Abstract

The utility model relates to a casting process field, concretely relates to pneumatic flexible core assembly frock, including the pneumatic core assembly platform of four groups, pneumatic core assembly platform arranges respectively in the X of a plane core assembly platform and Y direction, and whenever two sets of arranges in opposite directions that the pneumatic core assembly platform of every group includes pneumatic cylinder, loam core locating piece, guide rail, governing valve, and pneumatic cylinder's piston passes through connecting rod and loam core positioning block connection, and the loam core locating piece is installed on the guide rail, and the governing valve communicates pneumatic cylinder. Still install the long -pending formula loam core locating piece of putting on the guide rail, loam core locating piece and the long -pending formula loam core positioning block connection of putting. The utility model has the advantages of 1, foundry goods to size precision expects much reduces and blocks phenomenon not in place, reduces the damage of fragility core group and scraps, 2, require not high foundry goods to size precision, the fit clearance of core print is also possible less relatively, and reducible loam core drunkenness improves the inner chamber size precision of foundry goods.

Description

A kind of Pneumatic flexible group core frock

Technical field

This utility model is related to casting technique field and in particular to a kind of Pneumatic flexible group core frock.

Background technology

Sand casting coremaking line has higher production efficiency, good casting dimension accuracy and casting quality and is easy to control The advantages of, with China from big country in foundry to striding forward that casting is made the country prosperous, coremaking line will be widely used in Foundry Production field.Group Core is one critical process in coremaking line, and existing group of core platform generally adopts fluid pressure type and high-pressure cylinder, and core group forces to put in place.But It is when core group is more, core print fit clearance is less, easily produces and block, lead to loam core to rupture, cause useless core；Between core print cooperation When gap is larger, loam core play, the inner chamber dimensional accuracy of impact foundry goods.

Utility model content

The purpose of this utility model is to solve the above problems, and provides a kind of Pneumatic flexible group core frock.

In order to realize the purpose of this utility model, the technical solution adopted in the utility model is：

A kind of Pneumatic flexible group core frock, including four groups of pneumatic group of core platforms, pneumatic group of core platform is arranged in a plane The group X of core platform and Y-direction, and every two groups arranged in opposite directions, every group of pneumatic group of core platform include pneumatic linear actuator, loam core locating piece, guide rail, Regulating valve, the piston of pneumatic linear actuator is connected with loam core locating piece by connecting rod, and loam core locating piece is arranged on guide rail, and regulating valve is even Logical pneumatic linear actuator.

Accumulative and travel type loam core locating piece is also equipped with guide rail, accumulative and travel type loam core locating piece is connected with loam core locating piece.

The beneficial effects of the utility model are：1st, for the foundry goods that dimension precision requirement is high, the fit clearance of core print Less with core group form and position tolerance, when group core runs unstable, occasional generation group core is not in place, is patted with handss, and unlikely Scrap in causing fragility core group to damage, reduce and block incomplete phenomena；2nd, for the foundry goods that dimension precision requirement is not high, core print Fit clearance relatively can also put less gap, to reduce loam core play, improve the inner chamber dimensional accuracy of foundry goods；3 and pass The fluid pressure type of system is compared with high-pressure cylinder, fragility core group will not be pressed firmly, block not in place or loam core play, reduce energy consumption Lose with useless core, and the higher foundry goods of dimensional accuracy can be obtained.

Brief description

Fig. 1 is this utility model structural representation.

Specific embodiment

With reference to the accompanying drawings and examples this utility model is further illustrated：

Embodiment：Referring to Fig. 1.

A kind of Pneumatic flexible group core frock, including four groups of pneumatic group of core platforms, pneumatic group of core platform is arranged in a plane Organize X and the Y-direction of core platform 1, and every two groups are arranged, every group of pneumatic group of core platform includes pneumatic linear actuator 2, loam core locating piece 3, leads in opposite directions Rail 4, regulating valve 5, the piston of pneumatic linear actuator 2 is connected with loam core locating piece 3 by connecting rod, and loam core locating piece 3 is arranged on guide rail 4 On, regulating valve 5 connects pneumatic linear actuator 2.

Accumulative and travel type loam core locating piece 6 is also equipped with guide rail 4, accumulative and travel type loam core locating piece 6 is connected with loam core locating piece 3.

This utility model specification：1st, loam core to be organized is respectively put into X on set of planes core platform, Y-direction each From in the loam core locating piece of pneumatic group of core platform, by loam core locating piece or accumulative and travel type loam core locating piece, loam core is positioned, loam core Locating piece connects accumulative and travel type loam core locating piece and provides pull strength；2nd, the equilibrium air pressure needed for using putting in place slightly larger than group core, opens The air pressure adjusting in valve regulation pneumatic linear actuator opening pneumatic group of core platform of each group carries out organizing core；3rd, confirm whether each loam core is organized core and put in place, Otherwise pat loam core with handss, until group core puts in place, and take the circumstances into consideration to tune up the pneumatic linear actuator pressure of this group by regulating valve.

According to product needed, single or multiple loam cores can be set in X-direction, same it is also possible to arrange in the Y direction single or Multiple loam cores.

This utility model Pneumatic flexible group core platform Typical Disposition is X and Y-direction, but is not limited to X, Y-direction, according to product Product require to increase pneumatic group of core platform of Z ... etc. multiple directions, are X, Y, Z etc. multiple directions realization group core.

What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto, the common skill of this area Art personnel, easily according to above-described embodiment, understand spirit of the present utility model, and make different amplifications and change, but as long as Without departing from spirit of the present utility model, all in protection domain of the present utility model.
