摘要： An external sprue bar position alignment device is comprised of a mounting bracket and a sprue bar alignment frame that is attached to the mounting bracket. The sprue bar alignment frame and mounting bracket define a channel configured to receive a sprue bar upon a mold closing. The sprue bar alignment frame and the mounting bracket are disposed to maintain alignment of an end of the sprue bar with an injection nozzle. The device includes an adjustment device, said adjustment device provided for movement of at least one of the mounting bracket or the sprue bar position alignment frame relative to a path of the sprue bar such that at least one of the mounting block or the sprue bar position alignment frame may bias the sprue bar in a selected direction upon the molding closing. The sprue bar position alignment device may be adjusted without disassembling the mold.

摘要： According to the present invention, a cross over nozzle (10) is provided of two parts (22,24) which, when joined, define a housing (20) having a passage (30) extending therethrough, a tapered valve seat (50) extending about the passage and a value member (60) having a tapered valve head (62) disposed in the passage for engaging the valve seat. The two parts (64,66) are axially separable at an interface (68) extending through the valve seat/valve head. In order to open the valve, both valve parts are first joined and then moved together as one member in the same direction relative to the housing axially away from the valve seat. Similarly, the valve members are jointly moved into engagement with the valve seat before the cross over nozzle is separated. Accordingly, unlike the valve gate design, the valve interface between the two parts of the valve head isn't exposed to molten resin and therefore molten resin isn't trapped therebetween to cause a string upon opening.
摘要翻译：根据本发明，十字喷嘴（10）设置有两个部分（22,24），当两个部分（22,24）接合时，限定了具有延伸穿过其中的通道（30）的壳体（20），锥形阀座（50）围绕通道延伸并且具有设置在通道中用于接合阀座的锥形阀头（62）的值构件（60）。两个部分（64,66）在延伸穿过阀座/阀头的界面（68）处可轴向分离。为了打开阀门，两个阀部件首先接合，然后作为一个构件以相对于壳体轴向远离阀座的相同方向一起移动。类似地，在交叉喷嘴分离之前，阀构件共同地与阀座接合。因此，与阀门设计不同，阀头的两部分之间的阀接口不暴露于熔融树脂，因此熔融树脂不被夹在其间，从而在打开时产生一串。

摘要： A nozzle for controlling flow of melt in a mold assembly comprises a valve pin guide interposed between a nozzle inlet and nozzle outlet, a valve pin movably supported thereby, and a contact arm engaging the valve pin and transverse to and passing through the valve pin guide. Biasing means acting on the contact arm hold the valve pin in a position preventing flow of melt. As the mold assembly closes, forces exerted on the contact arm overcome the biasing means and allow the valve pin to move to a position permitting flow of melt. Relief of pressure of retained melt is effected when force therefrom exerted on the valve pin exceeds an adjustable pre-load of the biasing means. The nozzle advantageously comprises an inlet bushing movably supported by the nozzle body enabling adjustment of the overall length of the nozzle to accommodate a range of spacing of elements of the mold assembly.
摘要翻译：用于控制模具组件中的熔体流动的喷嘴包括插入在喷嘴入口和喷嘴出口之间的阀销引导件，由其可移动地支撑的阀销以及接合阀销的横向并穿过阀销引导件的接触臂。作用于接触臂的偏压装置将阀销保持在防止熔体流动的位置。当模具组件关闭时，施加在接触臂上的力克服偏压装置，并允许阀销移动到允许熔体流动的位置。当施加在阀销上的力超过偏置装置的可调预载荷时，保留熔体的压力的释放是有效的。喷嘴有利地包括由喷嘴主体可移动地支撑的入口衬套，其能够调整喷嘴的整个长度以适应模具组件的元件的间隔范围。

摘要： Methods and apparatus adjustably control the repositioning of non-homogeneous fluid conditions across the stream of a laminar flowing fluid to a desirable circumferential position. The invention is particularly applicable to controlling non-homogeneous melt conditions in hot or cold runner systems. Various mechanisms are provided that enable simple adjustments of a flow diverter within a fluid rotation device, making either static or dynamic adjustments, so that the degree of fluid flow repositioning in a runner system can be changed without the need for mold disassembly or retooling. Various forms of actuators effect adjustment and may be manually manipulated or manipulated through various powered devices.

摘要： A melt distribution system for a four-level stack mould which avoids the use of a central spruebar extending axially along the moulds. The melt distribution system incorporates leg manifolds for registering with an injection machine nozzle to divert melt radially outwardly from the injection machine nozzle. A first conduit extends from the leg manifold parallel to but axially spaced apart from a mould axis to a central distribution block. Melt is bifurcated in the central distribution block to respective crossover conduits extending from opposite sides of the central distribution block. The crossover conduits are generally parallel to but spaced apart from a mould axis. The crossover conduits fluidly communicate with first and second main manifolds in which melt flow is directed to respective injection nozzles.
