Original Abstract Submitted
An optimization method for a layering scheme of multilayer injection molding, including: solving a heat transfer equation by using a finite difference method to obtain a cooling time for injection of each layer under different layering schemes, and obtaining a relationship model of a cooling time of a single layer and a layering scheme by fitting; and finally, with an objective of minimizing cooling times of all injection layers and a constraint condition of a total thickness of a product, optimizing a particular layering scheme by using a Lagrange multiplier method. Through optimization by the method, an optimized layering scheme can be obtained, allowing for an effectively shortened injection molding cycle, a reduced production cost, and improved product quality.
