How to choose a mold gas spring?

Mold gas springs have been widely used in advanced mold manufacturing. It can improve the lifespan of the mold and simplify mold design. Over the years, the demand for molds in industrial products has been continuously increasing. Volume, elasticity, service life, and elastic pressure are important indicators for measuring mold springs. Mold gas springs stand out among many mold springs due to their small size (saving mold space), high elasticity (reducing the number of springs), and long service life (reducing mold maintenance times). So, how to choose a mold gas spring?
The selection of mold gas springs can be based on the following four aspects:
1. Selection of elastic pressure of mold gas spring
When selecting and applying gas springs in mold design, the problem encountered is that when selecting gas springs in mold design, the gas spring technology should consider its own characteristics and certain application scope, and correctly limit the application scope of the technology. In order to fully utilize its role and achieve ideal results.
2. Selection of characteristic curves for mold gas springs

For different stamping processes, there are different process requirements. When selecting the mold gas spring process, the process requirements should be met. But from an economic perspective, its impact is greater because the price of the mold gas springs produced by each factory is related to their performance. For the same elastic pressure, gas springs are more expensive than variable force springs. The longer the stroke of a gas spring of the same specification, the higher its price.
Therefore, it is necessary to choose different gas spring characteristic curves based on different process requirements to obtain good prices and economic benefits.
In order to ensure the smooth operation of the gas spring and avoid accidents, for safety reasons, designers not only need to trust the brand, but also consider increasing the safety stroke to ensure the long-term normal operation of nitrogen.
3. Arrangement of Focus
In mold design, the transmission of elastic pressure should be balanced. The layout of the focus should focus on solving balance problems. Usually there are multiple mold gas springs. From the perspective of stamping technology, it is also necessary to consider the balance of stamping pressure, in order to improve the service life of the mold and ensure the quality of the stamped parts.
From the use of the mold gas spring, it can be seen that the gas spring is in direct contact with the parts, and the elastic pressure is transmitted to the working parts of the mold through the designed mold parts such as the top material plate, top material block, edge pressing ring, and wedge block. Is the motion balance of mold working components such as the top material plate related to the arrangement of the force system; On the other hand, the push plate also plays a role in transmitting force to the gas spring. Therefore, in order to avoid the eccentric load of the gas spring, improve the service life of the gas spring of the die, and increase the service life of the die, the design method of the superposition of the center of the gas spring pressure system and the center of the pulse pressure should be adopted. Therefore, in order to avoid the eccentric load of the gas spring, improve the eccentric bearing capacity of the die gas spring, and ensure the service life of the gas spring, the design method that the center of the die gas spring pressure system coincides with the center of the pulse pressure should be adopted.
