Abstract
The utility model discloses a combined sand strike-off mechanism which consists of a flat scraper and a screed. The flat scraper is positioned on the upper end, and the screed is installed on an upright post through a rotating shaft, while the lower end of the screed is provided with an adjusting bolt. The utility model is characterized in that the back of the screed is connected with a cylinder which is provided with a dust-preventing board and can drive the flat scraper to conduct the falling sand strike-off, and a hob is provided on the sand feeding type, which conducts sand strike off for the sand feeding type. The combined sand strike-off mechanism can complete a plurality of super large and high castings under the circumstances of restriction by the tooling equipment, thereby exerting an extension effect. Moreover, the practice has proved that the utility model has quite remarkable advantage and can completely meet the technological requirements. The utility model is convenient for installation, simple in maintenance, thereby guaranteeing the production quality and improving the forming rate.
Description
Technical field
The utility model is a kind of combined type sand mold mechanism of strike-ofing.
Background technology
At present, strike-off after the moulding of static pressure mo(u)lding line and use fixed scraper, it can satisfy the technological requirement of common castings production.But because die cavity is big, and it is few that sand adds charge, the upper surface layer of sand is thin, when scraper is strike-off, will go up sand mold easily and break or scratch, and directly influences the quality of production and output, causes sometimes and is forced to stop production during to production super large, superelevation shape foundry goods.
Summary of the invention
In order to address the above problem, the utility model changes fixed scraper into adjustable combined type scraper.The utility model is easy for installation, and is easy to maintenance, guaranteed the quality of production, improved ratio of briquetting.
The combined type sand mold mechanism of strike-ofing is made up of flat scraper, scraper plate, flat scraper is contained in the upper end of scraper plate, scraper plate is installed on the fixed frame by rotating shaft, and the lower end of scraper plate links to each other with adjustment bolt on the fixed frame, and it is characterized by: the back side of scraper plate links to each other with cylinder, dust excluding plate is housed on the cylinder, the other end of cylinder is contained on the fixed frame, and cylinder drives flat scraper following sand mold is strike-off, and passes through the place at last sand mold, hob is installed on the frame, and hob rotates last sand mold is strike-off.
The strike-off hob of mechanism of combined type sand mold is made up of four each scrapers, and four scrapers evenly are installed on the bearing.
Description of drawings
Fig. 1 is the combined type sand mold mechanism's front view of strike-ofing.
Fig. 2 is the combined type sand mold mechanism side view of strike-ofing.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The combined type sand mold mechanism of strike-ofing is made up of following part: flat scraper 1, scraper plate 2, upper hinge seat 3, dust excluding plate 4, cylinder 5, hinge seat 6, rotating shaft 7 down, adjust bolt 8, fixed frame 9, motor 10, motor pulley 11, hob belt pulley 12, hob 13, bearing block 14, frame 15 and form.Flat scraper 1 is contained in the upper end of scraper plate 2, scraper plate 2 is installed on the fixed frame 9 by rotating shaft 7, the lower end of scraper plate 2 links to each other with adjustment bolt 8 on the fixed frame 9, it is characterized by: the back side of scraper plate 2 links to each other with cylinder 5 by upper hinge seat 3, dust excluding plate 4 is housed on the cylinder 5, the other end of cylinder 5 is contained on the fixed frame 9 by following hinge seat, cylinder 5 drives 1 pair of drag box 18 sand mold of flat scraper and strike-offs, pass through the place at cope 18 sand molds, hob 13 is installed on the frame 15, and hob 13 rotates strike-offs to last sand mold.
The strike-off hob 13 of mechanism of combined type sand mold is made up of four scrapers 16, and four scrapers 16 evenly are installed on the bearing 17.Hob 13 assemblies are installed on the bearing block 14, and motor 10 drives motor pulley 11 and hob belt pulley 12 rotates hob 13.
The combined type sand mold mechanism of strike-ofing finishes drag box 18 and 18 two sand mold faces of cope task of strike-ofing.Because German KW company static pressure mo(u)lding line, main frame adopts through installation form up and down, upper and lower sandbox sand mold is simultaneously after finishing the moulding task in two main frames, by main frame turnover case push rod upper and lower sandbox sand mold being pushed to the combined type sand mold strike-offs in the mechanism, at this moment cylinder 5 drive flat scrapers 1 scrape the surplus sand in nowel bottom surface and case mouth 1-2mm, keep its flatness.Drive flat scraper 1 by cylinder 5 again and be retracted to the home position, space with 18 casees mouths maintenances of cope 50mm, at this moment cope 18 enters duty, but by hob 13 the surplus sand of cope box top is cleared up the surplus sand amount retained in top to 20-30mm again, reaches the planarization of sand mold face.
