Abstract
Description
Technical Field
[0001] The utility model relates to automobile casting processing technology, in particular to a trimming device used for automobile casting processing. Background Art
[0002] At present, in the production process of automobile parts, some parts are die-cast. During the die-casting process, waste materials are generally left on the parting surface or the edge of the active part of the die-cast parts. Therefore, a trimming process is required to cut the excess process waste. Therefore, a trimming device is needed in the processing of automobile castings.
[0003] Existing trimming of automotive castings typically uses a pre-set trimming die with a downward pressure action to cut and trim the components placed inside. After trimming, the removed waste material slides down the material guide troughs on both sides of the trimming die and falls out. Common dies lack a collection mechanism to collect the removed waste, requiring manual collection, which is cumbersome and labor-intensive, and can cause hand scratches and accidents. Furthermore, during the trimming process, some of the waste material is ejected due to the force, potentially posing an unnecessary safety risk to nearby operators. Therefore, we propose a trimming device for automotive castings to address these issues. Utility Model Content
