  • Patent number: 10131079
    Abstract: A side gate nozzle assembly for a hot runner apparatus comprises a disc shaped base body, a probe member, a sealing insulator, and a shape memory alloy washer. The probe member with a probe channel extends from the base body. A molten molding material is received through a melt channel of the nozzle body, and allowed to pass through the probe channel to be transferred to a cavity of a cavity member. The shape memory alloy washer is positioned between the base body and the sealing insulator. The shape memory alloy washer distorts linearly to push the sealing insulator and the probe member according to change in temperature due to transfer of the molten molding material from the melt channel to the cavity member via the probe channel. The distorted shape memory alloy washer prevents leakage of the molten molding material from the melt channel, and the probe channel.

    Abstract: A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

    Abstract: Cooling device for the drive for the adjustment of the needle (5) of a needle valve nozzle (3) in hot runner systems for injection molding machines, wherein the drive is mounted on the hot runner manifold (1) of the injection molding machine and wherein the drive housing (10), in which the drive is accommodated, is connected, on the side facing the hot runner manifold (1), with a heat sink (20) of the cooling device, which heat sink is formed as a separate part. According to the invention, the heat sink (20) of the cooling device is mounted on the side of the drive housing facing the hot runner manifold (1) without bearing the weight of the drive housing (10). The heat sink (20) is provided with through-holes, through which the supports (12), which are directly or indirectly connected to the hot runner manifold (1), can extend freely, to which supports the drive housing (10) is attached (FIG. 1).

  • Publication number: 20130243899
    Abstract: An edge-gated injection molding apparatus is disclosed for distributing a melt stream to a plurality of mold cavities aligned on opposing sides of an injection manifold assembly. The injection manifold assembly includes melt outlets aligned on opposing sides thereof with a nozzle seal in fluid communication with each melt outlet for transferring the melt stream to a corresponding mold cavity. A sliding relationship between each nozzle seal and its respective melt outlet while the nozzle seal is securely held relative to the mold gate permits misalignment between the nozzle seal and its respective melt outlet in the cold condition without causing stress on the nozzle seal. Under operating conditions, the sliding relationship permits subsequent alignment between the nozzle seal and its respective melt outlet. The nozzle seal has a two-piece gate seal with components thereof threadably coupled to each other such that relative rotation therebetween applies a sealing preload.
