[0043] Preferably, each air hole 345 and the first through hole 333 are arranged in a circular truncated cone type with the upper part being narrow and the lower part being wide. Since each air hole 345 and the first through hole 333 are narrow at the top and wide at the bottom, if there are impurities on the surface of the phenolic molding plastic during the cooling process, the impurities can fall into the base 34 during the process in the cooling box 3. At this time, since the top of each air hole 345 and the first through hole 333 is the smallest in diameter, the situation that the impurities on the surface of the phenolic molding plastic fall off the workbench 1 is reduced.
