    • An apparatus for producing a plastic molded article or product for use in an optical device is a mold assembly. The mold assembly includes a pair of molds having an inner mold surface forming a cavity with a preselected volume into which a molten molding material is injected via a gate or sprue to fill the cavity and thereby form a molded product having a sink surface and at least one mirror surface after the molten molding material has cooled. The inner mold surface includes at least one transfer surface portion against which the at least one mirror surface of the molded product is formed, and at least one non-transfer surface portion against which the sink surface portion of the molded product is formed. The mold assembly also includes at least one vent hole, at least one bore in communication with the vent hole so that a preselected air pressure is applied to the molten molding material in the cavity via the bore and the vent hole, and at least one exhaust hole adjacent to, but spaced from the vent hole. Thus, only a part of the molded article or product expected to sink is surely caused to sink while, e.g., a mirror surface is surely transferred to a desired part of the molded article or product.
    • 用于制造用于光学装置的塑料模塑制品或产品的装置是模具组件。 模具组件包括一对模具,其具有形成具有预选体积的腔的内模表面,通过浇口或浇口将熔融模制材料注入其中以填充空腔,从而形成具有凹面的至少模制产品 熔融成型材料冷却后的一个镜面。 内模表面包括形成有模制产品的至少一个镜面的至少一个转印表面部分和形成模制产品的沉没表面部分的至少一个非转印表面部分。 模具组件还包括至少一个通气孔,与通气孔连通的至少一个孔,使得经由孔和通气孔将预选的空气压力施加到空腔中的熔融成型材料,并且至少一个排气 孔与通气孔相邻但间隔开。 因此,只有一部分成型制品或预期会下沉的产品被确实地下沉,而例如将镜面确实转移到模制品或产品的所需部分。

    • A mold assembly for producing a molded object from resin. The assembly includes a cavity configured to be filled with resin to form at least one surface of the molded object into a predetermined shape with at least one transfer surface of the cavity. A molding insertion member is arranged to form another surface of the molded object, and a holding insertion piece is configured to hold the molding insertion member. The holding insertion piece includes a communication path that places a surface of the molding insertion member at a side opposite to the cavity in fluid communication with the exterior of the mold assembly and guides air from the exterior of the mold assembly toward the surface of the molding insertion member.
    • 一种用于从树脂制造模制物体的模具组件。 组件包括构造成填充有树脂的空腔,以将成型物体的至少一个表面形成为具有至少一个空腔传送表面的预定形状。 成型插入构件被配置成形成模制对象的另一表面,并且保持插入件构造成保持模制插入构件。 保持插入件包括将模制插入构件的表面放置在与模具组件的外部流体连通的空腔的一侧的连通路径,并将空气从模具组件的外部引导到模制件的表面 插入件。
