冷芯盒射芯機(jī)是采用向芯盒內(nèi)通氣硬化砂芯工藝，具有如下優(yōu)點(diǎn)：砂芯精度高，表面粗糙度低；硬化時(shí)間短，生產(chǎn)率高；不需加熱，節(jié)省能耗；常溫下工作，改善了勞動(dòng)條件；出芯后不到一小時(shí)即可澆注，減少貯存面積；沒(méi)有過(guò)硬化問(wèn)題，容易制作壁厚差異大的砂芯；對(duì)芯盒的材料要求較低；澆筑后易潰散，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.
