Mold for injection molding

The invention belongs to the technical field of molds, and particularly relates to a mold for injection molding. The mold comprises an upper mold plate, a lower mold base and a controller. The upper mold plate and the lower mold base are fixedly connected through first hydraulic push rods. The lower end of the upper mold plate is fixedly connected with an upper mold. The upper end of the lower mold base is fixedly connected with a lower mold. Guide columns are installed between the upper mold and the lower mold. According to the mold, due to the arrangement of a scraping plate, when a formed workpiece is subjected to mold release, the scraping plate can scrape burrs on the edge of the formed workpiece, the situation that a worker carries out burr treatment on the formed workpiece is avoided, the labor intensity of the worker is reduced, the situation that a large amount of money is spent on purchasing related burr treatment equipment is avoided, and the cost is saved; and a positioning groove is matched with
