Abstract

A mold device includes a frame that is a vertical wall having a first surface that is a vertical surface to which a holding mechanism is mounted and supported only by the first surface. A fixed mold base supporting a fixed mold, one surface thereof fixed to the first surface of the frame, and a mobile mold base supporting a mobile mold, the mobile mold base held by the holding mechanism so that the mobile mold base moves closer to and away from the fixed mold base. The holding mechanism includes a rail fixed to the first surface, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base. The mobile mold base is supported by the holding means without using a tie bar, and cantilevered on the first surface via the holding mechanism.
