When the silicone gasket is produced, the gasket casting mechanism 4 will inject the silicone in a molten state into the interior of the mold platform 1, and then the heat dissipation auxiliary mechanism 5 will cool the silicone inside the mold platform 1 to make it quickly molded.

[0023] Specifically, the gasket casting mechanism 4 includes a mold cavity 401 opened at the upper end of the mold platform 1, a circular column core 402 is detachably installed inside the mold cavity 401, a casting circular groove 403 is opened on the inner side wall of the mold cavity 401, a silicone liquid tank 404 is detachably installed at the lower end of the installation straight plate 3, and an electric heating plate is arranged inside the side wall of the silicone liquid tank 404. When the electric heating plate is powered on, the liquid silicone inside the silicone liquid tank 404 is heated, thereby improving the fluidity of the liquid silicone. The movable mounting on the installation straight plate 3 A stirring assembly 405 is installed, and a driving motor 406 for driving the stirring assembly 405 is fixedly installed on the upper end of the straight plate 3. A material control valve tube 407 is provided at the lower end of the silicone liquid tank 404. A casting area is formed between the circular column core 402 and the inner wall of the mold cavity 401. The material control valve tube 407 is connected to the inside of the casting circular groove 403. Initially, the material control valve tube 407 is in a closed state. After the material control valve tube 407 is opened, the silicone in a molten state will enter the inside of the mold cavity 401 through the casting circular groove 403.

[0024] Specifically, the heat dissipation auxiliary mechanism 5 includes a fixed bracket 501 symmetrically installed on the left and right sides of the mold platform 1, and a heat dissipation fan 502 is fixedly installed on the fixed bracket 501. A rectangular cavity 503 is opened at the lower end of the mold platform 1, and the rectangular cavity 503 is located below the mold cavity 401. The inner wall of the rectangular cavity 503 is coated with heat dissipation silicone grease. After the liquid silicone enters the interior of the mold cavity 401 through the casting circular groove 403, the heat dissipation silicone grease will quickly discharge the heat inside the mold cavity 401. A cooling elbow 504 and a small water pump are fixedly installed inside the rectangular cavity 503. A cooling water tank 505 is arranged below the rectangular cavity 503. When the small water pump is powered on, the clean water inside the cooling water tank 505 will flow through the interior of the cooling elbow 504, thereby completing heat exchange.

[0025] More specifically, the stirring assembly 405 includes a stirring circular shaft movably mounted on the mounting straight plate 3, the upper end of the stirring circular shaft is transmission-connected to the driving motor 406, and a stirring blade is fixedly mounted on the outer side of the lower end of the stirring circular shaft. When the stirring circular shaft rotates under the action of the driving motor 406, a plurality of stirring blades will rotate synchronously, thereby stirring the silicone liquid in a molten state.

[0026] In this embodiment, during production and processing, the liquid silicone inside the silicone liquid tank 404 will enter the mold cavity 401 through the material control valve tube 407 and the casting circular groove 403. Next, the liquid silicone will be distributed between the circular column core 402 and the mold cavity 401, thereby completing the casting operation.

[0027] Next, the cooling fans 502 symmetrically arranged on the left and right sides of the mold platform 1 will simultaneously cool the liquid silicone inside the mold cavity 401. At the same time, the cooling silicone grease will transfer the heat inside the mold cavity 401 to the inside of the rectangular cavity 503, so that the liquid silicone inside the mold cavity 401 can be quickly cooled and formed.

[0028] Moreover, if Figure 4 As shown, the clean water inside the cooling elbow 504 is always in a circulating flow state. Therefore, after the heat enters the interior of the rectangular cavity 503, it will be absorbed by the cooling elbow 504, thereby ensuring that the interior of the rectangular cavity 503 is always in a low temperature environment, greatly improving the heat dissipation efficiency.

[0029] In addition, the stirring shaft inside the stirring component 405 will rotate rapidly under the action of the driving motor 406. When the stirring shaft rotates, multiple stirring blades will rotate synchronously. When the stirring blades rotate, the liquid silicone will be stirred at a uniform speed, which can not only eliminate bubbles, but also improve the uniformity of the liquid silicone, thereby ensuring that the gasket casting operation can proceed normally.

[0030] In this embodiment, a gasket casting mechanism 4 is provided, and the cooperation between the stirring component 405 and the driving motor 406 is utilized. During the silicone pouring process, the stirring component 405 will automatically stir the raw materials inside the silicone liquid tank 404 at a uniform speed, which can not only improve the uniformity of the silicone raw material and avoid crusting on the inner wall of the silicone liquid tank 404, but also effectively improve the fluidity of the silicone raw material to facilitate pouring. Moreover, in this embodiment, a heat dissipation auxiliary mechanism 5 is provided, and the cooperation between the heat dissipation fan 502 and the cooling elbow 504 is utilized. After the pouring is completed, the silicone gasket can be automatically cooled and dissipated to make it quickly take shape, which can effectively improve the efficiency of silicone gasket processing.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
