摘要： An injection molding apparatus having a valve pin plate coupling at least one valve pin to an actuator which, in operation, axially moves the valve pin plate between a closed position and an open position. The valve pin is coupled to the valve pin plate via a valve pin coupler. A biasing member is compressed against a support surface by the valve pin holder when the valve pin plate is in the closed position to create a supplementary coupling force coupling the valve pin to the valve pin holder.

摘要： The present invention refers to an injection molding nozzle for introducing a molten plastic to a mold cavity (15) of an injection molding tool via a slot gate (2, 2, 3). The injection molding nozzle includes a nozzle core (2, 3, 3) having an elongate edge (3B) and is received in an opening (1A, 1) in a housing (1, 1). A portion of the nozzle core (2, 3, 3) is spaced apart from the housing (1, 1) so as to define a nozzle flow channel that is in fluid communication between a source of the molten plastic and the slot gate (2, 2, 3), and at least a downstream portion of the nozzle flow channel that is between the housing (1, 1) and the nozzle core (2, 3, 3) surrounds the nozzle core (2, 3, 3) on all sides.

摘要： A co-injection hot runner nozzle comprises an inner melt flow channel and an annular outer melt flow channel that surrounds the inner melt flow channel. The inner and outer melt flow channels have a first common source. The nozzle further comprises an annular intermediate melt flow channel disposed between the inner and outer melt flow channels. The annular intermediate melt flow channel is at least partly defined by a plurality of spiral grooves, each spiral groove having a respective inlet and defining a helical flow path. Lands between adjacent spiral grooves increase in clearance in a downstream direction. An annular axial flow path is defined over the lands. A plurality of feeder channels having a second common source is configured to supply melt to the plurality of inlets of the spiral grooves. The relationship of feeder channels to spiral grooves may be one-to-one. The inlets may be longitudinal channels.

摘要： Methods and systems for co-injection molding multilayer articles having one or more molded apertures disposed between a gate region and a peripheral region of the article are disclosed. The articles include an interior layer disposed between an inner layer and an outer layer. An article has interior layer coverage over at least 98% of a perimeter of a cross-section of the article downstream of the one or more molded apertures. A method includes modifying fluid flowing past an aperture-forming region of a mold cavity to compensate for the drag of the aperture-forming region on the velocity of the fluid flowing proximal to the aperture-forming region.

摘要： The invention relates to an injection molding apparatus including a mold block, a nozzle, a gating system and a slug heater. The mold block defines a mold cavity having a mold cavity inlet. The nozzle has a nozzle inlet. The nozzle inlet is fluidically connectable downstream from a melt source. The nozzle inlet is upstream from the mold cavity inlet. A melt flow passage extends from the nozzle inlet to the mold cavity inlet. The gating system includes a valve pin and an actuator. The valve pin is movable between an open position wherein melt flow is permitted into the mold cavity, and a closed position wherein the valve pin blocks the melt flow passage to prevent melt flow into the mold cavity. The actuator is operatively connected to the valve pin to move the valve pin between the open and closed positions. At least one of the mold block and the valve pin includes a cooling system for selectively solidifying melt to form a slug immediately upstream from the valve pin when the valve pin is in the closed position. In use the slug blocks the melt flow passage to substantially prevent melt leakage past the slug when the valve pin is positioned away from the slug.

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.
