PURPOSE: A mold for fabricating a mid sole is provided to improve the productivity and to reduce the time required for manufacturing the mid sole by rapidly achieving the heat transfer of high/low temperature. CONSTITUTION: A column(12) fabricated by using corrosion-proof material is positioned in a box. The column(12) is provided for protecting a mold because the column(12) is not deformed even when it makes contact with steam or cooling water. The column(12) includes edge columns(12a) at which a flow variation of heat medium is created and a bottom column(12b) for varying a flow of heat medium flowing through a bottom of a mold(10). If a passage is formed in a mold made of aluminum without forming the columns, the mold is easily broken caused by the temperature variation and steam pressure.
