造型机是能完成填砂、紧实、起模等主要造型工序或至少完成紧实工序的机器。用于制造砂型的铸造设备。它的主要功能是：填砂，将松散的型砂填入砂箱中；紧实型砂，通过震实、压 造型机实、震压、射压等不同方法使砂箱中松散的型砂紧实，使砂型在搬运和浇注等过程中具有必要的强度；起模，利用不同机构将模样从紧实后的砂型中取出。 The moulding machine is the machine which can complete the main molding process, such as filling, compacting, molding, etc., or at least the compacting process. Foundry equipment used to make sand mold. Its main function is: filling sand, filling the sand box with loose sand; Compact sand is compacted, and the loose sand is compacted in the sand box by means of vibration, compaction, shock pressure and ejection pressure, so as to make the sand mold necessary in the process of handling and pouring. The shape of the mold is taken out of the sand shape of the compacted shape. 造型机在使用一段时间后，压头可有能出现摆动动作迟钝、缓慢、应按下列方法进行造型机保养。 After using the molding machine for a period of time, the pressure head can be slow and slow, and the machine should be maintained by the following methods. 1、造型机故障检测时，检查造型机压头前后板间隙，是否有什么铁碴等异物阻碍，可清除后试车。 1. During the machine failure detection, check the gap between the front and back plates of the molding machine, and if there is any obstacles such as iron balling, can be cleared and test the car. 2、打开压头上后面两根进气管，操纵阀分别扳在原位与摆入，看看管口进气是否够大，如果进气量小也会造成压头摆动缓慢，造型机故障检测时，若是此原因可一直检查到操纵阀，直致空气滤清气，是否堵塞。 2, open the pressure head behind two inlet pipe, control valve pull in in situ and put into the respectively, and see whether the nozzle inlet is enough big, if small air inflow also causes pressure head swinging slowly, molding machine fault detection, if the reason for this can always check to control valve, straight to the air filtration, blockage. 3、造型机压头上面有盖板，打开观察齿条是否锈蚀严重，如果发生此造型机故障，同样会造成压头动作迟钝，可用煤油或汽油清洗即可。 Opening the top cover plate, 3, molding machine head observe whether rack is corroded seriously, in the event of the molding machine fault, also can cause head moves slow, can use kerosene or gasoline wash. 4、造型机故障检测时，若上述情况都没发生，就应打开压头两侧法兰盘，检查齿条两侧Y型密封圈是否老化、变形，如是，也可造成压头缓慢。 4, molding machine fault detection, if the situation doesn't happen, you should open the pressure head on both sides of the flange, check whether the rack on both sides of the y-shaped sealing ring is aging, deformation, so, also can cause pressure head slowly. 5、最后一招，打开位于造型机压头后上端法兰盘，检查齿轮轴承的黄油是否变质，如果是这样，可用煤油或汽油冲洗，同时搬动压头，会感觉越来越松。 5, a last resort, open in the molding machine head after the upper flange, check whether the gear bearing butter is bad, if so, can use kerosene or gasoline wash, lift head at the same time, will feel more and more loose.
