    • In an injection molding die, there is defined a cavity for a frame or a cavity for the frame and an auxiliary cavity communicating with the cavity for the frame, and into the cavity for the frame or the auxiliary cavity, there is injected a melted resin from a runner through a gate, and a section of the gate has a width of 1 to 5 mm in the direction of a thickness of a plate glass and a width of 10 mm or more in the direction parallel with a side of the plate glass but smaller than a side length of the plate glass. When this die is practically used, a load that would be applied to a peripheral portion of the plate glass during injection molding is reduced, so that when the frame is integrally molded to the plate glass by injection molding, undesired breakage of the plate glass is suppressed.
    • 在注射成型模具中,限定了用于框架的框架或空腔和用于框架的腔体和与框架或辅助空腔的空腔连通的辅助空腔,注入熔融树脂 从浇道通过浇口,并且浇口的一部分在平板玻璃的厚度方向上具有1至5mm的宽度,并且在与平板玻璃的平行方向平行的方向上具有10mm或更大的宽度 但小于平板玻璃的边长。 当实际使用该模具时,减少了在注射成型期间施加到平板玻璃的周边部分的负荷,使得当框架通过注射成型一体地模制到平板玻璃时,平板玻璃的不期望的破坏是 被压制
