Abstract
This application relates to the technical field of formwork design, and in particular to a formwork rigidity comparison method. The formwork rigidity comparison method includes the following steps: obtaining the inner distance L of two tie rods located at opposite corners, and The maximum deformation S of the template at the center of the mold loading area; according to the formula K=S / L, the relative deformation coefficient K of the template at the center of the mold loading area is calculated. Through this method, the corresponding mold clamping force, template size, mold frame parameters, and template deformation values required for different types of products can be quantified using unified index data for different models, without the need for the designer's experience. By analogy design, the rigidity deviation of the template of the injection molding machine designed in this way is small, and the problem of weak or strong template rigidity caused by the lack of unified index guidance is avoided.
Description
technical field [0001] The present application relates to the technical field of template design, in particular to a template rigidity comparison method. Background technique [0002] At present, in the formwork design process, the analogy design method and empirical data cannot scientifically and accurately measure the performance of the formwork and guide the design. The mold clamping force, template size, and mold base parameters corresponding to different models are not the same. At the same time, the requirements for the template deformation value required for the production of different types of products are also different. There is no unified index data for quantitative guidance during template design. Carry out analog design based on the experience of the designer. For example, in the design, only by referring to the deformation data of the original similar template to increase or decrease the deformation value for analysis and optimization. If the clamping force, te...
