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 provide a method for manufacturing an imaging lens unit capable of suppressing a position deviation between a holder of an optical lens and a cover, and to provide a molding mold for the same.
SOLUTION: The molding mold device 20 has a fixed mold 24 and a movable mold 22. In the molding mold device 20, the holder 2 and the cover 4 are moved to a matching position by moving at least either one of the fixed mold 24 and the movable mold 22 to another one in a direction perpendicular to the opening/closing direction of the mold. Then the fixed mold 24 and the movable mold 22 can be clamped at the matching position.

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 provide a production process of resin molded article, which allows achieving uniform and gradual cooling by a simple structure and keeping the resin temperature from excessive fall until the resin gets to a cavity corresponding to the article part.
SOLUTION: Temperature of a molten resin is kept from excessive fall until the resin gets to a cavity CV, since the molten resin is filled in the cavity CV via a channel space FC formed by dies 41, 42 while holding the dies heated at a temperature, not lower than glass transition temperature minus 50°C and not higher than glass temperature plus 10°C, of the resin; wherein at least a part of the dies forming the channel space FC includes a low heat conductive material of 20 W/(m×K) or lower. Therefore, the resin is kept in a low melt viscosity when filled in the cavity CV, making it relatively easy to mold resin articles MP with a micro-pattern etc., especially a high precision lens LP.
