A molding device includes a lower die core assembly including a porous lower die core unit, an upper die core assembly including a porous upper die core, a heating assembly for heating the lower die core unit and the upper die core, and a control assembly operable to control temperature of an assembly of the lower die core unit and the upper die core to be direct proportional to a distance by which the upper die core is moved downwardly from a compression starting position where the upper die core comes into contact with the lower die core unit. The control assembly is further operable to control one of a heated gas and a cooled gas to be introduced into and discharged from the upper and lower mold core assemblies at different rates.

A negative mold for casting a component such as a blade of a wind turbine is described. The negative mold includes a support structure and a plurality of foam blocks, which are mounted to the support structure in such a manner, that a common surface contour of the plurality of foam blocks defines an outer surface of the component, which is to be casted. Each foam block of the plurality of foam blocks is taken from a predetermined number of different types of foam blocks, each type of foam block is defined by a predetermined foam block size and foam block shape. A method for producing such a negative mold is also described.

A slit forming part can be easily formed on a parting surface of a split mold and a change in a slit vent formed by the slit forming part can be suppressed. Parting surfaces including slit forming parts are formed on the split mold. Plating is applied to the parting surfaces of the split mold so as to coat the parting surfaces in which the slit forming part is formed, with a plating film. A plurality of split molds are combined together such that their parting surfaces opposed to each other, to mold a rubber article. The slit forming parts of the parting surfaces form a slit vent between the split molds.
