PROBLEM TO BE SOLVED: To provide the molding method of a lamination type form, which is capable of affording the lamination type form inexpensively. SOLUTION: A die, consisting of a fixed mold 1, a movable mold 10, a pair of rotary molds 20, 20', which are provided rotatably in these molds, and retaining devices 30, 30', is employed. In primary molding, a hard material is injected and filled into cavities 4, 5, 23 constituted of the fixed mold 1, the movable mold 10, rotary molds 20, 20' and retaining devices 30, 30' to mold a primary form. In secondary molding, the movable mold 10 is opened under a condition that a part of the primary form is retained by the retaining devices 30, 30', then, the rotary molds 20, 20' are rotated to secure a cavity for secondary molding at the outside of the primary form and fill a soft material into the cavity. |
