    摘要： An annular insert (4) is arranged in the optical component molding cavity of a mold to surround an outer periphery of raw material resin in a direction in which the resin is distributed in the cavity to limit the distribution of the raw material resin and define an outer profile of a lens (L). With this arrangement, it is only necessary to provide raw material resin only by a quantity equal to the volume of the region surrounded by the molding surfaces of upper and lower mold inserts (14, 24) and the inner peripheral edge of the annular insert (4) of the mold, so that the required volume of the raw material resin can be reduced. Since the pressure is preserved at the outer periphery of the distributed resin by the presence of the annular insert (4), the residual strain of the resin is minimized to prevent generation of sink mark, thereby providing excellent optical characteristics on the lens (L).

    摘要翻译： 在模具的光学部件模制腔​​中设置环形插入件（4），以沿着树脂在空腔中分布的方向包围原料树脂的外周，以限制原料树脂的分布，并限定 透镜（L）的外轮廓。 通过这种布置，只需要提供等于由上模和下模插入件（14,24）和环形插入件的内周边缘（14,24）的模制表面包围的区域的体积的量的原料树脂 4），从而可以减少所需体积的原料树脂。 由于通过存在环形插入件（4）在分布式树脂的外周保持压力，所以树脂的残余应变被最小化以防止产生凹痕，从而在透镜（L）上提供优异的光学特性， 。

    摘要： A gate top member 23 is placed to a gate 22 opened toward the circumferential edge of a molding spectacle-lens cavity 13 formed between inserts 11 and 12. The plural gate top members 23 each having a different height are previously prepared, and attached with a bolt to be exchanged. In pilot production, it is checked for each of various lenses which opening configuration of the gate 22 can form a spectacle lens with defined great-precision by exchanging the gate top member 23 in order to obtain each gate opening configuration changed by exchanging the gate top member 23.
