Description
Technical field
The present invention relates to a kind of large-scale bronze statue face integral casting method.
Background technology
Large-scale bronze statue face has complex-shaped, larger-size feature.Face's material is generally tin bronze, general to use
The mode of individual cast makes, can reduce make difficulty, each piece of castability of piecemeal is preferable, but the later stage be welded into it is whole
During block, then face's distortion is easily caused, post-processing work is also more complicated；If using the mode of monoblock cast, because size is big,
Rise and fall big, wall thickness is thin, is unfavorable for moulding by casting, the situation of local misrun easily occurs, therefore monoblock cast difficulty is larger.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned present situation, it is desirable to provide a kind of connection and reasonable arrangement, easy to operate, integrated poured effect
Good, practical large-scale bronze statue face integral casting method.
The implementation of the present invention is large-scale bronze statue face integral casting method, to comprise the following steps that：
1) plaster cast of large-scale bronze statue face is made,
2) make under casing sandbox, under casing sandbox shape selection square, according to plaster cast, consider gypsum mold size,
Each side mold thickness；
3) toward furan resin-sand, and ramming consolidation is filled out under casing sandbox, ensure that under casing sandbox fills up, unpacked after sand hardening
As under casing, under casing turn-over is lain against on workbench；
4) the thick leathers of 10mm are made with plasticine, are attached on turn-over under casing, toward top box sandbox in fill out furan resin-sand, system
Make top box；When making top box, diameter round steel is embedded to；
Spacing between top box and under casing is large-scale bronze statue face die cavity；
5) add cast sandbox on top box, make cross gate with foam, cross gate foam mold is put according to ingate position
Type, sprue pin is put among sandbox, fill out furan resin-sand in cast sandbox, produce running gate system case；
6) setting-out under casing and top box, makes a mark, and as the benchmark of mould assembling, unpacks and takes out plasticine, in top box
Round steel, cross gate and sprue pin, upper graphite alcohol-base paint, that is, it is molded ingate, cross gate and sprue；
7) sprue cup is made；Sprue cup is placed in sprue entrance；
8) mould assembling, and tin bronze liquid is poured into a mould from sprue cup, tin bronze liquid copper water flows into from sprue, horizontal is poured by netted
Road, ingate flow into bronze statue face die cavity, obtain large-scale bronze statue face.
Connection and reasonable arrangement of the present invention, easy to operate, integrated poured effect is good, practical.The present invention has successfully cast Jiangsu
The face of Liu meter Gao nation picture of Xuzhou Feng County 32, face area is more than 8m2, face thickness 10mm.

Embodiment
Comprised the following steps that below with Liu meter Gao nation of Xuzhou Feng County 32 as the making detailed description present invention of face：
1) Liu nation as shown in Figure 2 is made as the plaster cast of face, Liu nation are wide as the long 3200mm of face's plaster cast
2250mm, high 1350mm.
2) under casing sandbox is made, considers the versatility of under casing sandbox, under casing sandbox shape selection square, according to plaster mold
Type, consider gypsum mold size, each side mold thickness, the size of under casing sandbox is 4000mm × 4000mm × 300mm.Under casing sandbox
Total height should be higher than that model height, and round steel firm welding is used between under casing sandbox.
3) toward furan resin-sand, and ramming consolidation is filled out under casing sandbox, ensure that under casing sandbox fills up, unpacked after sand hardening
As under casing 1 (see Fig. 3), under casing turn-over is lain against on workbench (see Fig. 4).
4) the thick leathers of 10mm are made with plasticine, be attached on turn-over under casing 1.Complex-shaped position can increase thickness,
On under casing be capped case sandbox, toward top box sandbox in fill out furan resin-sand, produce top box 2.When making top box 2, diameter is embedded to
30mm round steel (see Fig. 5), the round steel of embedment is ingate 7.Ingate 7 is located at the lower position of face, face it is higher
Position mo(u)ld venting, discharged beneficial to type intracavity gas, guarantee is not in the situation of local misrun.Top box sandbox size is
4000mm×4000mm×280mm。
Spacing between top box 2 and under casing 1 is Liu nation as face's die cavity.
5) add running gate system case 3 on top box 2, cross gate 6 is made with foam, cross gate bubble is put according to ingate position
Foam model (see Fig. 6), sprue pin is put among sandbox (see Fig. 7).Furan resin-sand is filled out in cast sandbox, is produced
Running gate system case 3.Cross gate 6 should be arranged and reticulated, and ensure that connection is unimpeded.Ingate 7 is evenly arranged on cross gate 6.
To make cast smooth, it is desirable to which sprue, cross gate, ingate sectional area meet：In S sprue ＞ S cross gate ＞ S
Running channel.
6) setting-out under casing 1 and top box 2, makes a mark, the benchmark as mould assembling.Unpack and take out plasticine, in top box
Round steel, cross gate and sprue pin, upper graphite alcohol-base paint；It is molded ingate 7, cross gate 6 and sprue 5.
7) sprue cup is made；Sprue cup is placed in sprue entrance；
8) mould assembling, and pour into a mould tin bronze liquid from sprue cup, tin bronze liquid copper water flows into from sprue 5, horizontal is poured by netted
Road 6, ingate 7 flow into bronze statue face die cavity, obtain Liu nation shown in Fig. 2 as face.The tin bronze liquid pouring temperature 1180 ±
10℃。
The present invention has successfully cast the face of Liu meter Gao nation picture of Xuzhou Feng County 32, and face area is more than 8m2, face's thickness
Spend 10mm.
