摘要： A guide for a manifold plug of an injection molding apparatus comprises a guide body projecting from an inner wall of the manifold plug diametrically opposing an inlet of a manifold plug channel formed in the manifold plug. The inlet is aligned with a manifold channel of a manifold. The outlet of the manifold plug channel is aligned with a nozzle channel of a nozzle. The inlet is at an angle to the outlet. A guide surface is provided on the guide body for abutting a downstream portion of a valve pin extending into the manifold plug channel. The guide also facilitates flow of a melt stream of moldable material through the manifold plug channel.

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.
