Abstract
The utility model discloses a flask with guidance and location. The flask with guidance and location comprises an upper flask and an under flask. A conical locating-lock is arranged on both sides of the under flask. A fixing pin and a guiding pin combining by inserted-connected with the conical locating-lock are arranged on both sides of the upper flask respectively. The shape of section of the fixing pin is waist like ring. The shape of section of the guiding pin is ring. The conical locating-lock with the special shape and slope forms a reliable relationship of combining by guiding inserted-connected with the fixing pin and the guiding pin. The upper flask and the under flask with deviation between them are guided step by step to the correct position to realize closing with high precision by using dead weight and pin of the upper flask said, so we can ensure the size precision of casting, avoid producing defect like mold shift and distortion. The utility model has the advantages of simple structure and operating conveniently, and is very suitable for closing location of the upper flask and the under flask of large casting. The utility model also can be used in the location between the objects which have relative position requirements.
Description
Technical field
The utility model relates to the sandbox that mainly is applicable to heavy castings, refers to a kind of guiding locate mode sandbox particularly.
Background technology
China is Foundry Production big country, and foundry goods production capacity output all occupies first place in the world.With regard to formative method, most foundry goods all adopt box moulding, no matter are two-part mo(u)lding or three-cavity moulding, and the problem of individual mould assembling location is all arranged.Large-scale, complicated foundry goods, its mould assembling location more shows crucial.At present, the mould assembling location of the upper and lower sandbox of Chinese large-sized foundry goods is adopted artificial naked eyes contraposition mostly, common apparatus auxiliary operation, because factors such as the size of the upper and lower sandbox of heavy castings is big, weight big, hoist lifting hook swing, mould assembling location is difficulty comparatively, very easily produces upper and lower sandbox and squeezes and bump, get rid of situations such as head, mould shift, has both delayed production, influence casting dimension accuracy again, even cause that easily foundry goods scraps.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of simple in structure, operation is convenient, mould assembling accurately, be suitable for the guiding locate mode sandbox of heavy castings.
For achieving the above object, the guiding locate mode sandbox that the utility model is designed, comprise cope and drag box, be respectively arranged with a conical dowel pin on the dual-side of described drag box, be respectively arranged with the corresponding fixedly guide and the guiding guide of pegging graft and cooperating on the dual-side of described cope with described conical dowel pin.Wherein, the cross section of described fixedly guide is the oval annular, and the lateral clearance between itself and the conical dowel pin is less, the axial clearance is big slightly, can prevent that upper and lower sandbox from excessively departing from, and plays fixation between upper and lower sandbox.The cross section of described guiding guide is annular, it is relative with the gap between the conical dowel pin big, and gap length is identical all around, so it allows that certain departing from arranged between the upper and lower sandbox, has avoided upper and lower sandbox before the mould assembling to block the generation of a situation that can not fall.Along with the carrying out of mould assembling process, conical dowel pin and fixedly guide, the gap of guiding between the guide are more and more littler utilizes the break-in effect of pin and cover, the upper and lower sandbox that departs from can be directed on the correct position gradually.
Thereby, advantage of the present utility model is: designed conical dowel pin is with its special shape and gradient, and fixedly form the matching relationship of guiding grafting reliably between guide, the guiding guide, utilize the deadweight of cope and bearing pin, guide break-in principle, upper and lower sandbox devious progressively can be directed into correct position, the mould assembling of final realization high accuracy, thereby the dimensional accuracy of assurance foundry goods prevent that foundry goods from producing defectives such as mould shift, distortion.Simultaneously, the utility model is simple in structure, and operation is convenient, only adopts common metal materials processing to make, and cost of manufacture is low, can increase substantially production efficiency.Be very suitable for the mould assembling location of the upper and lower sandbox of heavy castings, also can be diverted between other objects that relative position requirement is arranged and locate.
Description of drawings
Fig. 1 is a kind of structural representation of guiding the locate mode sandbox;
Fig. 2 is an A-A sectional structure schematic diagram among Fig. 1;
Fig. 3 is a B-B sectional structure schematic diagram among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Guiding locate mode sandbox shown in the figure is made up of cope 1 and drag box 5.Be separately installed with a conical dowel pin 2 on the dual-side of drag box 5, conical dowel pin 2 is removably to be embedded in the embedding mouth of drag box 5 dual-sides, on the movable supporting plate 6 of its bottom support in this embedding mouth, cope 1 falls and can take movable supporting plate 6 away behind the position, dismounting inferior pyramidal alignment pin 2.Be separately installed with the fixedly guide 3 and the guiding guide 4 of pegging graft and cooperating with conical dowel pin 2 on the dual-side of cope 1, fixedly guide 3 and guiding guide 4 are fixedly to be embedded in the cope 1 dual-side embedding mouth.Conical dowel pin 2 is made of upper and lower two sections awl posts, and the gradient of its hypomere awl post is greater than the pattern draft of sandbox model, and the gradient of its epimere awl post is greater than the gradient of hypomere awl post, so that fixedly guide 3 can successfully insert and locate with guiding guide 4.Fixedly the cross section of guide 3 is the oval annular, and the cross section of guiding guide 4 is annular, and it acts on as previously mentioned, no longer repeats therewith.
The radial dimension of conical dowel pin 2 can determine that length dimension is then determined according to the profile overall dimension of sandbox according to the weight of sandbox.Because conical dowel pin 2 loads are bigger, and always with fixedly guide 3 and 4 frictions of guiding guide, so require to choose the bigger steel alloy of rigidity or high-carbon steel materials processing is made, and carry out the surface hardening processing.Fixedly guide 3 and guiding guide 4 are to consume consumable accessory, need periodic replacement.
When cope 1 and drag box 5 mould assembling, respectively conical dowel pin 2 is embedded in the embedding mouth of drag box 5 dual-sides, guiding cope 1 falls behind the position, takes out out movable supporting plate 6, takes out conical dowel pin 2 and gets final product.Fixedly the installation of guide 3 and guiding guide 4 then is after cope 1 and drag box 5 apolegamys finish, and is fixed in the cope 1 dual-side embedding mouth, and fixing means can adopt irritates lead or spot welding.
