PROBLEM TO BE SOLVED: To realize a molding die, which is easily assembled and disassembled and has no liquid leakage or the like, by a method wherein space parts, each portion thereof in contact with at least either one of a top surface plate and a bottom surface plate of which is opened, are formed in a spacer so as to closely join the opposing surface plates to the spacer by vacuumizing the space parts at the assembling of a molding die. SOLUTION: Space parts 4 are preferably arranged evenly over the whole periphery of a spacer 3. Thus, the whole periphery of the spacer 3 easily joins closely and evenly to surface plates 1 and 2. Further, through a slightly complicated structure results, preferably the space parts are communicated with one another. By vacuumizing the space parts 4 through connecting mechanisms 6 at the state of the temporary assembling of a molding die, the spacer 3 and the surface plates 1 and 2 can be joined closely. In addition, by introducing air through the connecting mechanisms 6 in the space parts, the joining between the spacer 3 and the surface plates 1 and 2 can easily be released. |
