【正文】 velopment direction ,Many modern industrial development and the improvement of the technical levels ,Largely depends on the development of die and mould industry level. This paper mainly introduced the plastic injection mold insurance seat of design.First through analysis in the design of plastic parts, process characteristics and shape ,choose the proper mould design ,Second is the choice of injection, mcluding injection machine of primaries and injection machine related parameter respectively ,To determine the injection machine；Complete the die structure design again ,Enclose the choice and determination parting ,Cavity number of determining and cavity arrangement ，The design of gating system ,Molding parts structure design ,Corepulling mechanism design, selection of launch institutions, cooling system design, standard formwork choice ,Finally calculated for molding parts size, determine the process parameters.Using this mold can guarantee plastics dimension appearance and surface requirements , And low cost, simple structure and easy to open mold, high efficiency, with strong practicability.
