The Meaning Of The Shape Of The EPS Mold To The Deformation

The meaning of the shape of the mold of the EPS mold to deformation The meaning of the shape of the mold of the EPS mold The meaning of the shape of the mold of the EPS mold The meaning of the shape of the mold of the EPS mold to the deformation For a symmetrical mold, the cavity can be considered according to the cavity size, external size and height The tendency to deform. When the wall of the mold is thin and the height is small, it is easier to quench through. At this time, it is possible that the tissue stress plays a leading role. Therefore, the cavity often tends to swell. On the contrary, if the wall thickness and height are large, it is not easy to harden. At this time, thermal stress may play a leading role. Therefore, the cavity often tends to shrink. The deformation of asymmetrical molds is also the result of the combined effects of thermal stress and tissue stress. When the mold shape cannot be changed, in order to reduce the deformation, some other measures can be taken. The general consideration of these measures is to improve the cooling conditions so that each part can be cooled uniformly; in addition, various compulsory measures can also be assisted to limit the quenching deformation of the parts.
