A mold for a tile composed of a frame mold (2), a front mold (4) which is inserted into the frame mold from the front side thereof, and a rear mold (6) which is inserted into the frame mold from the back side thereof. The rear mold is composed of a plurality of plungers (5). A back pressure is applied to each plunger by the corresponding hydraulic cylinder mechanism (7, 8, 9, 10). The hydraulic cylinder mechanisms are connected to each other in such a manner that a fluid can pass through each mechanism. When the fluid pressure within each hydraulic cylinder mechanism is equal, the back pressure applied to each cylinder by the corresponding hydraulic cylinder mechanism is equal. <IMAGE> |
