射芯机的操作方法
Operation method of core shooting machine
一、在覆膜砂射芯机运转之前
1. Before the operation of coated sand core machine.
1、清除妨碍射芯机设备正常运转的障碍物。
1, remove obstacles that interfere with the normal operation of the core equipment.
2、按润滑卡规定，对设备进行润滑。
2. Lubricate the equipment according to the lubrication card.
3、检查射芯机设备关键部位的紧固件是否紧固，如有松动，必须紧固好。

5、拧开压缩空气总伐，对射芯机设备进行空载试车。在这个过程中，要检查机构的动作是否正常， 检查各个伐门的管路是否漏气。
5, unscrew the compressed air total cutting, and carry out the no-load trial run for the core shooting equipment. In this process, check whether the action of the mechanism is normal, check whether the pipeline of each valve is leaking.

二、在操作覆膜砂射芯机的过程中
Two. During the operation of coated sand core machine

1、射芯机开动以后，操作人员不得擅离工作岗位，应集中思想，按工艺程序，认真进行操作，但不许同时操作两个伐门。
1. After the core-shooting machine starts, the operator must not leave his post without permission. He should concentrate his mind and operate it conscientiously according to the technological procedure, but he must not operate two valves at the same time.
