【摘要】 高密度无箱挤压造型是当今铸造行业造型领域最佳的造型技术,特别是精密铸造。造型机可按照自动循环指令完成射砂、压实、起型、推出合型、起型、合型等工序的自动循环工作过程,其中控制系统由电、气、液联合构成。控制系统主要由触发器、电子逻辑元器件及继电器组成的步进式顺控器作为核心,行业内专业技术人员应该从其结构、I/O设计及动作执行及程序编制方面深入地研究,以提高造型机的安全性和工作效率。更多还原

【Abstract】 High-density flaskless extrusion modeling is the best technology in casting industry modeling, especially in precision casting. Molding machine can carry out the automatic cycle of processes such as sand shooting, compaction, forming, launch mold, forming, mold assembling in accordance with the automatic cycle instruction. The control system consists of electricity, gas and liquid. Control system mainly takes the stepping sequence control device which is composed of the trigger, electronic logic components and relay as the core. The professionals in this industry should carry out further research in the aspects of its structure, I / O design, execution of action and programming, so as to improve the safety and work efficiency of the molding machine.更多还原
