There are two kinds of product map data in CAD/CAM mold design. One is the part drawing drawn by its own CAD/CAM software, which can be directly loaded for mold design. The other is that the data is designed from external systems. Explain the latter case and talk about another design idea for this situation in Zhongwang 3D.
Importing product data from an external CAD/CAM design system will inevitably lead to data loss. The most direct performance is that we often say that the product has a broken face. In the current Proe, SW, Inventor used in the industry, to do mold design, the broken surface of the product must be repaired to make it a complete entity, in order to carry out the next mold design work. The core algorithm is to cut the cavity of the product by Boolean operation. Zhongwang 3D's conventional idea design is also the same, but Zhongwang 3D's hybrid modeling concept provides us with a completely different design idea.
Here is a case of a camera case to illustrate it. After the product is introduced, some arc faces with three corners are often broken or deformed. As shown in the figure below, this product has a broken face when it is loaded. In Zhongwang 3D, you can not go to the meeting and go directly to the following mold design steps.
According to this model, as long as the product is correctly drafted, even if there is a broken surface, the correct parting line of the product can be obtained.
The product can be divided into upper and lower parts by a parting line. After the product is divided, the part that needs to be removed, such as the core, can be separately output, and the electrode design can be performed when the mold design is not completed. At present, the development cycle of products is getting shorter and shorter, which puts higher requirements on the control of time for mold companies. The customers of the mold company hope that the products can be listed as soon as possible to occupy the market, so the time from design to production is required to be shortened as much as possible. The entire delivery time of the mold company must be greatly reduced in order to be competitive in the market. If the conventional idea is adopted, the electrode of the entire mold enterprise cannot be fully utilized after the mold design is completed. The mold was not removed and the electrode engineers could only wait. This medium mode of Zhongwang 3D can support parallel engineering very well. Make full use of all the resources of the mold company.
Separate the front and rear mold cores of the mold, remove the inserts, and remove the sliders. As long as the part of the removed part is not at the broken surface, the product will not have any effect on these operations. All the materials and the processing of the formwork can be carried out simultaneously.
If you use the conventional design idea, you can only repair the product before you can carry out the following process. If this conventional idea encounters a complicated product, the light repair surface may take several days, which will be a big test for the shorter and shorter die time. By using the 3D hybrid modeling concept in CAD/CAM software, it is possible to bypass the seam surface and smoothly carry out subsequent CAD/CAM design, which can make full use of resources and improve the overall mold design. effectiveness.
