Description

An Injection Mold for an Inner Parting Fender

technical field

The utility model relates to the field of injection molds, in particular to an injection mold for an inner split fender. the

Background technique

At present, the main direction of the world's automotive material technology development is lightweight and environmental protection. The fenders of ordinary traditional cars are sheet metal parts that are combined with multiple complex processes such as stamping, stretching, and edge trimming. The production cycle is long and the efficiency is low. And scrap rate and production cost are all very high, and, because use many heavy metal raw materials, have increased vehicle body weight and increased energy consumption emission. At present, we use injection molds instead, and use plastic PPO/PA to inject fenders to greatly reduce the weight of the car body and lower fuel consumption, so it is more environmentally friendly and energy-saving, and this plastic has better deformation resistance. Automatic recovery does not require repair. the

In the past, the outer parting was generally used in the development of the mold for the fender. The outer surface of the product injection molded by the outer parting mold will have a parting line. The injection molded product needs to be polished and then painted, which increases the work intensity, and affect the appearance quality. As the requirements for the appearance of mid-to-high-end automobile fenders are getting higher and higher, in order to prevent the parting line at the fillet of the product from destroying the integrity of the fillet, someone designed the inner parting, which means the appearance is visible The surface is hidden in the cavity, and the internal parting mold solves the problem of the parting line on the appearance of the fender, but the structure of the internal parting mold causes R angles at both ends of the cavity, so that the product cannot be separated from the cavity, making it difficult to release the mold , if the mold is forced out, it will cause strain or deformation at the R corner, which will also affect the appearance quality. the
