At present, the custom design of the sole mold is becoming more and more complex under the market conditions, which makes the development and production of the traditional bottom mold feel more and more difficult, so the manufacturers only hope that the technology and equipment of precision casting to replace the traditional bottom mold production. The traditional bottom die production method is to use the whole copper plate or aluminum plate to directly process, relative to the high complexity of the bottom sample can be said to consume a lot of time and cost.
Ceramic shell shoe casting for many manufacturers of base casting industry, most can be divided into Xiao shoe casting method and gypsum shoe casting method, the former method is used in copper mold, and the latter method is used in aluminum mold, which is a more common practice.
The custom casting technology of sole mold was discussed
Shaw mold casting method is a kind of precision casting method, its application is very wide and the history is very long. And in the country earlier universal method is a method called dewaxing casting, this casting method is difficult to apply to large workpiece casting, so for dewaxing shoe mold foundry, as long as a large work will feel helpless, these two methods can be applied to non-cast metal, cast metal and super alloy materials for casting. The Shaw casting rule is applicable to some large castings or medium castings, such as mold castings such as shoe mold. The ceramic shell mold used in Xiao casting method is made of relatively refractory refractory sand and ethyl silicate 40 hydrolysate. After ignition and combustion, some small and even cracks will be generated on the surface, but these cracks will not affect the surface of the casting, but can effectively prevent the shrinkage and deformation of the size of the casting mold. The formation of these cracks is controlled by the distribution of refractory sand size, hydrolysates, hardeners and roasting techniques.
