发明名称 MANUFACTURE AND MOLD OF DIFFERENT HARDNESS CUSHIONING BODY
摘要 PURPOSE:To obtain a different hardness cushioning body, the width of the different hardness part at the edge of which is small and the width of each slit formed at the surface of which is small, by a method wherein the pouring of foaming stock in each compartment between the inner wall surface of a mold and the partition wall is performed under the state that the partition wall is tilted to the center side of the mold so as to widen the space between the partition wall and the inner wall surface of the mold and, after the pouring, the partition wall is erected. CONSTITUTION:Each partition wall 40 is pushed down against its spring plasticity to the center side of a mold surface and fixed by attraction to each magnet 36 at the inner bottom face of a bottom force in order to widen the space between the inner wall surface 38 of the bottom force and the partition wall 40. After that, foaming stocks 44a, 44b and 44c, which are respectively made of flexible polyurethane foam stock and the like, are poured in compartments 42a, 42b and 42c. At this case, the foaming stocks 44a and 44b, which are to be poured in both side part compartments 42a and 42b, are set to develop foams, which are harder than the foam developed by the foaming stock to be poured in the center compartment 42c. Next, by separating the partition wall 40 from the magnet 36 by pulling, the partition wall is restored to its initial erect state by utilizing its spring elasticity. After that, a bottom force 26 is covered by a top force 24 so as to expand the respective foaming stocks 44a, 44b and 44c in the respective compartments 42a, 42b and 42c.
