Injection molding machine based on configuration
software PLC control system design
Abstract : Referred to as plastic injection moulding machine, forming machine, one-time
precision molding of complex products. With the progress of society, plastic products are widely
used in all fields, in everyday life is everywhere, even in many aspects of the military also used
injection molding products, at present injection moulding machines have become the mainstream
of injection molding and machining equipment. Traditional use of relays, contactors, as electric
control system of medium and small injection moulding machine control system's shortcomings
have become increasingly prominent, mainly for: line complex, short relay for life, the movement
has been slower, precision control systems are not allowed, while the failure rate is high,
maintenance is difficult, and so on. For the above problem, this graduation design of injection
molding machine control system based on configuration software using PLC control system. This
paper analyzes the structure and work process of injection machine and Siemens S7-200 PLC
programming techniques and how to use them, a brief introduction. And simulation using
kingview software combination monitor, designed a complete injection molding machine control
system.
