PROBLEM TO BE SOLVED: To provide a cast polyamide resin molding tool, from which plate-like molded bodies can easily be unloaded, by a method wherein a polymerizable lectam liquid is prevented from leaking by ensuring the pinchingly fixation of tools and, further, a short time pinchingly fixation and separation of tool members constituting the tool is realized. SOLUTION: This cast polyamide resin molding tool is used for manufacturing a plurality of plate-like cast polyamide resin molded bodies by anionically polymerizing a polymerizable lactam liquid in a tool so as to arrange at least one or more temperature controllable movable middle hot platens 5 between two temperature controllable side hot platens 2 and 3, at least either one of which is made movable, and interpose spacers 6, in each of which a cavity 9 for casting the polymerizable lactam liquid is formed, among a pair of the side hot platens 2 and 3 and the movable middle hot platens 5 in order to install a clamping device 7, which can pinchingly fix the above mentioned respective members into an integral body and, at the same time, release them, on the one side hot platen. |
