Design of Cover Injection Mould
Abstract： First to design of the product process analysis and calculation, the plastics used by the propylene, butadiene styrene three monomers copolymerization and become ABS for material, then on the basis of the analysis and calculation to determine molding process solutions for exactly a cavity, push rod launch, point runner, single parting surface, runner set inside the mainstream way adopts cone, selection of formwork for standard formwork, guide pin guide with the installation of Z1 installation way, and on the basis of this total into the mold of assembly structure design and size determination. On the basis of the main parts especially injection mold size discusses h0 during the design and calculation, the plastic molding related to reference through all kinds of plastic material and mould design manual, and through the calculation to determine the specific structure and size mold and molding parts related size, through continuous calculation and modification, and in guiding teacher of meticulous care and patience under guidance of uninterrupted repeated revision, eventually independent completed the graduation design. In the design process, the main forming parts adopt insert or structure, beneficial to the processing.
In addition, the graduation design is learned in my university of knowledge comprehensive inspection and examination, pass the graduation design makes me understand and master the many deeper knowledge, and the whole process is done independently, promoted oneself ability, in the whole design process, introduces the basic characteristics of molded parts material and forming characteristics, die structure composition, structure characteristics, working principle, design principle, the injection molding machine relevant parameters, mould material and heat treatment requirements, etc. Among the gating system, molding parts, structure parts, launch institutions and exhaust system, cooling system, and presented.
Key word: injection mould; gating system; side gate
