[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 Figure 1 illustrates an embodiment of this utility model: a dual-material liquid silicone processing device, comprising an installation platform 1 and a mixing shell 2. The mixing shell 2 is fixedly connected to the left side of the installation platform 1, and a lower mold 5 is fixedly connected to the center of the upper part of the installation platform 1 by bolts. A telescopic rod 9 is fixedly connected to the right side of the installation platform 1, and a glue column 10 is rotatably connected to the output end of the telescopic rod 9. The lower surface of the glue column 10 contacts the lower mold 5. When the telescopic rod 9 shortens, the lower mold 5 to be produced is installed on the installation platform 1. Then, the mixed liquid silicone in the mixing shell 2 is transported to the lower mold 5. Through the cooperation between the molds, the liquid silicone is pressed into shape. After completion, the operator removes the formed silicone mold, the telescopic rod 9 extends, and drives the glue column to move linearly towards the lower mold 5. During the contact with the lower mold 5, the glue column 10 rolls, cleaning the residual liquid silicone on the surface of the lower mold 5. Then, the telescopic rod 9 shortens again, allowing the operator to clean the glue column 10.

[0023] Please see Figures 1-4In this embodiment, a pressure pump 3 is connected to the pipe above the mixing shell 2. One end of a conveying pipe 4 is connected to the pipe above the pressure pump 3, and the other end of the conveying pipe 4 is connected to the upper mold 6. A motor 11 is fastened to the top of the mixing shell 2. A stirring rod 12 is fixed below the output end of the motor 11. Two feed pipes 14 are connected to the pipe above the mixing shell 2. A resistance wire 13 is wound inside the mixing shell 2. Different materials are introduced into the mixing shell 2 through the two feed pipes 14 for fusion. At the same time, the motor 11 outputs torque to make the stirring rod 12 rotate, which fully mixes the different materials. The heating resistance wire 13 is also turned on to control the temperature of the mixing shell 2, so that the liquid silicone is always kept in a liquid state. After the stirring rod 12 has finished stirring, the pressure pump 2 generates high pressure, and the liquid silicone is transported to the space between the upper mold 6 and the lower mold 5 through the conveying pipe 4.

[0024] Please see Figures 1-4 As shown in the figure, in this embodiment, four support rods 7 are fastened to the four corners of the installation platform 1. An upper mold 6 is slidably connected to the four support rods 7. Two hydraulic rods 8 are fixedly connected to the upper platform 1. The two hydraulic rods 8 are symmetrically distributed on the installation platform 1. Two hydraulic rods 8 are fastened to the upper mold 6. A lower mold 5 is in contact with the lower part of the upper mold 6. The upper mold 6 is fixed to the four support rods 7 to limit the movement of the upper mold 6. The hydraulic rods 8 output hydraulic pressure to drive the upper mold 6 to move horizontally in the vertical direction. When the liquid silicone is being molded, the hydraulic rods 8 extend to make the upper mold 6 and the lower mold 5 tightly connected and sealed. When the molding is completed, the hydraulic rods 8 shorten to separate the upper mold 6 and the lower mold 5, and the operator takes out the product.

[0025] During operation, different materials are introduced into the mixing shell 2 through two feed pipes 14. The motor 11 outputs torque to rotate the stirring rod 12, which thoroughly mixes the different materials. The heating element 13 is also turned on to control the temperature of the mixing shell 2, keeping the liquid silicone in a liquid state. After the stirring rod 12 has finished stirring, the pressure pump 2 generates high pressure, which is then conveyed to the upper mold 6 and the lower mold 5 through the delivery pipe 4. At this time, the hydraulic rod 8 extends to tightly connect the upper mold 6 and the lower mold 5, maintaining a seal. After completion, the hydraulic rod 8 shortens to separate the upper mold 6 and the lower mold 5, allowing the operator to remove the product. The telescopic rod 9 extends, driving the silicone column to move linearly towards the lower mold 5. During contact with the lower mold 5, the silicone column 10 rolls, removing any residual liquid silicone from the surface of the lower mold 5. Then, the telescopic rod 9 shortens again to clean the surface of the lower mold 5 once more. Finally, the operator only needs to clean the silicone column 10.

[0026] Through the above steps, the two materials are thoroughly stirred using the stirring rod 12, which disrupts the laminar and turbulent flow of the fluid to accelerate molecular diffusion, improve mixing efficiency, and effectively prevent liquid silicone from adhering to the mixing shell 2. In conjunction with the resistance wire 13, the internal temperature of the mixing shell 2 is maintained to prevent the liquid silicone from solidifying and causing conveying difficulties. A telescopic rod 9 and a glue column 10 are also provided to clean the surface of the lower mold 5 after processing. The back-and-forth rolling of the glue column 10 removes any residual liquid silicone from the surface, eliminating the need for manual surface cleaning; only the glue column 10 needs to be cleaned. This addresses the problems of low efficiency, uneven mixing, reduced product quality, easy clogging of the mold microchannels, time-consuming cleaning and maintenance, extremely high labor costs, and reduced work efficiency associated with traditional dual-material liquid silicone processing devices.
