摘要本文为沙箱成型机的液压系统设计，为沙箱成型机设计液压传动系统是此次的目的。本次的设计是先查阅资料，了解一些沙箱成型机的知识和它的工作过程。经过。对它的运动进行了解分析，根据液压系统设计计算过程，对本次的设计进行计算，计算出需要运用到的数据，需要用的辅助元件对其进行选型。根据沙箱成型机的运动，画出它的液压原理图使它来完成这种运动。51247
本次设计设计出了用来压制造模和顶出模型的三个液压缸的技术数据，对油箱进行了设计，最后将油箱，泵，各种阀类元件通过管道装配成一个液压站，用来形成一个完整的液压系统。系统运行时，压制缸通过油液的作用向下压制，使箱体内的砂体成型，待砂体成型完毕，沙箱成型机下面的顶模缸就会因为油液的作用将造好的模顶出。造出符合条件的铸件。

Abstract
This article is Sandbox forming machine hydraulic system design, molding machine hydraulic system is the design purpose.
This design is the first access to information, the knowledge to understand some molding machine and its working process. After understanding of its movement analysis, based on the hydraulic system design and calculation process for the design of this calculation, applied to calculate the required data, you need to use its auxiliary components selection. According to the movement of the molding machine, hydraulic schematic diagram draw it makes it to complete this movement.
This design is used to design a manufacturing mold and ejector pressure model three hydraulic cylinders technical data, fuel tank has been designed, and finally the fuel tank, pump, various valves through the pipeline components assembled into a hydraulic station, with the to form a complete hydraulic system. The system is running, pressing down the role of the oil tank through repression, the cabinets sand molding, molding sand to be completed, the following top mold molding machine cylinder will be because of the oil will make a good role model ejector . Early in the morning qualifying castings.
Keywords: Sandbox forming machine; Hydraulic control system;hydraulic cylinder.
