Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] See also Figure 1-Figure 4 The present application provides a liquid silicone optical lens molding mold including a mold assembly 100 and a driving assembly 200.

[0031] See also Figure 1 , 2 and 3, the mold assembly 100 includes a mold frame 110, a ceramic bottom plate 120, a ceramic side plate 130 and a ceramic protective plate 140, the ceramic bottom plate 120 is arranged at the bottom of the mold frame 110, the ceramic side plate 130 is arranged on the side plate of the mold frame 110, the mold frame 110 is opened with a flow channel 150, and the ceramic protective plate 140 is arranged on the outside of the flow channel 150.

[0032] It should be noted that the flow channel 150 is U-shaped, and the ceramic guard plate 140 extends into the flow channel 150. By setting up the U-shaped flow channel 150, the coolant enters at one end and exits at the other end, thereby absorbing and taking away the heat on the mold frame 110. At the same time, the ceramic guard plate 140 can conduct heat and dissipate the heat absorbed by the coolant to the outside, thereby improving the cooling effect on the mold frame 110.

[0033] In a specific implementation, the ceramic bottom plate 120, the ceramic side plate 130 and the ceramic protective plate 140 are all provided with heat dissipation grooves 160. By providing multiple heat dissipation grooves 160 on each ceramic plate, it is helpful to increase the contact area with the air, thereby facilitating heat dissipation.

[0034] See also Figure 1 , 2 and 4, the driving assembly 200 includes a bottom shell 210, a fixed column 220, a sliding member 230 and a vibrating member 250, the fixed column 220 is arranged in the bottom shell 210, the sliding member 230 is arranged on the surface of the fixed column 220, the bottom of the mold frame 110 is fixedly connected to the sliding member 230, and the vibrating member 250 is arranged in the bottom shell 210 and contacts the sliding member 230.

[0035] In a specific embodiment, the sliding member 230 includes a sliding frame 231 and a spring 232. The sliding frame 231 is slidably mounted on the surface of the fixed column 220. The spring 232 is arranged between the sliding frame 231 and the bottom shell 210. The sliding frame 231 and the spring 232 are arranged through the customs, and the sliding frame 231 can slide axially along the fixed column 220.

[0036] In a specific implementation, the spring 232 is sleeved on the surface of the fixed column 220. The spring 232 is sleeved on the surface of the fixed column 220 to limit the radial bending range of the spring 232 along the fixed column 220 so that it can be compressed and stretched normally.

[0037] In a specific implementation scheme, the vibration member 250 includes a motor 251 and a cam 252. The motor 251 is fixedly connected to the bottom of the bottom shell 210, and the cam 252 is installed at the output end of the motor 251. The motor 251 and the cam 252 are set, and the motor 251 is started. The motor 251 drives the cam 252 to rotate, and the cam 252 pushes the sliding frame 231, and the sliding frame 231 squeezes the spring 232, so that the sliding frame 231 vibrates along the fixed column 220, which is beneficial to remove bubbles in the internal liquid raw material.

[0038] A wear-resistant pad 2311 is provided on one side of the sliding frame 231 , and the cam 252 contacts the wear-resistant pad 2311 . The wear-resistant pad 2311 is provided to prevent the cam 252 from directly contacting the sliding frame 231 and causing wear.

The bottom shell 210 with the top and two opposite sides hollowed out is conducive to ventilation and heat dissipation, and the mounting plate and the holes are provided for installing the bottom shell 210 at a designated position.

[0040] The working principle of the liquid silicone optical lens molding mold is as follows: when in use, the liquid silicone optical lens raw material is injected into the mold frame 110, and the motor 251 is started at the same time to drive the cam 252 to rotate, and the cam 252 pushes the wear-resistant pad 2311 and the sliding frame 231, and the sliding frame 231 squeezes the spring 232 along the fixed column 220. The elastic effect of the spring 232 makes the sliding frame 231 vibrate along the fixed column 220, effectively removing the bubbles in the internal liquid raw material to ensure the product quality. After closing the upper mold, the ceramic bottom plate 120 and the ceramic side plate 130 are used to directly contact the internal liquid optical lens raw material, and the heat is transferred to the outer surface through the ceramic plate for dissipation, and the flow channel 150 is used to pass the coolant for heat exchange to further improve the heat dissipation efficiency, and the coolant can also be selectively not used.
