Abstract
The utility model provides a kind of shell structure of magnesium iron as cast condition bent axle, comprise shell mould body, two pouring in vertically clamped moulds die cavities arranged side by side are provided with in described shell mould body, described pouring in vertically clamped moulds cavity bottom is connected with running channel, described pouring in vertically clamped moulds die cavity top is provided with rising head, the axle journal of each described pouring in vertically clamped moulds die cavity is other is provided with multiple chill, and described chill is positioned at the thermal center place outside axle journal.By arranging chill on shrinkage porosite position axle journal side, solve the defect of the Micro shrinkage among a small circle that crankshaft journal place causes because of local thermal center, thus avoid and scrap because high-frequency quenching cracks on user's processing line, and then reach the quality improving product, the object of rate of reducing the number of rejects and seconds.
Description
Technical field
The utility model relates to casting mold field, particularly relates to a kind of shell structure of magnesium iron as cast condition bent axle.
Background technology
At present, the lightweight for engine is considered, the structure of bent axle is compacter, thus makes the local thermal center of the dispersion of bent axle increase.In bent axle casting mold process, traditional feeding system is difficult to thoroughly solve such defect---the Micro shrinkage defect at automatic modeling crankshaft casting axle journal place, the requirement raising of high-frequency quenching is carried out at this position simultaneously, namely the depth down quenched, area strengthen, and then make the scrappage easily cracked because of the Micro shrinkage at axle journal place during bent axle high-frequency quenching up to 30%.
In order to provide the automatic modeling crankshaft casting of high-quality, adopting traditional casting technique and melting, pouring technology cannot reach the requirement of client, therefore corresponding improvement being carried out to the casting technique of foundry goods and become those skilled in the art's technical barrier in the urgent need to address.
Utility model content
Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, and providing a kind of can carry out local Quench to bent axle Micro shrinkage position and accelerate the shell structure of the magnesium iron as cast condition crankshaft casting cooling effect.
For achieving the above object and other relevant objects, the utility model provides a kind of shell structure of magnesium iron as cast condition bent axle, comprise shell mould body, two pouring in vertically clamped moulds die cavities arranged side by side are provided with in described shell mould body, described pouring in vertically clamped moulds cavity bottom is connected with running channel, described pouring in vertically clamped moulds die cavity top is provided with rising head, and the axle journal of each described pouring in vertically clamped moulds die cavity is other is provided with multiple chill, and described chill is positioned at the thermal center place outside axle journal.
Further, described running channel comprises the vertical running channel between cross gate and two pouring in vertically clamped moulds die cavities be connected with described pouring in vertically clamped moulds cavity bottom, and described cross gate communicates with vertical running channel, and described vertical running channel top arranges quantitative cup.
Further, the axle journal of each described pouring in vertically clamped moulds die cavity is other is provided with five chills.
Further, the volume of described rising head is 120cm
3, the modulus of rising head is 5mm.
Further, the thickness of described chill is 42mm.
Further, the modulus of described riser neck is 2.5mm.
By above technical scheme, the utility model has following technique effect compared to prior art: by arranging chill on shrinkage porosite position axle journal side, solve the defect of the Micro shrinkage among a small circle that crankshaft journal place causes because of local thermal center, thus avoid and scrap because high-frequency quenching cracks on user's processing line, and then reach the quality improving product, the object of rate of reducing the number of rejects and seconds.

Fig. 1 is structural representation of the present utility model.
Element numbers illustrates:
1 shell mould body
2 rising heads
3 riser necks
4 pouring in vertically clamped moulds die cavities
5 chills

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Magnesium iron as cast condition bent axle of the present utility model have employed as cast condition hi-strength nodular iron QT800, consult shown in Fig. 1, shell structure comprises shell mould body 1, two pouring in vertically clamped moulds die cavities 4 are provided with in shell mould body 1, because this shell mould adopts pouring in vertically clamped moulds technique, so be connected with cross gate 6 bottom two pouring in vertically clamped moulds die cavities 4, the vertical running channel 7 arranged between cross gate 6 with two pouring in vertically clamped moulds die cavities communicates, and vertical running channel 7 top arranges quantitative cup 8.Two pouring in vertically clamped moulds die cavity 4 tops are communicated with rising head 2 by riser neck 3.The volume of rising head 2 is 120cm3, and modulus is 5mm (modulus=volume/surface area).Riser neck 3 modulus is 2.5mm.Choked flow sectional area according to calculating each foundry goods is: F=675mm2, and be the cooling effect preventing sand washing from simultaneously taking into account riser feeding effect and chill, every type fills the 10 seconds time of type.The axle journal of pouring in vertically clamped moulds die cavity is other arranges chill 5, and namely each die cavity is other arranges 5 chills, and chill can all be removed when casting cleaning, and the thickness of chill is 42mm.
Using shell structure of the present utility model to pour into a mould automatic modeling crankshaft casting can one-shot forming 2 foundry goods, owing to employing 10 chills, the internal soundness (Micro shrinkage) at the axle journal place of automatic modeling crankshaft casting is obtained solve thoroughly, the percent defective that automatic modeling crankshaft casting is cracked during bent axle high-frequency quenching on user's processing line is from original 30%, be reduced to current less than 0.5%, greatly reduce production cost and quality cost, achieve good economic benefit, also meet the needs of client.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
