摘要： According to the present invention, a nozzle cap is provided which has a housing end that threadedly engages the nozzle housing to secure the nozzle tip to the nozzle housing. The remainder of the cap substantially fills the space between the nozzle tip and the gate insert while maintaining a small clearance between the cap and both the nozzle tip and the gate insert in the region surrounding an outlet end of the nozzle. The clearance prevents direct conductive heat transfer from the outlet end of the nozzle tip to the gate insert yet is sufficiently small enough to substantially eliminate melt to flow past it.
摘要翻译：根据本发明，提供了一种喷嘴帽，其具有与喷嘴壳体螺纹接合以将喷嘴头固定到喷嘴壳体的壳体端。盖的其余部分基本上填充喷嘴尖端和浇口插入件之间的空间，同时在围绕喷嘴的出口端的区域中在盖与喷嘴末端和浇口插入件之间保持小的间隙。间隙防止从喷嘴尖端的出口端到浇口插入件的直接传导热传递足够小，足以基本上消除熔体流过其。

摘要： A system for generating a simulation of fluid flow in an injection molding process carried out by an injection molding machine having an injection unit for injecting the fluid into a manifold delivering the fluid to at least two injection ports leading to one or more cavities of one or more molds. The system comprises one or more programs containing a set of instructions that generate a calculated property, state, position or image of the fluid flowing into or through each cavity, the one or more programs using one or more variable inputs that are representative of one or more selected properties, characteristics or operating parameters of the machine or the fluid. The variable inputs include at least a first value indicative of a first fluid flow rate downstream of the injection unit leading to or through a first injection port and a second value indicative of a second fluid flow rate downstream of the injection unit leading to or through a second injection port.

摘要： A flow nozzle (10) that conveys plastic melt from an injection unit of a molding machine to a mold cavity (72) has an improved, removable seal design. The nozzle body (12) is designed to threadedly receive a nozzle tip (24) that includes an outlet (30) that communicates with the mold cavity. A thin-wall, cylindrical seal ring (40) includes a compression portion that is received between the nozzle body and nozzle tip and is compressed to create a seal between these two elements when the tip is assembled to the nozzle body. The seal ring further includes a sealing portion (50) that encircles the nozzle tip and has an outer diameter slightly larger than the outer diameter of the nozzle body.

摘要： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and a first gap seal surface. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The first gap seal surface is positioned on a structure that is connected at least indirectly to the nozzle body. The first gap seal surface is adapted to be separated by a gap with respect to a second gap seal surface on the mold component. The gap is sized to inhibit the flow of melt between the first gap seal surface and the second gap seal surface.

摘要： A system for pressure molding plastic material includes a source of hot flowable plastic material and a manifold for receiving hot flowable plastic material from the source and for transporting the hot flowable plastic material to a nozzle that is disposed within a nozzle cavity. A heater is provided to heat the nozzle and is positioned outside of, but close to, the nozzle cavity and includes at least one electrical supply wire. A shut-off seal is positioned within the nozzle cavity to seal the nozzle with respect to the wall defining the shut-off cavity. In addition, a secondary seal is most advantageously positioned between the shut-off seal and the heater for ensuring that any hot flowable plastic material that might leak through the shut-off seal does not come into contact with the electrical supply wire. This has been found to increase the reliability and operating life of conventional pressure molding systems.
