Abstract: A mold structure and the replacement method thereof. The mold structure has a lower molding plate, at least one lower die core, a plurality of lower supporters, a plurality of first positioning units, an upper molding plate, at least one upper die core, a plurality of upper supporters and a plurality of merging units. The upper die core and the lower die core are passed through by a plurality of fasteners, and fixed on the upper molding plate and the lower molding plate respectively. The upper supporters and the lower supporters are disposed around the upper die core and the lower die core respectively, and passed through by a plurality of fasteners to fix them on the upper molding plate and the lower molding plate respectively. A part of a first positioning unit protruding out of a lower supporter is inserted into a merging unit. The present invention provides an accurate way to fix die cores, improves procedures in conventional molding, further reduces process time and saves cost.
