Description
Technical field
The utility model is related to casting technique equipment technology fields, and in particular to a kind of large size wheel hub sandbox.
Background technology
Sandbox is the technological equipment for carrying out moulding in casting industry to the part that needs are cast.Generally before parts of Casting first
Carry out wooden model, wooden model is put into sandbox by when moulding, is inserted and is compacted with casting sand, and the cavity that cast is formed after wooden model is removed.It is common
Sandbox to form the cavity of cast using upper and lower sandbox split, the mating surface of upper and lower sandbox is known as die joint.
Large-scale wheel hub in wind-powered electricity generation industry is casting, and wheel hub model silhouette is projected as approximate non-regular hexagonal.It is existing
Have in technology, the moulding of large-scale wheel hub is frequently with all purpose flask.But there are following some problems in all purpose flask in use：
First, installing the threaded hole of trip bolt, threaded hole when sandbox parting flange face is equipped with for upper drag box mould assembling
It is easily damaged after use after a period of time, is difficult to repair after damage, sandbox is caused integrally to be scrapped.Some sandboxes are directly in parting
Holes drilled through on flange face, with hexagon-headed bolt mould assembling, in order to enable turret head is not interfered with sandbox outer wall, parting flange needs are done
Must be wider, one side increases the dosage of material, and on the other hand wider flange makes rigidity of flange decline, after flange stress
It is easily deformed, to influence the quality of die joint.
Second is that thread mill drilling or through-hole need extensive drilling equipment on large-scale sandbox, ease of processing is poor, processing
It is of high cost.
Third, when using all purpose flask, the size of large-scale wheel hub and sandbox can not achieve Optimized Matching, cause sand using amount it is big,
Sandbox overall weight weight, production cost are high；Moreover, all purpose flask is easier to make when larger relative to the accessory size of moulding
The knockout defect of type.In addition, its difficulty turned over also increases, safety declines after weight increase for large-scale sandbox.
Fourth, sandbox needs often lifting and turns over, the steel wire rope of hanging axis and lifting when lifting and turning on its sandbox
Between frictional force it is larger, steel wire rope easily rub it is bad, to reduce the service life of lifting rope and the safety of lifting.
Utility model content
