Equipment and method for improving sand lined casting efficiency

Abstract

The invention relates to equipment and a method for improving sand lined casting efficiency, and belongs to the technical field of iron sand lined casting. The equipment comprises a supporting frame composed of an upper beam, a base and a vertical pillar between the upper beam and the base, a sand adding and jetting device, and a rotating mechanism arranged on the base. The equipment is characterized by further comprising a four-station working platform, a lifting type sand jetting head and a lifting type roller bed opening and closing mechanism, wherein the four-station working platform is fixed on the rotating mechanism; the lifting type sand jetting head is connected at one side of the upper beam, and the lifting type roller bed opening and closing mechanism is connected at the other side; the lifting type sand jetting head and the lifting type roller bed opening and closing mechanism are respectively arranged on left and right sides; and the four-station working platform is arranged below the lifting type sand jetting head and the lifting type roller bed opening and closing mechanism. The equipment disclosed by the invention is reasonable in structure and design, convenient to clean mold, high in sand lined casting efficiency and convenient for users to operate.

Description

technical field [0001] The invention relates to a casting device and method, in particular to a device and a method for improving sand-covered molding efficiency, belonging to the technical field of iron mold sand-covered casting. Background technique [0002] Sand-coated iron mold is a special casting process that blows coated sand into the gap between the mold heated to a certain temperature and the iron mold, and hardens it into shape. With the advantages of its own technology, and with the development of the automobile industry and With the rise of the cement industry, the application range of sand-coated iron molds has become wider and wider, especially suitable for the mass production of small and medium-sized castings, so the sand-coated iron mold production line has been widely promoted. [0003] As the core equipment of the production line--sand-covered molding machine, its molding efficiency is the main factor determining the speed of the production line. There are...

[0006] Chinese Patent No. 201220113604.3 discloses a utility model patent named "a sand-covered molding machine", which includes a frame, the frame includes a top box and a column connected to the bottom of the top box, and the bottom of the top box is set There is a sand-covered cover, and a support roller table is set under the sand-covered cover. The support pipe extends to both sides to form a conveying roller table section, and a stopper is arranged on the support roller table. Although the structure of this patent is simple, there is no mold cleaning, etc. structure, so there are still the above defects

[0007] China Patent No. 200820085552.7 discloses a utility model patent named "Sand-coated molding machine adapted to automatic production line". This patent moves in and out by rails, and moves the sand-coated iron mold from directly above the mold to the outside of the mold. Clearing up a certain space for mold cleaning facilitates the cleaning work to a certain extent, but for the entire sand-covered molding process, the five processes are still concentrated in the same station, which has no substantial impact on the molding efficiency. improved, so there are still the above defects
