Abstract
The utility model relates to a moulding tool for the casting production process of castings, and in particular relates to a water tower type large sand box for casting. The sand box is characterized by comprising a hollow sand box body with an inverted splayed structure, wherein the longitudinal section of the lower part of the sand box body is square, and the longitudinal section of the upper part of the sand box body is inverted trapezoidal; box plates are arranged at four joints of the sand box body with the inverted splayed structure; internal box clamping mouths are formed in the box plates. The sand box disclosed by the utility model is unique in structure, light in weight, convenient to operate, small in sand consumption and strong in universality.
Description
Technical field
The utility model relates to a kind of foundry goods in foundry production moulding frock, especially relates to the tower large-scale sandbox of a kind of casting water.
Background technology
Sandbox is one of technological equipment indispensable in castings production, selects suitable parameter, structure reasonable in design, to growing Foundry Production, has very large practical value.The structure that mostly is single wall same profile of the design of tight flask, is designed with handle or hanging axis for overturning and carrying, and tank wall has a considerable amount of steam vents.Fastening for the ease of mould assembling, prevent foundry goods runout, the profile of a whole set of sandbox is identical, be the I font sandbox of design, but such design, for some special products, can make the grit consuming amount of product very large, and placer iron is than high, the fast cooling that is unfavorable for foundry goods, causes that the production cycle is long, cost is high, the situation of poor performance.Products of mining machine is to be similar to Y-shaped foundry goods, up big and down small, adopts the sandbox of conventional method design, mold thickness is large, and placer iron ratio reaches 8:1, in moulding, mulling and mould assembling process, energy resource consumption is many, waste resource and sandbox weight large, in operating process, there is potential safety hazard.After cast, because foundry goods sand is around many, cause the cooling rate of foundry goods slow, the production cycle is long, properties of product decline, and has a strong impact on the assurance of normal production and product quality.
General sandbox sidewall, skew wall and bottom surface be designed with two kinds of methods: 1) grid type case band, cannot guarantee hanging sand effect and intensity, be prone to after molten iron cast, high temperature liquid iron and gravity crush sand mold, cause foundry goods to be scrapped; 2) all with steel plate, surround, form the space of sealing.When the method causes product-forming, back-up sand is very difficult, and molding sand consolidation is bad, is prone to casting flaw.
Up to the present, also there is no a kind of device that overcomes above-mentioned defect.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, provides that a kind of structure is unique, lightweight, easy to operate, sand using amount is little, the tower large-scale sandbox of a kind of casting water of highly versatile.
The utility model is realized in the following way:
The tower large-scale sandbox of a kind of casting water, it is characterized in that: it comprises that the nowel longitudinal section of a hollow is the sandbox body that is down " eight " word structure square, top box longitudinal section is inverted trapezoidal, four junctions of sandbox body in " eight " word structure are provided with case oralia, are equipped with internal card case mouth on each case oralia;
On the centre circle of the sandbox body of described " eight " word structure, with the case band of thick 30mm, wide 150mm, form the latticed sidewall of 300mm * 300mm, the plane at case band place becomes the oblique angle of 115 ° with the horizontal plane of mould assembling, on each case band, be fixed with the hanging sand bar of 150mm*30mm * 30mm, hanging sand bar becomes the oblique angle of 135 ° with horizontal plane simultaneously;
The top box of described sandbox body and nowel are general four jiaos of sandboxes;
Four fixing handles that hang are set on two opposite side in the large mouthful place of described sandbox body top box, and a hole is hung in two other opposite side setting.
The utility model has following effect:
1) structure is unique: the sandbox that the utility model provides is according to the structure of Y type foundry goods, design water tower type sandbox, makes sandbox with type, and the middle sandbox connecting adopts the structure of " eight " word, four junctions at " eight " word are designed with case oralia 1, select up and down differently contoured all purpose flask; Due to the inclined-plane that " eight " word centre circle is down, the utility model is taked the method for fence lattice, when facilitating back-up sand, guarantee the intensity of hanging sand, concrete grammar is: on the inclined-plane that falls " eight " word, use thick 30mm, the case band of wide 150mm, form the latticed sidewall of 300mm * 300mm, the plane of case band becomes the oblique angle of 115 ° with the horizontal plane of mould assembling, welds the hanging sand bar of 150mm*30mm * 30mm on each case band simultaneously, and hanging sand bar becomes the oblique angle of 135 ° with horizontal plane.This design can guarantee that the minimum mold thickness 300mm in inclined-plane just can produce the foundry goods over 70T.
2) safe and reliable: the utility model is by all having designed case oralia falling two terminations of " eight " word, on each case oralia, all designed internal card case mouth, this design is very practical for large-scale sandbox, effectively reduced the overall size of sandbox, be convenient to sandbox handling and mould turnover operation, meanwhile, card case mode is safe and reliable.
3) reduce the overall weight of sandbox, reduce costs: the sandbox that the utility model provides is except centre circle selects " eight " word special shape mo(u)lding box, and top box and nowel all adopt general four jiaos of sandboxes, strengthen the versatility of sandbox, can at utmost reduce sand using amount; The overall weight that reduces sandbox, reduces costs.
4) reduce the mould turnover height of sandbox, be convenient to upset: the utility model hangs handle in large mouthful of place's design and installation of " eight " font sand mold, make the center of gravity deflection small end of sandbox.So, can facilitate sandbox to overturn after moulding back-up sand; Four fixing handles that hang are set on two opposite side at the large mouthful place of " eight " word, and a hole is hung in two other opposite side setting, can insert the movable handle that hangs.This feature is when upset, by 4 movable hanging taking down, utilizes 4 fixing hanging upset, and during sandbox upset, landing ground is a line or a plane, and the casting mold distortion of avoiding a contact to cause, meanwhile, reduces the mould turnover height of sandbox, is convenient to upset.
5) simple to operate: the sandbox that the utility model provides is easy to moulding back-up sand, handling upset, the fastening operation of mould assembling.
6) raise the efficiency: the sandbox sand using amount that the utility model provides is few, and foundry goods cooling velocity is fast, the production cycle shortens.
7) highly versatile: the sandbox using in moulding is the middle special shape mo(u)lding box that uses this utility model, and other use all purpose flask, strengthen versatility.
