摘要： A compression molding device, which can obtain a high compression molding force without lowering the efficiency of article production, and whose molding means has a long service life, is provided. In the compression molding device, a one-side mold assembly moving means (58) includes a toggle link mechanism including two links (62) and (64), and a toggle link mechanism operating means (60), while an opposite-side mold assembly moving means (108) includes a hydraulic cylinder mechanism. When a one-side mold assembly (16) and an opposite-side mold assembly (18) are to be brought from an open state into a closed state, the one-side mold assembly (16) is first moved to a nearly closed state by the one-side mold assembly moving means (58), and then the opposite-side mold assembly (18) is moved from the nearly closed state to the closed state by the opposite-side mold assembly moving means (108).
