Abstract
The utility model discloses a kind of crankshaft casting mould, comprise running gate system, die cavity and rising head, described running gate system comprises gate stick, cross gate, screen pack, main running channel, sprue and multiple ingate; Described die cavity is bent axle die cavity; Described rising head comprises the feeding head that is positioned at bent axle die cavity major part flange end and be connected with ingate and is positioned at the satrain relief of bent axle die cavity microcephaly center axle head, the neck of described feeding head is provided with the transition block being connected with bent axle die cavity major part flange end, and the upper/lower terminal of described satrain relief is connected with respectively the heat insulating block of a horizontally set.The utility model arranges transition block by the neck at feeding head, at the upper/lower terminal of satrain relief, heat insulating block is set simultaneously, dwindle the temperature difference between the rising head of two ends, thus solved existing die crank in casting process because the rising head excessive temperature differentials at die cavity two ends causes the poor problem of automatic modeling crankshaft casting product quality.
Description
Technical field
The utility model relates to technical field of mold, more particularly, relates in particular to a kind of crankshaft casting mould.
Background technology
Bent axle is one of vital part in automobile engine, and the quality of its performance directly has influence on quality and the life-span of automobile engine.The structure of existing automobile engine crankshaft is mainly by major part flange end, trunnion, rod journal, balance weight and microcephaly's central shaft composition, present stage, mostly adopt, at the major part flange end of mold cavity, feeding head is set, microcephaly's central shaft is set up the mode casting crankshaft of satrain relief, in casting process, due to the excess Temperature at feeding head place, and the temperature at satrain relief place is cooling too fast, cause the excessive temperature differentials between two rising heads, cause the metallographic structure of bent axle major part flange end poor, graphite form is thick, also make the difference of hardness at bent axle concentric reducer two ends to dwindle, poor 40 degree that reach of highest hardness, affect the quality of automatic modeling crankshaft casting product.
Utility model content
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, to provide a kind of crankshaft casting mould, solve existing die crank in casting process because the rising head excessive temperature differentials at die cavity two ends causes the poor technical problem of automatic modeling crankshaft casting product quality.
For achieving the above object, crankshaft casting mould provided by the utility model, comprise running gate system, die cavity and rising head, cross gate, the main running channel being communicated with cross gate that described running gate system comprises gate stick, be communicated with gate stick, be arranged on the sprue that cross gate is communicated with the screen pack of main running channel junction, with main running channel and be arranged side by side the multiple ingates on sprue; Described die cavity is the bent axle die cavity matching with bent axle shape and structure; Described rising head comprises the feeding head that is positioned at bent axle die cavity major part flange end and be connected with ingate and is positioned at the satrain relief of bent axle die cavity microcephaly center axle head, the neck of described feeding head is provided with transition block, this transition block is connected with the major part flange end of bent axle die cavity, the upper/lower terminal of described satrain relief is connected with respectively the heat insulating block of a horizontally set, and described heat insulating block coordinates with satrain relief the microcephaly center axle head of bent axle die cavity is enclosed in wherein.
The utility model arranges transition block by the neck at feeding head; utilize the major part flange end of transition block protection bent axle; avoid its hottest state in feeding head always; at the upper/lower terminal of satrain relief, heat insulating block is set simultaneously; utilize heat insulating block to slow down the cooling velocity of bent axle microcephaly center axle head; the temperature difference between the rising head (being feeding head and satrain relief) at bent axle die cavity two ends is dwindled, thus solved existing die crank in casting process because the rising head excessive temperature differentials at die cavity two ends causes the poor technical problem of automatic modeling crankshaft casting product quality.
Brief description of the drawings
Fig. 1 is top view of the present utility model.
In figure: 1-gate stick; 2-cross gate; 3-screen pack; The main running channel of 4-; 5-sprue; 6-ingate; 7-feeding head; 8-transition block; 9-bent axle die cavity; 10-satrain relief; 11-heat insulating block.
Detailed description of the invention
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 1, a kind of crankshaft casting mould provided by the utility model, comprise running gate system, die cavity and rising head, cross gate 2, the main running channel 4 being communicated with cross gate 2 that described running gate system comprises gate stick 1, be communicated with gate stick 1, be arranged on the sprue 5 that cross gate 2 is communicated with the screen pack 3 of main running channel 4 junctions, with main running channel 4 and be arranged side by side the multiple ingates 6 on sprue 5; Described die cavity is the bent axle die cavity 9 matching with bent axle shape and structure, and automatic modeling crankshaft casting is casting in this die cavity; Described rising head comprises the feeding head 7 that is positioned at bent axle die cavity 9 major part flange ends and be connected with ingate 6 and the satrain relief 10 that is positioned at bent axle die cavity 9 microcephaly center axle heads, the neck of described feeding head 7 is provided with transition block 8, this transition block 8 is connected with the major part flange end of bent axle die cavity 9, the upper/lower terminal of described satrain relief 10 is connected with respectively the heat insulating block 11 of a horizontally set, and described heat insulating block 11 coordinates with satrain relief 10 the microcephaly center axle head of bent axle die cavity 9 is enclosed in wherein.
When casting, the molten metal of melting injects mould from gate stick 1, be drained to screen pack 3 by cross gate 2, under the effect of screen pack 3, remove by filter the impurity in molten metal, enter main running channel 4, molten metal will overflow to sprue 5 after being full of main running channel 4 again, and branches to each ingate 6, enter bent axle die cavity 9 through feeding head 7, transition block 8, in die cavity, complete the casting of automatic modeling crankshaft casting.
Owing to being provided with transition block 8 at the neck of feeding head 7, transition block 8 flows to from feeding head 7 at molten metal the process of bent axle die cavity 9 and plays transition buffer effect, for the protection of the major part flange end of automatic modeling crankshaft casting, avoid its hottest state in feeding head 7 always, solved existing die crank causes bent axle major part flange end in the casting process problem that metallographic structure is poor, graphite form is thick because of feeding head place excess Temperature; And the heat insulating block 11 that is arranged on satrain relief 10 places plays insulation effect to the microcephaly center axle head of automatic modeling crankshaft casting, in order to slow down the cooling velocity of microcephaly center axle head, the temperature difference between feeding head 7 and satrain relief 10 is dwindled, thereby dwindle the difference of hardness at large and small two ends of automatic modeling crankshaft casting, bent axle quality is ensured.
