  • Injection mold and manufacturing method
    Patent number: 11433586
    Abstract: At a temperature at the time of molding, an end surface of an ejector pin in a sliding direction is as high as or higher than an upper surface of an upper surface portion of a mold body, the upper surface being adjacent to a cavity on the ejector pin side.
    Type: Grant

  • MOLDING DEVICE
    Publication number: 20210146584
    Abstract: A molding device includes an insert mold and a base mold. The insert mold is attached to the base mold in a replaceable manner. The base mold includes a frame and a pipe. Inside the frame, the insert mold is inserted. Inside the pipe, a fluid for temperature adjustment flows. Between the insert mold and the base mold, an elastically deformable heat transfer member is arranged. The heat transfer member is in contact with both the insert mold and the base mold at least during molding.

  • Lens Unit
    Publication number: 20150077839
    Abstract: The purpose of the present invention is to provide a lens unit which can create an effective light shield despite the simple process by which the lens unit is produced. A non-transmissive filler (BD) is filled and solidified in the gap between the outer periphery of a light shielding member (SH1) and the outer peripheries of a first lens (L1) and a second lens (L2).

  • Lens Unit Manufacturing Method, Lens Array, and Lens Unit
    Publication number: 20140055860
    Abstract: To provide a lens unit producing method capable for positioning a lens array with high precision over a long period of time, a lens array, and a lens unit. When the first flat surfaces LA1f come in contact with the respective tapered surfaces HLD1, the glass lens array LA1 cannot rotate more than that for the holder HLD. Meanwhile, since the tapered surfaces HLD1 are regulated by the respective opposite first flat surface LA1f, the glass lens array LA1 cannot move more than that relatively to the holder HLD. That is, by holding the glass lens array LA1 with the holder HLD, the glass lens array LA1 can be positioned with high precision for the holder HLD.
