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 mold assembly is made up of a nozzle tip and a nozzle tip receiving housing. The nozzle tip has an outwardly projecting shoulder and a threaded base and the housing has a hollow stem with an internal recess and a threaded socket for receiving the base of the nozzle tip. The assembly further includes a locking member having both internal and external projections. The locking member fits over the nozzle tip with the external projection of the locking member locating within the internal recess of the housing stem and with the outwardly projecting shoulder of the nozzle tip trapped by the internal projection of the locking member to block unthreading of the nozzle tip from the housing.

摘要： A three piece nozzle assembly for injecting molten plastic in an injection molding machine carrying out a high pressure, high volume continuous molding process to mold thin walled parts. A nozzle housing has an internally threaded dual diameter bore in one end which receives in one bore portion an externally threaded shank of a nozzle. A sleeve is threaded into the other bore portion and is tightened adjacent to a flange on the nozzle shank to lock the nozzle to the housing and prevent the pressure of the injection molding from working the nozzle loose from the housing. A gap is formed between the sleeve and nozzle shank to reduce the thermal effects.

摘要： A mold bushing for injecting plastic material into a mold cavity. The bushing member has a one-piece body member with a central passageway for a shut-off gate pin member and a separate and distinct passageway for the molten plastic material. A tip member is positioned on the end of the body member and has a material discharge chamber. A gate or orifice opened and closed by the pin member is positioned either in the tip member or the mold. A wear bushing member is positioned in the discharge chamber or the end of the body member and acts to support the end of the pin member and prevent the flow of plastic material into the central passageway. The body member is heated by an annular cast heater member or the like. The wear bushing member can be indexed for proper positioning relative to the body member and the plastic flow passageway. The wear bushing member preferably has a body portion which partially fills the discharge chamber in the tip member. In an alternate embodiment, the body member has an extension which partially fills the discharge chamber and the wear bushing is a cylindrical member positioned at the discharge end of the central passageway.

摘要： A modular injection nozzle system for use with hot runner injection machines employs a thermal insulating element between the tip of the injection nozzle and a removable mold gate insert. This thermal insulating element limits the heat loss from the tip to the gate insert, assists in sealing the gate area and provides assistance in aligning the gate and the nozzle during assembly. The removable mold gate insert allows for eased servicing and assembling/dis-assembling of the injection nozzle system and has limited contact with the mold plate. In one embodiment, the removable gate insert is mounted to the nozzle via the insulating member, which is in the form of a sleeve with exterior threads which are complementary to interior threads on the gate insert. The sleeve can either be press-fit onto the nozzle or can have interior threads which are complementary to exterior threads on the nozzle. In either case, the sleeve can assist in the alignment of the components of the nozzle system. In another embodiment, the insulating element also includes an gap between the nozzle tip and the gate insert, the gap having a suitable insulating gas or vacuum therein to provide additional insulation. In another embodiment, the insulating element comprises a layer of insulating material on the nozzle tip and the gate insert can either be press fit with the layer or the layer can have exterior threads can into it to engage complementary threads on the gate insert. In another embodiment, the insulating element is molded in place on the nozzle tip.
摘要翻译：与热流道注射机一起使用的模块化注射喷嘴系统在注射喷嘴的尖端和可移除的模具浇口插入件之间采用绝热元件。这种绝热元件限制了从尖端到栅极插入件的热损失，有助于密封浇口区域，并在组装过程中提供对齐浇口和喷嘴的辅助。可移动的模具浇口插入件允许喷射喷嘴系统的易于维护和组装/拆卸，并且与模具板具有有限的接触。在一个实施例中，可拆卸的门插入件经由绝缘构件安装到喷嘴，该绝缘构件是具有外部螺纹的套筒形式，该外部螺纹与栅极插入件上的内螺纹互补。套筒可以压配合到喷嘴上，或者可以具有与喷嘴上的外螺纹互补的内螺纹。在任一情况下，套筒可以帮助喷嘴系统的部件的对准。在另一个实施例中，绝缘元件还包括喷嘴尖端和浇口插入件之间的间隙，间隙在其中具有合适的绝缘气体或真空以提供额外的绝缘。在另一个实施例中，绝缘元件包括在喷嘴尖端上的绝缘材料层，并且栅极插入件可以与该层压配合，或者该层可以具有外部螺纹可以插入其中以接合栅极插入件上的互补螺纹。在另一个实施例中，将绝缘元件模制在喷嘴尖端上的适当位置。

摘要： An injection molding nozzle is provided that includes a heater disposed about an insert seated in the nozzle body. The heater provides extra heat about the insert where heat loss to the mold can cause a reduction in melt temperature. The heater remains on from one injection cycle to the next injection cycle. In one embodiment, a thermocouple is used to measure the temperature about the insert so that the intensity of the heater can be adjusted accordingly. The heater can also be used with nozzles used in multiple nozzle applications to balance the flow of the nozzles.
