Abstract
PURPOSE:To contrive a reduction in product costs by shortening a molding cycle per piece of a molded product, by a method wherein a cavity unit is provided with a member performing clamping of a mold and a mechanism cooling the cavity unit solely by taking out the cavity unit. CONSTITUTION:Resin is injected into a cavity 30 constituted of molds 22, 23 of a cavity unit 21. After injection, the molds 22, 23 are clamped with a clamping member 34, gate seal is performed and when resin pressure is lowered, the cavity unit 21 is cooled solely by taking it out. As the cavity unit 21 is cooled solely by taking out the same, a molding cycle per piece of a resin molded product is shortened, also a loss in material is eliminated and a cost of a product is reduced.
