  • Patent number: 10183430
    Abstract: A method for injection molding of thermoplastic pole parts utilizes a mold to fix at least one vacuum interrupter and contact terminals during a molding process. At least one injection opening or gate for injection of thermoplastic material is formed into the mold. The mold is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and the injection openings or gates can be steered in such a way that they inject thermoplastic material simultaneously or with a defined time dependent injection pattern. This process alleviates the issue of a pressure gradient along the long axis of the molded pole part, shortens process times, and achieves a homogenous dissipation of material during the molding process.

    Abstract: A method for manufacturing a magnet-conductive device includes performing a punch process to a plate by a glue-injectable punch structure, wherein the glue-injectable punch structure includes a punch head and a control member. The punch head comprises an accommodating cavity, an injection hole and an inlet, and a supply channel is formed by the accommodating cavity, the injection hole and the inlet. The control member selectively obstructs the supply channel or permits the supply channel into conduction. By using the method for manufacturing the magnet-conductive device, the stack between plural plates is simplified, and the coupling strength between adjacent plates is enhanced. In addition, this invention considers the gel between adjacent plates to be insulating medium to lower the iron loss of the magnet-conductive plates.

  • Patent number: 8801991
    Abstract: A co-injected molded multi-layer article has inner and outer layers, an interior layer contained within the inner and outer layers and a surface portion to which a closure or other component may be heat-sealed. The article is molded by co-injecting the inner, outer and interior layer materials into a mold cavity of a mold. The interior layer material is caused to flow along a steam line offset from the zero velocity gradient of the combined material flow and biased toward a material flow for forming an outer wall of the multi-layer article. The resultant molded multi-layer article contains an interior layer located in a heat sealable region that avoids a breach or failure during a heat seal operation to seal an opening of the molded article.

  • Publication number: 20140183789
    Abstract: A molding system includes a plurality of injection heads each configured to inject molten polymer into a mold cavity. Each injection head has an outer body, a piston disposed within the outer body and defining a polymer chamber on a first side of the piston and a pressure chamber on an opposite second side of the piston. The piston moves from a retracted position to an extended position responsive to pressurization of the pressure chamber. Molten polymer is injected from the polymer chamber into the mold cavity as the piston moves from the retracted position to the extended position. Such systems may be used to mold relatively large articles of manufacture.

  • Patent number: 8758666
    Abstract: An apparatus for receiving a plurality of mold assemblies having a first mold portion and a second mold portion operably connected together for forming parts. The apparatus includes a mold holding member and a pair of spaced apart support members extending from the mold holding member to a manufacturing floor. A carriage device is cooperable with the mold holding member for engaging and moving the mold assembly. A lifting mechanism is used for moving the carriage device relative the mold holding member to move the mold assembly to be engaged with mold holding member. A turn table adjacent to the mold holding member holds the mold assemblies and is movable relative the mold holding member thereby replacing the mold assemblies. A controller is operably connected to the mold holding member and the turn table thereby moving the turn table relative the mold holding member to interchange the mold assemblies.

  • Patent number: 8715547
    Abstract: A method and apparatus of controlling commencement of an injection of a melt stream of moldable material from an auxiliary injection unit. A sensor is placed in an injection molding system to sense a condition related to an injection of a first melt stream of a first moldable material provided by a primary injection unit. Commencement of a second melt stream of a second moldable material from the auxiliary injection unit is initiated upon the sensed condition related to the injection of the first melt stream being detected at a preselected value. The sensed condition may be a pressure, velocity or temperature of the first melt stream as provided by a direct sensor, a force or strain on a hot runner component as provided by an indirect sensor or the occurrence of a function of the injection molding system as provided by a functional sensor.

  • Patent number: 8690563
    Abstract: A hot runner apparatus includes a mold plate defining a pocket; a plurality of sub-manifolds; and a bridge manifold positioned in the pocket and between the sub-manifolds. The bridge manifold and the sub-manifolds are oriented in a common plane. The bridge manifold receives a melt from a melt source. Each of the sub-manifolds is coupled to the bridge manifold to receive the melt from the bridge manifold via a junction between an opening of a network of melt channels within the bridge manifold and an opening of a network of melt channels within each of the sub-manifolds. The sub-manifolds are urged against the bridge manifold to form a seal therebetween, when the bridge manifold and the sub-manifolds thermally expand urging the sub-manifolds against contact regions of a pair of opposing walls of the pocket. The respective opposing walls define a hollow region separated from the respective contact regions by a wall portion.
