Description

Technical Field

[0001] The utility model relates to the technical field of annular runner trimming dies, and specifically relates to a trimming die structure for removing an annular runner. Background Technique

[0002] In the die-casting industry, runners are often set at the injection points of molten metal during the production of castings so that the molten metal can flow smoothly into the mold cavity. The annular runner is one of the common runner designs. After the casting cools and solidifies, the runner needs to be removed to complete the final shape of the product. Due to the complex shape of the annular runner, a large shearing force is required to remove it. Existing shearing machines may not be able to provide sufficient shearing force, and when shearing in the conventional demolding direction, the shape of the runner on one side is always opposite to the cutting edge, and the required shearing distance of the annular runner is long, which is extremely prone to chipping, resulting in product scrapping and incomplete runner shearing. Therefore, a new annular runner trimming die structure is designed. Content of the Utility Model
