2 Hydraulic System
In this Automatic Injection Blow Molding Machine, hydraulic system (shown in Fig.6) has been used to operate the screw driving, injection, injection mould clamping, the opening and closing of the blow mould, the core in and out etc. The oil pump is soaked under hydraulic oil of the tank. The filter is set up at the inlet of the oil pump, and oil flows back to tank through heat exchanger and oil scavenger.
The operation pressure of the system can be adjusted in the range of 80 to 120 bars. Before the Automatic Injection Blow Molding Machine left our workshops, it has been adjusted well, please don't change it randomly. If the change is necessary, the pressure should be adjusted as low as possible according to the material and technique requirements in order to make for a long lasting and economical machine.
Note: This Automatic Injection Blow Molding Machine is a hydraulic system using double electromagnetic proportional valve, the adjustment of pressure and flow can refer to the electrical control system. |
