|4 Cooling System
The cooling medium of the Automatic Injection Blow Molding Machine is water (shown in Fig 8). The cooling water is divided into four branches from the inlet pipe, One to the oil cooler of the hydraulic system for heat exchanging, one to cool the screw mould, the third to cool the blow mould, The last one to cool the inlet of plastic material. Then several branches converge and drain off. Shut off valves have been used to regulate the flow of water of each branch to bring about the expected effect.
