2) blade bottom loose tool type is set level on platform, blade wooden model is placed on the loose tool type of bottom, face of blade upward, uses core
Box frame is by including blade wooden model shroud；
3) place reinforcing bar on blade wooden model surface, be welded into network structure arbor；
4) lower panelgirder is placed on above lower core box, arbor is connected with lower panelgirder；
5) back-up sand face of blade integral sand core；
6) after the hardening of front core, lower panelgirder and front integral sand core turn-over make lower panelgirder be placed on platform, blade wood
The mould back side is upward；
7) lower core box is covered on again lower core outer surface, upper core box is positioned in lower core box, perimeter alignment；
8) weld arbor in blade wooden model backside surface；
9) upper panelgirder is placed on above upper core box, and is connected with back side arbor；
10) back-up sand vacuum side of blade integral sand core；
11), after core hardening, remove core box frame, back side core of slinging, upset is placed on platform, takes out blade wooden model；
12) sand mold, spray paint, drying, mould assembling are repaired；
13) upper and lower panelgirder clamp and reinforcing bar are strained firm welding；
14) it is placed horizontally in pit, vertically erect；
15) moulding by casting.
Compared with prior art, the invention has the beneficial effects as follows：
The present invention replaces thick and heavy sandbox with upper and lower panelgirder, alleviates the weight of whole sand mold, produces and is not subject to crane gear
Energy power restriction, improves production capacity.And the panelgirder flexible versatility of tool, reusable edible, cost-effective.
