Abstract
In supplying a predetermined amount of a molten resin D between an upper moldand a lower moldfor compression molding, after the upper moldis moved downward for a predetermined stroke length so that it approaches the lower moldin which the molten resin D has been supplied, a compression load is applied while moving the lower moldupward and supporting the upper moldsuch that clamping is conducted against the compression load which has been applied to the lower mold. As a result, when molding a molded article in a predetermined shape by compression molding, if molds are allowed to open with a sufficient stroke length for taking a molded article out, prolongation of molding cycle can be effectively prevented, whereby a molded product in a predetermined shape can be mass-produced.
