落地风扇底座注塑模具的设计(含CAD图,PROE三维图)

落地风扇底座注塑模具的设计(含CAD图,PROE三维图)(设计说明书13000字,CAD图纸9张,PROE三维图,工艺卡片)
摘要：塑料工业是当今世界上增长最快的工业门类之一，而注塑模具是其中发展较快的种类。因此，研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。
本设计介绍了的落地扇底座注射成型的基本过程，对注塑产品提出了基本的设计原则；详细介绍了塑件成型工艺设计，注射机的选择，浇注系统的的设计，成型零件的结构设计，脱模推出机构的设计，冷却系统的设计的过程。并对标准模架的选择也作了相应的介绍。通过本次设计，使我掌握了注塑模具设计的全过程，同时也提高了运用CAD绘制复杂装配图的能力。

Design of floor fan base of injection mold
Abstract: the plastic industry is one of the fastest growth in today's world, and the injection mold is one of the types of rapid development. Therefore, research of injection mold of plastic production process and improve product quality to have the very big significance.
This design introduces the basic process of injection molding of the fan base, put forward the basic design principles of injection molding product with plastic molding process; design isintroduced, the choice of injection machine, the design of gating system, the structure designof molding parts, mold release mechanism design, cooling system design process. And the choice of the standard mould were introduced also. Through this design, I mastered the whole process of the injection mold design, but also improve the ability to use CAD to draw the assembly drawing of complex.

Keywords: plastic injection mold; mold structure
