INJECTION MOLD, MANUFACTURING METHOD FOR MOLDED BODY USING THIS MOLD AND PHOTOCONDUCTIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide an injection mold which rapidly controls the temperature of a cavity surface, shows a successful transferability of the cavity surface and can manufacture the molded body in a short molding cycle, a manufacturing method for the molded body to which the cavity surface is correctly transferred using the injection mold and a photoconductive sheet with significant brightness, less brightness unevenness and no warpage. SOLUTION: The injection mold comprises a movable half and a cavity side half each having a flow path into which a heating medium and a cooling medium are alternately flown. At least either of the movable half or the cavity side half has a slender vacancy formed at the rear of the flow path as viewed from the cavity. The method for manufacturing the molded body injection-molds a thermoplastic resin using the mold. The photoconductive sheet manufactured by this method is 4 mm or more in thickness and 355.6 mm or more in diagonal size. COPYRIGHT: (C)2004,JPO&NCIPI
