【導(dǎo)讀】越高的要求，2021年，塑料模具在整個模具行業(yè)中所占比例已上升到30%左右，達(dá)到10%以上的較高速度的發(fā)展。國內(nèi)塑料模具市場以注塑模具需求量最大，其中。以一次成型形狀復(fù)雜的精密塑件。本課題就是將塑料蓋作為設(shè)計模型，將注射模。具的相關(guān)知識作為依據(jù)，闡述塑料注射模具的設(shè)計過程。本設(shè)計對塑料蓋進(jìn)行的注塑模設(shè)計，對塑件結(jié)構(gòu)進(jìn)行了工藝分析。計思路，確定了注射成型工藝過程并對各個具體部分進(jìn)行了詳細(xì)的計算和校核。如此設(shè)計出的結(jié)構(gòu)可確保模具工作運(yùn)用可靠，保證了與其他部件的配合。AutoCAD繪制了一套模具裝配圖和零件圖。所有下載了本文的注意：本論文附有CAD圖紙和完整版說明書，凡下載了本。最后，希望此文能夠幫到你！

　　

【正文】 . Autodesk Moldflow MDL) is too Link (Moldflow product series of important data Link tools. Through various products not only can easily Moldflow IGES, Stereo, read presented. the Lithography (STL format) 3D model, but also directly read Parasolid (UG), Pro/E, Ideas, such as CATIA, Solidworks highend CAD software to the latest version of the original files, and other 3D model for software Ansys, such as structural analysis of CAE Nastran, and Patran ABAQUS, and lsdyna, Hyper as the mesh generating webmaster can also pass to MDL for further analysis of AMI. In except to support data model transformation after the traditional functions, but also increased the following new features: (1) to CAD entity driver is the core of grid generation way, (2) ponents (assembly model) and the grid directly import automatic dividing, (3) direct mesh division 3D entity, (4) long and narrow features removal. Autodesk Moldflow CAD Doctor is a powerful tool that can check to model, repair, adjust and simplified entity model or IGES surface model, through bining with the Doctor can MDL, CAD import all the mainstream of 3D CAD/CAM software generation 3D models. The Doctor generate high quality Cad entity or surface model can directly into in order to AMI or AMA construct rapid high quality of the finite element mesh model, to improve the speed of processing in before and effectively improve the accuracy of analysis. 33 Current CAD Doctor has fully support 64bit operating system, users can easily super model of work. The main function of Cad Doctor include: (1) to IGES surface model of automatic repair and suture, (2) of the surface model or geometric structure adjustment of topological relationships, (3) characteristics such as small round, bevel, convex platform, indentation, round hole and characteristics of the automatic recognition and removal, (4) to YinWen surface characteristics of rest respectfully or automatic recognition and removal, Automatic extraction (5) can be used to die (from formwork directly from water or flow structure). Normally, the most mon AMI (MPI) to simulate the process of injections, which get the best gate number and position, reasonable flow system and cooling system, and the cavity dimension, gate dimensions, port size and cooling system, and optimize the size of injection process parameters are optimized. AMI not only can consider to traditional problem analysis, Injection Molding twomaterialinjection were (Over), Gas Injection Molding (Gas), assistant Injection Molding (Co ), Injection Molding Injection pressure and Compression () (), Mucell foamed optical Birefringence analysis (Birefringence), the recent rise of hot runner system also can feed on the dynamic simulation of AMI, also can be analyzed and the reaction of thermosetting Molding materials of electronic chips, AMI widely used in packaging, medical, automotive, aerospace and 3C with plastic packaging etc all related industry. The latest version for AMI, AMI products include the following analysis module. ● AMI/Synergy, it is a front and rear processor, support the MPI series products of all analysis module. ● AMI/Flow and pressure filler can Flow equilibrium analysis, temperature, pressure, clamping force, weld lines, exhaust and process conditions optimization. ● AMI/Cool optimization design, mold cooling system is analyzed in 34 order to realize accurate realization uniform cooling or the minimum size of the product shape cycle. ● AMI/Warp analysis of warping deformation and warpage deformation shapes whether meet the design requirements, and also can analyze product shrinkage. ● AMI/Stress integration of molding structural analysis, thus influence on the overall structure of more accurate evaluation. ● AMI/Fiber glass Fiber strength and stiffness of the product has great influence, through the glass Fiber analysis can assess fiberglass products structure deformation of the MHD effect. ● AMI/on bining process condition optimizing mold cavity dimension design, analysis of the actual shape material shrinkage. ● AMI/Gas optimization design of airway and gasassisted technological condition, ensure the feasibility of Gas assist product design. ● AMI/Co Injection also said that in a sandwich Injection, a core materials into another kind of materials in order to meet the requirements of quality and cost. ● AMI Injection/Compression stress requirements for the optical products such as low CD, plastic lenses and ultrathin product to have the important meaning. ● AMI/MuCell optimization analysis, in order to reduce the physical foaming product, reduce weight because viscosity reduction and improve with clamoing forces, reduce molding cycle, increase product structure. ● AMI Birefringence of transparent plastic/Birefringence, analyzes the residual stress of vision to the influence of optical properties. ● AMI/Reactive Molding Analysis of optimization of plex crosslinking reaction of thermosetting molding process. ● AMI/Microchip Encapsulation analysis, optimizing electronic chip packages analysis of gold of migration and chip drift. 35 ● AMI/Underfill Encapsulation analysis flip chi p packages, can consider to fill the reaction and solder joints. 2. Moldflow filling mold flow mathematical model Moldflow provide three types of grid mesh model of products: (1) the Midplane (neutral face grid) for thin shell product analysis, extraction of intermediate, (2) Fusion (double grid) for thin shell product analysis, will need several days shorten the time between extraction for a few minutes, is the most widely used type of grid. (3) 3D (mesh threedimensional entity ), applicable to all types of products, including thin or thick wall shell. Neuter surface grid and double grid filling mold flow mathematical
