注塑机检查运行中的模具是否处于正常状态：是否有低压锁模保护；活动部位如导柱、顶杆、行位是否磨损，润滑是否良好？要求至少12小时要加一次油，特殊结构要增加加油次数。模具的固定模板的螺丝和锁模夹是否松动；生产正常状况：检查产品的缺陷是否与模具有关；下机时要对模具进行全面检查并进行防锈处理：抹干型腔、型芯、顶出机构和行位等部位水份并喷洒模具防锈剂或涂抹黄油。下机后的模具要放在指定地点并作好记录：（1）模具状况：完好还是待修。（2）下模时的防锈处理方式。
Check whether the mold in operation is in normal state: whether there is low-pressure mold locking protection; whether the movable parts such as guide pillar, ejector pin and row position are worn, and whether the lubrication is good? It is required to add oil at least once every 12 hours, and the number of times for special structure should be increased. Whether the screw and lock clamp of the fixed template of the mold are loose; normal production condition: check whether the defects of the product are related to the mold; when getting off the machine, the mold should be comprehensively inspected and antirust treatment should be carried out: dry the water in the cavity, core, ejection mechanism and row position, and spray the mold antirust agent or grease. The mold should be placed at the designated place and recorded: (1) mold condition: intact or to be repaired. (2) Anti rust treatment method for lower die.
