摘要：
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).
