Method, system and device for optimizing mould matrix size, and storage medium

Abstract

The invention relates to a method, a system and a device for optimizing a mould matrix size, and a storage medium. The method for optimizing the mould matrix size comprises the following steps that: obtaining the practical size parameter of a mould matrix and the contact force of the mould matrix and blank in a stamping process; and according to the practical size parameter and the contact force,obtaining the simulation size parameters of a simulation mould, screening the simulation size parameter which conforms to the preset condition, and outputting the simulation size parameter as an optimization result. By use of the embodiment of the invention, under a situation that the deformation amount of the mould matrix meets a constraint condition, the mould matrix size is optimized, so that the volume of the mould matrix is minimum, the weight of the mould matrix is lowered, meanwhile, the rigidity of the mould is improved through the optimization algorithm, the mould matrix size is optimized under a working condition that a topological structure is constant, and light weight is realized.

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a method, system, device and storage medium for optimizing the size of a mold matrix. Background technique [0002] When optimizing the mold in the prior art, the force of the mold is used as the boundary condition to calculate the deformation of the mold; it performs topology optimization on the matrix structure of the mold based on the variable density method. It can improve the structural rigidity of the mold, make the quality of the stamping parts more stable, and at the same time make the mold lighter. [0003] However, the materials used in each area of ​​the mold manufactured by this process are different, so as to reduce the deformation of the mold during the use of the mold, but the mold manufactured in this way is expensive to manufacture and the manufacturing process is difficult, and various manufacturers cannot pass it. In the case of optimizing the...

[0003] However, the materials used in each area of ​​the mold manufactured by this process are different, so as to reduce the deformation of the mold during the use of the mold, but the mold manufactured in this way is expensive to manufacture and the manufacturing process is difficult, and various manufacturers cannot pass it. In the case of optimizing the mold by the variable density method, thickening the wall thickness of the mold is used to reduce the deformation of the mold during the stamping process, but thickening the wall thickness of the mold will make the volume and quality of the mold very heavy, which is not only difficult transfer and is very material intensive
