Abstract: PURPOSE:To obtain a resin molding mold device capable of molding a resin molded form, for which an higher accuracy is requested, by a method wherein a shielding means, shielding the movement of resin between a runner unit and a cavity after filling the cavity with the resin through the runner unit, is provided. CONSTITUTION:In a condition before shielding a runner unit 4, resin in cavities 5, 6 is not cooled and not cured yet while receiving a mold maintaining pressure. When the runner unit 4 is shielded under this condition, the resin in the cavities 5, 6 is confined under a condition that the resin is not cooled and not cured yet while receiving a mold maintaining pressure. Accordingly, when the cooling of the resin in the cavities 5, 6 is advanced, the resin is cooled and cured from a condition that the same is receiving the molding maintaining pressure and, therefore, the resin is brought into a condition that the mold maintaining pressure can not be applied by the resin, previously cooled and cured in the runner unit 4, further, the cooling shrinkage of a molded form in the cavities 5, 6 becomes very small compared with a condition that the resin is cooled and cured while receiving evacuating effect due to the cooling shrinkage of the resin in the runner unit 4.
