摘要： An injection mold for an injection molding machine includes a first mold half having one of at least one mold cavity and at least one mold core. The first mold half is mounted on a rotatable turret block rotatable on an axis perpendicular to the central axis of the first mold half for rotating the at least first mold halves thereof into alignment with the second mold half. The first mold half is moved towards and away from the second mold half via means for moving, wherein the second mold half is stationary and supported by a frame. The rotatable turret block is further for clamping the first mold halves and the second mold half together.

摘要： The present invention relates to an improved apparatus for forming injection molded plastic articles having an inner wall portion. The apparatus includes a mold cavity portion (112) and a mold core portion (118) defining a cavity space (124) in the shape of the plastic article to be formed. The apparatus further includes at least two hot runner nozzles (132,132 ' ,132 '' ) for injecting molten plastic material into the cavity space. The nozzles are preferably offset to outer portions of the mold core portion so as to provide an increased space (A ' ) in the mold core portion in which cooling conduits (142), inlets and the like can be placed to increase the cooling capability of the mold core portion. The offsetting of the nozzles also provides the mold core portion with increased strength. Each of the nozzles communicates with an inner wall portion of the cavity space via a hook-shaped passageway (138,138 ' ,138 '' ) and an inside gate (134,134 ' ,134 '' ). Additionally, each of the nozzles has a metal portion (152,152 ' ,152 '' ) for maintaining plastic material in the hook-shaped passageway in molten condition.
摘要翻译：本发明涉及一种用于形成具有内壁部分的注射成型塑料制品的改进装置。该设备包括模具腔部分（112）和模芯部分（118），其限定待形成的塑料制品形状的空腔（124）。该装置还包括至少两个用于将熔融塑料材料注入空腔中的热流道喷嘴（132,132'，132“）。喷嘴优选地偏置到模芯部分的外部部分，以便在模芯部分中提供增加的空间（A'），在模芯部分中可以放置冷却导管（142），入口等，以增加冷却能力模芯部分。喷嘴的偏移还为模芯部分提供了增加的强度。每个喷嘴经由钩形通道（138,138'，138“）和内部门（134,134'，134”）与空腔空间的内壁部分连通。此外，每个喷嘴具有用于在熔融状态下将塑料材料保持在钩形通道中的金属部分（152,152'，152“）。

摘要： A sprue bar assembly for a melt transfer system for stack molds comprises a sprue bar (260,268) and a sprue bar sleeve (264,272), a sprue bar and drool restrictor (748) and sleeve or a sprue bar and (260,268) drool restrictor (748). For the assemblies with the sleeve, when the stack mold is opened, the sprue bar slides inside the sprue bar sleeve which captures any leakage therefrom. When the mold is closed, the sprue bar sweeps captured leakage out of the sleeve to an area outside the mold. As the bushing (276,280) at the end of the sprue bar can contact the nozzle (308) of the injection machine at a point very close to the edge of the fixed platen, the resulting minimum length of the sprue bar is reduced, reducing pressure losses through the sprue bar and reducing the cost of the sprue bar. The sprue bar sleeve can be fabricated from an insulating material to enhance the thermal characteristics of the sprue bar assembly and a scraper can be provided on the sprue bar to improve removal of captured material from the sprue bar sleeve. If a drool restrictor is provided within the bushing, the amount of drool from the sprue bar when the bushing is not in engagement with the nozzle of the injection machine can also be reduced and, in some circumstances, can eliminate the need for the sleeve.
摘要翻译：用于堆叠模具的熔体传送系统的浇道棒组件包括浇道棒（260,268）和浇道棒套（264,272），浇口棒和流涎限制器（748）以及套筒或浇道棒和（260,268）流涎限制器（260,268） 748）。对于带有套筒的组件，当堆叠模具打开时，浇道棒在浇道棒套筒内滑动，从而捕获任何泄漏。当模具关闭时，浇道棒将捕获的泄漏物从套筒中扫出到模具外部的区域。当浇口棒端部的衬套（276,280）可以在非常靠近固定台板边缘的位置与注塑机的喷嘴（308）接触时，浇口棒的所得最小长度减小，从而减小压力通过浇道棒损失并降低浇道棒的成本。浇道棒套筒可以由绝缘材料制成以增强浇道棒组件的热特性，并且可以在浇道棒上设置刮板以改善从浇道棒套筒上移除捕获的材料。如果在衬套内设置流涎限流器，则当衬套不与注射机的喷嘴接合时，来自浇道棒的流涎的量也可以减少，并且在某些情况下可以消除对套筒的需要。
