发明名称 FOAM MOLDING METHOD
摘要 PURPOSE:To realize the easy cutting of a molded portion corresponding to a wide groove and give a cut mark about the same softness as that of a molded product main body by a method wherein foam molding material is poured for foam molding in the cavity of a foam molding tool, in which a wide groove is formed along the joining portion of a bottom force and a tip force, and, after that, the wide groove molding portion of an obtained molded product is cut off. CONSTITUTION:A wide groove 1D is formed along the joining portion of a bottom force 1A and a top force 1B. When a foam molding material 2A is poured for foam molding in the cavity 1C of a foam molding tool 1, the foam molding material 2A penetrates also in the wide groove 1D so as to form a wide groove molding portion 21. The wide groove molding portion 21 has a softness nearly equal to that of a foam molded product 2. The foam molded product 2 is removed from the forces by opening the bottom force 1A and the top force 1B and then trimmed by cutting off the wide groove molding portion 21 in order to obtain the final foam molded product 2. The cut mark 22 in the foam molded product 2 has a softness same as that of the remaining portion.
