Design of taillights Block modeling
for hot runner mold
Abstract: The topics to rear seat as the research object, its structure and process analysis, mold concrete structural design, the use of hot runner mold systems, including nozzle design, the specific parameters of manifold selection and design, etc., and using a lifter side core structure to solve the problem of mold forming within the tank, molded parts using mosaic structure, stripping using a putter introduced institutions to ensure uniform cooling effect of the cooling duct layout and achieve injection molding and meet quality technical requirements. Rear seat and hot runner mold design is based on modeling software UG rear seat as a development platform to complete the three-dimensional plastic parts to build the data model. The topic is open courses in school, based on the integrated use of advanced modeling knowledge creation taillight seat model in order to extract the mold cavity production and manufacturing technology, combined with practical knowledge of production, the use of UG NX software to solve the problem, which can improve their analysis, mapping, operation and other comprehensive ability.
Key words: Injection mold; runner; side core; modeling
