Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
The cast structure preventing casting crack and plane deformation as shown in Figure 1, Figure 2, Figure 3, Figure 4, including interconnecting
Door-hinge 1 and door-plate 2, also include the combined type anticracking shrinkage rib 3 being at least made up of, described combined type two-layer reinforcing plate structure stacking
Anticracking shrinkage rib 3 transition is arranged at the right angle joint between door-hinge 1 and door-plate 2, each layer of described combined type anticracking shrinkage rib 3
Gusset cross-sectional area size between reinforcing plate structure differs.
Bright spot of the present utility model is in the case of constant to existing structure, straight by foundry goods door-hinge 1 and door-plate 2
Junction, angle increases combined type anticracking shrinkage rib 3, avoids stress or the postorder heat treatment of molten steel contraction generation during casting solidification
Residual stress, by drawing crack at this, solves the crack problem of right angle.
When pouring of reality, it is preferred to use inclined casting, this is possible not only to improve molten steel static pressure, strengthens molten steel flow
Property, it is also possible to make gas in die cavity discharge from rising head in time, solve former technique misrun problem.Meanwhile, rising head hole irrigation system is set up
System, it is ensured that in casting process, rising head temperature is higher, strengthens the thermograde of foundry goods, for reaching rational consecutive solidification manufacture
Advantage.Reduce foundry goods shrinkage stress and improve casting deformation.Additionally, when cast, by padded necessarily for sandbox rising head side
Highly, it is ensured that sandbox angle of inclination is in certain limit, and intakes from the main cast gate of low level during cast, and molten steel flows to high-end from low side,
In whole casting process, running gate system remains full state.It is poured into after liquid level in rising head rises to certain altitude, switching
Hole irrigation is carried out to rising head hole irrigation system, until casting complete.Rising head hole irrigation system ensures in casting process, and rising head temperature is relatively
High.Make to keep incremental thermograde away from rising head to rising head, reach rising head final set, it is achieved consecutive solidification, thus obtain
Dense structure, perfect foundry goods without shrinkage cavity.After cast, heat treatment complete, only need to simply remove described combined type and prevent
Split shrinkage rib 3.
General, as shown in Figures 2 and 3, described combined type anticracking shrinkage rib 3 is by two outer layers reinforcing plate structure 32 and sets
Intermediate layer reinforcing plate structure 31 stacking being placed between described two outer layers reinforcing plate structure 32 is constituted.Door-hinge 1 is straight with door-plate 2 junction
Angle uses certain thickness circular arc R b transition to constitute composite reinforcing root structure i.e. outer layer reinforcing plate structure 32, and reducing casting with this should
Power.Meanwhile, intermediate layer reinforcing plate structure 31 is set on door-hinge 1 with door-plate 2 right angle joint transition arc Ra and constitutes compound
Muscle main body.Composite reinforcing main body and the circular arc R c transition of root intersection.Composite reinforcing and door-hinge 1 and door-plate 2 joint are with relatively Rouno Cormer Pregrinding Wheel
Transition.Due to the construction features that composite reinforcing is special, main body solidification is fast, defines an orientation between composite reinforcing and door-hinge door-plate
Consecutive solidification, composite reinforcing main body intensity sets up relatively foundry goods body earlier, when casting solidification, it is possible to bear bigger tension.
The crackle that when avoiding casting solidification, molten steel shrinkage stress causes at this, reduces the deformation of foundry goods door-hinge simultaneously.General, such as figure
Shown in 3, the cross-sectional area of described intermediate layer reinforcing plate structure 31 is more than the cross-sectional area of outer layer reinforcing plate structure 32, and effect is more
Good.
It addition, another spotlight of the present utility model is to be improved further with being applied in combination of dark chill by internal densener
Casting effect.Concretely, by setting up internal densener pole 4, will be socketed in door-hinge 1 by described internal densener pole 4, make door-hinge
According to rational consecutive solidification at 1, alleviate door-hinge 1 part and produce the tendency of the casting flaw such as shrinkage porosite, shrinkage cavity, reduce simultaneously
Shrinkage stress, reduces the crackle tendency of door-hinge 1 and door-plate 2 junction.Meanwhile, that sets up outside door-hinge 1 is the coldest
Iron construction 5, is mutually matched with the dark frozen iron blocks on sand mold, so that foundry goods reaches the purpose of consecutive solidification, and to a certain degree
Upper reduction door-hinge 1 is inclined to the crackle of door-plate 2 junction.Wherein, the material of internal densener pole 4 is consistent with castings material, surface
Must be processed by shot blasting, door-hinge is outside coordinates the dark chill put for increasing rising head effective compencation distance.
Ingenious design of the present utility model on the premise of ensureing to solve existing foundry goods misrun and plane deformation problem,
Required cost of manufacture and difficulty of processing are the most relatively low, but can obtain very good technique effect, for improving enterprise
The effect of benefit is the most fairly obvious, has the most wide marketing prospect.
