Introduction to buckling of injection molding die column

The buckling of a mold column in injection molding refers to the failure of the column due to the force applied to the top of the column, which cannot be explained solely by the bending or compression stress. These cylindrical or prismatic mold accessories have support columns, ejector pins, straight push tubes, diagonal ejector rods, etc.

In the mechanical calculation, the theory is realized through the accumulation of many destructive experiments, so the preconditions of the experiment must be fully understood before the application of the calculation formula. At present, the use of Excel and other computing software can be very convenient to draw and chart, but the first-class mold designers must understand how the calculation formula is derived and fully understand its background.

Many experiments have been done to some extent to understand the mechanical conditions under which the buckling of injection molding mold column occurs. Buckling can be predicted by mechanical calculations of materials. Then, by mechanical calculation of buckling, the appropriate strut thickness and the risk of buckling of ejector pins can be predicted.

The longer the length of injection molding column, the more significant the buckling will be. In addition, whether the end of the column is fixed or free to move can also change the way the buckling occurs. The mission of Fanstar is to master the core technology of injection molding production, to communicate and analyze the technology before the production of injection molding with customers from the production needs of finished products, so that the injection mold delivery time is short, the service life is long, the mass production is fast and the finished product quality is excellent!
