Description

technical field [0001] The invention belongs to the technical field of the die-casting mold industry, and relates to a pouring parametric design system and method for a die-casting mold. Background technique [0002] At present, most die-casting companies use CAXA, AutoCAD, CATIA, UG and other common CAD software to draw 2D sketches manually in the process of runner design, extend the mold opening direction for directional stretching, and manually modify the corners of the details after the runner is formed. Due to the complexity of the runner structure, the traditional 2D CAD design method cannot accurately and intuitively express the information of each module of the runner. Although the large-scale general-purpose 3D CAD software is powerful, it has problems such as low specificity, forcing users to work on die-casting molds. In the flow channel design process, approximate processing and a large number of manual repeated operations are used, which seriously affect the des...

AI Technical Summary

Problems solved by technology

[0003] I. The implementation process of each module of the flow channel requires a large number of repeated operations by the designer, and the efficiency is low;

[0004] II. The design dominated by geometric features such as traditional points, lines, and surfaces has little distinction, and the design methods of different designers cannot be unified, and the expression of design information is scattered and incomplete;

[0005] III. It is not conducive to the subsequent expansion design of the die-casting runner design, such as the establishment of the runner analysis model and further optimization and improvement, etc.
