The forging type of type produces foundry goods.
Green-sand casting simple process:
---------------unpacking,------castings goes out lower core in polishing---inspection---in sand removal in cast in sandbox locking in mould assembling in moulding
Factory
Wherein before cast, sandbox locking is an important ring, otherwise during molten iron casting, lifts case power greatly, easily occurs lifting case, and molten iron leaks between upper nowel
Go out, it is impossible to water out the phenomenon of qualified products.
After existing moulding, upper nowel mould assembly locking mode normal method has:
1) cast the sandbox of specification, after processing, upper nowel is respectively kept with oblique piece, use open card pin card on oblique, lock.
The weak point of this mode is that sandbox processing charges is high, and input cost is high, and it is generally used for producing in enormous quantities.
2) after upper nowel mould assembly, pushing down sandbox with heavy foundary weight block on top box, the weight of pressured ferrum is offset and is lifted case power.This mode
Removing the foundary weight amount of labour big, and the iron block of shape generally cast by foundary weight, weight is big, and inevitable cost is high.
3), after mould assembling, twine the case handle of rich upper nowel with iron wire, thus upper drag box is locked together.It is disposable that this mode iron wire uses,
Waste is serious, and iron wire twines rich time-consuming long, and production efficiency is low.
Therefore provide one simply, easily and efficiently sand box locking device become people's problem demanding prompt solution.
