模具是生产各种工业产品的重要工艺装备，随着塑料工业的迅速发展，以及塑料制品在各个工业部门的推广应用，产品生对模具的要求也越来越高，传统的模具设计方法已无法适应当今的要求。与传统的模具设计相比，计算机辅助设计论（CAD）技术无论是在提高生产率、保证产品质量方面，还是在降低成本、减轻劳动强度方面，都具有极大的优越性。

Abstract
 
Die is an important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in various industrial sectors, the requirements of the products on the moulds are also getting higher and higher, and traditional mould design methods can no longer be adapted. Today's request. Compared with the traditional mold design, computer-aided design (CAD) technology has great advantages in terms of improving productivity, ensuring product quality, reducing costs, and reducing labor intensity.
Excavators are used for excavation, loading and unloading, lifting, piling, rammed earth, crushing, demolition and other operations in construction and emergency rescue operations. The control part of the excavator is placed in the control box. The rotation, excavation and loading and unloading operations are accomplished by controlling the front handle of the control box. The traditional excavator control box lacks intelligent control function settings and cannot meet the upgrading requirements of excavators working in hazardous environments. Manipulating the cabinet box requires changing its form according to the needs of intelligent control. This topic carries out the design and simulation of the injection mold according to the requirements of the excavator's intelligent operation box.
