摘要： A rotary actuated gate valve for directing melt from a channel in a manifold to a mold gate includes a valve stem extending through and rotatable within the manifold. The valve stem includes a groove in fluid communication with the channel, wherein the groove is adapted to be rotated into alignment with the mold gate and channel for allowing the melt to flow into the mold gate. The groove is also adapted to be rotated out of alignment with the mold gate and channel for blocking the melt from flowing into the mold gate. The gate valve also includes a mechanism for rotating the valve stem. Another embodiment includes a rotatable housing having a groove, which operates in a manner similar to the valve stem design.

摘要： Improved hot runner valve gate piston apparatus and method includes structure and steps whereby the air piston cylinder wall transmits less than all of the compressive force between the backplate and the manifold. Preferably, a backup pad is disposed in contact with the manifold and the backplate, for transmitting some of these compressive forces. Preferably, the backup pad also transmits heat from the backplate to the manifold, reducing the temperature of the cylinder wall. A flex member is preferably provided adjacent to or integral with the cylinder for absorbing some of the compressive forces between the backplate and the manifold, and in order to maintain the air seal between the piston cylinder in the air channel in the hot runner backplate.

摘要： The foregoing objects are attained by the inventive opposed gating injection method and apparatus of the instant invention for forming molded articles and for use with injection molders wherein a first mold half and a second mold half are adapted to cooperate and form at least one mold cavity. The invention includes a first injector nozzle positioned in a first mold half adjacent the cavity, for injecting a first molding resin into the cavity through a first orifice. A second injector nozzle is included which is positioned in the second mold half adjacent the cavity for injecting a second molding resin. The second resin may be different from the first resin or the same as the first resin. The second resin is injected through a second orifice unconnected with the first orifice. In accordance with the invention, the injector nozzles may be either simultaneously or sequentially activated for filling the mold cavity, and may be single material or co-injection type nozzles.

摘要： A novel valve gated injection molding system and valve gate reduces the formation of gate vestiges on parts molded therewith and enhances cooling of the tip of the valve stem during the cooling portion of an injection molding cycle. Channels are provided and extend from an area adjacent the contact area of the sealing portions of the stem tip and gate to the melt channel of the injection nozzle. These channels allow material, which would otherwise form a thin film layer in the contact area of the sealing portions of the stem tip and gate, to be expressed through the channels and back to the injection nozzle. As the formation of thin films is inhibited, an increased contact area, in addition to the contact area of the tip and gate sealing portions, can be provided to improve the transfer of heat energy from the tip to the gate when the gate is cooled.
