Embodiment 1

[0042] A method for collecting the accuracy of product shrinkage rate provided by an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0043] Step S1: Establish a space coordinate system of the product, and select a preset number in each space coordinate direction to represent the size of the outer contour of the product.

[0044] In the embodiment of the present invention, selecting a preset number of sizes representing the outer contour of the product in each space coordinate direction includes: avoiding the warping position of the product in each space coordinate direction, and selecting at least three dimensions representing the outer contour of the product. The size of the outline is just an example and not limited thereto. In practical applications, the corresponding preset number is selected according to actual needs to represent the size of the outer outline of the product.

[0045] Step S2: According to the spatial coordina...

Embodiment 2

[0064] An embodiment of the present invention provides a collection system for the accuracy of product shrinkage, such as figure 2 shown, including:

[0065] The establishment module 1 of the coordinate system is used to establish the spatial coordinate system of the product, and selects a preset number to represent the size of the outer contour of the product in each spatial coordinate direction; this module executes the method described in step S1 in Embodiment 1, I won't repeat them here.

[0066] The mold cavity size obtaining module 2 is used to obtain the product mold cavity size according to the size of the outer contour; this module executes the method described in step S2 in Embodiment 1, which will not be repeated here.

[0067] The actual size acquisition module 3 is used to actually measure and acquire the actual size of the product under preset conditions; this module executes the method described in step S3 in Embodiment 1, which will not be repeated here.

Abstract

The invention provides a method and system for collecting the shrinkage rate and the accuracy of product, and the method comprises the steps: building a space coordinate system of a product, and selecting a preset number of sizes representing the outer contour of the product in each space coordinate direction; according to the size of the outer contour, obtaining the size of a product mold cavity; under a preset condition, obtaining the actual size of the product through actual measurement; calculating the actual shrinkage rate of the product according to the size of a product mold cavity and the actual size of the product; determining the theoretical shrinkage rate of a product by conducting simulation analysis on actual mold testing process parameters; calculating the accuracy of the theoretical analysis shrinkage rate of the product according to the actual shrinkage rate of the product and the theoretical shrinkage rate of the product; and collecting and archiving the accuracy of the product theoretical analysis shrinkage rate according to a preset priority. The method for determining the accuracy of the product shrinkage rate is determined and the shrinkage rate data is collected, so that the accuracy of the product mold shrinkage rate is improved, and the product development cycle and development cost are reduced.

Description

technical field [0001] The invention relates to the technical field of mold shrinkage rate, in particular to a method and system for collecting the accuracy rate of product shrinkage rate. Background technique [0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. When making plastic parts, it is necessary to test the plastic raw materials. Due to the various components of plastic products, the presented The nature of the product is also relatively broad. In the performance evaluation of plastic products, the product shrinkage accuracy test is an important indicator. Before the mold opening design, the shrinkage accuracy of the product needs to be collected. For products with high precision requirements, the accuracy of shrinkage accuracy collection is particularly important. The collection of shrinkage accuracy will directly affect the development cycle and cost invest...
