Description
смонтированной на основании 1 пресса. После этого опускаетс .ксфнус 1Г гидроцнлиндра 10, а также соединенный-и;ним с помощью траверсы 12-плунжер 6 обогреваемой плавильной камеры 2...mounted on the basis of 1 press. After that, the xfnus 1G of the hydraulic cylinder 10 is lowered, as well as the connected-and; with the help of the traverse, the 12-plunger 6 of the heated smelting chamber 2 ...
Плунжер 6 выдавливает пластифпцировапный термопластичный материал из обогреваемой плавильной камеры 2 через каналы рассекател 4 и отверстие сливного клапана 5 в пресс-форму 8.The plunger 6 squeezes the plastic thermoplastic material from the heated melting chamber 2 through the channels of the dissector 4 and the opening of the drain valve 5 into the mold 8.
После заполнени пресс-формы 8 материалом давление подаетс в верхние полости пневмо- или гидроцилиндров 15 и происходит опускание траверсы 12, плита 13 которой соединена со штоками 14 пневмо- или гидроцилиндров 15, установленного на плите 13 гидродилпндра 10, а следовательно, и подвижного стола 7 с пресс-формой 8. Под действием давлени материала в обогреваемой плавильной камере 2, создаваемого опускающимс вместе с траверсой 12 плунжером 6, опускаетс сливной клапап 5 и прекращаетс выдавливание материала из обогреваемой плавильной камеры 2.After the mold 8 is filled with material, the pressure is supplied to the upper cavities of the pneumatic or hydraulic cylinders 15 and the crosshead 12 is lowered, the plate 13 of which is connected to the rods 14 of the pneumatic or hydraulic cylinders 15 mounted on the plate 13 of the hydrodilpndra 10 and, consequently, of the movable table 7 with the mold 8. Under the pressure of the material in the heated melting chamber 2, created by the plunger 6 descending together with the crosspiece 12, the drain valve 5 is lowered and the material is extruded from the heated melting chamber 2.
После подъема штоков 14 пневмо- или гидроцилиндров 15 в крайнее верхнее положение, а также опускани штока 9 гидроцилиндра 10 в крайнее нижнее положение пресс готов к следующему циклу лить изделий.After lifting the rods 14 of the pneumatic or hydraulic cylinders 15 to the uppermost position, as well as lowering the rod 9 of the hydraulic cylinder 10 to the lowest position, the press is ready for the next cycle of casting products.
В результате надежного запирани сливного канала обогревательной плавильной камеры исключаетс произвольное истечение расплавленного материала и обеспечиваютс безопасные услови труда.As a result of reliable locking of the drain channel of the heating melting chamber, arbitrary outflow of molten material is prevented and safe working conditions are ensured.
