<p>PURPOSE:To distinctly develop uneven marks on the outer surface of a shoe bottom by forming projections on the undersurface of an upper mold, in proximity to the uneven mark parts formed on the space part surface of a secondary shaping mold. CONSTITUTION:A secondary shaping mold 1 has a space part 3, which is closed by the mold combination with an upper mold 2. The space part 3 is formed, copying the contour of a shoe bottom, and uneven mark parts 4 are formed on the side surface. Projections 5 are formed on the undersurface of the upper mold 2, and the shape of the projection 5 is formed thinner towards the top, and smooth taking-out from the mold is permitted. A primary molded bottom member 8 is formed by taking-out a bottom member, copying the contour of the shoe bottom. The primary molded bottom member 8 is formed larger by 30% or so than the thickness of the space part 3. After the primary molded bottom member 8 is inserted into the space part 3, the upper mold 2 is pressed and mold-assembled. The primary molded bottom member 8 is compression-molded by the upper mold 2 and the secondary shaping mold 1, and the primary molded bottom member 8 is strongly pressed towards the uneven mark parts 4 by the projections 5. After heating, cooling is carried out, and the taking-out from the mold is performed at normal temperature, and the shoe bottom on which the distinct uneven marks are developed is obtained.</p> |
