Abstract
The utility model relates to a clamp plate for increasing the rigidity of a casting sand box, wherein the sand box is clamped by two clamp plates. The clamp plates are arranged oppositely, reinforcing vertical plates are distributed on the clamp plates, a plurality of exhaust holes are arranged between the reinforcing vertical plates, bolt holes are distributed on the outlines of the clamp plates, and the clamp plates are linked with the sand box by bolts. Due to the adoption of the clamp plate for increasing the rigidity of the casting sand box, the rigidity of the prior casting sand box which is newly manufactured is increased, mould sand is avoided escaping outwards from a crossbar under the expansion action of cast iron, and the graphited expansion of the cast iron is effectively utilized, thereby a complete casting product is obtained.
Description
Technical field
The utility model relates to metallurgical casting, particularly a kind of firm type clamping plate of increasing of sandbox of casting.
Background technology
The casting sandbox that at present general casting producer uses when sand casting mostly is welding structural element or foundry goods, in ironcasting especially nodular iron casting is produced often because the sandbox insufficient rigidity, molding sand is escaped from case band portion by the cast iron expansion in the cooling procedure, make the graphitization expansion of cast iron can not get effectively utilizing and cause defective such as foundry goods shrinkage porosite, when serious foundry goods will be scrapped.Owing to be subjected to the restriction of existing casting frock and the limit of manufacturing cost, caused above-mentioned situation in actual production, to take place often.
How to improve above-mentioned situation, make that the graphitization expansion of cast iron is effectively utilized, and have economy, demonstrate it in determining foundry technology process and improve importance aspect the casting quality, this is that pendulum is in a casting producer problem in front.
The utility model content
Task of the present utility model provides a kind of casting sandbox and increases firm clamping plate, and it has solved present casting producer used casting sandbox when sand casting and has caused the foundry goods shrinkage porosite because of insufficient rigidity, the problem that causes foundry goods to be scrapped when serious.
Technical solution of the present utility model is as follows:
A kind of casting sandbox increases firm clamping plate, is wherein accompanied sandbox, and described clamping plate are two clamping plate of putting relatively, be laid with the reinforcement riser on the clamping plate, strengthening being provided with several steam vents between the riser, lay bolt hole in the clamping plate gabarit, pass through bolted on connection between clamping plate and the sandbox.
Adopt casting sandbox of the present utility model to increase firm clamping plate, can make the casting sandbox of existing and coming of new strengthen rigidity, prevent that molding sand is escaped from case band portion by the cast iron expansion, the graphitization expansion of cast iron is effectively utilized, thus the foundry goods that obtains perfecting.
Description of drawings
Fig. 1 is a kind of main TV structure schematic diagram that sandbox increases firm clamping plate of casting of the present utility model.
Fig. 2 is that Fig. 1 casts the right TV structure schematic diagram that sandbox increases firm clamping plate.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is that a kind of casting sandbox increases firm clamping plate, is wherein accompanied sandbox 5.
Described clamping plate 1 are two clamping plate of putting relatively, are laid with on the clamping plate 1 to strengthen riser 2, are strengthening being provided with many steam vents 4 between the riser 2.Lay bolt hole in clamping plate 1 gabarit, connect by bolt 3 between clamping plate 1 and the sandbox 5.
On clamping plate 1, can lay as required water, the rising head through hole, its size can according to the casting sandbox size determine.Operation was comparatively convenient when clamping plate 1 contour dimension was identical with sandbox 5 contour dimensions.When clamping plate 1 contour dimension during, adopt stay bolt directly to connect two clamping plate greater than sandbox 5 contour dimensions.
As shown in FIG., strengthening riser 2 is frame type structures.Also can be arranged to crisscross type structure (not shown) with strengthening riser 2.
When mould assembling, use these clamping plate, increase firm clamping plate with two and connect firmly mould assembling again with the upper and lower case case of casting sandbox back-packing is blue respectively with bolt.Like this, utilize to increase the mobile variation that firm clamping plate have limited the sandbox wall, molding sand is enclosed in the obturator simultaneously, stoped moving and escaping of molding sand, thereby make the sand mold after the mould assembling constitute obturator, strengthened the rigidity of casting mold greatly from case band portion.In addition, make the gas of sand mold escape by the steam vent that is distributed on the clamping plate, the gas permeability of casting mold is protected.
When mould assembling, use these clamping plate, do not produce any influence for each procedure of the moulding before the mould assembling.
Casting sandbox of the present utility model increases firm splint material can adopt steel welding construction spare or foundry goods.Utilize this casting sandbox to increase firm clamping plate, especially, have more its use value for spheroidal graphite cast-iron production and the horizontal upright casting forging type of doing.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
