It is limited, so that the protrusion of lower end can not move inward, limiting cylinder 46 is mainly in cylinder type hollow casting
Between partially limit the adjustment of length so that the protrusion of cylinder type hollow casting top and bottom point is withstood, cylindrical casting
It not can be carried out mobile and rotation, knockout motor 41 drives the casting limited between upper arc panel 44 and arc lower plate 48 to be centrifuged
Movement, it is intracavitary that the molding sand of cylinder type hollow cast-internal throws away type under the influence of centrifugal force；
3, when the biggish crystalloid molding sand of generation falls in protection bushing 35, dispersion plate 411 is driven by knockout motor 41,
In rotary course, with biggish speed and the molding sand of bushing 35 will be protected to collide, multiple collision can will be biggish
Crystalloid molding sand is broken up to little particle molding sand, and the compound molding sand of breaing up reused will be fallen from the hole on protection bushing 35
Under, since the rotation of casting can generate biggish relative wind, there is the phenomenon that fugitive dust, so baffle 410 can reduce rotation
When air inflow so that in rotary course generate relative wind scale reduce, reduce generate fugitive dust the phenomenon that, knockout process
In there is no collisions to casting, improve the quality of casting；
4, after the molding sand in cylinder type hollow casting is largely all thrown out, due to manually clearing up the molding sand of inside attachment
Harder, so being cleared up with cleaning plant 5, knockout motor 41 stops operating, and lifting cylinder 54 will place column 510 to hollow
The inside of casting pushes, and rotating electric machine 52 is started to work at this time, strikes off cylinder 57 and is initially to be less than the position of cavity radius, it
Cylinder 57 is struck off afterwards and pushes the scraper plate 58 pressed on push rod 59 to cavity inner wall, so that scraper plate 58 is tightly bonded by pressing push rod 59
Inner wall, the attachment molding sand on casting cavity inner wall will gradually fall off under the action of scraper plate 58, and cleaning cylinder 55 pushes cleaning brush
56 clean up the inner wall after scraping, so that the molding sand of cleaning inner wall is simple and fast, realize to cylindrical cavity casting
Inner cavity automation cleaning and knockout function, solve the damage that the collision between existing shakeout and casting mold causes mo(U)ld face
Clamping when a large amount of fugitive dusts occur, fall sand to cylinder type hollow casting during bad, knockout is unstable, cannot be effectively reduced big
The generation of burl bulk molding sand, and the problems such as cleaning unclean larger to the inner cavity cleaning difficulty of hollow casting, have reached purpose.
