PROBLEM TO BE SOLVED: To provide a device for forming thermoplastic members where, in mold forming for thermoplastic members such as optical stocks, forming can be simultaneously performed to many members, and also, uniform heating and the increase of a cooling speed can be realized. SOLUTION: The device is composed of a first die 1 as a pressing member and a second die 2 provided with a plurality of molds 9, and in which the molds 9 are pressed, and thermoplastic members placed in the molds 9 are formed, and the molds 9 are arranged in the shape of a concentric circle at equal intervals in the second die 2. The second die 2 is provided with heat sources 6, 7 for uniformly heating the plurality of molds 9. The heat sources 6, 7 are provided at least on either the central part of the second die 2 or the outer circumference of the outside of the second die 2. The second die 2 is provided with cooling passages 20, 21 of uniformly cooling the molds 9. The cooling passages 20, 21 are provided in the shape of a concentric circle among the molds 9 or at the parts on the sides inner than the molds 9. COPYRIGHT: (C)2006,JPO&NCIPI |
