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 swing and the movement is slow and slow, and the molding machine should be maintained according to 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, molding machine fault detection, check molding machine pressure head, front and rear plate clearance, whether there is any iron ballast and other foreign body obstruction, can be cleared after the test run.

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 on the head behind the two inlet pipe, the control valve respectively pull in in situ and put into, look at the orifice of the inlet is large enough, if a small amount of intake will cause pressure swing slowly, molding machine fault detection, if the reason may have been to check the control valve, until the air filter air is blocked.

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。

3, molding machine pressure head has a cover plate, open the observation rack is serious corrosion, if this molding machine fault, the same will cause pressure head action is slow, can use kerosene or gasoline cleaning can.

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 above situation did not happen, should open the pressure head on both sides of the flange, check the rack on both sides of the Y sealing ring is aging and deformation, such as, can also cause pressure head slow.

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, opened in molding machine head after upper flange, check the gear bearing the butter is bad, if it is available, kerosene or gasoline washing, while moving the head, will feel more and more loose.
