Abstract: A system and process for gas-assisted injection molding of plastic materials using gas holding pressure in the mold cavity. An infinitely controlled gas pressure valve is utilized to provide initial pressure in a sealed mold and the gas is vented to a prespecified pressure when plastic is injected into the mold cavity. Additional gas is injected into the plastic material from a gas pin assembly in order to force the plastic to completely fill the mold cavity and to provide a hollow cavity in the completed part. Once the injection molding process has been completed and the part has cooled and solidified, the mold is opened, and the completed plastic molded component or part is removed or ejected.

Abstract: An injection mold apparatus having two halves, a core portion and a cavity portion. One or more gas injection devices, such as porous metal devices, are located in either of the two portions of the mold. Once a charge of hot melted plastic is injected into the mold cavity, gas is injected through gas injection devices forcing the hot plastic against the opposite mold half and into any recesses and grooves. Gas seals are formed by the plastic to prevent gas in the mold cavity from reaching the exterior surface of the molded part during shrinkage of the plastic. The centers of mass of the plastic at rib intersections are optimally positioned to eliminate sink marks on the external finished surfaces of the molded parts.

Abstract: A gas assisted molding apparatus having gas introduced into the plastic charge as the charge is flowing into the mold cavity. The gas and plastic are simultaneously injected into the mold cavity and the gas can be introduced at the nozzle end or barrel of the injection molding machine. Optionally, the gas may be injected into a hot runner manifold or into the cavity itself simultaneously with the plastic. The apparatus includes a conventional gas injection mold, a source of inert gas, such as nitrogen, and an injection assembly. A common power source is used for both the injection of the plastic and the gas to assure simultaneous inflow of both the gas and the molten plastic at the same pressure.

Abstract: A gas injection pin mechanism for introducing pressurized gas into a mold cavity or melt stream. A stationary pin member is positioned directly in a bore or opening in a mold member without a sleeve member. The pin member is an elongated body member with a first end facing a mold cavity and a first gas passageway through the pin member connected to a second passageway that is traverse to the first gas passageway. The second gas passageway has an opening on an exterior lateral surface of the pin member and gas through the second gas passageway is introduced into the cavity in annular space between the pin member and the mold opening.

Abstract: A method and system for injection molding plastic articles which utilize a spill area whose volume varies within an article-defining mold cavity. In one embodiment, the volume increases during introduction of pressurized gas into the mold cavity. In another embodiment, the volume of the spill area varies during a plastic injection which fills the mold cavity. A core reciprocally mounted within the mold cavity partially defines the variable volume of the spill area. An air spring is utilized to control pressure on the core which counters the pressure of the plastic at an end face of on the core. In one embodiment, the end face of the core is non-flat to create an area where fluid plastic can exert pressure against the end face within the mold cavity during plastic injection and/or during introduction of pressurized gas.

Abstract: A method and system for injection molding plastic articles which utilize a spill cavity whose volume varies. In one embodiment, the volume varies during introduction of pressurized gas into a mold cavity flow coupled to the spill cavity. In another embodiment, the volume of the spill cavity varies during a plastic injection which fills the mold cavity. A piston reciprocally mounted within a cylinder defines the variable volume of the spill cavity. In one embodiment, a pneumatic control circuit controls the pressure on a lower surface of the piston to thereby control the position of the piston within the cylinder and therefore the volume of the spill cavity. In another embodiment, an air spring is utilized to control pressure on the piston which counters the pressure of the plastic on the piston. In one embodiment, a stop pin connected to the piston prevents the piston from leaving the cylinder when the mold is opened and solidified plastic in the spill cavity is to be ejected therefrom.
