摘要： The invention is directed to a process to manufacture an interconnected stack of thermoplastic frames having two sides by stacking the thermoplastic frames to obtain a stack of frames such that the facing sides of two neighbouring frames are in contact with each other at a contact area. When stacking a longitudinal conduit is formed which runs along the length of the stack and a branched conduit is formed at the contact area. The interconnected stack of thermoplastic frames are obtained by supplying a pressurised melt of a plastic material to the elongated conduit and branched conduits.

摘要： The invention provides a method for manufacturing a substrate-integrated gasket, the method integrating a fiber substrate which is constructed by a pulp fiber having cellulose as a main component and a gasket body which is constructed by a rubber-like elastic body according to a rubber impregnation, wherein a plurality of substrate-integrated gaskets are obtained by executing an injection molding by plural stages of rubber metal molds. Further, the rubber material is filled in plural stages of metal mold cavities by passing the rubber material through the fiber substrate in which a rubber material flow channel in the metal mold is closed at its injection pressure. The invention can reduce a man hour for removing burr and cleaning a metal mold by suppressing generation of rubber burr at the molding time and can reduce an amount of disposal of a molding material, thereby achieving a good manufacturing efficiency.

摘要： A shut-off valve for preventing drool from an injection molding apparatus is provided in a melt channel of a sprue bushing. The shut-off valve includes a fixed member located in the melt channel and a reciprocating member coupled to the fixed member. The reciprocating member is biased toward an extended position in which an inlet of the sprue bushing is blocked thereby. The reciprocating member is movable from the extended position towards a retracted position in which the inlet of the sprue bushing is clear by the force of a melt stream entering the melt channel of the sprue bushing.

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： A mold carrier (61) contains a fluid distribution system, such as a hot runner system (60), having a nozzle (76) with a substantially flat face (80, 82). The hot runner system includes melt channels (66-70) that require alignment with a complementary melt channel (96) within an interface adaptor, such as a sprue bushing (92), that permits coupling of the hot runner system to a mold (62, 64). The sprue bushing (92) also has a flat sealing surface that is arranged to abut, in use, against the substantially flat face (80, 82) of the nozzle (76) to provide an interface. Under appropriate positive biasing (88), the flat faces of the nozzle (76) and sprue bushing (92) produce a substantially flat interface that maintains sealing contact in the face of potential radial misalignment between the various melt channels. The interface is recessed within a boundary defined by a mold locating ring (100), thereby protecting the nozzle from damage during loading of a mold into the mold carrier (61). The nozzle's face may include a step that causes a recessing of a body portion of the nozzle relative to the actual interface produced to the sprue bushing.
摘要翻译：模具载体（61）包含流体分配系统，例如热流道系统（60），其具有具有基本平坦的面（80,82）的喷嘴（76）。热流道系统包括熔融通道（66-70），其需要与接口适配器（例如浇道套管（92））内的互补熔体通道（96）对准，其允许热流道系统与模具（62 ，64）。浇道衬套（92）还具有平坦的密封表面，其被布置成在使用中抵靠喷嘴（76）的基本平坦的表面（80,82）以提供界面。在适当的正偏压（88）下，喷嘴（76）和浇道套管（92）的平面产生基本上平坦的界面，其保持面对各种熔体通道之间的潜在的径向不对准的密封接触。界面凹陷在由模具定位环（100）限定的边界内，从而在将模具装入模具托架（61）期间保护喷嘴免受损坏。喷嘴的表面可以包括使得喷嘴的主体部分相对于产生到浇道套筒的实际界面的凹陷的步骤。
