PURPOSE: A vacuum mold is provided to reduce a generation of air bubble in a resin to be injected to the mold by mixing and injecting the resin in a vacuum state. CONSTITUTION: A vacuum mold comprises a chamber(10), a resin container(20) installed at an inside of the chamber, a resin(21), and a mold(30). The resin is mixed by a mixing screw(25) rotating in the inside of the resin barrel, and the resin is injected to the mold. A vacuum motor(11) is coupled at one side of the chamber, and the inside of the chamber becomes in a vacuum state by driving the vacuum motor. The resin barrel is installed into the chamber. The resin composed of a main material and a hardener is stored at the barrel, and mixed by the rotating screw. After mixing the resin, the resin is injected into the injecting port of the mold through an injecting pipe(31).
