发明名称 MOLD AND METHOD FOR PRODUCING CRYSTALLINE THERMOPLASTIC RESIN MOLDED BODY
摘要 PROBLEM TO BE SOLVED: To provide a technique for producing a crystalline thermoplastic resin molded body having a smooth surface while sufficiently progressing the crystallization of the crystalline thermoplastic resin.SOLUTION: Provided is a mold having a cavity 50 for producing a crystalline thermoplastic resin molded body, comprising: a first mold 10; and a second mold 20 arranged so as to be confronted with the first mold 10, and comprising: a heat insulation layer 30 formed at least on a part of a metal face on the side of the cavity 50 of the first mold 10 and the second mold 20 and composed of porous ceramic; and a metal coating layer 40 formed on the surface of the heat insulation layer 30. The thickness of the heat insulation layer 30 is 200 μm or more, the thickness of the metal coating layer 40 is 50 to 100 μm, and almost the whole face of the surface in the metal coating layer 40 being a transfer face of transferring a smooth face to the crystalline thermoplastic resin molded body.
