圆筒塑料注射模具设计(3d)

圆筒塑料注射模具设计
摘  要
本次毕业设计的课题为圆筒件的注射成型模具设计，主要从塑件材料特性、成型性能及塑件的形状、型腔结构等多角度详细分析了塑件注塑加工工艺性。在模具设计前必须对工件进行全面分析，然后合理确定工件的冲压成形工艺方案，以获得高精度、高效率、长寿命的模具及最佳的技术经济效益。

经过计算分析完成该模具的主要设计计算，凸模、凹模工作部分的设计，主要零部件的结构设计，选择合适的模具材料。
初步选择注塑机的型号和规格，对浇注系统、成型零部件、导向及定位机构、脱模机构、冷却系统、模架各部件零件都进行了相关的计算和选择。最后，在参照塑件的体积、重量等参数后对注塑机的相关主要参数进行校核，以判断所选的注塑机能否满足注塑要求。

Abstract
The graduation design subject to cover the injection molding design, mainly from the plastic material characteristics, forming performance and plastic parts, die-cavity structure is analyzed in detail from multiple perspectives, such as plastic injection molding process technology. Because there is no batch production requirements, and small parts, simple structure, a mold piece of the means of production. To be in the mold design to conduct a comprehensive analysis of the workpiece, and then to determine a reasonable job of stamping technology to commit crimes in order to obtain high precision and high efficiency, long life of the mold and the best cost-effectiveness of technology.

After completion of the calculation and analysis of the main design tool, the punch, die part of the design work, the main components of the structural design, choose a suitable mold material.Preliminary selection of type and specification, injection molded parts structure analysis and production mode, appropriate USES double type structure, gating system, forming parts, orientation and positioning and demoulding mechanism, cooling system, formwork components parts are made of calculation and choice.

Key words  Injection molding; Cylinder injection; Injection molding machine
