Abstract
A casting-thickness variable mold enabling the thickness of a casting to be quickly and easily changed in an on-line condition. The mold includes a stationary long-side frame, a movable long-side frame, and two sets of short-side frames provided at either end of a space between the long-side frames. Each set comprises a main short-side frame having a large width-determining dimension, and an auxiliary short-side frame having a small width-determining dimension. The main short-side frame is disposed on the side of the space contacting the stationary long-side frame, and is connected to a main short-side frame moving device comprising a short-side moving spindle and a spindle driver. The auxiliary short-side frame is disposed on the side of the space contacting the movable long-side frame, and is connected to an auxiliary short side frame moving device comprising a short-side moving rod and a rod-driving hydraulic cylinder.
