The system model of the composite squeeze casting forming system established provides the basis for the production logistics simulation of large parts. Logistics simulation technology can make overall planning for the whole production logistics system in the early stage of production, such as productivity, operation time of each process, average waiting time, etc. The production logistics system of composite squeeze casting includes melt conveying system, mold filling system and part taking system. In these systems, many automatic devices are integrated for auxiliary production, such as spraying device, pneumatic conveying device, part taking device, etc. the work and coordination of these devices have a great impact on the smooth operation of the production logistics system. At the same time, due to the mature development of these auxiliary devices, various models are uneven, and how to select and configure working parameters needs to be studied before production. Therefore, it is necessary to simulate and analyze the production logistics system of composite squeeze casting.
Taking the compound squeeze casting production logistics system as the research object, firstly, the simulation purpose is analyzed. Secondly, the working time sequence of each device in the system is modeled. Finally, the simulation model of the compound squeeze casting production logistics system for large parts is established, and the coordination relationship of each device is analyzed.
