冷芯盒射芯机是采用向芯盒内通气硬化砂芯工艺，具有如下优点：砂芯精度高，表面粗糙度低；硬化时间短，生产率高；不需加热，节省能耗；常温下工作，改善了劳动条件；出芯后不到一小时即可浇注，减少贮存面积；没有过硬化问题，容易制作壁厚差异大的砂芯；对芯盒的材料要求较低；浇筑后易溃散，落砂性能好。
The cold core box core ejection machine is used in the core box, which has the following advantages: high core precision, low surface roughness, short hardening time and high productivity, without heating, saving energy, working at normal temperature, improving working conditions, pouring and reducing storage area less than one hour after the core is out of the core; The problem of over hardening makes it easy to make sand cores with large wall thickness. The material requirements for the core box are low, and it is easy to collapse after pouring, and the sand falling property is good.
