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
