B, measurement point is imported inside software and the contrast of 3D product, point inside Survey Software PC-DMIS or visal DMIS by igs file point data importing UG software inside, contrast with original normal data, each point has a deviation and bias direction vector with the model of standard; Accurate data are initial data of product, and the coordinate of any point can draw from product initial data;
Draw deviation size DT and the bias vector Di of counter-bonification after C, contrast, Dj, Dk, the deviation size DT needing contrast, bias vector Di, the name of Dj, Dk and each point is input in TXT file, and the form of TXT file is as follows:
PT, DT, Di,Dj,Dk,
1. PT1 , 0.052, 0.707 , 0.707,0
2. PT2, -0.031, 0.5000, 0.866,0
3. ----；
DT is inclined extent, is the distance of measurement point and standard point; DI, DJ, DK: the direction being space;
D, by DT, Di, Dj, Dk and
diecontrast, draw the spatial point after compensation, containing DT, Di, Dj, the TXT file of Dk is input in die 3D file, then the die of the point of input and standard is contrasted, and the point of input is passed through Di, Dj, Dk projects on die entity, carries out the anti-benefit of a DT, finally all these points is set up in 3D model;
E, compensate point make complementary area, existing face carry out substitute draw compensating body; The point set up in 3D model is presented at inside UG file, starts to do complementary area, by qualified point, required face is set up, and draws anti-benefit face, more original face is replaced to the anti-benefit face of needs, draws anti-complement;
Draw in face of anti-benefit, due to the needs of product or measurement, delete alter a great deal suddenly do not conform to lattice point.
F, obtain the high injection-molding surfaces of precision by compensating body, anti-complement just can be processed, the die processed by anti-complement, and carrying out injection moulding according to identical technique, obtain the working of plastics that precision is high, geometric compensation is complete.
The tolerance of injection-molding surfaces, comprises controlling dimension, profile tolerance, circularity, position degree.
Compared with prior art, the present invention has following beneficial effect:
The present invention calculates personnel and changes computer calculate into, saves the efficiency that personnel calculate.The error rate that minimizing personnel calculate.Ensure the present situation of product, ensure that product is consistent with drawing.To profile tolerance, position degree, circularity can be precisely controlled.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As illustrated in figs. 2-7, the method for automation geometric compensation mould, its step is as follows:
A, product point are measured, on model by inside UG by looking unfamiliar into dot generation measurement point, the quantity determining a little according to the complexity in face and the structure in face; As the circle of an above-mentioned D65, generate 9 layers of point, every layer of 120 point, need counting as 9*120=1080 point of measurement.
B, measurement point is imported inside software and the contrast of 3D product, point inside Survey Software PC-DMIS or visal DMIS by igs file point data importing UG software inside, contrast with original normal data, each point has a deviation and bias direction vector with the model of standard; Accurate data are initial data of product, and the coordinate of any point can draw from product initial data;
Draw deviation size DT and the bias vector Di of counter-bonification after C, contrast, Dj, Dk, the deviation size DT needing contrast, bias vector Di, the name of Dj, Dk and each point is input in TXT file, and the form of TXT file is as follows:
PT, DT, Di,Dj,Dk,
1、 PT1 , 0.052, 0.707 , 0.707,0
2、 PT2, -0.031, 0.5000, 0.866,0
3、 ----；
DT is inclined extent, is the distance of measurement point and standard point; DI, DJ, DK: the direction being space;
D, by DT, Di, Dj, Dk and
diecontrast, draw the spatial point after compensation, containing DT, Di, Dj, the TXT file of Dk is input in die 3D file, then the die of the point of input and standard is contrasted, and the point of input is passed through Di, Dj, Dk projects on die entity, carries out the anti-benefit of a DT, finally all these points is set up in 3D model; Such as, the value that PT1 point obtains from TXT file is above 0.052, on standard die, on the direction of Di, Dj, Dk, so draw the counter-bonification point of a difference-0.052.
E, compensate point make complementary area, existing face carry out substitute draw compensating body; The point set up in 3D model is presented at inside UG file, starts to do complementary area, by qualified point, required face is set up, and draws anti-benefit face, more original face is replaced to the anti-benefit face of needs, draws anti-complement;
Draw in face of anti-benefit, due to the needs of product or measurement, delete alter a great deal suddenly do not conform to lattice point.
F, obtain the high injection-molding surfaces of precision by compensating body, anti-complement just can be processed, the die processed by anti-complement, and carrying out injection moulding according to identical technique, obtain the working of plastics that precision is high, geometric compensation is complete.
The tolerance of injection-molding surfaces, comprises controlling dimension, profile tolerance, circularity, position degree.
The present invention calculates personnel and changes computer calculate into, saves the efficiency that personnel calculate.The error rate that minimizing personnel calculate.Ensure the present situation of product, ensure that product is consistent with drawing.To profile tolerance, position degree, circularity can be precisely controlled.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
