85L storage box mold design
Abstract：Mold is an important modern industrial production technology and equipment, known as "the mother of industry." And again in the entire mold injection mold industry thriving, extremely rapid development in the automotive, aerospace, communications, electronics, home appliances and other fields has a very wide range of applications. This graduation project selected product is 85L of storage boxes, storage boxes as common household storage containers, versatile, can be used to place clothing, fruits and vegetables, toys and so on. Meanwhile, the storage box with environmentally friendly, non-toxic, odorless, light weight, easy to clean, neatly stacked, etc., is practical merchandise our home life. Storage box size is about 683x432x358, using Pro / ENGINEER mold structure design, using multiple sets of lateral pulling mechanism and a hydraulic drive system, while the use of advanced hot runner system four o'clock needle into the plastic way ,using CAD drawings in 2D drawing.
KeyWords：Injection mold; hot runner systems; lateral Pulling
