The car headlight circuit distribution socket of injection mold design
Abstract: With the rapid development of mechanical manufacturing industry, the developmentof mold is shrunk, which join in a large number of high-tech advances in injection technologyand product quality and other aspects . In our period of mold design, if we are not notice theinjection conditions and requirements, for example, the injection pressure and time, etc., then theinjection molding after the final would be difficult to achieve our previous design. Thegraduation project content is car headlight circuit distribution outlet for the study, first given inadvance to tutor injection with Pro/E three-dimensional modeling, and based on this export moldcavity and core, then complete the mold design. After a gradual selection of injection moldingmachines, gates and determine a reasonable position to analyze and arrangement of coolingwater and the like. Finally, mold flow analysis software for injection gate, analyze and evaluatethe position of bubbles, filling quality, cooling quality, filling time, weld marks, etc., and then getin line with our requirements mold design.
