摘要：【中文】本发明提供的一种易于脱模的菲涅尔模具的制造方法，该方法中在与金属母模具有相同特征图案的金属子模的表面上沉积脱模层，接着在脱模层表面上通过电铸形成第一金属层，脱模后的第一金属层即为金属模具，金属模具的特征图案与金属母模的特征图案结构互补。由于脱模层为氧化物层，因此脱模层不导电且与金属离子结合力差，进而使得第一金属层不粘连金属子模，如此不仅易于脱模且可进行多次脱模，满足实际生产中需要大量复制电铸模具的需求。与现有技术相比不仅简单化了整体工序，提高了生产效率，而且降低了生产成本。 【EN】The invention provides a method for manufacturing a Fresnel mold easy to demold, which comprises the steps of depositing a demolding layer on the surface of a metal sub mold with the same characteristic pattern as a metal master mold, then forming a first metal layer on the surface of the demolding layer through electroforming, wherein the demolded first metal layer is the metal mold, and the characteristic pattern of the metal mold is complementary with the characteristic pattern structure of the metal master mold. The demolding layer is an oxide layer, so the demolding layer is not conductive and has poor binding force with metal ions, and the first metal layer is not adhered to the metal sub-mold, so that the demolding is easy and can be performed for multiple times, and the requirement that a large number of electroforming molds need to be copied in actual production is met. Compared with the prior art, the method not only simplifies the whole process, improves the production efficiency, but also reduces the production cost.
