    • PURPOSE:To prevent burr generation, by a method wherein a glass plate is placed and grasped in an injection mold after a seal and buffer member is mounted to the outer peripheral edge of said glass plate and a frame part is molded while a slit is formed along the inner peripheral edge of the frame part to remove the residual buffer member. CONSTITUTION:A seal and buffer member 7 formed into a shape having a U- shaped cross sectional area from rubber or a soft synthetic resin is mounted to the entire outer peripheral edge of a glass plate 2 so as to cover both surface of said glass plate 2 and the whole is placed in an injection mold. In this state, a molten hard synthetic resin is injected into the cavity constituted of a cavity mold 4, a core mold 5 and the outer peripheral edge of the glass plate 2 from a gate G to form a frame part 3. After the molten resin is solidified, the molds are opened to take out an operating window while a slit is formed to the buffer material along the inner peripheral edge 31 of the frame part 3 by a sharp knife and the residual buffer material 71 is removed to complete the operating window.
    • 目的:为了防止产生毛刺,通过在将密封缓冲部件安装到玻璃板的外周边缘之后将玻璃板放置并夹在注射模具中并在形成狭缝的情况下模制框架部分的方法 沿着框架部分的内周边缘移除残留的缓冲部件。 构成:将由橡胶或软质合成树脂构成的具有U形横截面积的形状的密封缓冲构件7安装在玻璃板2的整个外周边缘上,以覆盖玻璃板的两个表面 2并将整体放置在注射模具中。 在这种状态下,将熔融的硬质合成树脂从浇口G注入到由模腔4,芯模5和玻璃板2的外周缘构成的空腔中,以形成框架部分3.在熔融树脂 固化,模具打开以取出操作窗口,同时通过锋利的刀沿着框架部分3的内周缘31向缓冲材料形成狭缝,并且除去残留缓冲材料71以完成操作窗口 。

    • PURPOSE:To prevent sticking of a flash to a frame which obstructs a soldering process, etc., by providing each pair of the push plates which hold the frame and of the leaf springs which press the push plates at the upper and lower sides in a resin sealing mold. CONSTITUTION:A frame 1 is set in the groove 8 of a mold 2 so as to protrude its part into a molding room 7, one pair of push plates 11 are retreated by closing the mold 2 and one pair of corresponding leaf springs 12 are bent via one pair of retreating push plates 11. The frame is held by pressing one pair of corresponding push plates 11 with the elastic force of the leaf springs. Because one pair of push plates 11 correspond to several molding rooms 7 corresponding to an individual molding room 7, there is no clearance between a pair of push plates 11 and the frame 1. Then, a thermoset resin is put in from an opening part, poured into the molding room 7 via a passage 6 and the resin is pressed, heated and hardened.
    • 目的:为了防止将闪光灯粘附到阻碍焊接过程等的框架上,通过将保持框架的每对推板和在上侧和下侧将推板按压在一起的板簧 树脂密封模具。 构成:将框架1设置在模具2的凹槽8中,以将其部分突出到模制室7中,通过闭合模具2将一对推板11退回,并且一对相应的板簧12弯曲 通过一对后退推板11.框架通过用板簧的弹力按压一对相应的推板11来保持。 由于一对推板11对应于与各个成型室7对应的多个成型室7,所以在一对推板11和框架1之间不存在间隙。然后,从开口部放入热固性树脂, 通过通道6倒入成型室7中,树脂被压制,加热和硬化。
