    摘要: An injection molding system is disclosed having a self-regulating valve for balancing melt flow. The self-regulating valve includes a control rod configured to balance the melt flow rate through a hot runner system. The self-regulating valve reacts to an injection or melt pressure within the hot runner system and a pre-set force provided by an external force device. The self-regulating valve is an open-loop system as it requires neither a measurement of pressure by a sensor nor feedback from a processor in order to regulate the melt flow. The self-regulating valve mechanically reacts to changes in melt pressure on control surfaces thereof by “bobbing” upwards/downwards to decrease/increase the melt flow accordingly. The self-regulating valve compensates for conditions that affect melt pressure, such as an increase/decrease in melt viscosity, changes in melt temperature, and/or mold cavity size without the use of a processing device.

    摘要: An injection molding apparatus is disclosed having a single level manifold that utilizes a melt splitter. The manifold defines an inlet and a plurality of outlets with at least one upstream melt channel and a plurality of downstream melt channels that are situated between the inlet and the plurality of outlets. The upstream melt channel branches into the plurality of downstream melt channels with the upstream melt channel and each of the downstream melt channels longitudinally extending in the same plane. The melt splitter is at least partially positioned within the upstream melt channel where the upstream melt channel intersects with the plurality of downstream melt channels. The melt splitter divides a melt flow received from the upstream melt channel into substantially equal volumes and then directs each of the substantially equal volumes into a respective one of the plurality of downstream melt channels.

    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: A valve gated hot runner nozzle with at least two transition members made of different materials located between a nozzle tip and a mold gate component to provide a thermal transition region. A first transition member in contact with the nozzle tip is less thermally conductive than a second transition member in contact with the mold gate component. The valve pin when in the closed position makes sealing contact with at least the second transition member such that cooling from the mold gate component is transferred to the valve pin to cool the melt in the mold gate area.

    摘要: A shut-off valve for preventing drool from an injection molding apparatus is provided in a melt channel of a sprue bushing. The shut-off valve includes a fixed member located in the melt channel and a reciprocating member coupled to the fixed member. The reciprocating member is biased toward an extended position in which an inlet of the sprue bushing is blocked thereby. The reciprocating member is movable from the extended position towards a retracted position in which the inlet of the sprue bushing is clear by the force of a melt stream entering the melt channel of the sprue bushing.
