Abstract
The utility model relates to a loam core device under mo(u)ld core, its characterized in that: including metal nut, metallic gasket, metal lifting hook and metal rings, the upper portion cross -under of metal lifting hook is in the lower loam core passageway that the external mold sand mould was reserved, and the upper end of metal lifting hook is passed the metallic gasket of reservation in the external mold sand mould and is connect the metal nut to compress tightly metallic gasket fixed connection external mold sand mould soon, and the metal rings are pre -buried in the sand mould of loam core, and the metal lifting hook stretches into loam core sand mould clasp joint metal rings.
Description
Technical field
This utility model relates to a kind of casting frock, core device under a kind of mo(u)ld core for lifting by crane lower loam core.
Background technology
When needing the cast casting in lower loam core, need to winch to aerial corresponding mold and carry out lower loam core, conventionally employed clamp loam core, clamping force is little, and loam core is sling easy to fall off, and lifting instability, clamping force is excessive, damages loam core, affects castability.
Summary of the invention
For Shortcomings in lifting, lower loam core in prior art, this utility model provides a kind of simple in construction, can effectively guarantee core device under the mo(u)ld core of the safe and stable lifting in loam core, the operation of lower loam core.
The technical solution adopted in the utility model is: core device under a kind of mo(u)ld core, it is characterized in that: include metal nuts, metallic gasket, metal lift hook and metal suspension ring, in the lower loam core passage that the top cross-under model sand mold outside of metal lift hook is reserved, the upper end of metal lift hook is through being reserved in the metallic gasket in outer model sand mold and the metal nuts that the spins compression metallic gasket outer model sand mold of fixing connection, metal suspension ring are embedded in the sand mold of loam core, and metal lift hook stretches into loam core sand mold clasp joint metal suspension ring.
Described metal nuts is sunken in outer model sand mold and is cast sand seal dress.
Built-in metal suspension ring in the structure of loam core, suspension ring structure is combined with loam core sand, plays support stress；Outer model sand mold leaves the lower loam core passage placing metal lift hook, and metal lift hook bottom is caught on the metal suspension ring in loam core, top cross-under metallic gasket, metal nuts of then screwing on, tightened rear foundry sand and build.Lower loam core simple in construction, easy to operate, safety coefficient is high.
Accompanying drawing explanation
Fig. 1 is that this utility model uses structural representation.
In figure: outer model sand mold 1, loam core 2, lower loam core passage 3, metal lift hook 4, metallic gasket 5, metal nuts 6, metal suspension ring 7.
Detailed description of the invention
It is described further below in conjunction with accompanying drawing.
Shown in Fig. 1, under a kind of mo(u)ld core, core device includes metal nuts 6, metallic gasket 5, metal lift hook 4 and metal suspension ring 7, in the top cross-under of the metal lift hook 4 reserved lower loam core passage 3 of model sand mold 1 outside, the upper end of metal lift hook 4 is through being reserved in the metallic gasket 5 in outer model sand mold 1 and the metal nuts 6 that spins compresses that metallic gasket 5 is fixing connects outer model sand mold 1, metal suspension ring 7 are embedded in loam core sand mold 2, and metal lift hook 4 stretches into loam core 2 sand mold clasp joint metal suspension ring 7.Metal nuts is sunken in outer model sand mold and is cast sand seal dress.
