摘要： PROBLEM TO BE SOLVED: To provide a mold structure capable of easily molding an optical element even from a low viscous resin, etc. and capable of maintaining an operation of an ejector mechanism, and an injection molding apparatus and molding method incorporated with the structure.
SOLUTION: An ejector mechanism 82 is provided in a movable die 62 side opposite to a pre-determined position corresponding to a cavity CV interior side, and thus a molded article can be released from the movable die 62 by thrusting peripheral and central parts of a molded article MP. The ejector mechanism 82 pushes a resin seal 63b and a sealing material 63c provided in the pre-determined position, and thus the ejector mechanism 82 is sealed during a molding process. Therefore, immersion of a resin into projecting holes H1, H2, i.e., inserting holes of the ejector mechanism 82, can be prevented so that a reliable operation of the ejector mechanism 82 can be maintained in a mold release process.

摘要： PROBLEM TO BE SOLVED: To obtain an injection mold capable of still more enhancing the transfer properties of a fine shape, and an injection molding method.
SOLUTION: The injection mold has a movable mold 10, which is composed of a template 11, a core mold 12, a heat insulating material 13 and a surface processing layer 14, and a fixed mold 20 comprising a core mold 22 and constituted so as to fill a resin molding space 30 with a molten resin to mold an optical element. A heat insulating material 15 is interposed in the part being the upper edge part of the inner periphery of the template 11 and constituting a part of the resin molding space 30. Since the heat insulating material 13 is positioned on the back part of the surface processing layer 14, the transfer properties of the fine shape 14a are enhanced and, since the heat insulating material 15 is arranged adjacent to the fine shape 14a, the heat radiation of the resin is reduced and the transfer properties of the fine shape 14a is still more enhanced.

摘要翻译：要解决的问题：获得能够进一步提高精细转印性能的注射模具和注射成型方法。解决方案：注射模具具有由模板11，芯模12，绝热材料13和表面处理层14构成的可移动模具10和固定模具20，固定模具20包括芯模22和构成为用树脂成型空间30填充熔融树脂以模制光学元件。绝热材料15插入在模板11的内周的上边缘部分的部分中，并构成树脂模制空间30的一部分。由于绝热材料13位于表面处理的后部层14，精细形状14a的转印性能得到提高，并且由于绝热材料15邻近精细形状14a布置，所以树脂的散热降低，并且精细形状14a的转印性能仍然更高增强。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a resin molding mold, reducing temperature unevenness on the mold surface side and restraining the mold from being deformed due to mold clamping to achieve high-accuracy transfer.
SOLUTION: Since a template 73 uses material having a thermal conductivity higher than the base materials of a cavity part 71 and a temperature control part 72 as the base material, temperature unevenness formed by the temperature control part 72 can be made equal and transferred to the cavity part 71 so that temperature unevenness at the molding surface can be restrained. That is, the temperature of the molding surface can be kept more uniform without any increase in thickness as the whole to enable high-accuracy molding. Since the template 73 uses the material having rigidity higher than the base materials of the cavity part 71 and the temperature control part 72, the template 73 serves as a support to thereby reduce deformation in a cavity CV due to resin injection, holding pressure, mold clamping and the like. Thus, the shape accuracy of a molded article can be improved, and the occurrence of defective appearance such as burr can be prevented.

摘要翻译：要解决的问题：为了提供一种树脂模塑模具，减少模具表面侧的温度不均匀性并且限制模具由于夹持而变形以实现高精度的转印。解决方案：由于模板73使用具有高于空腔部分71和温度控制部分72的基材的导热率的材料作为基材，所以可以使由温度控制部分72形成的温度不均匀度相等，转移到空腔部71，从而能够抑制成型面的温度不均匀。也就是说，整体上可以使成形面的温度保持更均匀，而不会增加厚度，以实现高精度的成型。由于模板73使用具有高于空腔部71和温度控制部72的基材的刚性的材料，因此模板73用作支撑体，从而减少由于树脂注入，保持压力，模具的腔CV的变形夹紧等。因此，可以提高成型品的形状精度，并且可以防止毛刺等不良外观的发生。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain an injection mold enhanced in transfer properties, capable of effectively preventing the occurrence of warpage in a molded product and not damaging high cycling properties, and an injection molding method.
SOLUTION: The injection mold has a movable mold 10 and a fixed mold 20 and is adapted to the injection molding of an optical element comprising a resin material. Heat insulating materials 13 and 23 are interposed between core molds 12 and 22 and between surface processing layers 14 and 24 in both of the movable mold 10 and the fixed mold 20. Since the heat insulating materials 13 and 23 are arranged to both of the movable mold 10 and the fixed mold 20, the surface and back of the resin charged in a resin molding space 30 are thermally insulated without causing a temperature difference and the flowability of a resin is kept slightly longer than before temporarily. By this constitution, the transfer properties of a fine shape 14a are enhanced and the occurrence of warpage in the molded product is prevented.

摘要： PROBLEM TO BE SOLVED: To obtain a mold for injection molding and an injection molding method improving a transferability, at the same time, effectively preventing a defect such as a crack or the like from occurring on the molding, and also not disturbing achievement of high-cycle operation.
SOLUTION: The mold for injection molding to produce an optical element by injecting an amorphous polyolefinic resin into a space for resin molding in the mold and the injection molding method are provided. The surface temperature of the resin molding space when the amorphous polyolefinic resin is filled into the the resin molding space can be kept at a temperature higher than a glass transition temperature of the amorphous polyolefinic resin by arranging a heat insulating material around the resin molding space. The surface temperature of the resin filled in the resin molding space changes as shown in a curve b, the temperature at the time of completing filling of the resin is higher than the glass transition temperature as shown at a point A, a temperature difference B between the surface part of the resin (a skin layer) and a core part of the resin is small, therefore a residual stress at the dwelling process or a cooling process can be reduced.
