The 3D design of the mold is completed according to the shape of the two-dimensional point paper and the exhaust pipe of the mold to ensure that the wall thickness of the exhaust pipe meets the requirements. According to the 3D data of the No. 3 core box, the design of the outer mold and the No. 3 core box is designed by the assembly design method.
Exhaust pipe casting mold CAM.
According to the casting process requirements and the shape of the mold, the process design of the mold processing is completed, and the tool path of the CNC machine tool is laid and the front and rear processing is completed according to the process design.
3 sand core forming inspection The upper and lower molds are clamped in the computer, and the middle cavity is extracted to generate a three-dimensional model of the sand core obtained by high pressure modeling to verify the quality of the three-dimensional design of the mold. If the sand cores of the complete set of molds are assembled together, the positioning relationship between the complete molds can be verified, the design quality of the complete molds can be verified, and the virtual manufacturing of the castings can be realized.
New technology
CAD/CAM integration and paperless design ideas are used to design and manufacture the mold, and the design and CAM of the exhaust pipe nozzle and parting surface are completed directly in the computer. Research virtual manufacturing technology in mold CAD/CAM application, complete the upper and lower mold clamping with PRO/E software in the computer, and extract the 3D model of the sand core. The visual dynamic analysis technology is used to adjust the airway surface to make the airway 3D surface smooth and smooth, and the matching of the airway port and the combustion chamber is completed by digital technology. It took 6 months to use the original method, and it has not been able to meet the requirements many times. It took only half a month to complete the 3D design with the new method, and only 2 times to meet the requirements.
Using CAM principle and reverse engineering to design the airway wall of the water jacket, using advanced CAD/CAM software to design the mold directly from the 3D data of the product, using the assembly design to design the mold to ensure the design quality of the mold, using advanced The CAD/CAM software completes the 3D design and CAM work of the mold and is at the leading level in China.
Technical level and benefit analysis
At present, major foreign automobile companies have widely used CAD/CAM integration technology to design and manufacture casting molds. China's major automobile factories have introduced CAD/CAM technology since the mid-1980s, mainly used in 2D drawing and CAM technology. In the early 1990s, major domestic automobile factories started to promote the application of CAD/CAM. They have invested a lot of manpower, material resources and financial resources, and purchased corresponding software and hardware equipment. CAD/CAM technology has been widely promoted and applied. We applied the visualization technology to complete the 3D design of the engine air passage, and used the digital technology to complete the matching of the air passage port and the combustion chamber. The CAD/CAM technology was used to complete the 3D design of the engine cylinder head mold, the exhaust tube core box and the mold. The CAM principle and reverse engineering are used to design the air passage wall of the water jacket. The advanced CAD/CAM software is used to design the mold directly from the 3D data of the product in the computer, and the design of the mold is designed by the assembly design to ensure the design quality of the mold. The advanced CAD/CAM software completes the 3D design and CAM work of the mold, which verifies the feasibility of virtual manufacturing and brings the design and manufacture of Dongfeng Motor's product development and casting mold to a new level.
Through the implementation of the project, the CAD/CAM work of the cylinder head and exhaust pipe mold was completed in a short period of time, which accelerated the production preparation of the EQ1030 light-duty vehicle, and solved the urgent need for the EQ491 engine to produce no castings, and the EQ491 engine exhaust pipe. Samples are provided for production line commissioning. Thanks to the new airway design method, CAD/CAM integration technology has shortened the design and manufacturing cycle of the mold by more than half a year, greatly improved the design quality, improved the efficiency of the airway 3D design, and saved a lot of airway trial cutting costs. . Using mold CAD/CAB technology and virtual manufacturing technology can visually display errors in the design on the computer, so that errors in the design can be found and changed in time, and the quality of the product and the one-time debugging of the mold production are guaranteed, saving a lot of Commissioning time and cost.
Idea for further development
By completing the computer-aided design-assisted manufacturing of the casting molds for these two parts, we have accumulated valuable experience in the CAD/CAM of casting molds. For future work, we are ready to further implement the parts directly in the calculation. The 3D design, and the 3D model of the part design the parting line and the parting surface, further complete the 3D design of the mold directly in the computer, and extract the 3D model of the sand core according to the 3D model of the mold, and then obtain the casting. The 3D model is used to verify the quality of the mold design, and finally complete the CNC programming and machining simulation of the mold. Achieve paperless design and manufacture of molds.
That is to realize the application of CAD/CAM integration technology and virtual manufacturing technology in the design and manufacturing process of casting molds. Improve mold design and manufacturing level and quality, accelerate mold design and manufacturing speed, shorten product production preparation cycle, and achieve a leap in mold design and manufacturing quality.
