Will the utility model relates to a sand-saving device places in sand mould die cavity to the molding sand of effectual saving, simultaneously the utility model discloses although inside isolated molding sand gets into the body, the air still can circulate, thereby has guaranteed that sand-saving device can not damage because of inside pressure variation, has improved sand-saving device's life.
Description
Technical field
The utility model relates to sand casting technical field, specifically for the joint sand device of energy-saving sand, is particularly suitable for foundry's energy-saving sand in the time of moulding of single-piece, small lot, many kinds.
Background technology
At present, foundry is all considering to use how in large quantities joint sand device in order to save cost, can make specially suitable joint sand mold sandbox and reduce the consumption of molding sand for large foundry goods in batches, and for single-piece, small lot, the foundry goods of many kinds, due to the size of each foundry goods, shape, weight is not identical, under this complicated situation requirement easily and effectively energy-saving sand be a difficult point, in prior art, there is employing steel ball (Chinese patent " casting sand-saving steel ball ", Granted publication CN201644704U, November 24 2010 Granted publication day), also there is the steel ball structure that adopts hollow type.Adopt the structure of hollow type, enter sand in order to prevent from saving in sand device, when the welding of joint sand device, require its good seal performance, meanwhile, because the gas in joint sand device drops to normal temperature, reusable joint sand device again from normal temperature rising degree more than 1,000, through continuous variations in temperature repeatedly, most several sections of sand device all can deform and damage, and has affected joint sand device service life, has more seriously reduced employee and use the enthusiasm of joint sand device.Especially pour into casting mold at molten iron, be incubated, be cooled in shake out overall process, can not make its distortion because of the volume of air in joint sand device and pressure variation.
Utility model content
For the deficiency in background technology, the purpose of this utility model is to provide a kind of foundry in single-piece, small lot, many kinds can be easy to use, effective, and the joint sand device of the minimizing moulding sand consumption of can reuse, the life-span is long, this joint sand device also has respiratory function simultaneously, and can adopt the similar mode playing with building blocks to use.
The technical solution adopted in the utility model is: joint sand device, is characterized in that: comprise tubular type body, described body outer wall connects at least two pack supports; Described body two ends are provided with sealing plate; Described sealing plate is provided with breather pipe, and described breather pipe is positioned at described body; In described breather pipe, establish bulk wire; Described breather pipe is provided with and prevents that wire from slipping into the block of body interior near the one end at body center.
Like this, adopt hollow design, block can prevent that wire from slipping into body interior simultaneously, and like this, not only isolated molding sand enters in body, and has the effect of breathing, improves service life.。
Further, described breather pipe distance compare Yuan one end, described body center is provided with baffle plate, and described baffle plate is provided with the first passage.
Further, described baffle plate is provided with pressing plate, and described pressing plate is provided with the second passage; Between described baffle plate and pressing plate, be provided with the first steel wire.
Again further, between described the first steel wire and baffle plate, be provided with the second steel wire, the density of described the second steel wire is greater than the density of described the first steel wire.
Further, described support is positive n limit shape, n >=3, and described support is cut in described body outward.Like this, be conducive to piling up of body, played the effect that prevents body distortion simultaneously.
Further, n=4.
Further, the axis of described breather pipe and the axis coaxle of described body.Like this, can there is better ventilatory effect.
The beneficial effects of the utility model are: the joint sand device of the utility model design is placed in sand mold die cavity, thereby the molding sand of effectively saving, although the isolated molding sand of the utility model enters body interior simultaneously, but air still can circulate, thereby ensure that joint sand device can not damage because inner pressure changes, improved the service life of joint sand device.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks schematic diagram;
Fig. 2 is that schematic diagram is looked on a left side of the present utility model;
Fig. 3 is the enlarged diagram at A place in Fig. 1.
In figure: body 1, support 2, sealing plate 3, breather pipe 4, baffle plate 5, pressing plate 6, the first passage 7, the first steel wire 8, wire 9, block 10, the second steel wire 11, the second passage 12.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the joint sand device of the utility model design, comprises tubular type body 1, and described body 1 outer wall connects at least two pack supports 2, and described support 2 is positive n limit shape, n >=3, and outside described support 2, be cut in described body 1; Preferably, the cross section of the present embodiment medium-height trestle 2 adopts n=4, that is to say that the cross section of support 2 is square, and is cut in described body 1 outside described square rack 2, like this, is conducive to piling up of body, has played the effect that prevents body distortion simultaneously.Described body 1 two ends are provided with sealing plate 3; Described sealing plate 3 is provided with the breather pipe 4 coaxial with described body 1, and described breather pipe 4 is positioned at described body 1, and coaxial design can obtain better ventilatory effect, and namely respiratory function is stronger; In described breather pipe 4, establish bulk wire 9, described breather pipe 4 is provided with block 10 near the one end at body 1 center, and like this, isolated molding sand enters in body, prevents that wire 9 from slipping in body.Further, described breather pipe 4 distance described body 1 compare Yuan one end, center are provided with baffle plate 5, and baffle plate 5 is provided with the first passage 7; Described baffle plate 5 is provided with pressing plate 6, and described pressing plate 6 is provided with the second passage 7; Between described baffle plate 5 and pressing plate 6, be provided with the first steel wire 8.Further, between described the first steel wire 8 and baffle plate 5, be provided with the second steel wire 11, the density of described the second steel wire 11 is greater than the density of described the first steel wire 8, and in the present embodiment, the first steel wire adopts 60 object steel wires, and the second steel wire adopts 120 object steel wires.When use, the first passage 6 and the second passage 7 need be alignd.Further, the diameter of described the second passage 7 is not less than the diameter of the first passage 6.
Block 10 can be a rod-like element, can be also many parallel rod-like element, and these rod-like element are connected with breather pipe 4 one end, prevents that wire 9 from skidding off from breather pipe 4, and slip into body 1 inside thereby reach.Certainly block 10 also can adopt other version, for example: the rod-like element Crossware of M shape, cross, well word, these structure with there being difference, but its objective is unanimously, just do not enumerate at this.
In the time of moulding, model, sandbox are put well to rear elder generation and carry out moulding according to normal formative technology, after the molding sand of model has covered under the guaranteed prerequisite of mold thickness, can singly joint sand device of the present utility model be placed on to die cavity inside as required, place how many joint sand devices and be just equal to the molding sand of having saved same volume, it should be noted that the intensity in order to ensure sand mold, between joint sand device, require to have 50 millimeters of above gaps.In use, support can prevent the distortion of body, improves service life.
After finishing using, will save sand device and take out from sandbox, and utilize polygon support to have and can easily joint sand device be piled up together, its process of piling up is similar to and plays with building blocks equally.
