射芯机造芯的工作原理

发布时间:2020-01-11
工作原理是将以液态或固态热固性树脂为粘结剂的芯砂混合料射入加热后的芯盒内,砂芯在热的芯盒内很快硬化到一定厚度(约5~10 mm) 将之取出,得到表面光滑、尺寸精确的优质砂芯成品。 热芯盒射芯机与普通射芯机比较有以下优点: 1 生产效高:热芯盒射芯机工作过程是填砂与紧实同时完成的,并立即在热的芯盒中硬化,一个循环周期仅需十几秒至几十秒,便可生产出供浇铸用的砂芯。 2 砂芯质量好:能射制任何复杂程度的砂芯,而且尺寸精确、表面光洁,从而可以减少铸件加工余量。 3 可以省去很多制芯用辅助设备及工具、如烘芯炉、烘干器、芯骨、腊线等。 4 减轻劳动强度、操作灵活轻便、容易掌握,采用电加热,温度可自动控制,工作地易保持清洁,为制芯过程的机械化、自动化创造条件。 5 如选配气体发生系统,则本机可满足冷芯盒制芯的要求。
The working principle is that the core sand mixture with liquid or solid thermosetting resin as binder is injected into the core box after heating. The sand core is quickly hardened to a certain thickness (about 5~10 mm) in the hot core box and will be removed to get a smooth and accurate quality sand core product. The hot core box core ejection machine has the following advantages compared with the ordinary core ejection machine: 1 the production efficiency is high: the working process of the core box ejection machine is completed at the same time with the sand filling and compaction, and immediately hardened in the hot core box. A cycle cycle only takes more than ten seconds to dozens of seconds, and the sand core for casting can be produced. 2 the quality of sand core is good: it can shoot any complex core sand, and the size is accurate and the surface is bright and clean, so that the casting allowance can be reduced. 3, we can save a lot of auxiliary equipment and tools for core making, such as core drying oven, dryer, core bone, wax line and so on. 4 lighten labor intensity, operate flexibly light and easy to master, use electric heating, temperature can be controlled automatically, the working place is easy to keep clean, create conditions for mechanization and automation of core process. 5 if the gas generation system is selected, the machine can meet the requirements of cold box core making.
