Abstract
The utility model relates to a casting mould structure combining bottom injection and rain-type injection. The casting mould structure comprises a lower box, a box cover and a stationary ladle, wherein a first middle box ring, a second middle box ring and a third middle box ring are arranged between the lower box and the box cover in sequence; mould cavities are arranged in the first middle box ring, the second middle box ring, the third middle box ring and the lower box; a core head is arranged in the lower box; the core head is communicated with the mould cavities; the core head is communicated with the stationary ladle by a lower-layer transverse pouring gate and a lower-layer straight pouring gate; an upper-layer transverse pouring gate and an upper-layer straight pouring gate arranged in the box cover are communicated with the stationary ladle; and a plug head is arranged at the inlet of the upper-layer straight pouring gate. After adopting the structure, by combining the bottom injection type structure and the rain-type structure, the casting mould structure disclosed by the utility model can reduce cold-shut and cold-shot phenomena of the product, can guarantee qualified rate of the product and can improve production efficiency.
Description
Technical field
The utility model relates to casting technology field, especially relates to a kind of bottom and injects and rain type injection combination casting mould structure.
Background technology
In casting industry, straight tube class cast casting is adopted to two kinds of ways conventionally, a kind of is horizontal moulding, another kind is vertical moulding.Laterally the advantage of moulding is mainly that moulding is simple and convenient, can save mould, and its shortcoming is that top box face is prone to defect in casting process, easily produces cold shut, occurs substandard products; The advantage of vertical moulding is mainly that yield rate is done, and is not easy to occur defect, is conducive to feeding, and its shortcoming is moulding difficulty in casting process, need to open circle moulding; For the larger straight barrel type foundry goods of length, as adopt horizontal moulding, in both ends of the surface, enter iron, the consequence causing is exactly foundry goods cold shut.Therefore can only adopt vertical moulding, in moulding, can only open several circles more, conventionally adopt bottom filling or rain type casting, adopt bottom filling, due to highly too high, the last mobility of molten iron is very poor, also can cause cold shut, and adopt rain type, highly too high, molten iron sweeps away and can produce the phenomenons such as cold shot, is unfavorable for formed product.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bottom of cold shut and cold shot phenomenon that there will not be and injects and rain type injection combination casting mould structure.
The technical scheme in the invention for solving the technical problem is: a kind of bottom is injected with rain type and injected combination casting mould structure, comprise nowel, case lid and seat bag, between described nowel and case lid, be provided with successively in sand frame in first, second sand frame in sand frame and the 3rd, in described first, in sand frame, second, in sand frame, the 3rd, in sand frame and nowel, be provided with die cavity, in described nowel, be provided with core print, core print is communicated with die cavity, and core print is communicated with seat bag by lower floor's cross gate and lower floor's sprue; In described case lid, be provided with upper strata cross gate and upper strata sprue and be communicated with seat bag, the porch of described upper strata sprue is provided with chock plug.
Further concrete, in sand frame and the 3rd, the junction of sand frame is provided with electric bell in described second.
The beneficial effects of the utility model are: after having adopted said structure, by bottom filling and rain type structure, combine, can reduce product and occur cold shut and cold shot phenomenon, can guarantee the qualification rate of product, and can enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, nowel; 2, sand frame in first; 3, sand frame in second; 4, sand frame in the 3rd; 5, case lid; 6, die cavity; 7, seat bag; 8, upper strata sprue; 9, upper strata cross gate; 10, lower floor's sprue; 11, electric bell; 12, lower floor's cross gate; 13, core print; 14, chock plug.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
A kind of bottom is injected with rain type and is injected combination casting mould structure as shown in Figure 1, comprise nowel 1, case lid 5 and seat bag 7, between described nowel 1 and case lid 5, be provided with successively in first in sand frame 2, second sand frame 4 in sand frame 3 and the 3rd, in described first, in sand frame 2, second, in sand frame 3, the 3rd, in sand frame 4 and nowel 1, be provided with die cavity 6, in described nowel 1, be provided with core print 13, core print 13 is communicated with die cavity 6, and core print 13 is communicated with seat bag 7 by cross gate 12He lower floor of lower floor sprue 10; In described case lid 5, be provided with upper strata cross gate 9 and upper strata sprue 8 and be communicated with seat bag 7, the porch of described upper strata sprue 8 is provided with chock plug 14; In described second, in sand frame 3 and the 3rd, the junction of sand frame 4 is provided with electric bell 11.
Iron liquid wraps 7 by seat, by lower floor's sprue 10, first flow to lower floor's cross gate 12, then through core print 13, in foundry goods die cavity 6, fill type, when iron liquid did not have in second that sand frame 3 is encountered electric bell 11 contact head, electric bell 11 sounds, now pull out seat bag 7 interior chock plugs 14, iron liquid stream flows to upper strata cross gate 9 by upper strata sprue 8, then in upper strata ingate injects die cavity 6.
Determine the time method of drawing the cork
1. computing method: the time while reaching foundry goods height 2/3 according to ingate flow rate calculation molten iron.
2. electric bell method: at foundry goods height 2/3 place, pre-buried electric bell both positive and negative polarity wire between two sand frames, when molten iron arrives herein, electric bell sounds, and extracts immediately chock plug.
The utility model adopts electric bell method, and relatively good control comparatively speaking uses computing method as standby simultaneously, in case electric bell breaks down, the time also must be extracted chock plug over after computing method 5S.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
