<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 equipped with the features to enable temperature rise heat treatment of a forming body of a resin sheet, a cooling means is disposed on the periphery of a forming mold, and after the separation from the forming mold of a forming means, the cooling means is made to be progressed to the upper part of the forming mold, or composed to progress the forming mold to the lower part of the cooling means to cool the forming body. In addition, the forming device includes, as the cooling means, an ejection nozzle of cooling gas and a passage that rectifies the ejected gas and exhausts it to the side face direction. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
