Description
Technical field
The utility model relates to the foundry sand box structure, relate in particular to a kind of can be with the Quick locking structure of the sandbox of the fast and reliable locking of upper and lower sandbox.
Background technology
Lift case when preventing from pouring into a mould in the Foundry Production and metal run out, usually lock upper drag box with foundary weight or with plain bolt, inefficiency, labour intensity is high.The method of existing locking sandbox mainly contains two kinds: the first is to prevent from lifting case with heavier iron block on the cope as pressing case iron to be pressed in, the shortcoming of this method is that reliability is not high, when foundary weight weight when lifting case power, cope can be lifted by molten iron and cause runout; The second is gap on the abutted flange of upper and lower sandbox, and with plain bolt upper and lower sandbox is locked, and the shortcoming of this method is to reduce intensity and the rigidity of sandbox, and locking speed is slow, and labour intensity is high.
Summary of the invention
The utility model has mainly provided a kind of simple in structure, intensity is high, can be with the Quick locking structure of the sandbox of the fast and reliable locking of upper and lower sandbox, having solved the sandbox locking mechanism that exists in the prior art causes the intensity of sandbox and rigidity to reduce, and locking speed is slow, the technical problem that labour intensity is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Quick locking structure of sandbox, comprise drag box and be located at cope on the drag box, outside wall surface at described drag box is provided with lower lug, outside wall surface at cope is provided with the upper lug corresponding with lower lug, between lower lug and upper lug, be provided with the donought card, the donought snap ring is enclosed within outside lower lug and the upper lug, be connected with positioning screw at the donought card corresponding with lower lug or upper lug, the medial extremity of positioning screw vertically is connected on the outer ring surface of lower lug or upper lug.By upper, the outside correspondence of drag box arranges, lower lug, and on two, the outer sheathed donought card of lower lug, again by the positioning screw that spins at the donought card, the medial extremity vertical top of positioning screw is connected on lower lug or the upper lug, the lower lug relative with positioning screw or upper lug outside apical grafting are on the inner ring surface of donought card, during use, can be with upper by inside screw-in positioning screw, the drag box quick locking, slightly outwards screw out positioning screw during dismounting and can take off the donought card, not only convenient to disassembly, reduce workman's labour intensity, and do not affect sandbox intensity, simple in structure, reliable lock.
Upper and lower lug can be the various shapes such as circle, polygon, as preferably, described lower lug is that integral type is connected to the rectangular horizontal boss on the drag box, upper lug is that integral type is connected to the rectangular horizontal boss on the cope, and lower lug is located near on the outside wall surface of drag box upper surface, and upper lug is located near on the outside wall surface of cope lower surface.Upper and lower lug is the rectangular horizontal boss, makes the positioning screw apical grafting on the horizontal plane of upper and lower lug, guarantees upper and lower sandbox reliable lock; Upper and lower lug integral type connects, and intensity is high; Upper and lower lug is positioned near on the outer outside wall surface of upper and lower sandbox adjacent face, saves donought snap ring material, easy disassembly.
The donought card can be the various shapes such as circle, polygon, and as preferably, described donought card is rectangle, and relative two sides are parallel with the lateral surface of corresponding lower lug or upper lug on the donought card.When the donought card is rectangle, can be clamped on the upper and lower lug by two parallel edges, guarantee that the donought kayser is tightly reliable.
As preferably, the outboard end integrated coaxial of described positioning screw is connected with locating dowel, radially is provided with positioning through hole on locating dowel, and sliding plug has rotating tension bar in positioning through hole.By the outboard end at positioning screw locating dowel is set, is disposed radially positioning through hole in locating dowel, and switch through moving pull bar in the positioning through hole interpolation, can easily drive the positioning screw spinning in and out by rotating tension bar.
As more preferably, be provided with two positioning through hole in described locating dowel, two positioning through hole are right-angled intersection and distribute.Be the positioning through hole that right-angled intersection distributes by arrange two in locating dowel, conversion rotating tension bar position when being convenient to the positioning screw spinning in and out.
As preferably, described positioning screw is screwed on the donought card by trapezoidal thread.Trapezoidal thread intensity is good, guarantees that upper and lower sandbox locking is solid and reliable.
Therefore, the Quick locking structure of sandbox of the present utility model has following advantage: by upper, the outside correspondence of drag box arranges, lower lug, on two of correspondence, the sheathed donought card in the lower lug outside, and at the positioning screw that radially spins of the donought card corresponding to upper lug or lower lug side, the medial extremity vertical top of positioning screw is connected on lower lug or the upper lug, the lower lug of the opposite side relative with positioning screw or upper lug apical grafting can be with upper at the donought card, the drag box quick locking, slightly outwards screw out positioning screw during dismounting and can take off the donought card, not only convenient to disassembly, reduce workman's labour intensity, and do not affect sandbox intensity, simple in structure, trapezoidal thread intensity is good, reliable lock.
