  • Patent number: 7510677
    Abstract: Injection molding method and apparatus for ejecting a molded plastic article from a mold. A lifting structure and/or step is provided with a lifting portion which is configured to contact substantially one half of an end of the molded plastic article along a line substantially perpendicular to the lifting direction. Since the molded plastic article is lifted by its end, the article does not have to be solidified at its interior, thus allowing earlier removal of the article from the mold, reducing cycle time. A tapered surface forms an acute angle with respect to the lifting portion to form a tight seal with the mold, preventing leakage. Preferably, the neck ring engages only an outer circumferential portion of the molded plastic article during a majority of a mold opening stroke.

  • Patent number: 6989124
    Abstract: Injection molding method and apparatus for ejecting a molded plastic article from a mold. A lifting structure and/or step is provided with a lifting portion which is configured to contact substantially one half of an end of the molded plastic article along a line substantially perpendicular to the lifting direction. Since the molded plastic article is lifted by its end, the article does not have to be solidified at its interior, thus allowing earlier removal of the article from the mold, reducing cycle time. A tapered surface forms an acute angle with respect to the lifting portion to form a tight seal with the mold, preventing leakage. Preferably, the neck ring engages only an outer circumferential portion of the molded plastic article during a majority of a mold opening stroke.

  • Patent number: 6869555
    Abstract: In a rear holder-attached connector (1), a relatively-thick protective rib (10) with a width (B) projects outwardly from opposite sides of a housing (2), and is disposed between upper and lower terminal receiving chambers (3). This width (B) is larger than a width of rear holders (20a, 20b), and this rib (10) protects the rear holders (20a, 20b) so that these rear holders, provisionally retained on the housing (2) within a metal-mold assembly, will not be discharged from the metal-mold assembly to drop, and will not be disengaged from the housing even upon contact with another housing. The provision of the protective rib (10) also serves to provide a good flow of a resin poured from the rear side of the housing (2) during the molding operation, and therefore thin partition walls, forming the terminal receiving chambers (3), can be positively molded, thereby enhancing the yield of the molded housings.
