摘  要
　　　本论文主要介绍注射模模的设计过程，通过对塑件产品的分析了解，初选注射成型机的型号和规格，确定模具的总体结构为双分型面注射模，点浇口进料，及点浇口自动推出机构。设计模具的浇注系统、排气系统、冷却装置、成形零件等，选定标准模架和结构零部件，最后校核计算；并根据所选的模具结构绘制出主要的零件图如定模固定板模板、支承块、推杆、导柱、导套等。利用AUTOCAD绘制出模具的装配图，并应用CAXA制造工程师软件生成了模具型腔，然后进行了模拟加工仿真。

The design and processing simulation of the toy airplane outer shell injecting die
Abstract
　　　This thesis mainly the introduction inject the design process of mold and pass analysis understanding to the Su piece product, the primary election injects the model number and specification of modeling the machine, the total structure of the assurance molding tool for double cent type the noodles inject a mold and order to sprinkle to enter to anticipate, and order to sprinkle to automatically release organization. Design a sprinkling of molding tool to note the system, row spirit system, cool off device and take shape spare parts etc., make selection standard mold and structure zero partses, finally the school calculate calculate; Also draw a main spare parts diagram according  to the molding tool structure chosen such as certainly the mold fixed plank template, pay to accept a piece, push a pole, lead pillar and lead a set of etc.Make use of AUTOCAD to draw an assemble diagram of molding tool, and apply CAXA the manufacturing engineer's software is born molding tool type chamber, then carried on emulation to process to imitate really.
