摘要： It is well-known to use one or more valve actuators in injection molding equipment. However, problems are obtained when the valve stem of the valve actuator is no longer usable, for example, due to wear and/or breakage. In conventional arrangements, the whole valve assembly is removed and the valve stem is replaced. However, as each valve has an optimum length for the associated valve stem, replacement of a valve stem by one which is too long or too short impairs the operation of the equipment. Described herein is an adjustable valve stem apparatus (10) adapted for use in an injection molding equipment or device comprises a cylindrical body (12) comprising internally threaded fixed portion (14) and moveable portion (16) threadably mounted on a double-ended screw (30). Moveable portion (16) has a means (26) for removably mounting a valve stem (28) which communicates with a mold cavity. The double-ended screw (30) has a socket (38) formed in its top portion for adjusting the moveable portion (16) relative to the fixed portion (14) thereby correspondingly axially displacing the valve stem (28) from a first to second position relative to the mold cavity.

摘要翻译： 在注塑设备中使用一个或多个阀门执行器是众所周知的。 然而，当阀致动器的阀杆不再可用时，例如由于磨损和/或断裂而获得问题。 在常规布置中，整个阀组件被移除并且阀杆被更换。 然而，由于每个阀具有用于相关阀杆的最佳长度，所以阀杆的更换太短或太短会损坏设备的操作。 这里描述的是适用于注塑设备或装置的可调节阀杆装置（10），其包括圆柱形主体（12），其包括内螺纹固定部分（14）和可螺纹地安装在双头螺钉上的可移动部分（16） （30）。 可移动部分（16）具有用于可拆卸地安装与模腔连通的阀杆（28）的装置（26）。 双头螺钉（30）具有形成在其顶部中的插座（38），用于相对于固定部分（14）调节可移动部分（16），从而相应地使阀杆（28）从第一到第二 相对于模腔的位置。
