The invention discloses a silica gel mould for preparing an imitation brick veneer material. As silica gel is high in price and raw material density and good in flowability, the silica gel mould is high in cost, heavy and easy to deform. The silica gel mould is prepared from the silica gel, a curing agent, silicone oil, color paste and polyphenyl granules according to a weight ratio of 100:(2-2.5):(1-4):(0.1-0.5):(0.5-3); the polyphenyl granules and the methyl silicone oil are added into the silica gel; as the polyphenyl granules are high in volume, low in density and light in weight, the prepared mould is low in price and light in weight; the methyl silicone oil is capable of reducing shrinkage of the silica gel, so that the prepared silica gel mould is hard to deform; the fatal shortcomings of high price, heaviness and high possibility of deformation of a conventional silica gel mould are overcome, and the advantages of high-temperature resistance, corrosion resistance, good tear resistance and high imitati
