Below with reference to Fig. 1-Fig. 2 descriptions according to the concrete structure of the casting grain mold 100 of the utility model embodiment.
As shown in Figure 1, including ontology 110, the upper table of ontology 110 according to the casting grain mold 100 of the utility model embodiment
Face is equipped with charging groove 111, feeds and offers casting slot 112 on the bottom wall of groove 111, and casting slot 112 is multiple, multiple casting
Slot 112 is arranged in multiple rows of multiple row, and casting slot 112 is formed as semielliptical type.
It is understood that the upper surface of ontology 110 is equipped with charging groove 111, feeds and opened up on the bottom wall of groove 111
There is casting slot 112, since casting slot 112 is not directly arranged in the upper surface of ontology 110, but is located at charging groove 111
On bottom wall, molten metal liquid splash in casting process can be prevented in this way, improves security performance.Due to slot 112 of casting
Be formed as semielliptical shape, the casting slot 112 of this shape is very beneficial to demould, that is to say, that after the completion of casting, this practicality is new
The casting grain mold 100 of type embodiment without beat can automatic demoulding, extend the service life of casting grain mold 100, improve
Casting grain efficiency.
Casting grain mold 100 according to the ... of the embodiment of the present invention, since the upper surface of ontology 110 is equipped with charging groove 111, into
Expect to offer casting slot 112 on the bottom wall of groove 111, it is therefore prevented that molten metal liquid splash in casting process improves peace
Full performance, while the casting slot 112 of semielliptical shape is conducive to demould, and extends the service life of casting grain mold 100, improves casting
Grain efficiency.
In some embodiments, the long axis length of casting slot 112 is D, and minor axis length d, D and d meet relational expression：20mm
≤ D≤100mm, 8mm≤d≤70mm, and 0.4≤d/D≤0.7.It is understood that the value of d/D is smaller, then slot 112 of casting
Oval cross section it is more sharp, be unfavorable for alloy granule demoulding in this way, be as a result, conducive between 0.4-0.7 the control of the value of d/D
Alloy granule demoulds.Advantageously, 30mm≤D≤50mm, 12mm≤d≤35mm.
In some embodiments, the depth of casting slot 112 is H, and H meets relational expression：8mm≤H≤20mm and 0.2≤H/D
≤0.4.It is understood that casting slot 112 is deeper, demoulding difficulty is bigger, but slot 112 of casting is excessively shallow, can lead to alloy granule
It is relatively thin.Therefore by the deep-controlled in the range of 8-20mm of slot 112 of casting, it not only can guarantee demoulding difficulty but also can ensure alloy
The size of grain.
In some embodiments, on the length direction of charging groove 111, the number of casting slot 112 is 6 to 10,
In the width direction of charging groove 111, the number of casting slot 112 is 3 to 5.It is understood that casting slot 112
Number can cause casting grain mold 100 larger too much, not only increase the manufacturing cost of casting grain mold 100, while also increase casting
The energy consumption of grain machine, the excessively few casting grain efficiency that can then reduce casting grain machine of casting slot 112.Therefore in the length direction of charging groove 111
On, the number of casting slot 112 is 6 to 10, and in the width direction of charging groove 111, the number of casting slot 112 is 3
To 5, the production cost of casting grain mold 100 can be not only controlled in this way, but also can ensure to cast grain efficiency.
In some embodiments, the spacing between adjacent two casting slots 112 is L, and L meets relational expression：20mm≤L≤
100mm.It is understood that the excessive size that will increase casting grain mold 100 of spacing between two neighboring casting slot 112, from
And the production cost of casting grain mold 100 is promoted, but spacing between two neighboring casting slot 112 is too small to cause alloy melt
Crossfire, and the thin-walled between two casting slots 112 is easily damaged.Therefore L is controlled between 20-100mm ranges not only
The production cost of casting grain mold 100 can be controlled, and can guarantee the service life of casting grain mold 100.Advantageously, 40mm≤L≤
60mm。
In some embodiments, the solid volume of ontology 110 is V1, and the sum of volumes of multiple casting slots 112 is V2, V1 and
V2 meets relational expression：0.04≤V2/V1≤0.21.It is understood that the value of V2/V1 is excessive, the caloric receptivity of casting grain mold 100
The thermal discharge of melt is cannot be satisfied, casting grain 100 temperature of mold can be caused excessively high, causes to continue the cooling speed of alloy melt when casting
Spend it is slower and slower, coagulation result worse and worse, formed vicious circle, the value of V2/V1 is excessive too small, increases mold weight, increase
Manufacturing cost, while increasing casting grain machine operation power consumption.Preferably 0.07≤V2/V1≤0.12 can both ensure alloy in this way
The cooling velocity of melt, and control the manufacturing cost of casting grain mold 100 and cast the operation power consumption of grain machine.
In some embodiments, the depth of charging groove 111 is h, and h meets relational expression：60mm≤h≤120mm.It can manage
Solution, the depth for feeding groove 111 is excessively shallow, alloy melt splash or spilling when be easy to causeing casting, feeds 111 mistake of groove
It is deep then increase manufacturing cost.Preferably, 80mm≤h≤100mm, can both prevent in this way casting when alloy melt splash or
Person is overflowed, and can control the manufacturing cost of casting grain mold 100.
In some embodiments, it is respectively equipped with mounting ear 120 on the opposite exterior lateral sides wall of ontology 110.Thus, it is possible to facilitate casting
The installation of grain mold 100.Certainly, the shape of mounting ear 120 can be formed as arbitrary shape, herein not to the shape of mounting ear 120
Shape makes specific restriction.
Specifically, each mounting ear 120 is connect by arc transition with ontology 110.Mounting ear 120 is reduced as a result,
With the stress of 110 junction of ontology, reduces mounting ear 120 and the risk being broken occur.
In some embodiments, casting grain mold 100 is made of high temperature resistant and the fast material that conducts heat, it is desirable that maximum operation (service) temperature
It is preferred to be not less than 1000 DEG C not less than 900 DEG C.
