    • A coinjection molding apparatus (100) includes a manifold (112), a nozzle body (204) coupled to the manifold, a sleeve (124) disposed within the nozzle body and defining an outer melt channel between the sleeve (124) and the nozzle body (204), a pin (126) disposed within the sleeve (124) and defining an inner melt channel between the pin (126) and the sleeve (124), and a nozzle tip having an alignment portion contacting the sleeve (124). The sleeve (124) is actuated to open and close melt communication of the outer melt channel and a cavity gate. The pin (126) is actuated to open and close melt communication of the inner melt channel and an opening of the sleeve (124). The alignment portion aligns the sleeve (124) with the cavity gate along the actuated range of the sleeve (124).
    • 共注射成型设备(100)包括歧管(112),联接到歧管的喷嘴体(204),设置在喷嘴体内并且在套筒(124)和喷嘴之间限定外部熔体通道的套筒(124) 主体(204),设置在套筒(124)内并且在销(126)和套筒(124)之间限定内部熔体通道的销(126))和具有与套筒(124)接触的对准部分的喷嘴尖端 。 套筒(124)被致动以打开和关闭外部熔体通道和空腔浇口的熔融连通。 销(126)被致动以打开和关闭内部熔体通道和套筒(124)的开口的熔融连通。 对齐部分沿着套筒(124)的致动范围使套筒(124)与空腔门对准。

    • An injection molding apparatus (100) includes an injection manifold (102) having a melt channel (112). A hot runner injection nozzle (110) includes an axial melt channel (142) extending along a central axis (144) and communicating with the manifold melt channel (112). The nozzle further includes at least two angled melt channels (158) disposed at an angle to the central axis. At least two nozzle tips (162) are provided, and each includes a nozzle tip melt channel (160) in communication with one of the angled melt channels. An axial valve (184) pin is disposed coaxially with the central axis and is disposed outside of the axial melt channel. Lateral valve pins (188) movable within the nozzle tip melt channels are disposed at an angle to the valve pin. A linkage system (192,194) connects the lateral valve pins to the axial valve pin. Movement of the axial valve pin is transmitted through the linkage system to the lateral valve pins to open and close communication between the nozzle tip melt channels and the lateral mold gates.
    • 注射成型设备(100)包括具有熔体通道(112)的注射歧管(102)。 热流道注射喷嘴(110)包括沿着中心轴线(144)延伸并与歧管熔体通道(112)连通的轴向熔体通道(142)。 喷嘴还包括与中心轴成一定角度设置的至少两个成角度的熔体通道(158)。 提供至少两个喷嘴尖端(162),并且每个包括与一个成角度的熔体通道连通的喷嘴尖端熔体通道(160)。 轴向阀(184)销与中心轴线同轴设置并且设置在轴向熔体通道的外部。 在喷嘴末端熔融物通道内可移动的横向阀销(188)以与阀销成角度的方式设置。 联动系统(192,194)将侧向阀销连接到轴向阀针。 轴向阀销的运动通过联动系统传递到侧向阀销,以打开和关闭喷嘴末端熔体通道和侧模浇口之间的连通。
