Specific embodiment

In conjunction with shown in attached drawing, a kind of shell mould overlapping casting tooling for casting nut of the utility model, it is characterised in that: including Tooling clamping plate, casting shell sand core main body 15, screw rod 5, nut 14, feeding sprue cup 4, tooling clamping plate include upper tooling clamping plate 8, Lower tooling clamping plate 9, casting shell sand core main body 15 are fixedly installed in tooling clamping plate 8, lower tooling folder by screw rod 5 and nut 14 Between plate 9；Casting shell sand core main body 15 is successively stacked from bottom to top by multiple shell mould sand cores and is constituted, a shell mould of the bottom Sand core is shell mould bed load core 7, and each shell mould sand core for successively overlaying 7 or more shell mould bed load core is the main sand core 6 of shell mould；Upper Feeding sprue cup 4 is set at medium position on tooling clamping plate 8.

It is respectively arranged with the screw rod mounting hole 13 matched with screw rod 5 on the upper tooling clamping plate 8, lower tooling clamping plate 9, Screw rod mounting hole 13 is convenient for fastening；Screw rod mounting hole 13 is four and is symmetricly set on tooling clamping plate, the four of upper tooling clamping plate 9 A screw rod mounting hole 13 is corresponding with four screw rod mounting holes 13 on lower tooling clamping plate 9；At the back side of upper tooling clamping plate 9 under Casting shell sand core main body 15 is fixedly mounted between the back side of tooling clamping plate 9.

The material of the upper tooling clamping plate 8, lower tooling clamping plate 9 is gray cast iron HT250, the upper tooling clamping plate 8, The thickness of lower tooling clamping plate 9 is 10mm.

Upper tooling clamping plate 8, lower tooling clamping plate 9 front on be also respectively provided with laterally with the reinforcing rib that vertically intersects 11。

Reserved sprue cup installation site 12 is equipped in the middle part of the upper tooling clamping plate 8, in reserved sprue cup installation site 12 Place's setting feeding sprue cup 4.

The casting shell sand core main body 15 is successively stacked from bottom to top by 2-20 shell mould sand core to be constituted.

The front of the shell mould bed load core 7, the main sand core 6 of shell mould is arranged with casting type chamber 1, the shell mould bed load core 7, the back side of the main sand core 6 of shell mould is arranged with running gate system 2；The middle part of each main sand core 6 of shell mould is the sprue 10 of perforation, shell The middle part of type bed load core 7 be closed sprue (position of the closed sprue in Fig. 3 and Fig. 4 be in Fig. 1 and Fig. 2 The corresponding position of sprue 10 of perforation that is drawn of middle part, i.e., what do not have picture all to represent closed sprue).

Weight loss groove 3 is provided between the back side upper system 2 of the shell mould bed load core 7, the main sand core 6 of shell mould.

Specifically, shell mould bed load core 7 and the production of the main sand core 6 of shell mould only need a set of hot box can be completed, and hot box is The coremaking tooling of shell mould sand core, the structural schematic diagram of hot box as shown in Figure 8.The system of shell mould bed load core 7 and the main sand core 6 of shell mould Make process: shell mould sand core is divided by shell mould bed load core 7 and the main sand core 6 of shell mould, coremaking when loose piece 16 is installed by disassembly loose piece 16 For the main sand core 6 of shell mould, sprue is perforation；Coremaking is shell mould bed load core 7 when loose piece 16 is dismantled, and sprue is closing；It saves in this way About hot box manufacturing cost and period, reduce the frequency that hot box is frequently replaced in coremaking, when reducing coremaker, Ke Yiti High efficiency reduces cost.

The shell mould bed load core 7 is used as the bed die of the main sand core 6 of shell mould successively stacked, and 7 middle part nothing of shell mould bed load core is directly poured Road avoids running away.The middle part of the main sand core 6 of each shell mould successively stacked is provided with the sprue 10 of perforation, fills type convenient for molten iron. The weight loss groove 3 can make sand core part loss of weight, reduce precoated sand usage amount.Sand core front is disposed with casting type chamber 1, sand core The back side be disposed with running gate system 2, a kind of sand core realizes two kinds of purposes.

The utility model reduces placer iron ratio, improves Technological adaptability, reduce by using above-mentioned technical proposal Castings production cost, improves production efficiency.

The utility model casts the assembling process of the shell mould overlapping casting tooling of nut are as follows: first puts shell mould bed load core 7 It is placed on the back side of lower tooling clamping plate 9, the height stacked is then changed according to 5 height of tooling screw rod or live constraint condition, it can To realize that 2-20 layers stack；The front of the back side of upper tooling clamping plate 8 towards the main sand core 6 of top layer's shell mould is put after the completion of stacking It sets, is then fastened with screw rod 5, nut 14, prevent lift case from causing to run away；Finally in the reserved sprue cup at upper 8 middle part of tooling clamping plate Feeding sprue cup 4 is placed at installation site 12, waits to be cast, entire assembling steps completion.

It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality Within novel protection scope.
