Injection mold design with truck steering lampholder based on Pro/E
Abstract:Trucks turn signal lamp holder which is small size and thin wall, multiple cores,complex structure is the main support part of the turn signal.the cost of One mold multi-cavitymould manufacturing is high and the cycle is long, difficult to processing. According to thecharacteristics of the parts above, the parameterized design based on Pro/E software andinjection mold design is carried out on the truck turn signal lamp holder. First of all, the moldcore, cavity and core are combined with separate processing core, which is based on thetraditional monolithic machining method improved,Simplify the manufacturing process, to avoidthe mold damage and to manufacturing, decrease the difficulty of mold manufacturing to shortenthe manufacturing cycle. Second, small complex plastic side concave oblique core-pulling, slideblock and side core integration design, cooperate with chocking piece part adopts the roundedtransition, solve the widget Angle of stress concentration, greatly improve the die life. Finally,the inclined guide pillar directly fixed on the chocking block, namely the wedge block andinclined guide pillar is fixed plate integrated design, through the screw on the fixed template,improve the methods of chocking block are made separately, simplified the mould structure,reduce the mould manufacturing cycle. Results show that compared with the traditional designmethod, the parametric design of Pro/E software functions of 3 d modeling, mold design and mold frame assembly module into an organic whole, greatly shortens the time of mold designand save design costs, reduce the manufacturing difficulty.
