With the developing of the plastic industry, the plastic injection mould has already been become one of the main methods of manufacturing plastic products.
According to the designing of Lu Bao ventilation shutter integration double cavity injection Mould .Firstly, this paper introduced the selection basis and significance of subject ,the development situation at home and abroad , the main topics to be taken by the content and methods, difficulty parts of design and solutions and development prospects of injection mould . And then introduce the whole design process. Analysis the plastic parts, select the injection machine and check some parameters .At last, overall design of injection machine , including geometric shape and size of molding and component design , molten plastic transportation of runner system , the overflow and air-entraining system design which affects the precision of plastic parts. temperature control system in cooling system、separate and remove the molding of plastic parts of ejection mechanism and mould base. With UG three dimension design to draw the appearance of plastic parts. Use the slanted guide pillar and sliding core to complete the pulling action of cavity-hole in this paper. Experiential learning is described in the end of the paper.
