With the development of scientific and technological progress, like all instries, especially electronics instry is at an alarming pace, and people of electronic procts such as televisions, computers, growing demand. So began a large number of electronic procts shipped worldwide, so the foam packaging procts, is an integral part.
In this paper, EPS molding machine monitoring and control circuit. Mainly through the design of a microcontroller AT89C51 can choose manual control and automatic control of the EPS (expandable polystyrene) foam machine control circuit, complete motor control, feed control, temperature control, air control, pressure control and display control. These are achieved through software programming in assembly language. Simulation part, the AT89C51 microcontroller ports P0.4 P0.0 mouth to use as the key interface circuit. P1.6 P1.0 mouth to mouth as the output interface circuit. P2.2 P2.0 mouth to mouth is used as a sensor interface circuit. P3.2 P3.0 mouth to mouth then display circuit displays the working steps and time. The experimental testing, the machine starts, select Auto, Manual, after the different control in the digital work on the appropriate steps will be displayed and each step requires time workers shows that workers in the corresponding step when there is a corresponding phenomenon. Experiments needed to achieve the desired effect.
After transformation of the future can be used in injection molding machine automatic control.
