Embodiment Construction

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0040] The simulation analysis of the present invention is achieved based on the existing injection molding simulation simulation analysis tool MoldFlow (hereinafter referred to as MoldFlow), such as figure 1 As shown, the method of improving the reverse deformation accuracy of the injection molding product is:

[0041] 1. MoldFlow analysis is performed by the product of the same material and the similar structure, and the actual deformation result is compared to the experimental factor K.

[0042] For example, as follows:

[0043] Such as figure 2 with image 3 As shown, label 2 is the theoretical product model, 1 is the product model of MoldFlow simulation, through the MoldFlow regular analysis, the maximum deformation amount is 0.5, but after the actual production, the actual product is labeled 3, the maximum The amount of deformation is 1, that is, ...

Abstract

The invention provides a method for improving the anti-deformation accuracy of an injection molding product, and a system, and belongs to the technical field of injection molding. The method comprises the following steps of conducting injection molding simulation analysis on a product, and obtaining the theoretical deformation of the product; obtaining the actual deformation of the product, and comparing the theoretical deformation with the actual deformation to obtain an empirical coefficient K; based on the empirical coefficient K, modifying simulation model parameters, so that the theoretical deformation of a analysis result of a simulation model is the same as or similar to the actual deformation; and based on the modified model parameters, deriving a reversible deformation model opposite to an analysis model. The method for improving the anti-deformation accuracy of the injection molding product, and the system provided by the invention have the beneficial effects that the precision of simulation analysis is improved, and rapid and accurate conversion from theory to reality is easier to realize.

Description

Technical field [0001] The present invention relates to an injection molding product manufacturing technique, and more particularly to a method and system for improving the reflexive accuracy of injection molded products. Background technique [0002] As consumers have more and more manufacturing products in fields of products and functional requirements for automobiles, medical, industrial industries, requiring a single product to be smaller and smaller, requiring a single product. The deformation is also getting smaller and smaller, with the rapid development of the entire industry, the manufacturing capacity of the company is also getting higher and higher. [0003] Factors affecting product prediction accuracy include machining errors, material errors, measurement errors, and process fluctuations. For these factors, it is necessary to make a mold, and the size tolerance of the product is measured by blue scanning or 3D coordinates. The modification of the RPS (positioning poi...
