FORMING MOLD HAVING POROUS MEMBER INSTALLED WITH ELECTRIC HEATER, METHOD FOR RAPID HEATING/COOLING OF THE FORMING MOLD, AND APPARATUS FOR RAPID HEATING/COOLING OF THE FORMING MOLD

摘要

The present invention relates to a molding die having a porous member disposed together with an electrothermal heater, and a rapid heating / cooling method and apparatus for the molding die. According to one aspect of the invention there is provided a molding die of a new structure capable of rapid heating / cooling. The molding die according to the present invention includes at least a plurality of mold plates for forming a cavity for molding, an electric heat heater inserted into at least one mold plate among the plurality of mold plates, and at least a cavity surface of the mold plate. A mold plate including a porous member, a part of which is disposed behind the heat transfer heater, and the mold plate including the porous member includes a supply passage for supplying the heat transfer medium to the porous member and a discharge passage for discharging the heat transfer medium supplied to the porous member. Equipped. In the molding die according to the present invention, the mold plate can be completely cooled by heating the mold and passing the heat transfer medium in a state in which the porous member is filled with the heat transfer medium.
