Abstract
The invention relates to an air outlet box for casting and particularly relates to a winding type air outlet box for casting. The air outlet box comprises a box body; an air outlet rod is matched at the top of one side of the box body; and the lower part of a cross section of the box body is rectangular, and the upper part of the cross section of the box body is Z-shaped. The air outlet box provided by the invention has the advantages of simple structure, convenience in manufacture and cost-saving property; and the problems of influencing casting quality and cost waste, caused by that loose sand falls into a cavity in an air outlet hole paving process, can be solved.
Description
Technical field
The present invention relates to a kind of casting with going out the vapour case, especially relate to a kind of casting and go out the vapour case with meander configuration.
Background technology
Large-scale steel-casting owing to all comprise a certain amount of gas in the molten steel, therefore, in the process of building, need be guided out gas in the die cavity through pore in casting process.Guiding freely can not produce defectives such as the fire of choking, pore.In order to guarantee to obtain the second best in quality foundry goods, in the modeling process, the operator can design steam vent in advance above blind riser.It is that the operator directly uses earthenware above blind riser, to be directed to outside the sandbox in modeling process that tradition lays out the steam vent mode.There is following problem in this kind method: when 1) using; The operator adopts porcelain tube directly to be routed to the sandbox top from the blind riser top, makes in this way, in the operating process; Easily loose sand is dropped in die cavity, the blind riser; Be difficult for cleaning out, cause foundry goods to produce the burning into sand defective, cause foundry goods to be scrapped when serious; When 2) using conventional method to lay, the operator will be docked porcelain tube at any time, needs to use the adhesive tape adhesion.Cause in the modeling process inefficiency; Use the porcelain tube paving mode, behind the casting pouring, porcelain tube all damages, and can not recycle, and causes very big cost waste.Also do not overcome at present the device of this problem.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of simple in structure, easily manufactured, practice thrift cost, can solve that loose sand falls into die cavity in the vapor opening process of deployment, the casting that influence casting quality, cost and waste problem goes out the vapour case with meander configuration.
The present invention realizes in the following manner:
A kind of casting goes out the vapour case with meander configuration, it is characterized in that: it comprises a casing, and the top of casing one side is combined with out the vapour rod;
The bottom, longitudinal section of said casing is that rectangle, top are the Z font;
The said cross section that goes out the vapour rod is a hexagon.
The present invention has following effect:
1) simple in structure, easily manufactured, practice thrift cost: provided by the inventionly go out the vapour case and comprise that two parts hexagon goes out the vapour rod and goes out the vapour casing,, prepare the vapour casing earlier, directly use silica sand, do not need specially treated in the moulding preparatory stage.The fuse degree of packing meets the casting mold conventional criteria, mustn't special demands, need not brush, spray treatment; The vapour case that goes out for preparing is positioned over the corresponding venthole of blind riser place, hexagon is gone out the vapour rod insert out in the vapour upper box part venthole, carry out filling moulding; Moulding is extracted out the vapour rod out from top box after accomplishing.
2) improved operating efficiency, save production cost: device provided by the invention goes out vapour rod to be used, and does not need special processing in the modeling process, and the loose sand that has caused when having reduced porcelain tube butt joint on the traditional handicraft falls into the probability of steam vent; Improved operating efficiency simultaneously; Go out the vapour rod after vapor opening is accomplished in preparation, extract out, can be repeatedly used by the top box place.Save production cost.
3) going out the vapour case and use, is that the Z font structure is arranged owing to go out the vapour case, can avoid in the modeling process, and loose sand falls into rising head, has guaranteed the cleannes of die cavity fully.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The structural representation that Fig. 2 uses for the present invention.
The specific embodiment
A kind of casting goes out the vapour case with meander configuration, and is as shown in Figure 1: it comprises a casing 1, and the top of casing 1 one sides is combined with out vapour rod 2;
The bottom, longitudinal section of said casing 1 is that rectangle, top are the Z font;
The said cross section that goes out vapour rod 2 is a hexagon.
As shown in Figure 2: vapour case 1 is positioned over blind riser 3 corresponding venthole places and apperance 4 is joined for going out of will preparing, and hexagon is gone out vapour rod 2 insert out in the vapour case 1 top venthole, carries out filling moulding; Moulding is extracted out the vapour rod out from top box after accomplishing.
Claims (3)
1. a casting goes out the vapour case with meander configuration, it is characterized in that: it comprises a casing (1), and the top of casing (1) one side is combined with out vapour rod (2).
2. casting as claimed in claim 1 goes out the vapour case with meander configuration, it is characterized in that: the bottom, longitudinal section of said casing (1) is that rectangle, top are the Z font.
