Research And Application Of Bi-color Injection Molding Technology

Nowadays, along with the peoples’improving quality demands to injection products, more and more new types of injection molding process and technology being developed and applied. Bi-color injection allows use of various of raw material to produce, in order to improve the product’s functionality and appearance. Due to its advantage, bi-color injection molding has irreplaceable broad market. As time goes on and application of rapid development of the industry, its market share will more and more big. Double (multiple) color injection technology as a leading manufacturing technology, its market prospect is well and seed more and more widely used.In this thesis, the mold industry development and the situation of the injection mold have been described and four typical and improved sequential bi-color mold structure such as the core rotary—type bi-color injection structure, the contraction core-type bi—color injection structure, the de-part plate rotary-type bi-color injection structure, the core slide-type bi-color injection structure have been summarized, seesaw mold structure; analysis the processing characteristics and adaptability of mold structure respectively; summarized key points of sequential over molding mold design and products design; The turquoise insulation board as the carrier, analyzes the technological characteristics of the product, the product of the mold parts structure such as parting surface selection, forming parts determination, side parting core-pulling mechanism, pouring system launch and reset mechanism for analysis and design. Finally make sure overall structure. And introduction introduces the CAD/CAE/CAM, and discussed its application in turquoise mold design. Moldflow10software as the carrier, introduces the software module, and introduces the use of the mold design, and the insulation board filling process of the digital simulation analysis. Prove the feasibility of the design scheme. And then to Pro/E as the carrier, the paper introduces the application of CAD technology in mold, detailed introduction mold diagram in Pro/E of the drawing process, the results of study is useful to turquoise process design.
