Description
лотнитель 7 на большей части хода прессовани не контактирует со штоком 1, что обеснечивает наименьший износ уплотнени и высокую надежность герметизации, а также снижение простоев оборудовани .The lanyard 7 does not come into contact with the rod 1 for the greater part of the pressing stroke, which ensures the least wear of the seal and high reliability of sealing, as well as reduced equipment downtime.
Устройство позвол ет повысить надежность герметизации камеры прессовани и обеспечить работу вакуумной машины дл лить под давлением с горизонтальной холодной камерой прессовани , заполн емой расплавом путем вакуумного всасывани .The device makes it possible to increase the reliability of the sealing of the pressing chamber and to ensure the operation of the vacuum injection molding machine with a horizontal cold pressing chamber filled with melt by vacuum suction.
Предмет изобретени Subject invention
Устройство дл герметизации камеры прессовани , заполн емой расплавом путем вакуумного всасывани , содержащее камеру прессовани , прессующий поршень со штоком и уплотнитель, отличаюшеес тем, что, с целью повышени надежности герметизации камеры прессовани и использовани штока в качестве дроссел , шток выполнен ступенчатым , причем прессующий поршень установлен на торце ступени большего диаметра.A device for sealing a pressing chamber filled with melt by vacuum suction, comprising a pressing chamber, a pressing piston with a rod and a sealant, characterized in that, in order to increase the reliability of the sealing of the pressing chamber and use the rod as a throttle, the rod is stepped, and the pressing piston installed at the end of the tread of a larger diameter.
