Mold design and development of three-dimensional graphics generation system


Three-dimensional mold assembly Graphics 3.1 System architecture (see Figure 1 below) 3.2 feature implementation of database management 3.2.1 mold mold injection mold the national standards are divided into The structure of small and medium mold sub-models by species, namely, the basic type 4, 9 variants to be mold, mold base plate moving shoulder, no shoulder division, increased 13 varieties, a total of 26 mold species . The template NO. 6 Total 39 35 a J parlous Midship understand. & Delete. Die CAD / CAE / CAM series for each width of the size of the main parameters, together with a group size of each element, composed of 12 series of dimensions. Accordance with the same species, with the series of the thickness of the selected template A,mulberry laukku, B, and plate height c of each series by the specifications again. In addition, the mold used in all GB4169.1-11-84 Therefore, the standard mold of a large amount of data. However, the standard mold injection mold parts and structure of a certain law, it is appropriate using parameterized main parameters extracted from mold, you can create a unified database to achieve the standard mold mold data system call, which can be more good land-aided design staff to complete the selection and design of mold, to avoid duplication of low-level. Main parameter is the mold in accordance with national standard method for marking plastic mold frames are summarized, with a certain degree of universality. GB planes in the plastic mold labeling method is: a series of specifications for a variety of derivative forms, such as pins and bushings and installed a 15 A1-180L a Z2, standard mold of the selection is based on the above four aspects,tory burch uk, which is given by the user 4 a selection of parameters. (1) mold species. A basic standard mold base and derived type 4 9, a total of 13 species. In the example of the A1 type. (2) Mold size series. This parameter determines the width and length of the template. Parameters such as the case 180L, 180 of which is the width, L is the length. (3) mold specifications. Mainly to the action, and set the template thickness and pad thickness. Parameters such as the case l5, is the use of section l5 of the family line thickness value. (4) guide pins and bushings installed form. Are loaded, all 3 types of anti-installed. Z2 parameters such as the example that suits. Mold base to build, the standard mold of the data size required to create two tables. The size of mold can vary, so you can size the diagram as a field in the database code to build Access databases. 3.2.2 Selection and design of mold in the mold MBCAD system option is selected in the standard mold base for mold or mold present in the non-standard library mold. Mold is the first choice of algorithms to calculate the cavity theory placement in the template identified mold after the side parallel to the external side of the rectangle,mulberry norge, and then some experience under constant cavity layout to figure out all the mold cavity share of shelf results. The selection algorithm flow shown in Figure 2. 3.2.3 Rendering the development environment in the ARX ARX application program 36 is called NO6 total 39 (ARXapplication). ARX ​​application is no longer a separate process, but on a DLL (dynamic link library), it began to share AutoCAD flow chart in Figure 2 mold select the address space to directly use AutoCAD's core code, direct access to AutoCAD database ,mulberry københavn, the core graphics system,ed hardy outlet, and geometric modeling, real-time extension during operation of classes and functions with AutoCAD. Use of external data in the database as drawing parameters through ODBC interface, using MFC CRecordset class to read in the mold in the database parameters, rendering parameters of the AutoCAD drawing file. Three-dimensional graphics drawing mold shown in Figure 3. The following are dynamic model base plate part of three-dimensional graphics drawing code: / / dynamic model base plate to draw three-dimensional graphics voidCMjdlg:: drawd0ngmzb0 {AcGePoint2dArraypt2d1; pt2d1. setLogicalLengthf4); pt2dl [O1. set (-m_xlbset.Ill--H1 / 2,-m_xlbset.Ill--tJ2);
