If no, open the flange plates on both sides of the pressure head and check whether the Y-shaped seals on both sides of the frame are aging and deformed.
如无上述情况，打开压力头两侧法兰板，检查机架两侧y型密封圈是否老化变形。
If so, the pressure head is slow.
如果是这样，压力头是缓慢的。
The fifth stage: open the back end flange plate of the die head, check whether the gear bearing butter has deteriorated, if it has deteriorated, wash with kerosene or gasoline, and move the die head at the same time, it will feel more and more loose.
第五阶段：打开压模头后端头法兰板，检查齿轮轴承黄油是否变质，若变质，用煤油或汽油冲洗，同时移动压模头，会感到越来越松。
Sand shooting is mainly the use of compressed air for pre-compaction, if there is no real situation, mainly due to insufficient air pressure or equipment sand shooting system design defects.
射砂主要是利用压缩空气进行预紧实，如果出现不实的情况，主要是空气压力不够或者设备射砂系统设计缺陷导致。
The sand shooting system of the automatic molding machine adopts the world's most advanced layered, all-round independent air intake and exhaust design, which fundamentally solves the problem that the sand shooting of similar models in the same industry is not in place and the sand shooting cylinder is easy to plug.
全自动造型机的射砂系统采用目前世界上最先进的分层式、全方位独立进气和排气设计，从根本上解决了同行同类机型射砂不到位和射砂筒容易堵塞的问题。
The unit gas supply system is adopted to ensure that the sand shooting system and mechanical system of the whole machine can run normally and stably.
采用了单元化供气系统，确保整台机的射砂系统、机械系统均能够正常稳定的运行；
The oil pressure system adopts intelligent drive servo motor and oil research control valve, as well as all kinds of oil cylinders of the American Sun brand, which is stable and reliable and has long service life.
油压系统采用智能驱动伺服电机和油研控制阀，以及美国太阳牌各类油缸，使用稳定可靠、使用寿命长。
