摘要： A method and apparatus for making a plastic injection molded part with a smooth surface or skin and a hollow core wherein thermoplastic material is injected as a molten stream into the mold cavity through a sprue bushing fixed in the mold. Simultaneously, an unmeasured quantity of inert gas is introduced through an adapter into the molten stream at the sprue bushing substantially coaxially with the melt stream and at a pressure sufficient to penetrate the thermoplastic material to form a gas cavity in the molten material in the mold. For retrofitting an existing mold, an adapter can be added to the exisiting sprue bushing. During plastic injection and cooling in the mold the gas is maintained at a high pressure, preset, constant and adequate to maintain the plastic against the mold surface until it is self-supporting. The gas is exhausted from the mold, back through the sprue bushing and adapter, before the mold is opened. Adequate preset high pressure is maintained at the gas supply by a large cylinder having a positive displacement member therein that is controlled by a pressure sensor in the gas pressure line to the mold to maintain preset adequate gas pressure within the cavity.

摘要： A method for injecting a viscous fluid and a non-viscous fluid into a mold cavity of a mold body includes the step of regulating a flow of viscous fluid through a nozzle body discharge end and into a mold cavity with a valve element. The valve element is mounted for reciprocation in a nozzle body flow passage and includes a barrel having a first end, which selectively engages a portion of the nozzle body discharge end to prevent a flow of viscous fluid therepast, and a second end. A bore extends longitudinally through the barrel and a pin is positioned in the bore. A non-viscous fluid flow passage is defined between the pin and the barrel wherein the non-viscous fluid flow passage is annular in shape and has a substantially constant diameter at and adjacent the barrel first end. A viscous fluid flows through the nozzle body flow passage around the barrel and into the mold cavity. A non-viscous fluid flows through the non-viscous fluid flow passage around the pin and into the mold cavity.

摘要： A process for producing an injection molded product includes introducing a stream of plastic material into a mold space at a first pressure. A quantity of gas is stored in a storage chamber at a second pressure which is at least as high as the first pressure. The gas is introduced into the molten stream of plastic material immediately after the molten material has passed the position at which the gas is introduced thereby forming a gas cavity in the molten material. The gas exerts pressure on the surrounding plastic material to urge the material toward the surfaces of the mold space. As the feeding of the plastic material into the mold space continues, the injection of the gas is also continued. The supply of molten material is terminated when the surfaces of the mold space are completely covered by the molten material. A pressure is held within the gas cavity as the plastic material cools. Subsequently, the pressure is released to bring the mold space to ambient pressure. Then the mold is opened to remove the hollow shaped article. An apparatus for producing an injection molded product is also disclosed.

摘要： A bushing used in an injection molding machine and positioned between the nozzle and the sprue thereof includes an adaptor body having a longitudinal axis, a first end and a second end. A first bore extends in the adaptor body parallel to the longitudinal axis from the second end to the first end for accommodating a flow of relatively viscous fluid such as a molten thermoplastic. A bridge extends transversely across the first bore between opposing walls of the bore adjacent the adaptor body first end. Fluid flow is allowed through the first bore around the bridge. A second bore extends from a surface of the adaptor body to a surface of the bridge for accommodating a flow of a relatively non-viscous fluid such as gas. The second bore terminates on the bridge surface so as to be substantially coaxial with the first bore.
