Trimming rolling cutter for machine use for automotive trim injection-molded products

Abstract

The invention discloses a trimming rolling cutter for machine use for automotive trim injection-molded products. The trimming rolling cutter is composed of a shank (1), a cutter bar (2), a cutter head (3) and a spring (4). The shank, the cutter bar and the cutter head of the rolling cutter of the present invention from top to bottom are formed into a spring steel integral component in a cylindrical stepped shape; the spring sleeves the cutter bar; an upper end of the spring is fixedly welded with a lower end face of the shank, while a lower end of the spring is fixedly welded with an upper end face of the cutter head; in use, the following technical solution is adopted: numerical control locating trimming is performed on an automotive trim injection-molded product by using a numerical control engraving and milling machine tool; during working, the automotive trim injection-molded product is clamped on a template on a worktable of the numerical control engraving and milling machine tool, and the shank is clamped by an electric spindle of the numerical control engraving and milling machine tool and rotates at a high speed, and then rolling trimming is realized to flashings by using a cylindrical surface of the cutter head rotating at the high speed along the edges of the automotive trim injection-molded product; as a result, in the trimming to the automotive trim injection-molded products, the purposes of improving the consistency of quality, eliminating defective products and scraped products, improving efficiency and reducing costs are achieved.

Description

technical field [0001] The invention relates to a machine tool, in particular to a machine edge trimming roller knife for trimming the flash of the injection molded product of the vehicle interior by rolling. Background technique [0002] The parting surface of the injection mold will form a sharp flash on the edge of the injection molded product for the automotive interior. Therefore, the injection molded product for the automotive interior must be trimmed to eliminate the flash after injection molding, which is called trimming for short. The scraper is scraped and trimmed manually with a scraper, and the quality of manual scraping and trimming varies from person to person and it is difficult to guarantee, resulting in poor quality consistency of automotive interior injection molding products, many defective products, and scrapped products; in order to ensure the quality, it is necessary to add inspection labor, so that Manual scraping and trimming requires a lot of manpowe...
