摘要： This invention teaches a hot runner injection molding apparatus for co-injecting at least two different materials into a mold cavity. A pin valve gated hot runner nozzle includes separate melt channels for each material and a melt chamber for accurately metering one of the materials. The melt chamber is in communication with an injection piston. The controlled movement of the valve pin and of the injection piston insures that the desired amount of a first and at least a second material is injected into the mold cavity. Depending of the composition and the processing window of the materials, the co-injection hot runner nozzle is in communication with either a single or multiple manifolds.

摘要： A nozzle is provided for an injection molding apparatus. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece. The nozzle body defines a nozzle body melt passage, which has an inlet that is adapted to be downstream from and in communication with a melt source. The heater is connected to said body for heating melt in said nozzle body melt passage. The tip defines a tip melt passage that is downstream from and in communication with said nozzle body melt passage. The tip melt passage has an outlet that is upstream from a gate in a mold component. The tip includes a tip sealing surface. The tip surrounding piece includes a first tip surrounding piece sealing surface. The first tip surrounding piece sealing surface and said tip sealing surface are separated by a gap.

摘要： An injection molding apparatus that includes a nozzle having a nozzle channel, a mold cavity in communication with the nozzle channel of the nozzle for receiving a melt stream of moldable material from the nozzle channel through a mold gate; and a valve pin that is axially movable through the nozzle channel of the nozzle between a first retracted position in which the valve pin closes the mold gate to block melt flow between the nozzle channel and the mold cavity, an extended position in which an end portion of the valve pin extends through the mold gate and into the mold cavity, and a third retracted position in which the end portion of the nozzle pin is withdrawn from the mold cavity into the nozzle and spaced apart from the mold gate thereby opening the mold gate. The end portion of the valve pin defines a melt flow path on an outer surface thereof that extends through the mold gate when the valve pin is in the extended position for transmitting the melt stream from the nozzle channel to the mold cavity when the valve pin is in the extended position.

摘要： A coinjection molding apparatus is disclosed that provides a skin material melt stream and a core material melt stream to a nozzle. The skin material melt stream forms an inner and outer layer of a molded article with the core material melt stream forming a core layer between the inner and outer skin material layers. A volume of the core material for forming the core layer may be manually adjusted between injection cycles to change a thickness of the core layer between a first molded article and a second molded article. Alternatively, a volume of the core material for forming the core layer may be automatically adjusted during an injection cycle to change a thickness of the core layer during formation of the molded article, such that the molded article will have a core layer with at least a first thickness and a second thickness.

摘要： A coinjection molding apparatus is disclosed that provides a skin material melt stream and a core material melt stream to a nozzle. A nozzle tip of the nozzle defines a central skin material melt passage for receiving the skin material melt stream, an annular core material melt passage for receiving the core material melt stream and an annular outer layer melt passage, which receives a portion of the skin material melt stream from the central skin material melt passage. The skin material melt stream from the central skin material melt passage forms an inner layer of a molded article, the core material melt stream from the core material melt passage forms a core layer of the molded article, and the skin material melt stream from the outer layer melt passage forms an outer layer of the molded article, wherein the three melt streams combine prior to entering a mold cavity.

摘要： One or more nozzles define separate nozzle channels. The nozzles are coupled to a manifold, so that each of the nozzle channels communicates with a different mold gate. A molding material distribution insert is coupled to the manifold and has a body defining a distribution channel and a plurality of drop channels equal in number to the nozzle channels. The distribution channel is an open distribution channel formed on an outer surface of the body and enclosed by the manifold. The drop channels intersect the distribution channel and exit the body at a different one of the nozzle channels. A valve pin bushing can extend into the drop channels. Valve pins can extend from actuators, through the valve pin bushing and the drop channels, and to the mold gates. A valve pin holder can be coupled to the actuator and coupled to heads of the valve pins.

摘要： An injection molding apparatus is disclosed having an actuated part that is movable in forward and rearward directions with a magnetic valve pin coupling attached thereto. A valve pin for opening and closing a mold gate is coupled to the magnetic valve pin coupling to be movable with the actuated part. When the actuated part is moved in an opening stroke direction and the valve pin experiences a stopping force, the magnetic valve pin coupling permits the valve pin to become decoupled from the actuated part to prevent continued movement of the valve pin with the actuated part.
