Abstract
The invention relates to a mud core unloading device for cast mud cores. The mud core unloading device is characterized by comprising a metal nut, a metal gasket, a metal lifting hook and a metal lifting ring, wherein the upper part of the metal lifting hook is connected in a mud core unloading channel reserved in an outer-molding sand mould in a penetration manner; the upper end of the metal lifting hook passes through the metal gasket reserved in the outer-molding sand mould, and is screwed with the metal nut for pressing the metal gasket to fixedly connect to the outer-molding sand mould; the metal lifting ring is pre-embedded into a mud core sand mould; and the metal lifting hook extends into the mud core sand mould, and is connected to the metal lifting ring.
Description
Technical field
The present invention relates to a kind of casting frock, core device under specifically 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 winching 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, the invention 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 used in the present invention 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 the metal suspension ring in loam core, top cross-under metallic gasket, metal nuts of then screwing on are caught in metal lift hook bottom, tighten 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 the present invention 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 lower loam core passage 3 that model sand mold 1 is reserved outside, the upper end traverse of metal lift hook 4 is reserved in the metallic gasket 5 in outer model sand mold 1 and the metal nuts 6 that spins compresses the metallic gasket 5 outer model sand mold 1 of fixing connection, 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.
Claims (2)
