A sand scraping mechanism for cast iron casting

Abstract

The invention discloses a sand scraping mechanism for casting pig iron castings, which comprises a chain plate erected by two gear cylinders, the gear cylinder is composed of a cylinder body and a gear bar, and the chain plate is composed of linking units, each linking unit includes Symmetrically threaded straight plates and connecting shafts, adjacent linking units are connected in series through rivets, and the connecting shafts are respectively equipped with frosted pressure rollers, brush rollers and rectangular strips; The bottom of the rod is fixed to the triangular support frame and the universal wheel; the driving shaft is connected to the motor, and the sand casting frame is located directly below the chain plate. The present invention uses the chain plate to load the sanding roller, the brush roller and the rectangular bar, and integrates the advantages of the deflection plate scraping-rolling brush head cleaning-roller pressing cylinder compaction, etc., so that the surface of the casting sand can be quickly realized. Flat state; and the whole sand scraping process is relatively simple and labor-saving, suitable for assembly line scraping treatment, saving casting time, conducive to the formation of uniform and standardized casting standards, and improving the quality of castings.

Description

technical field [0001] The invention relates to the technical field of casting of pig iron castings, in particular to a sand scraping mechanism for casting of pig iron castings. Background technique [0002] Sand casting refers to the casting method that produces castings in sand molds. Because the molding materials used in sand casting are cheap and easy to obtain, and the casting mold is easy to manufacture, it can be adapted to single-piece production, batch production and mass production of castings. For a long time, it has been the main process in the production of pig iron castings. [0003] When casting, it is generally necessary to shake the sand mold first, and then use a scraper to scrape off the excess sand on the surface of the sand mold, so that the surface of the sand mold is flush with the frame of the frame. The sand scraping process in the existing casting technology is generally manual operation, which is time-consuming. Effortless, in need of improvement....
