The Analysis of Core Shift in Injection Mold and its Optimization Based on AMI

Abstract:

Core shift is the phenomenon that the core will be shifted under the injection pressure during its molding process. Excessive core shift will bring variation in frozen-crust thickness which will lead to the buckling deformation of products and lower their structural performance. This paper takes the shell of U-disk as an example and analyzes the reasons of core shift in the injection mould designing with AMI, and its analyzed findings can be used for mould designing to shorten the developing period of products and decrease the cost of products and increase their economic benefit.
