Abstract
The utility model discloses a casting of V method combines casting structure with disappearance mould, including U type foundry goods, this U type foundry goods has left side wall and right side wall, forms the opening between left side wall and the right side wall, sets up horizontal lacing wire on the opening, this horizontal lacing wire and left side wall and the inboard lug connection of right side wall, this horizontal lacing wire contains spacer bar and foam lacing wire, and the foam lacing wire is connected in the spacer bar, and whole horizontal lacing wire is connected with left side wall and right side wall through the spacer bar. The spacer bar is fixed in through the winding of EVA film to this foam lacing wire. This foam lacing wire cross section is square, rectangle, ellipse, trapezoidal or circular. The utility model discloses, make deformations problems obtain better solution, reduced the product defective rate.
Description
Technical field
The relevant casting field of the utility model, particularly a kind of V method cast the casting structure being combined with disappearance mould.
Background technology
The casting of V method and lost foam casting have a lot of something in common: all select dry sand filling, all with vibration ramming, adopt plastic seal sandbox, vacuum suction curable type and negative pressure cast.
V method casting advantage is distinct, and its drawback is also very outstanding: the limitation being 1. subject to film extension property, and the casting of V method is not suitable for producing the part of complex contour; 2. vacuum system needs to be connected with sand mold at any time.
Lost foam casting process has clear superiority, both can produce the foundry goods of complex contour, can produce again inner chamber intricate casting. Compared with resin sand technique, it is more many that lost foam casting replaces core, and its profit margin is more big. But its drawback is also very important, the surface quality of continuous castings that disappearance mould is produced and material capability are subject to the impact of Foam Pattern gasification cracking product and worsen, and cause the problem such as Iron Casting Surface carbon defects and steel casting carburetting. Therefore material is required high foundry goods (part of especially ensuring public security) and middle low carbon steel part, lost foam process should not be selected; Lost foam casting produces the dull and stereotyped like members of thin-walled, the difficult control of its size distortion.
To sum up, the casting of V method is applicable to medium-and-large-sized simple foundry goods, and lost foam casting is applicable to middle-size and small-size inner chamber intricate casting.
Practical novel content
The problem that the utility model solves is to provide a kind of in conjunction with the Novel casting structure of the casting of V method and lost foam casting.
The technical solution of the utility model is: a kind of V method is cast with disappearance mould in conjunction with casting structure, it is characterised in that, comprise U-shaped foundry goods, this U-shaped foundry goods has left side wall and right side wall, forms opening between left side wall and right side wall, and opening arranges horizontal lacing wire; This transverse direction lacing wire and left side wall and right side wall inside straight connect in succession, and this transverse direction lacing wire comprises and supports reinforcing bar and foam lacing wire, and foam lacing wire is connected to support reinforcing bar, and by supporting, reinforcing bar is connected with right side wall with left side wall in whole horizontal lacing wire.
This foam lacing wire is fastened in support reinforcing bar by eva film.
This foam lacing wire cross section is square, rectangle, ellipse, trapezoidal or circular.
The useful effect that the utility model reaches is: utilize this horizontal disappearance mould lacing wire, can effectively solve the deformation problems at this kind of foundry goods opening place, problem on deformation better be solved, reduces product cost, especially to the U shaped cast part that cannot directly arrange lacing wire, effect is more obvious.Overproof by about 70% original casting deformation amount, drop to about 2%, problem on deformation is better solved, reduce product fraction defective.

Fig. 2 is the structural representation supporting reinforcing bar and foam lacing wire combination.
Fig. 3 is the cross-sectional view of Fig. 2.
Embodiment
As shown in Figure 1A, B, 2,3, Figure 1A, B are two kinds of common U-shaped foundry goods. A kind of V method casting of the utility model in conjunction with casting structure, comprises U-shaped foundry goods 1 with disappearance mould, and this U-shaped foundry goods 1 has left side wall 2 and right side wall 3, forms opening 4 between left side wall 1 and right side wall 3, and opening 4 arranges horizontal lacing wire 5; This transverse direction lacing wire 5 connects in succession with left side wall 3 and right side wall 4 inside straight, and this transverse direction lacing wire 5 comprises support reinforcing bar 6 and foam lacing wire 7, and foam lacing wire 7 is connected to and supports reinforcing bar 6, and by supporting, reinforcing bar 6 is connected 3 with left side wall 2 with right side wall in whole horizontal lacing wire 5.
This foam lacing wire 7 can be fastened in support reinforcing bar 6 by eva film 8. This foam lacing wire 7 cross section can be square, rectangle, ellipse, trapezoidal or circular, certainly, it is also possible to adopt other shapes according to demand.
Utilize this horizontal lacing wire structure, it is possible to effectively solving the deformation problems at this kind of foundry goods opening place, problem on deformation is better solved, reduces product cost, especially to big uncork foundry goods, effect is more obvious.
In the specific embodiment of Fig. 2 and Fig. 3, foam lacing wire specification is 60 × 60 × 1300mm, support reinforcing bar is 6 × 1400mm, support reinforcing bar and foam lacing wire are fastening by V method casting adhesive tape, then it is wound around the fastening good foam lacing wire of parcel with eva film, when foundry goods moulding, after waiting mould overlay film to complete, foam lacing wire two ends is fixed on the corresponding position of mould, on mould, foam lacing wire fixed position must be clean, starts normal moulding after fixing. When being poured into a mould by product after moulding, when building, under the heat effect of liquid metal, foam lacing wire generation pyrolytic gasification, liquid metal constantly occupies foam lacing wire position, and final formation lacing wire and foundry goods are combined as a whole.
Certainly, the cross section of foam lacing wire can also adopt ellipse, trapezoidal, circular or other irregular shapes. (herein for simple to operate when rectangle mainly makes disappearance mould lacing wire).
Utilize this horizontal disappearance mould lacing wire, it is possible to effectively solving the deformation problems at this kind of foundry goods opening place, problem on deformation is better solved, reduces product cost, especially to the U shaped cast part that cannot directly arrange lacing wire, effect is more obvious.
