【正文】 check of some related parameter, and introduce the mold processes simply. Through the entire design process that can be achieved in the mold plastic parts required in this process. Based on the volume and determine the process performance of plastic injection molding method using plastic parts production. The product is desighned for mass production, so the design of the mold requires a high injection efficiency, and the gating system to be able to automatic mold ejection., in addition to use site gate according to product structural feature, so we choose a single sub serface injection mold, site gate automatic ejection structure. Mold cavity onecavity mold, gating system using site gate forming, introdued extrusion device to plete sixth putting the introduction of plastic parts. In consideration of the factors such as the performance and so on, use circulating cooling system to cool products.
