The manufacturing industry such as tire product must be changed to consult the taste of customers and is required to make the best product that it has improved more stability and driving performance at consumer's desire in a short time. So, many researchers have been tried to produce the mold product of good quality and to reduce the manufacturing process in mold industry. And, they are increasingly concentrated on process technique development of tire mold using aluminum (Al) alloy. Generally, there are two types of separating method in the tire mold manufacturing process. The first, and basic one, is a full-casting mold which is obtained the product of uniform quality and is easy the mass production. However, the product of width tire that tread pattern is complex is difficult.
The second type of separating method is sectional-casting mold, in which the product of width tire having a complex pattern is made without a defect because it is manufactured to 6 ~ 8 equal division. But, in this case, because rubber flush is apt to occur from division part, casting mold must have a high precision and need a long time in manufacturing process. Also, precision of casting mold can decrease by contraction during the solidification process in mold.
Therefore, this study presents numerical analysis applying a finite element method (FEM) on thermal deformation characteristics of aluminum alloy mold for automobile tire production. To analyze the thermal deformation characteristics on the inside of sectional-casting mold using Al alloy, it is investigated the temperature, thermal displacement and thermal stress of Al alloy tire mold using a FEM. The numerical results are presented to help to make the effective and the best tire mold. In addition, the introduced technique of numerical work needs to improve the precision of mold and particularly is very useful to analyze the material processing technology.
