摘要
这次设计的课题是针对一个塑料制成的储物箱,通过三维软件UG、等软件,对注塑零件盖进行3D软件建模,另外,在此基础上,设计人员还对模具的成型结构进行了设计,并绘制出相关的装配图、零件图。在结构设计过程中,经过方案对比,选定采用了一模一腔的设计。本次设计的模具具有工作稳定、结构紧凑、在冷却方面我们采用了随形冷却管道,因为随形的冷却管道具形状复杂,普通的机加工机床无法加工,所以我们采用了3D金属打印的技术来进行制造模具的成型零件等多种特点,最后除了模具结构的设计外,选择了XS-ZY-2000型号的注塑成型机,还对模具的进行了分型面、型腔数目、直接浇注系统、脱模机构、冷却系统等进行了详细的设计。
本次设计主要根据任务书所给的注塑零件盖来进行模具的设计,自主选择的研究产品是储物箱,先利用UG对储物箱进行3D建模,然后根据相应的参数对应选择注射机的型号,并对塑料制品的模架结构进行了设计,对模具参数进行校核,完成了浇注系统和型腔排布的设计,同时还完成了装配图和零件图的设计。在检验过程中需要仔细核对细节,避免发生模具设计不合理、零件干涉等错误的发生。

Abstract
This design is aimed at a plastic storage rubber box, through three-dimensional software UG, and other software, the injection parts cover is modeled by three-dimensional software. On this basis, the designer also designs the forming structure of the mould, and draws the relevant assembly drawings and parts drawings. In the process of structural design, the design of one mold and one cavity is selected through the comparison of schemes. The design of the die has stable work, compact structure, in cooling we used conformal cooling pipe, because the shape of the conformal cooling pipe is complex, ordinary machine tools can not be processed, so we used 3D metal printing technology to manufacture mold parts and other characteristics. Finally, in addition to the design of the die structure, we chose XS-ZY-2000. The parting surface, number of cavity, direct pouring system, demoulding mechanism and cooling system of the injection moulding machine were also designed in detail.
This design mainly carries on the mold design according to the injection part cover given in the task book. The independent choice research product is the storage rubber box. Firstly, the storage rubber box is modeled in 3D by UG. Then, according to the corresponding parameters, the injection machine model is selected. The mold frame structure of the plastic product is designed, the mold parameters are checked, and the casting system and the cavity layout are completed. At the same time, the design of assembly drawing and part drawing has been completed. In the process of inspection, it is necessary to check the details carefully so as to avoid the errors such as unreasonable die design and interference of parts.
Key words: cheese device; die design; CAD drawing two-dimensional map; UG drawing three-dimensional map.
