The invention relates to the field of mold design, and concretely relates to an optimization method for a compression molding die of an automobile hallstand. The optimization method comprises the following steps: performing process numerical simulation on a hallstand compression molding process by using a structure analysis nonlinear finite element program to obtain convex-concave die node force information; constructing topological optimization boundary conditions of a punch-die structure by using a load mapping method; using finite element structure analysis and optimization software to carry out punch-die structure topological optimization iterative solution; and according to the final topography of topological optimization of the punch-die structure, using three-dimensional software for improving the structure of the punch-die. On the premise that the structural rigidity and strength of the die are met, the weight of the die is greatly reduced, and the production cost is reduced.
Description
technical field [0001] The invention relates to the field of mold design, in particular to an optimization method for a molding mold of an automobile coat rack. Background technique [0002] With the growth of the economy, my country's auto industry is developing rapidly, and the number of cars is increasing year by year. People are paying more and more attention to the quality of car interiors while pursuing beautiful body shapes and surging power. Car interiors have become a measure of car grades. an important factor. After decades of rapid development, automotive interior parts have gradually developed from providing a basic driving and riding environment for drivers and passengers to a high value-added product that combines design aesthetics, ergonomics and humanization. The development of automobile interior has become an important content second only to the development of automobile body. [0003] As the main molding process of automotive interior products, compressio...
