Problems solved by technology

[0010] One of the main difficulties in the simulation of the injection molding process is the instantaneous free surface of the molten resin. When the in-mold decoration injection molding integrates processing technologies such as flat printing, thermocompression molding, precision punching and injection molding, the moldable film must be overcome during the injection process. Problems such as positioning, ink scouring, stretching and warping, etc., the application of computer-aided engineering analysis technology can help to understand the cause of the problem, but there are still too many unreasonable applications of commercial computer-aided engineering technology in the injection molding process of in-mold decoration Assumptions
Therefore, the habitual user cannot meet the needs of the user in actual use

Abstract

The invention relates to an engineering analysis method used for in-mold decoration injection molding. The method is divided to molding engineering analysis, grid interface processing and injection engineering analysis, and comprises the following steps: first, establishing a film grid, a molding mould grid and an injection molding grid, importing the film grid and the molding mould grid, and setting a molding parameter for engineering analysis so as to obtain molding analysis information; operating according to the injection molding grid and the molding analysis information to obtain an embedded film grid and an injection resin grid; and importing the embedded film grid and the injection resin grid, and setting an injection parameter for mold flow analysis so as to obtain in-mold decoration analysis information. The engineering analysis method is integrated with a molding analysis program and an injection analysis program, improves the analysis precision of the in-mold decoration injection molding, and shortens the engineering analysis time of the in-mold decoration injection molding, thereby shortening development time of a product and reducing cost.

Description

Technical field: [0001] The invention relates to an analysis method, in particular to an engineering analysis method for in-mold decoration injection molding.
