Description

Technical Field

[0001] The utility model belongs to the technical field of automobile enclosure manufacturing, and more specifically, particularly relates to a rapid prototyping integrated automobile enclosure component forming die. Background Art

[0002] In actual automobile enclosures, such as side skirts, injection molding is mostly used in actual production and manufacturing. In addition to guiding air flow and reducing wind resistance, the vehicle enclosures are also important decorative parts of the vehicle. Currently, a large number of vehicle enclosures also involve painting and other work after the injection molding process is completed. It can be seen that the manufacturing precision and quality of the vehicle enclosures are extremely important. The current vehicle enclosure molding molds are not convenient for demolding and disassembly of the interior of the enclosure, which can easily damage the appearance of the enclosure. At the same time, the accuracy of the mold will inevitably decrease after long-term use, which is not convenient for one-piece and fast trimming. Manual trimming is required later, which affects manufacturing efficiency. At the same time, the controllability of manual operation accuracy is poor, and the trimming effect is not good.
