System Design of Mold Opening and Closing Device of Hollow Blow Molding Machine Based on PLC
In order to improve the production quality and efficiency of blow molding products,improve the automation degree of blow molding production process and reduce the labor intensity,a set of mold opening and closing device of double-station hollow blow molding machine was designed,and its hydraulic system and electrical system were designed.Through the design of the overall scheme of the mold opening and closing device combined with its workflow,in the aspect of control system hardware,the overall scheme of the control system was first established,the PLC model was selected,the circuit wiring diagram and I/O distribution table were designed;in the aspect of control system software,the control system program was written and touch screen was made in TIA Portal V16 environment.Finally,it was compiled in the upper computer to realize human-computer interaction and system debugging.The results show that the operation accuracy and automation of the mold opening and closing device under this system are improved,the production quality of blow molding products is improved,and the production cycle of products is shortened to meet the require-ments of industrial production.
