Injection molding of plastic parts in the automotive technology application and practice areas: the rapid development of automobile industry in environmental protection and energy saving premise of global economic growth, the auto industry to become the development trend of plastic and steel automobile revolution. Plastics and composite materials not only reduce about 40% of the quality components, but also to reduce the cost of production is about 40%. Growing international attention to the new car with a plastic material and parts of the development, the amount of plastic parts in cars rose rapidly mixed doubles color injection molding machines, automotive plastics has developed as an important indicator to measure the amount of vehicle design and manufacture of the level. How much amount of automotive plastics has become a measure of the level of car design and manufacture an important indicator of double injection molds, domestic cars more than about 10% of the material made of plastic, plastics in cars is expanding range of applications from car to car interiors external structure; in addition to the amount of polyolefin materials recently applied significant increase in the automotive sector, the automotive industry in the use of polyurethane, reinforced composite materials is also increasing, "plastic steel" for the plastics industry to provide a broader development prospects. More and more car parts is gradually shifting from plastic to metal fabrication and manufacturing. Injection molded products in the automotive components increasingly high proportion of injection molding industry, the automotive industry has become the most critical link in the supply chain. Factors injection molding design takes full consideration. Injection mold by the movable die and the fixed mold composed of two parts, the movable die is mounted on the injection molding machine's movable platen, a stationary die mounted on the stationary platen of the injection molding machine. When the movable mold injection molding and fixed mold casting system and constitute a closed cavity mold when the movable mold and the fixed mold separation in order to remove the plastic. Although the structure of the mold of the plastic varieties and properties, shape and type of plastic injection machine structure and the like may be different and the ever-changing, but the basic structure is the same. Die mainly by gating system, thermostat system, molded parts and structural parts. Gating system and molded parts which are in direct contact with the plastic part, and with plastics and products change color injection molding process, the mold is the most complex and the biggest change, the most demanding part of the finish and precision machining. Gating system means that the plastic nozzle into the flow path from the cavity front part, including the main channel, the cold slug, runner and gate and so on. Forming part refers to the shape of the various parts constituting products, including dynamic simulation, and fixed mold cavity, core, forming stem and an exhaust vent.
