Stability factors of nitrogen gas spring in mold work

Time:2021-05-23    Edit by TengFei

Nitrogen gas springs require considerable stability and reliability both in operation and installation. Because of its high elastic pressure, a nitrogen gas spring can release a force of several kn to several tens of kn in a small volume, and this process is repeated continuously, so it is very important to maintain the stability of its work. When installing and tightening, it must be very firm, especially when the nitrogen gas spring is reversed or installed on the upper mold. The gas spring needs to move continuously with the movement of the slider. Only a firm connection can ensure its normal and stable work.


Therefore, when designing and installing nitrogen gas springs, a certain depth of installation counterbore is opened in the cylinder or piston rod to ensure accurate positioning and avoid tilting. Designers need to consider this in the mold structure to meet this requirement. . Unstable installation will cause damage to the nitrogen spring and unnecessary loss of the mold. In severe cases, it may cause danger. We must pay full attention to this when we use the nitrogen spring. The installation and fastening of the nitrogen spring in the mold is very important.

The general principles of nitrogen spring installation and fastening are as follows:

1: The force of the nitrogen gas spring should be balanced and try to avoid unbalanced load;

2: The installation should be firm, reliable and stable;

3: Cannot be installed at an angle. It is best to have counterbores on the seat plate. The depth can be determined according to the specific conditions of the template. This can prevent the nitrogen gas spring from moving when it is working, and also minimize the mold space it occupies.
