Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] see figure 1 As shown, a kind of mold optimal design method provided by the present invention comprises the following steps:

[0030] S100, establishing an analysis model of the product to be injected;

[0031] S200, establishing a preset pouring scheme;

[0032] S300, Moldflow database selects injection molding materials for fluidity analysis;

[0033] Among them, when there is no identical injection molding material in the Moldflow database, the injection molding material with the closest shear viscosity is selected.

[0034] For the above mold optimization design metho...

Abstract

The invention provides a mould optimization design method. The method comprises the following steps of building an analysis model of a product to be subjected to injection molding; establishing a preset pouring scheme; and selecting injection molding materials to perform flowability analysis by a Moldflow database, wherein the same injection molding materials do not exist in the Moldflow database,the injection molding materials most similar in shear viscosity are selected. According to the mould optimization design method, when the same injection molding materials do not exist in the Moldflowdatabase, the injection molding materials most similar in shear viscosity are selected; and the flowability analysis is performed based on the materials most similar in shear viscosity, so that a flowability analysis result can be close to an actual injection molding result, the accuracy of optimization design is improved, hidden dangers possibly occurring in a mould test process can be eliminated, the mould test cost is reduced, and the product development efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a mold optimization design method. Background technique [0002] With the development of the modern mold industry, the application of plastic simulation computer analysis software - Moldflow software is becoming more and more common. In order to better play the role of Moldflow software, designers should try to choose the same material as the actual material in the Moldflow software material library. CAE (Computer Aided Engineering, Computer Aided Engineering) mold flow analysis for the materials, otherwise the obtained results will be quite different from the actual ones, which will affect the entire new product development cycle. However, since new materials are constantly being used in injection molding products, and Moldflow software cannot cover new materials in time, how to choose a material similar to the new material used for Moldflow flow simulation analysis to...
