Abstract: The invention relates to a device (1) and a method for measuring the moisture in die cast molds (24), the cavity (25) of which is connected via an evacuation conduit (31) to an evacuation device (28). The modular assembly of the device (1) is connectable to the evacuation conduit (31) and comprises a sensor assembly (S) by means of which the moisture of gases evacuated from the mold cavity (25) is measurable. The sensor assembly (S) comprises an emitter (7) emitting electromagnetic radiation and a detector (14) detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity (25) needs to be altered before the actual casting action.
Abstract translation: 本发明涉及一种用于测量压铸模具（24）中的水分的装置（1），其空腔（25）经由抽空导管（31）连接到排气装置（28）。 装置（1）的模块化组件可连接到排气管道（31）并且包括传感器组件（S），通过该传感器组件，从模腔（25）排出的气体的湿气是可测量的。 传感器组件（S）包括发射电磁辐射的发射器（7）和检测电磁辐射的检测器（14）。 基于抽空动作期间获得的测量值，可以确定喷射到模腔（25）内的水/脱模剂混合物的量是否在实际铸造作用之前被改变。

Abstract: A die casting mold evacuation valve assembly (1) features a two-part valve casing (2). Machined in the front casing part (2a) is an evacuation duct (3, 5) closable by means of an evacuation valve (7). Housed in the casing (2) is an actuator (14) for actuating a valve piston (8) of the evacuation valve (7). The actuator (14) comprises a casting material actuated force transducer (15) and a force transmission member (20) for transmitting the closing movement of the force transducer (15) to the valve piston (8) of the evacuation valve (7). The actuator (14) features in addition a stacked spring assembly (23) for returning the actuator (14) and/or force ejecting the riser. The front casing part (2a) is provided with a sleeve (26) surrounding at least the head part (9) of the valve piston (8) and a further sleeve (31) surrounding at least the head part (16) of the force transducer (15). Both sleeves (26, 31) are harder than the front casing part (2a).
Abstract translation: 压铸模具排气阀组件（1）具有两部分阀壳（2）。 在前壳体部分（2a）中加工的是通过抽气阀（7）可关闭的排气管道（3,5）。 位于壳体（2）中的是用于致动抽空阀（7）的阀活塞（8）的致动器（14）。 致动器（14）包括铸造材料致动力传感器（15）和用于将力传感器（15）的关闭运动传递到排气阀（7）的阀活塞（8）的力传递部件（20）。 致动器（14）另外还具有用于使致动器（14）返回和/或强制弹出立管的堆叠式弹簧组件（23）。 前壳体部分（2a）设置有至少围绕阀活塞（8）的头部部分（9）的套筒（26），以及至少围绕力部分（16）的另一个套筒（31） 传感器（15）。 两个套筒（26,31）比前壳体部件（2a）更硬。
