本次设计采用UG进行绘制，UG的特点 是由CAD/CAM/CAE三大系统紧密集成。用户在使用UG强大的实体造型、曲面造型、虚拟装配及创建工程图等功能时，可以使用CAE模块进行有限元分析、运动学分析和仿真模拟，以提高设计的可靠性；根据建立起的三维模型，还可由CAE模块直接生成数控代码，用于产品加工。 灵活性的建模方式。采用复合建模技术，将实体建模、曲面建模、线框建模、显示几何建模及参数化建模融为一体。本次设计的塑料骨架通过注射模具进行生产，注射模具是指在注射机的加热料筒内，塑料受热熔融，受螺杆或柱塞推动，经喷嘴和模具的浇注系统进入模具型腔，塑料在型腔内硬化定型。设计成型零部件时，根据塑件需求，确定分型面及型腔布局，选择合适的脱模方式。为使得塑件可以一次成型，本次设计还采用了侧向分抽芯机构。

This design is drawn by UG, which is characterized by the close integration of CAD / CAM / CAE. When using the powerful solid modeling, surface modeling, virtual assembly and engineering drawing creation functions of UG, users can use CAE module for finite element analysis, kinematics analysis and simulation, so as to improve the reliability of design; According to the established three-dimensional model, the numerical control code can also be directly generated by CAE module for product processing. Flexible modeling method. Composite modeling technology is adopted to integrate solid modeling, surface modeling, wireframe modeling, display geometry modeling and parametric modeling. The plastic skeleton of this design is produced by injection mold. The injection mold refers to that in the heating barrel of the injection machine, the plastic is heated and melted, pushed by the screw or plunger, enters the mold cavity through the nozzle and the pouring system of the mold, and the plastic is hardened and shaped in the mold cavity. When designing molded parts, determine the parting surface and cavity layout according to the requirements of plastic parts, and select the appropriate demoulding method. In order to make the plastic parts can be formed at one time, the lateral split core pulling mechanism is also adopted in this design.

Composite modeling technology is used to integrate solid modeling, surface modeling, wireframe modeling, display geometry modeling and parametric modeling. The plastic skeleton designed this time is produced by the injection mold, which means that in the heating cylinder of the injection machine, the plastic is heated and melted, pushed by the screw or plunger, enters the mold cavity through the nozzle and the pouring system of the mold, and the plastic is hardened and set in the mold cavity. When designing molding parts, according to the demand of plastic parts, determine the parting surface and cavity layout, and choose the appropriate demoulding method. In order to make the plastic parts can be molded at one time, the lateral core-pulling mechanism is also adopted in this design.
