the piston 102.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 The top end of the left two guide columns 2 and the top end of the right two guide columns 2 are fixedly connected with a power plate 14. The bottom of the two power plates 14 is installed with a hydraulic rod 15. The output end of the two hydraulic rods 15 is fixedly connected with the closing plate 3.

[0040] In the embodiment, the upper mold box 4 and the lower mold box 6 are quickly and stably closed and opened through the design of the matrix arrangement of the guide column 2 and the closing plate 3 and the power driving of the hydraulic rod 15. The time for disassembly and demolding is greatly shortened, and the production efficiency is significantly improved. The separate control design of the injection assembly 10 makes it possible to flexibly adjust the number of workpieces processed each time, thereby further optimizing the production process. The combination design of the heat dissipation block 5 and the heat dissipation fin 7 effectively improves the heat dissipation efficiency of the lower mold box 6, speeds up the solidification process of the material, and reduces the forming defects caused by heat accumulation. The arrangement of the ultrasonic generator 13 effectively eliminates the bubbles in the internal material, thereby further improving the forming effect and surface quality of the denture.

[0041] The working principle of the above embodiment is as follows: First, the operator adds the pre-prepared denture processing material into the injection tank 9 through the replenishment tube 18. The stirring shaft 11 and stirring blade 12 inside the injection tank 9 start to rotate under the drive of the motor, ensuring that the material is evenly mixed in the tank, avoiding material solidification, and ensuring the quality and consistency of the material during injection. The ultrasonic generator 13 inside the injection tank 9 starts to work, using the vibration of ultrasonic waves to eliminate air bubbles in the material, improving the molding effect and surface quality of the denture. Next, according to production needs, the operator selects the combination of the upper mold box 4 and the lower mold box 6 to be injected by controlling the opening and closing state of the solenoid valve 104. At this time, the hydraulic rod 15 starts to work under the drive of the power plate 14, pushing the closing plate 3 along... The guide post 2 slides smoothly down until the upper molded box 4 and the lower molded box 6 are tightly fitted together. The design of the guide post 2 not only improves the stability of the movement of the closing plate 3, but also ensures the accurate alignment of the upper molded box 4 and the lower molded box 6 during each injection. Then, the corresponding solenoid valve 104 opens, and the material enters the interior of the upper molded box 4 and the lower molded box 6 through the injection cylinder 101 and the injection pipe 103. The heat dissipation block 5 and the heat dissipation fins 7 begin to play their role, accelerating the solidification process of the material in the lower molded box 6 through natural heat dissipation or auxiliary heat dissipation by the fan 17. After the injection is completed, the hydraulic rod 15 drives in the reverse direction, driving the closing plate 3 to rise along the guide post 2, realizing the rapid separation of the upper molded box 4 and the lower molded box 6. The operator can easily remove the molded denture for subsequent processing and treatment.
