<p><P>PROBLEM TO BE SOLVED: To provide an optical element molding device in which soaking is performed in such a manner that a temperature difference in plates therein is hard to occur, and an optical element with high precision is produced at a high yield by the soaking. <P>SOLUTION: Regarding the optical element molding device 1, a molding die in which an optical element molding stock is placed between the upper die and the lower die is successively carried to each stage of heating, press-molding and cooling provided at the inside of a chamber. The space between the lower side plates 3b to 5b in each stage 3 to 5 of heating, press-molding and cooling and the bottom plate of the chamber 2 is disposed with a cooling plate 10 via insulating boards 3c to 5c on the plate sides, and, in at least one of the plates, the heat transfer amount per time from the lower side plate to the cooling plate in the insulting board is made high at the high temperature part of the plate and is made low at the low temperature part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
