<p><P>PROBLEM TO BE SOLVED: To provide a thermoforming device that can continuously carry out thermoforming to release mold rapidly, and efficiently by rapidly heating a forming body, or allocating the forming body in a cooling stroke while rapidly heating, and especially carrying out heat treatment at a high temperature more than a preheated sheet temperature before forming, in a process from forming to demolding of the thermal forming, and to provide a forming method. <P>SOLUTION: In a thermoforming device of a thermoplastic resin sheet that performs pressure forming by a heating plate of the resin sheet, the heating plate used is composed by (1) heating compressed gas or introducing heated compressed gas, and while sending out this gas to the compressed air space from a plurality of holes prepared at the one surface in the compressed air box, and (2) absorbing the sent out gas to the compressed air space from a plurality of holes prepared separately in the same surface of the heating plate and discharging it to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
