Abstract
The utility model discloses a kind of six cylinder exhaust manifold casting sand cores, comprise core body, the airway core place of described core body is provided with the core bar connecting each airway core, and one end that described core bar is connected with airway core in the middle of exhaust manifold is provided with lengthening pellet.Have effectively achieved, by lengthening pellet, effective support limit is carried out to two parts core, thus the centre distance of two airway cores is stablized in the middle of guarantee exhaust manifold, improve production efficiency and the quality of production of exhaust manifold, avoid coordinating of core and molding sand simultaneously, reduce drop, improve product appearance quality, percent defective is greatly reduced.
Description
Technical field
The utility model relates in blast pipe casting process and uses core technical field, particularly relates to a kind of six cylinder exhaust manifold casting sand cores.
Background technology
In the foundry production of six cylinder exhaust manifolds, because exhaust manifold is symmetrical structure, in order to save die cost, when designing production mould, only need mold half to produce core, to become as a whole by core composite assembly between two again, the production moulding by casting of whole exhaust manifold can be completed.But, tradition core only has the half of exhaust manifold, three air inlet road junctions are wherein connected by core bar by place, therefore, when casting sand core is arranged in die cavity, lack detent mechanism between the two air inlet road junctions due to two halves exhaust manifold adjacent, often cause the air inlet road junction, two, centre of six cylinder exhaust manifolds namely in the middle of the centre distance size of two cylinders unstable, to the great inconvenience of follow-up punching and exhaust manifold mounting strap.And dimensional discrepancy is excessive, directly cause scrapping of exhaust manifold, have a strong impact on production efficiency and exhaust manifold product quality.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, a kind of six cylinder exhaust manifold casting sand cores are provided, structure is simple, easy and simple to handle, when not changing former casting mould, effectively ensure the stable of the middle two cylinder centre-to-centre spacing sizes of six cylinder exhaust manifolds, and avoid core to coordinate with molding sand, reduce drop, effectively improve product quality, reduce percent defective.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of six cylinder exhaust manifold casting sand cores, comprise core body, the airway core place of described core body is provided with the core bar connecting each airway core, and one end that described core bar is connected with airway core in the middle of exhaust manifold is provided with lengthening pellet.
Frozen iron blocks is provided with in described pellet.
Describedly iron block will be provided with the threaded screw rod passed from described pellet side, described threaded screw rod is arranged the female adjusting sleeve pipe of tool.
The utility model is by the core bar medial extremity at six cylinder exhaust manifold casting sand cores, the middle air flue place end of i.e. exhaust manifold arranges lengthening pellet, have effectively achieved, by lengthening pellet, effective support limit is carried out to two parts core, thus the centre distance of two airway cores is stablized in the middle of guarantee exhaust manifold, improve the production efficiency of exhaust manifold and the quality of production, avoid coordinating of core and molding sand, minimizing drop simultaneously, improve product appearance quality, percent defective is greatly reduced.By arranging frozen iron blocks in pellet, can further improve the moulding by casting quality of middle two gas ports, avoiding occurring shrinkage porosite phenomenon, improving road junction ratio of briquetting.Further, by arranging the threaded screw rod passed from pellet side on iron block, and adjusting sleeve pipe is set on threaded screw rod, thus effectively realize regulating distance between two parts exhaust manifold core bar by threaded screw rod and adjusting sleeve pipe, avoid the situation of airway core range deviation in the middle of the exhaust manifold that causes due to pellet dimensional defects to occur.The utility model is easy, practical, cost is low, when not changing original production mould and core, efficiently solve the problem of two cylinder centre distance size instability in the middle of six cylinder exhaust manifolds, with lower cost and change, achieve larger technological progress, effectively improve the quality of product, significantly reduce percent defective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of the utility model when not arranging pellet;
Fig. 2 is the structural representation of the utility model when arranging pellet;
Fig. 3 is the structural representation that the utility model pellet connects.
Detailed description of the invention
Embodiment one
As Fig. 1, shown in Fig. 2: a kind of six cylinder exhaust manifold casting sand cores, comprise core body 1, airway core 2 place of described core body 1 is provided with the core bar 3 connecting each airway core 2, one end that described core bar 3 is connected with airway core in the middle of exhaust manifold is provided with and lengthens pellet 4, described lengthening pellet 4 is pasted on described core bar 3, the length of the pellet 4 that core bar 3 end is arranged is the half of two parts core body latter two core bar 3 spacing assembled of exhaust manifold, realize between assembled rear core bar stablize spacing, thus the middle two cylinder centre-to-centre spacing sizes of effective guarantee six cylinder exhaust manifold is stable.
Embodiment two
As shown in Figure 3: the difference of the present embodiment and embodiment one ground in: be provided with frozen iron blocks 7 in described pellet 4.Describedly iron block 7 will be provided with the threaded screw rod 6 passed from described pellet 4 side, described threaded screw rod 6 is arranged the female adjusting sleeve pipe 5 of tool.Frozen iron blocks 7 is placed in mould when penetrating sand product pellet 4 by threaded screw rod 6, and threaded screw rod 6 is threaded with described frozen iron blocks 7 or is directly welded in described frozen iron blocks 7.Screw thread in threaded sleeve 5 is half plus thread half left-hand thread, is realized the adjustment of pellet 4 spacing between the threaded screw rod 6 of two pellets 4 by adjusting sleeve pipe 5.The present embodiment by arranging frozen iron blocks 7 in pellet 4, and on the one hand, in the middle of can realizing when pouring into a mould, the quick cooling at gas port place, avoids occurring shrinkage porosite phenomenon, improve road junction ratio of briquetting.On the other hand, conveniently threaded screw rod 6 is set on core port 4, and by the adjusting sleeve pipe on threaded screw rod, distance fine regulation is carried out to the pellet between core bar, ensure the stable distance between core bar, efficiently solve the problem of two cylinder centre distance size instability in the middle of six cylinder exhaust manifolds.
