Description
Technical field
The utility model relates to sand casting technical field, is a kind of flask overturning device of moulding machine specifically.
Background technology
The key link of sand casting is moulding, and the core of moulding machine is sand densifying mechanism.Squeeze moulding machine a kind ofly should have the low speed sand densifying mechanism of history decades in producing, and its sand densifying mechanism is comparatively simple, but the low and skewness of compacting gained sand mold compactability; Formed clamp plate compacting is conducive to the uniformity improving model top and surrounding sand mold compactability; But in a word, squeeze mo(u)lding gained sand mold compactability is lower, and particularly the sand mold die joint degree of packing is on the low side, and gained casting dimension accuracy is low, and surface quality is poor.
Clay-bonded sand metal casting is a kind of conventional of sand casting and the good a kind of formative method of cast member quality.Clay-bonded sand metal casting is shaping is one of main production process of automobile, hot-water heating and hardware blank, is widely used, and occupies critical role in machine building industry.Wherein the making of clay-bonded sand sand mold is one of key link in castings production technical process, the making quality of sand mold is directly connected to quality and the yield rate of foundry goods, to raising casting quality, reduce casting cost and play vital effect, developed countries is all kinds of high-end automatic molding machine for this formative technology have developed, this kind of machinery has that production efficiency is high, steady quality, energy-conserving and environment-protective advantage, but because of it, prices are rather stiff, maintenance difficulties is large, is difficult to promote the use of in common customer.
Most domestic foundry enterprise is still using technique jolt-squeeze machine simple, backward in technique or squeeze molding machine to carry out sand mold making, when carrying out sand mold and making, a kind of mode manufacturing sand mold is had to be that upper and lower mould is produced continuously, this just need overturn casting sandbox, so that carry out the making of next sand mold, and the method for traditional turning device sandbox is all adopt manually to overturn, its labour intensity is larger, that artificial upset obviously seems bothersome effort when larger casting sandbox need be overturn.
Summary of the invention
In order to make up the deficiencies in the prior art, the utility model provides a kind of flask overturning device of moulding machine, can be turned by casting sandbox very easily, reduce the labour intensity of workman.
The utility model solves the technical scheme that its technical problem adopts: a kind of flask overturning device of moulding machine, comprises workbench and turning device, described driving water placing flat, and the workbench left and right sides is centrosymmetric offers through hole.
Described turning device comprises two pneumatic cylinders and two fixed mounts, described pneumatic cylinder is vertically arranged, pneumatic cylinder comprises cylinder body and piston rod, and described cylinder body lower surface is connected with base plate, described piston rod is positioned at cylinder interior, and the end of piston rod is connected with fixed mount; Described turning device is positioned at immediately below described through hole, and piston rod and fixed mount can pass through hole, and the lower surface of turning device is connected with base plate, turning device for overturning sandbox so that carry out another side add sand molding.By hoisting piston bar, make piston rod drive fixed mount to rise, thus lift sandbox, the certain position until sandbox is picked up, then overturns sandbox, is slowly fallen by piston rod and makes piston rod get back to origin-location, realizing the rollover effect of sandbox.
Described fixed mount is provided with up big and down small parabola shaped holddown groove, the inner surface of holddown groove is through modifier treatment.
Described piston rod and fixed mount can pass through hole.
The air chamber of two described pneumatic cylinders is connected, and adopts law of connected vessels, realizes two pneumatic cylinder synchronization actions, prevent the generation of useless mould.
The beneficial effects of the utility model are: the flask overturning device of a kind of moulding machine of the present utility model, sandbox can lift by described turning device, sandbox is overturn, instead of the process of artificial upset sandbox, the labour intensity of workman can be reduced and boost productivity; Fixed mount of the present utility model is provided with up big and down small parabola shaped holddown groove, the sand box handle of different-diameter size can be adapted to; Structure of the present utility model is simple, reasonable in design, is easy to be extended and applied.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1 to Figure 3, the flask overturning device of a kind of moulding machine described in the utility model, comprises workbench 1 and turning device 4, described workbench 1 horizontal positioned, and workbench 1 left and right sides is centrosymmetric offers through hole 12.
Described turning device 4 comprises two pneumatic cylinders 41 and two fixed mounts 42, described pneumatic cylinder 41 is vertically arranged, pneumatic cylinder 41 comprises cylinder body 411 and piston rod 412, described cylinder body 411 lower surface is connected with base plate 2, it is inner that described piston rod 412 is positioned at cylinder body 411, and the end of piston rod 412 is connected with fixed mount 42; Described turning device 4 is positioned at immediately below described through hole 12, and piston rod 412 and fixed mount 42 can pass through hole 12, and the lower surface of turning device 4 is connected with base plate 2, turning device 4 for overturning sandbox so that carry out another side add sand cast.By hoisting piston bar 412, make piston rod 412 drive fixed mount 42 to rise, thus lift sandbox, the certain position until sandbox is picked up, then overturn sandbox, slowly piston rod 412 fallen and make piston rod 412 get back to origin-location, achieving the rollover effect of sandbox.
