An injection molding machine comprises an upper frame, a lower frame, molding units, an injector, a plurality of perpendicular supporters, and a vacuum sealing unit. The lower frame is installed at the lower side of the upper frame in order to be able to elevated. The molding units include: an upper mold installed on the lower surface of the upper frame; and a lower mold, installed on the upper surface of the lower frame, which is linked with the upper mold or which changes the shape from the upper frame when the lower frame is elevated. The injector is installed for the upper part to the lower part of the upper frame to be inserted into the inside the upper frame and comprises: a cylinder which is supplied with raw materials; a plunger installed inside the plunger cylinder in order to be able to be elevated; an injection cylinder which elevates the plunger; and a nozzle unit which is installed in the lower end part of the plunger cylinder and is connected to the upper mold through the lower side of the upper frame, and which injects raw materials, compressed by descending of the plunger, into the molding units. The perpendicular supporters are arranged respectively on the outside of the molding units and support elevation of the lower frame. The vacuum sealing unit seals the upper and lower molds to be in a vacuum state during the upper and lower molds linkage. |
