Making convex tires Also known as mother molds, convex tires are made from concave tires. It generally includes a bottom mold and a mold circumference or a core and a mold circumference. Step 5: Making a working mold The convex tyre is turned over and used for grouting. 2 Mold material and classification (1) Traditional casting gypsum moldThe manufacturing process: the standard β-type semi-water gypsum powder is added with water to make a gypsum slurry, which is stirred And vacuum degassing, etc., injected into the master mold, after the gypsum hardens, it is demolded, and then properly trimmed, assembled, and dried at 50-60 ° C for 5-7 days. (2) Plaster for low-pressure fast drainage casting There are two types of molds with and without microporous pipe network. The gypsum mold with microporous pipe network is different from the previous one mainly: before pouring, it must be in the corresponding part of the master mold (2 away from the pouring working surface Centimeters), put into the shaped pipe network, the interface of these pipe networks can be connected to the vacuum and compressed air pipelines on the forming line, in order to drain water, mold release and mold dehydration during pouring. Materials are: microporous glass fiber hose, pipe diameter φ = 7.5mm; nylon wire for braided mesh φ = 9.5um: resin impregnating solution for mesh (based on resin, catalyst (Initiator, talc, etc.). These braided materials are braided into a pipe network in another specially made auxiliary master mold and cured. After being removed from the mold, it is used to make a master mold. The gypsum used is β- Gypsum or α-gypsum. The latter is 1 times higher in flexural strength than the former; the surface micro-hardness is 60% higher, and the tensile strength is about 2 times higher. However, the standard consistency water absorption is about 30% lower. -Gypsum is more suitable for making high-strength plaster models.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
