Embodiment 1

[0037] see figure 1 As shown, the embodiment of the present application provides a template rigidity comparison method, comprising the following steps:

[0038] Step 100, obtain the inner distance L of the two tie rods located at the opposite corners, and the maximum deformation S of the template in the center of the mold loading area under the clamped and locked state;

[0039] Step 200, according to the formula K=S / L, calculate the relative deformation coefficient K of the formwork at the center of the mold loading area.

[0040] Note here that regarding the meaning of the above acquisition, the acquisition of L can be obtained by actual measurement, or calculated according to the model parameters, etc., and the acquisition of the maximum deformation S can be obtained through CAE, that is, computer-aided engineering design. Obtained by engineering analysis, it can also be measured by deformation measuring instrument or measuring sensor, etc.

[0041] Through this method, t...

Abstract

The invention relates to the technical field of template design, in particular to a template rigidity comparison method and a forming die. The template rigidity comparison method comprises the following steps that the inner side distance L of two pull rods located at the opposite corner positions and maximum deformation S of a template in the center of the die loading area in the die assembly andlocking state are obtained; and according to the formula K=S / L, the relative deformation coefficient K of the template in the center of the die loading area is calculated. Through the method, for dieclamping force, the template size and die frame parameters corresponding to different machine types and the template deformation value needed for production of different types of products, uniform index data can be adopted for quantization, analogy design according to experience of designers is not needed, accordingly, a designed injection molding machine template is low in rigidity deviation, andthe problem that since no uniform index for instruction exists, the template rigidity is weak or strong is solved.

Description

technical field [0001] The present application relates to the technical field of formwork design, in particular to a formwork rigidity comparison method and a molding die. 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 ...
