  • Patent number: 9545742
    Abstract: A mold for forming tilt boss includes a slider part, a main part and a core pin. The slider part is formed with a tilt groove. The main part is formed with a tilt channel. When the slider part and the first main part are engaged, a tilt-boss forming cavity is formed. The tilt-boss forming cavity is communicated with the tilt channel and coaxial with the tilt channel. The core pin penetrates the tilt channel and one distal portion thereof is slidably engaged with the tilt groove, another distal portion thereof is protruded into the tilt-boss forming cavity. When the slider part is separated from the main part for allowing the core pin to be moved from a high point to a low point of the tilt groove, the core pin is downwardly moved along the tilt channel.

  • Patent number: 9205580
    Abstract: A coupling element, an injection molding object with the coupling element implanted therein are provided. The coupling element has two reversely extended fixing ribs. The injection mold has a first mold and a second mold. The first mold has a first molding cavity and two positioning blocks separated by the first molding cavity. The second mold has a second molding cavity. When the first mold and the second mold are shut together and their molding cavities combine to define a closed room, the positioning blocks hold the coupling element by clamping the fixing ribs so the coupling element is suspended in midair of the closed room.

  • Patent number: 9004908
    Abstract: An injection-molding device includes a male part, a female part, a vertically-moveable slider, a horizontally-moveable slider and an elastic element. The female part is detachably engaged with the male part, and an insertion groove is collectively formed by the male part and the female part. The vertically-moveable slider is detachably inserted in the insertion groove, and formed with a first inclined plane. The horizontally-moveable slider is detachably inserted in the insertion groove, formed with a second inclined plane being slidably engaged with the first inclined plane, and a closed cavity is collectively defined by the vertically-moveable slider, the horizontally-moveable slider, the female part and the male part. Two opposite ends of the elastic element are respectively abutted against the vertically-moveable slider and the horizontally-moveable slider.
