Description

The swage sand mo(u)ld

Technical field

The utility model belongs to casting technology field, is specifically related to the swage sand mo(u)ld of a kind of automatic sand casting system.

Background technology

Casting is a kind of comparatively economic blank formation method, particularly for the part of complexity, more can demonstrate its economy.The scope of application of the size of mo(u)lded piece, shape, weight is very wide, and therefore, in machinery manufacturing industry, Foundry Production blank part is topmost mode, and it is one of basic link very important in all kinds of machineries and the equipment industry industrial chain.But foundry production can produce dust, pernicious gas, noise etc., has a strong impact on environment; In addition, foundry industry belongs to labor-intensive production, and labour intensity is large, production efficiency is low.

The method of casting has a lot, and sand casting is wherein a kind of, and the production process of sand casting roughly is divided into following components:

One, core is made in moulding

It is according to the casting technique requirement that core is made in moulding, and it is finished determining that formative method is technical.The economic effect of the precision of foundry goods and whole production processes depends primarily on this end production process.Make the core process for moulding, basically all realized at present mechanization or automation.Sand mold moulding core-making installation commonly used has high, medium and low moulding machine, sand throwing machine, box-less shoot squeeze molding machine of case, core shooter etc.

Two, matched moulds

After making core and finishing, it next is matched moulds.This part is mainly added manually by machinery finishes.For some large-scale foundry goods, the labour intensity of this process is large, production efficiency is low.

Three, cast

Cast is smelt the liquid metal with certain chemical composition with Metal Melting with exactlying, is injected in the casting mold that first two steps finish the process of acquisition part blank after cooling under Action of Gravity Field.Casting process has determined the quality of the part blank that waters, and affects the quality of final products.For this technical process, also there are at present some scientific research institutions, universities and colleges etc. to work out Auto-pouring System, experiment type.But in actual applications, this type of running gate system that occurs at present, or manually being cast for the master, it is made analysis-by-synthesis, accurately judges information such as the various physical quantitys of system such as temperature, color, position, flow, speed, pressure by experienced operator, to obtain best cast effect.When with regard to this point, also do not have to replace artificial high-tech automatic pouring machine at present and come out.

Four, divide the mould knockout

Minute mould sand that falls is the technique that operating condition is arduouser, substantially all is at present artificial or adopts mechanical assistance half artificial mode to finish.

Comprehensive present casting production process, can find: in certain link of Foundry Production, there has been automated mechanical equipment to finish certain technical process in the casting process, to enhance productivity, and reduction labour intensity, but the turnover between the links of Foundry Production overall process is connected, or realizes by artificial or half artificial mode.

In sum, the residing state of casting production process is at present: whole foundry production is not realized Based Intelligent Control, realizes completely automated production, and its production efficiency is still low, and labour intensity is very large; Foundry Production still belongs to the labor-intensive production of low technical.

The utility model relates to the swage sand mo(u)ld of a kind of automatic sand casting system.

Summary of the invention

The utility model discloses the swage sand mo(u)ld of a kind of automatic sand casting system.

The utility model is taked following technical scheme: the swage sand mo(u)ld, formed by patrix and counterdie matched moulds, and the inner die cavity that forms, upper wall and/or the lower wall of swage sand mo(u)ld have through hole, and through hole communicates with the die cavity of inside; The two side of patrix forms elongated slot along its length, and each elongated slot is the banding plate fixedly, and the patrix sidewall corresponding with the banding plate forms locating slot along short transverse, and locating slot extends to upper surface and the bottom surface of patrix; The external structure of described counterdie and the external structure of patrix are symmetrical, stretch into the patrix locating slot corresponding with counterdie and screw corresponding banding plate and banding patrix and counterdie by bolt.

Described swage sand mo(u)ld, the both ends of the surface of patrix respectively form an end ear, the end ear axially have a square hole.

Described swage sand mo(u)ld, the both ends of the surface of counterdie respectively form an end ear, the end ear axially have a square hole.

Described swage sand mo(u)ld, each elongated slot are inserted two or four blocks of banding plates, and the banding plate is fixed in patrix or counterdie by screw.

Described swage sand mo(u)ld, four jiaos of patrix respectively form a matched moulds dowel hole, corresponding, and four jiaos of counterdie also respectively form a matched moulds dowel hole, and the patrix matched moulds dowel hole corresponding with counterdie is in order to embed the matched moulds guide pin bushing.

Adopt the automatic sand casting system of the utility model swage sand mo(u)ld, it has the advantages such as production efficiency is high, action required workman is few, labour intensity is low.

The specific embodiment

Below in conjunction with accompanying drawing the utility model preferred embodiment is described in detail.

Referring to Fig. 1-3, swage sand mo(u)ld 1 by patrix 1-1 and counterdie 1-2 up and down relative covering form, patrix 1-1 is identical with the external structure of counterdie 1-2, the below describes the external structure (external structure of counterdie is with reference to patrix) of patrix 1-1 in detail: patrix 1-1 is and is not with the rectangular-shaped of bottom surface, has die cavity, its upper wall offers some through hole 1-1-1, through hole can be used as respectively to penetrate sand, casting, top sand etc., certainly each hole site and size are offered according to the concrete condition of made workpiece, and the present embodiment only is the signal explanation.The two side of patrix forms elongated slot 1-1-5 along its length, and each elongated slot is inserted four banding plate 1-1-2, and the banding plate is fixed in patrix by screw.Certainly, according to concrete needs, same elongated slot selects two blocks of banding plates also can.The patrix sidewall corresponding with the banding plate forms locating slot 1-1-7 along short transverse, and this locating slot extends to upper surface and the bottom surface of patrix.The both ends of the surface of patrix (broad ways) respectively form a cylindrical end ear 1-1-3, axially have a square hole 1-1-6 along each end ear.Four jiaos of patrix respectively form a matched moulds dowel hole 1-1-4, in order to embed matched moulds guide pin bushing 1-3.

The die cavity of upper and lower mould is covered up and down relatively, both inside has formed the die cavity of swage sand mo(u)ld, inserting the alignment pin (not shown) in both four corresponding matched moulds guide pin bushings locates upper and lower mould, after upper and lower mould covers, both stretch into by locating slot 1-1-7 respectively by several hex bolts 1-4 again, and screwing banding plate corresponding to upper and lower mould and banding, the present embodiment is selected four hex bolts, each two of both sides.Take out alignment pin after the upper and lower mould locking.

Those of ordinary skill in the art will be appreciated that, the utility model is not limited to above-described embodiment, any conversion of the present utility model, modification all fallen into protection domain of the present utility model.
