Special mold silicone rubber is used, which is sold in a double package, with component a being the rubber and component b being the catalyst. When preparing the product, the weight ratio of the ab component should be determined by considering the room temperature, strength and hardness of the mold. When the room temperature is 20-25 degrees, a:b=100:1.5. When the room temperature is low (but not lower than 10 degrees), increase component b by 0.1-0.3. If the room temperature is high, reduce the b component by 0.1-0.3. The specific method is to determine the total amount according to the volume of the mold, and then the a and b components are weighed accurately according to the proportion, placed in a vessel and stirred well, that is.
