Description
Technical field
The utility model relates to part technical field of processing equipment, specially a kind of monoblock type compressor crank shaft blank casting
Modeling type.
Background technique
Crankshaft is most important component in engine；It bears the power that connecting rod transmits, and is transformed into torque and passes through song
Axis exports and other attachmentes on engine is driven to work；Crankshaft is by the centrifugal force of gyrating mass, the gas inertia of mechanical periodicity
The collective effect of power and reciprocal inertia force makes crankshaft bear the effect of flexion torsion load；Therefore it is required that crankshaft have it is enough strong
Degree and rigidity, journal surface need are wear-resisting, work is uniform, balance；Generated centrifugal force when to reduce crankshaft quality and movement,
Crankshaft journal is often made hollow；It is provided with oilhole in each journal surface, to introduce or draw machine oil, to moisten
Sliding journal surface；It is concentrated to reduce stress, the junction of trunnion, crank-pin and crank arm all uses transition arc to connect；It is bent
Spindle balance weight (also referred to as counterweight) effect be for balance rotating centrifugal force and its torque, can also balance sometimes reciprocal inertia force and
Its torque；When these power and torque itself reach balance, balance weight may further be used to mitigate the load of base bearing；The number of balance weight
Mesh, size and installation position will be according to numbers of cylinders, cylinder spread pattern and crankshaft shape of engine etc. because usually considering；Balance
Weight is generally integral with crankshaft casting or forging, and high-power diesel engine balance weight is separately manufactured with crankshaft, is then connected with
Together.
But existing crankshaft generally uses clay sand mold mould during production, this makes crankshaft be of rude workmanship,
Precision is not high, so that the processes such as postorder polishing, polishing are various, trivial operations.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of monoblock type compressor crank shaft blank casting pattern
The existing crankshaft proposed in background technique causes crankshaft to be of rude workmanship during production using clay sand mold mould, precision
Not high problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of monoblock type compressor crank shaft blank
Casting pattern, including upper die crank and lower die crank, the upper die crank and lower die crank are bolted, institute
It states die crank and pours slot equipped with upper die crank, and upper die crank is equipped with casting gate, on the lower die crank
Slot is poured equipped with lower die crank, the lower die crank is equipped with groove, and groove is equipped with U-lag, the lower crankshaft mould
Thermal vias and tapped through hole are equipped on tool and upper die crank.
Preferably, it is bulge-structure that the upper die crank, which pours slot, and upper die crank pour the bulge-structure of slot with
Groove composition is mutually twisted structure.
Preferably, the casting gate is circular pipe, and casting gate and U-lag composition are mutually twisted structure.
Preferably, the thermal vias is equipped with two groups, and thermal vias is equally evenly distributed.
Preferably, the upper die crank pours slot and lower die crank pours slot lower end and is equipped with heat-conducting pad, and leads
Heat pad piece is high pressure asbestos rubber material.
Compared with prior art, the utility model has the beneficial effects that the monoblock type compressor crank shaft blank casting die
Type replaces clay sand mold mould using alloy mold, and alloy mold is divided into two parts, freely assembled or fractionation, so that should
Alloy mold easily takes out after not only having the advantages that the cooling and shaping of clay sand mold mould inside crankshaft, turns inward the alloy mold
After axis is cooled and shaped, after the clay sand mold mould inside crankshaft that compares is cooled and shaped, precision is higher, and it is more careful to do manual work, and the alloy
Mold can be used for multiple times, and save the cost improves efficiency.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of monoblock type compressor crank shaft blank casting
Model, including upper die crank 1 and lower die crank 2, upper die crank 1 and lower die crank 2 are connected by bolt 6, upper song
Axle mould tool 1 is equipped with upper die crank and pours slot 3, and upper die crank 1 is equipped with casting gate 5, and casting gate 5 is circular pipe,
And casting gate 5 and the composition of U-lag 9 are mutually twisted structure, this is kept fixed casting gate 5, prevents high temperature low-sulfur pure
Molten iron spills during pouring, and accident occurs, and lower die crank 2 is equipped with lower die crank and pours slot 4, lower die crank
2 are equipped with groove 8, and groove 8 is equipped with U-lag 9, and it is bulge-structure that upper die crank, which pours slot 3, and upper die crank pours
The bulge-structure of slot 3 and the composition of groove 8 are mutually twisted structure, this make using bolt 6 by upper die crank 1 and lower crankshaft mould
After 2 connection of tool, upper die crank pours slot 3 and can stick into groove 8, pours slot 4 with lower die crank and is docked, not only
The accuracy that may insure docking, while can prevent from deviating in casting process, cause die crank pour slot 3 with
Lower die crank pours slot 4 and is staggered, so that biggish error occurs in crankshaft after molding, upper die crank pours slot 3 and lower song
Axle mould tool pours 4 lower end of slot and is equipped with heat-conducting pad 11, and heat-conducting pad 11 is high pressure asbestos rubber material, this makes by leading
11 transition temperature of heat pad piece can uniformly reduce the temperature at each position of crankshaft, improve molding after crankshaft intensity and
The ability of resistance to deformation is equipped with thermal vias 7 and tapped through hole 10, thermal vias 7 on lower die crank 2 and upper die crank 1
Equipped with two groups, and thermal vias 7 is equally evenly distributed, this allows air by circulating between thermal vias 7, takes away
Heat, the time that crankshaft is cooled and shaped shorten, and improve working efficiency.
Working principle:, first will be on upper die crank 1 when using the monoblock type compressor crank shaft blank casting pattern
Upper die crank pour slot 3 and stick into the groove 8 on lower die crank 2 so that upper die crank pours slot 3 and lower crankshaft mould
Tool pours slot 4 and accurately docks, and forms one and completely pours slot, fixed across tapped through hole 10 followed by bolt 6, by upper song
Axle mould tool 1 and the connection of lower die crank 2, then the pure molten iron of high temperature low-sulfur is poured into, finally wait high temperature low-sulfur by casting gate 5
Pure molten iron is cooled and shaped, and is backed out bolt 6, upper die crank 1 and lower die crank 2 is dismantled, that is, after can be taken off cooling and shaping
Crankshaft, the above are the use processes of the monoblock type compressor crank shaft blank casting pattern.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
