The design of handset of a telephone handset injecting mould and simulation processing whit the cavity
Abstract: In order to complete the telephone handset mold design, this article has analyzed the telephone handset's craft characteristic and the technological requirement, and explained the mold principle of work.
In the injection mold, divides the profile the design the immediate influence mold's complex degree and the production cost, and has the influence to the product quality. Compared with elaborated the telephone handset mold to divide the profile in detail the design consideration factor, through to the telephone handset's structure and the technological analysis. And used raw material analysis from the work piece to obtain, to discuss the telephone receiver's injection molding craft, has carried on the die space and the core size computation and the strength calculation. According to mold's workability and the plastic formation's technological request, has carried on system's elaboration to the injection molding plastic parts structural design's technological structural design main point. Elaborated molds die space arrangement, to divide the profile choice, the gating system, the formation spare part, to go against with the resetting device and cooling system's design feature, the success has realized mold's formation.
According to the injection mold components structural design's result, to its processing process study, draws up its processing craft plan, determines various components the processing technological process. Considered the components the size and the accuracy requirement, embark from the selection mold material, the possible arrangement each components processing's order successively, guaranteed that can produce the qualified components. Through this design, I have understood mold's principle of work and the mold major parts reciprocity, and had a more profound understanding to the injection mold design's entire process.
